With the click of a mouse, you can order any protein powder, and it’ll arrive at your doorstep in a matter of days. This is great news since protein is an essential macronutrient that may help repair muscle tissue for strength gains, can keep you satiated, and may balance your hormones.
In 2020, the global whey protein powder market was valued at $9.4 billion and is estimated to grow to $18.4 billion by 2027. Whey protein of all types — from whey isolate to whey concentrate — may be flying off of the shelves almost as fast as pre-workout. But what isn’t always certain is which brand is right for you. There is a seemingly endless number of protein powder options, but some may not be suited for your goals or lifestyle. Fear not, we’ve tested out dozens of protein powder supps, from the biggest sellers to the little-known underdogs, and developed this list to help you find the best whey protein powder to meet your needs.

You can also check out this video from BarBend, where former Nutrition Editor Nick English goes over a variety of whey protein powders and their benefits. He walks you through each pick and why we chose it as a favorite.
Best Whey Protein Overall
A solid whey protein will have a balanced formula that offers a high dose of protein with minimal fat, and a low dose of carbs — this pick is just that. Plus, it comes with higher protein than most other powders.
Transparent Labs Whey Protein Powder
With so many protein powders on the market, it can be difficult to pick our favorite, but thankfully Transparent Labs made the decision easier with their top-notch product. It features a higher protein dose than most other powders on the market at 28 grams of high-quality whey isolate per serving. They also keep the other macros low with only one gram of carbs per serving and no fat. Plus, you’ll receive a handful of potentially helpful micronutrients like calcium, iron, and potassium.
With 8 different flavors and 28 grams of whey protein from hormone-free, grass-fed cows, Transparent Labs Whey Protein Isolate is an excellent way to hit your protein macros.
This protein’s lean formula makes it great for mixing into shakes, baking with, and drinking plain with water or milk. If you like to shake things up (no pun intended), Transparent Labs makes their protein in eight different tasty flavors with unique options like Cinnamon French Toast and Oatmeal Chocolate Chip Cookie. The price is slightly higher than some other protein powders at around $59.99, which works out to about $2.00 per serving.
Who Should Buy Transparent Labs Whey Protein Powder
- Anyone who is trying to burn fat. This supplement delivers protein with little to no extra macronutrients.
- People who like to change up their protein flavors often will appreciate the eight different unique flavors to choose from.
- If you’re looking for additional micronutrients, this powder contains calcium, iron, and potassium.
Who Shouldn’t Buy Transparent Labs Whey Protein Powder
- People looking to bulk up may want a more caloric, carb-heavy whey protein formula as this only has 120 calories and one gram of carbs per serving.
- Anyone who wants to buy a lot of protein powder at once. Transparent Labs only sells 30-serving tubs. (Of course, you can purchase multiple tubs at once, but they don’t offer any bulk deals.)
- Those on a budget may want to opt for a less expensive formula.
This formula is simple but delivers what most people looking for a protein powder want — a solid amount of protein, low carbs, no fat, and a reasonably short ingredients list. You can also select from eight delicious flavors, which is a pretty great variety.

Best Whey Protein for Men
For men who are looking to pack on some muscle in the gym, protein content is key. This product is a great pick for both protein and BCAAs.
Jacked Factory Authentic ISO
Authentic ISO is a solid protein powder for guys who have the goal of bulking up without doing a dirty bulk. Many other protein powders have extra calories from fats and carbs that you won’t need to worry about here. Authentic ISO provides a solid dose of 25 grams of protein per scoop to potentially help pack on muscle. This protein also has low amounts of carbs and fat with only a half gram of fat and one gram of carbs, making it great for men on a bulk who want to add lean muscle only. Each scoop only has 110 calories.
Dig into this easily digesting grass-fed whey isolate that provides 25 grams of protein with each lean 110 calorie scoop. It comes in three tasty flavors at a cost-effective price making it a solid choice for nearly anyone.
Since the protein source is a whey isolate, it may digest easier than other powders, which can help men who have digestive problems. Authentic ISO is available in three flavors — Vanilla, Chocolate Peanut Butter, and Vanilla Oatmeal Cookie. The price is tasty here too and cheaper than a lot of other high-quality proteins at about $39.99 per 30-serving container (approximately $1.33 per serving).
Who Should Buy Jacked Factory Authentic ISO
- Men looking for a whey isolate powder with a high protein content that may help with muscle gains without causing a ton of bloating like you might get from whey concentrates.
- Athletes who want a lean protein powder that doesn’t contain a ton of additional macros. This only has half a gram of fat and one gram of carbs.
- Anyone who is on a budget will appreciate that this is priced well, especially for the high quality of the protein included.
Who Shouldn’t Buy Jacked Factory Authentic ISO
- Folks who are lactose intolerant may want to find a plant-based formula. This is a whey isolate that has less lactose than concentrate, but may still contain more lactose than you would like.
- Anyone who is trying to avoid artificial ingredients and sweeteners may want to look elsewhere as this product contains sucralose.
- Those who prefer to buy their protein in bulk as this only comes in a 30-serving option.
For men who are trying to round out their diets and gain some muscle, Jacked Factory Authentic ISO is a great way to pack in 25g of protein and potentially leave bloating behind.
Best Whey for Weight Loss
Whey isolate protein powder is the go-to pick among people who are looking to lose weight and for good reason. It’s high in protein, but generally low in carbs, fats, and sugars, which means the calories are typically overall lower than other protein types. Our top pick for weight loss, Swolverine Whey Protein Isolate, is no different but also offers some additional benefits.
