  • Protein per serving: 28 grams
  • Flavor options: 18 flavors available
  • Who it’s for: Folks looking for a protein powder with a low lactose content

Pros

  • Whey is grass-fed and sourced in the USA
  • 14 flavor options

Cons

  • Pricier than other powders on our list
  • Contains some dairy, though it is a low amount