Disclaimer: Please note that none of these products describe themselves as weight loss supplements and should not be taken as such. Please consult with a medical professional before beginning any weight loss protocol.
Swolverine Whey Protein Isolate
Due to its profile of ingredients and macronutrient breakdown, Swolverine Whey Protein Isolate is our favorite protein for weight loss. It’s low in calories with just 110 calories per scoop, each providing 26 grams of protein. Other than that, it only contains half a gram of fat and a gram of carbs per serving, making it very lean. Even better, Swolverine uses natural sweeteners like stevia and monk fruit extract, so you don’t have to worry about artificial sweeteners here. You’ll also get a blend of minerals (like calcium and phosphorus) and electrolytes, which you may be lacking if you’re dieting.
This whey protein formula delivers 26 grams of protein with just 0.5 grams of fat, and one gram of carbs. You’ll also find 10mg of digestive enzymes, and a decent number of micronutrients.
One of the things that sets this blend apart from other wheys (and why isolates) on the market is its digestive enzyme blend. You’ll get 10mg per scoop, which is made up of five milligrams of papain (that can help break down proteins) and five milligrams of protease (that can help further break down the amino acids) for potentially more efficient digestion.
The last thing anyone wants while dieting is to feel bloated and these digestive enzymes are intended to help in that regard. At about $2.10 per serving, you’ll also have four tasty flavors to choose from — Chocolate, Vanilla, Honey Cinnamon Peanut Butter, or Mint Chocolate Chip.
Who Should Buy Swolverine Whey Protein Isolate
- Anyone trying to lose weight who may want a protein powder lower in calories — this one only has 110 per serving.
- People who have trouble digesting even more refined protein powders like whey isolates will like the inclusion of digestive enzymes here, which can help with that process.
- Athletes who prefer not to have artificial sweeteners in their protein powders. Swolverine sweetens this whey isolate with all-natural stevia and monk fruit extract.
Who Shouldn’t Buy Swolverine Whey Protein Isolate
- Customers who want a protein powder with more carbs, fats, and calories to supplement their diet — this one is low in all three.
- Folks who prefer the stronger flavors you can get from artificial ingredients. Naturally, sweetened proteins can sometimes lack sweetness.
- Those who are on a tight budget may want to look at more cost-effective options.
Caloric intake largely dictates whether you’ll gain or lose weight, but this protein powder may help to curb your appetite, making you less likely to indulge in higher-calorie foods. If your goal is to lose some weight while maintaining muscle mass, a lean protein shake like this one from Swolverine may be just what you’ve been looking for.

Best Whey Protein for Muscle Gain
It’s no secret that protein can play a key role in muscle gains. This pick is a whey protein isolate, which means it has a high protein content and is also one of the highest doses of protein on this list.
Transparent Labs Whey Protein Powder
Sourced from 100 percent grass-fed American cows, Transparent Labs Grass-Fed Whey Isolate packs 28 grams of protein into each scoop. Many other powders only have around 20g to 25g of protein per scoop. At 88 percent protein-by-weight, it also has one of the highest protein-by-weight ratios on this list.
With 8 different flavors and 28 grams of whey protein from hormone-free, grass-fed cows, Transparent Labs Whey Protein Isolate is an excellent way to hit your protein macros.
Clean of artificial sweeteners, food dyes, gluten, and preservatives, this whey isolate also contains only half a gram of fat, a single gram of carbs, and no added sugars. It comes in seven flavors, and you can buy up to three tubs at once for a discounted rate. If you buy at regular price, this protein is a bit on the pricey side at around $59.99 for a 30-serving container (about $2.00 per serving) — but the natural and transparent ingredients list may make it worth the extra money for some people.
Who Should Buy Transparent Labs Whey Protein Powder
- Bodybuilders looking to pack on muscle. This isolated whey ensures you’re getting just protein and essentially no other macros. It’s the equivalent of eating a four-ounce chicken breast, except it’s more convenient for when you’re in a pinch.
- Customers who are wary of artificial sweeteners, dyes, and preservatives — this pick is free of all three.
- Anyone who wants a variety of flavors to choose from will like that this product comes in seven flavors.
- Folks who are looking to buy their protein powder in bulk — you can buy up to three tubs at once for a discounted rate.
Who Shouldn’t Buy Transparent Labs Whey Protein Powder
- Athletes who want a higher calorie or carb content to potentially help pack on more weight, or for more energy during tough training sessions.
- If you’re not concerned with protein-by-weight, there are less expensive whey concentrates you can buy instead to save some cash.
Whey protein isolate is one of the best options to potentially help with muscle gain because of its high protein content — just be aware that you may have to dish out a little extra money for it.
Best Tasting Whey Protein
Sometimes all you’re looking for in a protein supplement is a great taste that will keep you hooked for a while. This pick comes in six yummy and different flavors for you to try out.
Huge Supplements Huge Whey
Aside from being solid on macros, this pick has six downright delicious flavors to choose from, though it may be difficult to select only one. Of course, there are the classics like Vanilla Milkshake, Cookies & Cream, and Chocolate Peanut Butter, which will appeal to the masses. But Huge makes some unique flavors too, like Fruity Cereal, Blueberry Muffin, and our favorite, Strawberry Cheesecake.
A blend of whey isolate and whey concentrate, Huge Supplements Whey Protein packs 23 grams of protein into each serving. It also contains 5g of BCAAs with only 2g of fat and 2.5g of carbs per serving.
Huge does use whey concentrate to provide a nice dose of 23 grams of protein per serving — though people who have trouble digesting lactose may find some indigestion from the concentrate. You’ll also receive two grams of fat and two and a half grams of carbs for a total of 120 calories per scoop. Five grams of BCAAs in each serving is the cherry on top. In terms of price, this pick is a bit on the pricey side for a whey concentrate, but the flavors choices, and taste make it worth it in our eyes. Pick up a 30-serving container for around $49.95 (about $1.67 per serving).
Who Should Buy Huge Supplements Huge Whey
- People who value flavor and taste. Huge made sure to make different flavors that you won’t easily find elsewhere, like Blueberry Muffin and Strawberry Cheesecake.
- Folks who are looking to slim down will like that this has a rather lean formula with few extra macros and only 120 calories.
- Anyone who likes BCAAs to be included in their protein will receive five grams per serving from Huge Whey.
Who Shouldn’t Buy Huge Supplements Huge Whey
- Anyone looking for a budget protein powder — though not the most expensive on the list, Huge Whey is on the pricey side for a whey concentrate.
- People who are looking for the most protein they can have per serving can find powders with more protein per scoop.
- Those who are lactose intolerant will want to look for a plant-based protein or a hydrolyzed whey.
With six special flavors to choose from and 23 grams of protein Huge Whey is sure to have something that delights both your taste buds and your muscles. Just don’t be mad at us if you become hooked on the stuff.
Best Grass Fed Whey Protein
If you’re on the hunt for a protein that’s derived from 100 percent grass-fed whey, this pick has you covered with 26 grams of grass-fed whey per scoop.
Swolverine Whey Protein Isolate
If you prefer to source your protein from grass-fed cows you’ll likely enjoy Swolverine Whey Isolate since their protein is, as Swolverine says, “sourced from the happiest grass-fed cows in America.” Each scoop packs in 26 grams of high-quality whey isolate, along with a half gram of fat and only one gram of carbs for a total energy content of 110 calories. To help potentially improve digestion Swolverine also includes a 10mg digestive enzyme blend of papain and protease, along with electrolytes and calcium.
This whey protein formula delivers 26 grams of protein with just 0.5 grams of fat, and one gram of carbs. You’ll also find 10mg of digestive enzymes, and a decent number of micronutrients.
You can pick up this protein powder in tried and true flavors like Vanilla and Chocolate, or branch out a bit and try more interesting flavors like Honey Cinnamon Peanut Butter or Mint Chocolate Chip. The high quality of this protein makes it a bit more expensive than some others at around $62.99 for a 30-serving tub, which is about $2.10 per serving.
Who Should Buy Swolverine Whey Protein Isolate
- Athletes who prefer a whey isolate protein that comes from 100 percent grass-fed cows. Swolverine even says their cows are happy.
- If you’re looking for some multivitamins in your protein powder, this blend may help balance out your nutrient intake.
- Folks who have trouble digesting protein powder may find relief in this formula thanks to the added digestive enzymes.
Who Shouldn’t Buy Swolverine Whey Protein Isolate
- Those who want a higher dose of carbs, fats, or sugars in their protein powder — this powder is rather lean.
- Vegans who want a powder that isn’t derived from animal products will want to look for a vegan-friendly protein powder.
- This is one of our more expensive picks at $2.10 per serving, so you may want to look elsewhere for those on a budget.
Swolverine sets themselves apart from the rest of the whey isolate market with their 100-percent grass-fed whey and potentially game-changing digestive enzyme blend. The macros are also desirable with 26 grams of protein and little in the way of extra calories.
Best Organic Whey Protein
If you focus a lot on the ingredients you put into your body, you may want a protein powder that uses all organic ingredients that you can pronounce. This pick has a blend of vegetables to provide the protein and is naturally flavored and sweetened to give you peace of mind.
KOS Organic Plant Protein
Right off the bat you’ll notice that this isn’t your typical “brotein” powder. KOS acquired all the ingredients from natural and organic sources to build a clean, naturally flavored vegan protein powder. To provide 20 grams of protein per scoop, they used organic pea protein and coconut milk along with flax seed and quinoa, making this a complete protein. This formula does contain five grams of fat and eight grams of carbs for a total of 150 calories per scoop, which may be a bit high for people who are strictly counting macros.
This protein powder packs 20 grams of plant-based protein plus various superfoods, vitamins, and minerals. It also contains enzymes to aid digestion and promote gut health.
KOS Organic Plant Protein is a different kind of protein product with a blend of organic plants like peas, coconut, flax, and quinoa providing 20 grams of protein per scoop. Their light and sweet flavorings are made from natural ingredients and coconut sugar.
The flavors — Chocolate and Vanilla — are meant to be light, refreshing, and tastefully sweetened using natural flavorings and sweeteners, like coconut sugar, stevia extract, monk fruit, and Peruvian cacao. You might expect to pay quite a premium for these high-quality ingredients, but each 30-serving tub is only about $49.99 (around $1.67 per serving), which is in line with many top-notch dairy protein powders. As an added bonus, you’ll receive a blend of 17 vitamins and minerals in each scoop, including vitamin E, zinc, chromium , and B vitamins.
Who Should Buy KOS Organic Plant Protein
- People who care about the ingredient list in their protein. This is an all-natural powder made from organic ingredients.
- Those who want some vitamins and minerals with their protein will like the blend of 17 micronutrients included in each scoop.
- Folks who have trouble digesting dairy-based protein or those who want a vegan protein source. This is all plant-based protein.
Who Shouldn’t Buy KOS Organic Plant Protein
- Anyone who doesn’t care to eat all organic or plant-based may be able to find better alternatives for their wants and needs.
- Lifters who are looking to slim down may want a protein that contains fewer carbs and fats to assist your cut.
- People who don’t like the taste of stevia may want to look elsewhere for their protein needs.
KOS did what they do best here, and put together an organic plant-based formula that serves. Each scoop provides a solid dose of 20 grams of protein along with a variety of micronutrients to potentially fill gaps in nutrition with clean ingredients.

Best Whey Protein Isolate
Whey isolate is a form of whey protein that has been filtered to reduce its lactose and fat content, leaving around 90 percent protein content behind. This type of whey (and this pick in particular) packs a larger amount of protein per serving than many other forms and tends to be more easily digested.
Transparent Labs Whey Protein Powder
Most whey protein isolates offer a solid dose of protein with reduced lactose content but Transparent Labs stands out for what it doesn’t contain as much as for what it does. Fats are nowhere to be found here with zero grams in each serving and only one gram of carbs, meaning that the 120 calories per scoop nearly all come from the large 28-gram hit of protein in each serving.
With 8 different flavors and 28 grams of whey protein from hormone-free, grass-fed cows, Transparent Labs Whey Protein Isolate is an excellent way to hit your protein macros.
Other highlights include an all-natural formula with no artificial sweeteners, as Transparent Labs uses stevia in their blend, and the whey sourced from 100-percent grass-fed cows. Transparent Labs makes this whey isolate in eight different flavors with options like Cinnamon French Toast, Mocha, and Oatmeal Chocolate Chip Cookie, among other classics. You can snag a 30-serving tub for around $59.99 (about $2.00 per serving), which is somewhat pricey, but we think it’s worth it when considering the high quality of ingredients and potentially easier to digest formula.
Who Should Buy Transparent Labs Whey Protein Powder
- Folks who want to add more protein to their diet without adding a bunch of extra calories will like that this blend packs 28g of protein and only 110 calories per scoop.
- Anyone who has trouble with bloating or digesting protein powders will appreciate the whey isolate formula, which may digest more easily than other protein types.
- Athletes who want to stay away from artificial sweeteners. This powder is sweetened with stevia and natural flavors.
Who Shouldn’t Buy Transparent Labs Whey Protein Powder
- Budget-conscious shoppers. Isolate formulas are generally more expensive than concentrates, and this protein is no different at about $2.00 per serving.
- People who are looking to bulk up or who need a meal replacement should look at other options since this is a rather low-calorie protein supplement.
- Anyone who’s looking for a bulk-buy option may be disappointed that this only comes in 30-serving containers.
This powder’s no-fat, low-carb formula delivers a high dose of protein with minimal extra calories. On top of that, it can potentially digest more easily than whey concentrate and features an all-natural ingredients list. If you want to sneak extra protein in your diet, and forgo the extra calories and potential bloating, this product may be the way to go.
Best Whey Protein Meal Replacement
If you want a whey protein with solid macros and plenty of additional micronutrients to help nourish you, this product is going to be a great fit.
Transparent Labs MRP
Whey protein is great for folks who just want protein and nothing else, but it’s not the most nutritious option. If you’re on the hunt for a protein that offers more carbs and fats for muscle recovery, or a formula that can replace a standard meal, then this pick is your best bet.
Transparent Labs MRP provides 19g of slow-digesting carbs, 24g of protein, and only 7g of both sugar and fat. It also contains MCT oil and bone broth, which can help with gut health, and boasts a moderate 220 calories per serving.
Each one-scoop serving delivers 220 calories, seven grams of fat, 19g of carbs, and five grams of fiber. Plus, it also contains a dose of calcium, iron, sodium, and potassium for an added nutritional boost. However, this is one of the more expensive options on this list at around $2.00 per serving, since you are technically getting a more substantial meal out of each serving than a basic whey protein powder provides.
Who Should Buy Transparent Labs MRP
- Anyone who wants a protein powder that can replace an entire meal.
- Athletes who need more calories and carbs overall to help recover from tough workouts.
- If you’re always on the go and need an easy-to-consume meal to take with you, this meal replacement can help.
Who Shouldn’t Buy Transparent Labs MRP
- People who use protein purely as a supplement and prefer to eat their carbs and fats.
- Anyone who doesn’t want to drink their calories will want to look for a protein bar.
- Lifters on a cut. Meal replacement drinks, though filling, aren’t as satisfying as regular foods.
You want your meal replacement powder to maintain a balanced macro profile that simply scales along with the calorie count. Transparent Labs MRP does this, and, better yet, it also contains a good amount of micronutrients to fill in some dietary gaps.
Best Sustainably-Sourced Whey Protein
Onnit contains effective and transparently sourced ingredients, is made from grass-fed cows, and delivers on taste.
Onnit Whey Protein
Onnit contains zero sugar, is soy- and gluten-free, and is made of 100 percent grass-fed whey protein isolate from pasture-grazing New Zealand cows. It also contains minimal carbs and fats — just five and two grams, respectively. We like that Onnit mixes well in water and milk, and comes in delicious Mexican Chocolate or Vanilla flavors with a price tag of about $2.00 per serving.
A grass-fed whey isolate includes added ingredients for digestion like seven digestive enzymes and a probiotic (lactobacillus acidophilus). It's also gluten-free, sugar-free, and soy-free.
Plus, it contains digestive enzymes, which can help your body process the nutrients you’re receiving even better. However, if you want to avoid maltodextrin or sunflower oil, then look elsewhere; this protein powder contains both of those ingredients. This protein will cost you about $2.00 per serving, but as New Zealand is notably strict on its dairy policies, you can rest assured knowing your protein is sourced from high-quality dairy.
Who Should Buy Onnit Whey Protein
- People who want a grass-fed whey isolate protein without sacrificing flavor — this powder is extra creamy due to its grass-fed base.
- Athletes who want digestive enzymes that can help them process their protein powder better.
- People who care about the welfare of the animals that provide their protein — this protein isolate comes from New Zealand cows that graze freely in pastures.
Who Shouldn’t Buy Onnit Whey Protein
- People who want to avoid maltodextrin at all costs. This is a common additive in many whey proteins to help with flavor, and Onnit does contain some.
- If you’re avoiding seed oils, you may want to look elsewhere. Onnit contains sunflower oil to help with flavor.
For people who are environmentally minded, Onnit ensures that their whey is sourced sustainably from New Zealand cows. The sourcing matters, as New Zealand has strict regulations regarding their dairy industry, which guarantees a high-quality product.
Read our full review of Onnit Whey Protein.
Best Vegan Non-Whey Protein
Whey protein is the industry standard for protein supplementation, but whey also isn’t vegan-friendly as it’s a byproduct of making dairy products, like milk and cheese. Others may want to avoid whey due to potential spoilage (though this is rare if the right storage conditions are met), or unappealing smells or tastes.
Swolverine Plant Protein
Swolverine’s plant-based protein is made from 22 grams of pea protein isolate and 7.7 grams of pumpkin protein. Compared to other protein powders for vegan diets, Swolverine Plant Protein is pretty low in fats and carbs, boasting only 0.5 and seven grams, respectively.
This plant-based protein is made from pea isolate, hemp protein, pumpkin seed protein, sacha inchi, and quinoa. It's also pretty low in fats and carbs, boasting only 0.5 and seven grams, respectively.
While the carbs are a tad high compared to whey protein isolate formulas, they’re pretty low for a plant-based powder. It’s worth noting that this product only comes in a Chocolate Cake flavor and a Salted Caramel flavor though — while many of us do love a decadent chocolatey treat or a Salted Caramel taste, those who prefer a Vanilla or fruity flavor will have to look elsewhere.
Who Should Buy Swolverine Plant Protein
- Plant-based eaters who want a vegan formula as this product is made with a blend of plant-based proteins, like pea and pumpkin.
- Anyone who wants a vegan protein that closely resembles the macronutrient makeup of a whey protein powder.
- If you like knowing everything that goes into your protein powder, you’ll like this product’s transparent ingredient label.
Who Shouldn’t Buy Swolverine Plant Protein
- Anyone who wants a whey formula — this formula is made from plant-based protein.
- Folks who don’t like Chocolate or Caramel flavors will want to look elsewhere as this product only comes in Chocolate Cake and Salted Caramel.
- People who want an inexpensive protein powder can find much cheaper options on the market.
It’s not uncommon for plant-based proteins to be higher in carbs and fats (due to the source ingredients), but Swolverine’s macro profile is as close to whey as any plant-based protein we’ve seen.
Best Whey Protein for Bulking
The best whey protein for bulking is this no-nonsense formula from Huge Supplements. It has a solid dose of protein and some great flavors, allowing you to bulk up without having to chew through yet another chicken breast.
Huge Supplements Huge Whey
If you’re looking to bulk up and maybe can’t stomach another bite of food with your current macros, then you’ll appreciate the 23g of protein per scoop that Huge Whey delivers. Each scoop also has two grams of fat and two and a half grams of carbs for 120 calories total. In addition to the protein provided, each scoop serves up five grams of BCAAs, which may help to pack on muscle and jumpstart muscle protein synthesis.
A blend of whey isolate and whey concentrate, Huge Supplements Whey Protein packs 23 grams of protein into each serving. It also contains 5g of BCAAs with only 2g of fat and 2.5g of carbs per serving.
It may not be the most calorically-dense protein out there, but the great tasting and varied flavors make this great for bulking since you’ll actually enjoy drinking it and look forward to trying new options. Enjoy downing your protein shake with flavors like Blueberry Muffin, Strawberry Cheesecake, Fruity Cereal, and classics like Vanilla Milkshake or Cookies & Cream. Pick up a 30-serving container for the reasonable price of around $49.95 (about $1.67 per serving).
Who Should Buy Huge Supplements Huge Whey
- People who want added BCAAs in their protein to potentially aid in muscle building during a bulk.
- Folks who have trouble eating enough protein when bulking may find it easier to down a shake rather than solid food.
- Anyone who is looking for a good-tasting protein will appreciate the wide range of flavors here.
Who Shouldn’t Buy Huge Supplements Huge Whey
- Those who are looking for a protein powder that is higher in carbs or fats will want to look elsewhere.
- Penny pinchers will find that this product is pricier than conventional whey concentrate.
- If you’re looking for the highest protein per serving then there are other options with higher protein content on this list.
This whey protein is high in protein and flavor, making it an easy ask to drink often, especially if you’re downing multiple shakes per day during a bulk. The added BCAAs are also a nice touch that may help pack on muscle even more than a traditional whey powder would.
Best Whey Protein for Women
Though this protein powder isn’t marketed specifically toward women, it’s a great choice for anyone hunting for a powder that’s low in fat, carbs, and sugars, but high in protein.
Legion Whey Isolate Protein Powder
At just 100 to 130 calories per serving (depending on flavor), Legion Whey Isolate packs 22 grams of whey protein isolate into each scoop. It contains only one and a half grams of fat (or less, depending on flavor), two to four grams of carbs, and zero grams of sugar.
An all natural, non-GMO, fat-free whey that's cheaper than many competitors, Legion Whey Isolate Protein Powder is made from 100 percent grass-fed whey protein isolate from sustainable dairy farms in Ireland. It's also higher in calcium compared to other powders on the market.
This formula is ideal for women who may be looking for a leaner blend. It’s also naturally flavored and sweetened, so if you’re trying to stay away from artificial ingredients, this is a great pick for you. Another added bonus: This whey isolate comes in 13 different flavors, as well as an unflavored option. You have the choice of buying a two-pound tub, or if you know what flavor you like, you can opt for a bulk buy five-pound tub.
Who Should Buy Legion Whey Isolate Protein Powder
- Women who are looking for a lower-calorie whey protein with very few carbs, fats, and sugars will appreciate the macros in this formula.
- Customers who are interested in more unique flavors will like that there are 13 options to choose from here.
- If you don’t want to consume any artificial sweeteners or flavors in your whey protein, this pick is for you.
Who Shouldn’t Buy Legion Whey Isolate Protein Powder
- Folks who are trying to bulk up may want a higher-calorie protein supplement that contains more carbs.
- Athletes who are interested in a blend of proteins or a whey concentrate; this pick is pure whey isolate.
Though this supplement is a solid choice for anyone looking for a whey protein isolate, it’s marketed specifically to women. It’s lower in calories, fat, sugar, and carbs than many whey proteins, and it comes in a wide variety of flavors.

Best Hydrolyzed Whey Protein
When it comes down to it, most proteins will offer just about the same muscle-building benefits. That said, price is a significant factor for many folks, and we think that Dymatize offers one of the best quality hydrolyzed proteins at a competitive price.
Dymatize ISO 100
Why Dymatize? Besides the fact that it tastes great with water — some may find it too sweet — the first ingredient in the product is hydrolyzed whey protein. We dive deeper into the science further down in this article, but the long and short of it is that hydrolyzed whey absorbs faster than other forms of whey.
Dymatize ISO 100's hydrolyzed whey absorbs faster than other forms of whey as enzymes partly break it down. Plus, this product is sweet and tastes great mixed with water.
That’s because enzymes partly break it down, and this fast absorption is what makes it more expensive. However, Dymatize ISO 100 offers one of the best price points for hydrolyzed whey that you will find. On a positive note, Dymatize offers nine flavors including Chocolate Peanut Butter, Cookies & Cream, Gourmet Chocolate, Gourmet Vanilla, Pebbles™ Birthday Cake, Cocoa Pebbles™, Fruity Pebbles™, Dunkin™ Mocha Latte, and Dunkin™ Cappuccino.
Who Should Buy Dymatize ISO 100
- People who like mixing whey with water; this powder tastes great without adding milk or any other ingredients to the shake.
- Low-fat dieters; there’s no fat at all in most of Dymatize’s flavors.
- Anyone who’s interested in an easy-to-absorb whey protein — hydrolyzed whey is typically your best bet.
Who Shouldn’t Buy Dymatize ISO 100
- People who are looking for all of their whey to be hydrolyzed; while it’s the first ingredient, there’s also some regular whey isolate in there.
- Folks without a sweet tooth; this product is really quite sweet. That’s why it’s great with water.
If you’re a serious lifter who desires the low-fat, low-carb formula that hydrolyzed whey offers but can’t deal with the sticker shock, then this is the pick for you.

The Benefits of Whey Protein Powder
Protein powders usually offer a higher protein concentration than food, but they may also lack other nutrients that naturally accompany proteins found in meat, fish, dairy, and whole grains. Protein from food offers vitamins, minerals, carbohydrates, and healthy fats often unavailable in protein powder. We would never recommend that you take protein powder as a complete protein substitute — just a dietary supplement.
There’s plenty of debate among bodybuilders and strength athletes alike about whether a post-workout shake significantly improves recovery and muscle growth.
Some research suggests that taking a protein shake after you work out might be better for muscle gain than whole foods. A study published in Physiological Reports suggests that taking 40 grams of whey protein is better than 20 grams, so maybe you should have two protein shakes. (1) Another study suggests pre-workout protein is even more important. (2) As for the type of protein you should consume, does it have to be whey? Brian St. Pierre, MS, RD, at Precision Nutrition told us:
“Whey protein has an incredibly high biological value, incredibly high leucine content, and it’s digested rapidly so you get this quick rise in muscle protein synthesis. And if you look at short-term studies, two hours after a workout you see this rapid rise in protein synthesis with whey more so than soy.”
Leucine is linked with muscle protein synthesis, and whey is super high in leucine, according to a 2012 protein comparison published in Nutrition & Metabolism. (3)(4)
If you’re regularly engaging in strenuous exercise, you need to calculate your macros and consume a relatively large amount of protein (and calories overall) to build muscle, recover properly, and get stronger for the next workout. Whey is a fantastic way to help with that.

How We Chose the Best Whey Protein
It may look uncomplicated, but assessing the key differences between different protein powders is no easy task. It’s important to emphasize that some of the areas we note below aren’t necessarily good or bad. Some athletes prefer foods without artificial sweeteners, and some try to limit soy. That said, there’s not much evidence that either has adverse effects; we simply point them out in case they are a problem for you. Here are the ingredients and factors we took into consideration when putting together this guide.
Types of Protein Powders
Whey proteins typically contain one or more of three kinds of protein: concentrate, isolate, and/or hydrolysate. They each have their own pros and cons: Whey concentrate is cheaper and extracted with an enzyme or acid; whey isolate is lower in fat and carbs; hydrolyzed whey digests more quickly and could be safer for those with allergies. All of this is taken into account, and we’ve included all types of whey on this list — no matter your preference, there’s an option for you here.
Protein Per Calorie
A gram of protein has four calories, and many measure the protein density of a supplement by how many calories it provides per gram. If a shake offers 25 grams of protein, then you’re getting 100 calories (if there aren’t any added carbs and fat.) To keep calories lower, you typically want a protein powder with fewer grams of carbs and fats. So, pay attention to this number.
Artificial Sweeteners
We’re not taking a stance on whether artificial sweeteners are unhealthy, but we can’t ignore that many athletes prefer to avoid them. To that end, we’ll point out the presence of aspartame, sucralose, acesulfame potassium, and anything else used to sweeten the product, like stevia or sugar alcohols, which can cause digestive issues among a small portion of the population.

Protein Powder Additives
Some people avoid soy at all costs, but soy is a trendy addition to protein supplements as a means to improve mixability. Perhaps you have issues with thickeners and stabilizers like xanthan gum or carrageenan, which can cause digestive discomfort. Again this is about your preference, but we take these ingredients into account.
Protein Powder Taste
Chalky, smooth, sweet, earthy, bitter…there are many ways a protein powder can taste. We consider the real taste test to be how a protein powder tastes with water — it’s not as hard to make something that tastes good with milk.
What’s In Your Protein Powder?
Aside from protein, there can be a range of added nutrients included in your protein powder. Here’s a guide to the most common ingredients you’re likely to find in a tub.
Whey Concentrate, Isolate, or Hydrolysate
Usually a byproduct of cheesemaking, whey concentrate is the cheapest form of protein and contains the most fat and carbs, including lactose. Whey isolate has been processed through a microfilter and results in fewer carbs and less fat, sometimes none at all.
In contrast, hydrolysate (aka hydrolyzed whey) has been further broken down with enzymes, so it digests the fastest.
Casein
Sometimes included with whey protein powders, casein is the other protein found in milk. (Milk protein is about 80 percent casein, 20 percent whey.) Used to make cheese — it’s not a byproduct of cheesemaking, it is the product — casein digests more slowly and is more filling. It also thickens really easily, so it’s great for making protein puddings and “ice cream.”
Artificial and Natural Sweeteners
Protein powders often contain either artificial sweeteners like sucralose or acesulfame potassium, as they’re widely recognized as safe for human consumption.
The FDA recommends a daily limit of 15 milligrams of artificial sweeteners. Some of the protein powders we’ve included on this list contain no artificial sweeteners though. These products are sweetened naturally with ingredients like Stevia.

Lecithin
This is a fatty substance used to improve mixability. Lecithin is usually made from soy, but sometimes you’ll find the more expensive sunflower lecithin in products that are more geared toward the soy-phobic Paleo crowd. There’s no good reason to fear soy lecithin unless you have an allergy or sensitivity — reams of research have found no correlation between soy ingestion and reduced testosterone or muscle mass. (5)(6)
Digestive Enzymes
Digestive Enzymes may help break down proteins, lipase fat, amylase carbs, and lactase lactose, and many protein powders include a blend of these enzymes (which may include Protease, Lipase, or Amylase).
Some interesting evidence suggests they might help to increase the absorption rate and reduce the risk of indigestion. (7)
When To Take Whey Protein Powder
There isn’t necessarily a “best time” to take your protein powder. Just because you don’t consume your shake directly after your workout does not mean you’ll lose the muscle you worked so hard for throughout your session. As long as you are consuming enough protein throughout the course of the day, your gains should remain.
If you can get a shake in immediately after a workout, that’s a great way to ensure you’re boosting your overall protein intake, but it’s not a requirement to keep you on track to hit your goals.
You Don’t Have to Take Protein Before, During, or After a Workout
There are many nutrition myths perpetuated by 1990s bodybuilding magazines — one of them is that you need to down a protein shake minutes after your workout to feed your starving muscles. While that might not be a bad idea for an Olympia competitor who already has all of their calories, macros, micros, sleep, hormone levels, and everything else dialed in, it doesn’t matter for the average person. Your total calories and macronutrients determine whether or not you gain muscle and lose fat, not when you eat.
How Much Does Whey Protein Powder Cost?
If you just look at the cost of the container of whey protein that you’re buying, it’s going to be hard to tell what you’re actually getting for your money. To find out how much whey protein you’re actually getting for your money, you’ll want to compare the cost of the container to the number of servings — you’ll likely find the cost per serving to be around $1 to $2, varying by brand and ingredients. The average price of whey protein on this list is $1.78 per serving. Of course, there are some exceptions to this price range and you’ll notice a higher price based on the quality of ingredients, dosages, and type of protein.

Cost is affected by the type of whey powder, additives, protein density, and other factors. The more natural, organic, or transparent your protein powder is, the more likely it is that the cost will be higher. In addition, added helpful ingredients (like digestive enzymes or probiotics), may also jack up the price tag. You’ll find that the most basic protein powders (some of which may include artificial flavorings) will generally be the least expensive.
What to Consider Before You Buy Whey Protein Powder
Protein powder is just dehydrated milk with some sweeteners, but it’s easy to get overwhelmed by the process of buying a whey protein powder. Here are the most important things to keep in mind when purchasing a new protein powder.
Whey Concentrate Might Not Be Great for Those With Lactose Sensitivities
It’s the cheapest form and has the most calories, but whey concentrate isn’t bad: The difference is usually two or three grams of protein when compared to isolate. But concentrate does contain lactose. It’s not a lot but consider buying a hydrolyzed whey — which is typically easier on the stomach — if you’re really sensitive.

Hydrolyzed Whey Is Best for the Elite Few
It’s the most expensive form of whey, and yes, some studies have found it useful for athletes who work out twice per day and need to recover really fast. However, for the average person, it won’t make a practical difference. A caveat here is that hydrolyzed whey is so broken down that it’s usually the whey of choice for people with milk allergies. (8)
(If you have a milk allergy or any food allergy for that matter, consult with your doctor before taking a protein powder.) The downsides of hydrolyzed whey — that it’s more expensive and tastes worse — probably make the added cost not worth it for most people.
You Probably Don’t Need to Worry About Soy Lecithin
The vast majority of protein powders contain a dash of soy lecithin because it helps to improve mixability. Concerns over soy raising estrogen levels or lowering testosterone levels have been floating around the strength training world for years, but studies show that most people’s hormone levels are unaffected by soy. If you want to learn more about the effects of soy, check out our video below where we dive deeper into the studies surrounding this topic.
And note that if you’d rather avoid plant estrogen, you’ll also need to cut out coffee, oatmeal, apples, and a lot of other foods, too.
Grass-Fed Whey Probably Won’t Have a Practical Difference On Your Health
Grass-fed dairy is indeed higher in antioxidants and healthful fats, like Omega-3s and CLA, than regular dairy. (9)(10) That said, whey has almost all of the fat taken out of it anyways. For context, people supplement with one or two grams of omega-3s when consciously trying to consume more. Whey has about three grams of fat, and less than five percent are polyunsaturated fats. And even less of that fat is omega-3s. (11)
The same dosage goes for CLA, of which you’d find 0.06 grams in a scoop of grass-fed whey. (10) Grass-fed cows probably live happier lives with more time spent outdoors, which is a valid reason to prefer it. But don’t think taking grass-fed whey over regular whey is like taking a multivitamin. (12)

Final Word
There are a variety of protein types on the market, and each has its own advantages and drawbacks. We tried to pick the best for as many scenarios as we could because we know everyone is different and has different goals. Finding the right protein that interacts properly with your gut microbiota and that you actually enjoy taking can take some trial and error — that’s why we laid out a few options that could work for different situations.
It wasn’t easy to land on these top picks; we had to weigh ingredients, effectiveness, taste, and many other factors, including how different consumers value totally different qualities in their supplements. But we’re confident that we’ve selected the best whey protein powders no matter what your reasons are for turning to protein shakes. Each of the picks on this list is of the highest quality, so no matter which one you choose you’ll be getting a top-tier product. All we can say now is bottoms up.
FAQs
What is whey protein powder?
There are two types of protein in milk: whey and casein. The two get separated in the cheesemaking process, and while whey used to be considered something of a waste byproduct, it’s a very high quality protein that can be processed into powder. Usually, flavorings are added to make for a convenient and relatively inexpensive way to consume protein.
How much does whey protein powder cost?
Whey protein ranges in its pricing, but we found most of the protein powders on our list cost between $1.00 and $2.00 per serving with an average cost of $1.78 per serving. Although there are many factors that will affect the price of protein powder, such as ingredient list, type of protein, and formulation, you can expect to pay around that price per serving across the board. Whey isolates tend to run a bit more expensive, so if you aren’t tied to an isolate you may save a bit of pocket change by opting for a whey concentrate.
What's the difference between whey concentrate vs isolate?
Whey concentrate is the least processed kind of whey protein powder, so it has the most carbohydrates and fat. (About three grams each per 20-25 grams of protein.) Whey isolate is further processed in a way that reduces most of the carbs and fat. Some whey isolates contain no carbs or fat whatsoever. This makes it more diets that severely restrict carbohydrates and/or fat, though the taste does suffer somewhat.
What is the best whey protein powder?
There are so many amazing protein supplements on the market, but after testing several types of protein, we think Transparent Labs Whey Protein Powder is the best overall whey protein powder. The macro split of 28g of protein, no fat, and only one gram of carbs makes it a top choice for getting a solid dose of protein while keeping other macros low. It contains whey isolate, which may digest more quickly and prevent bloating, and comes in eight delicious flavors, too.
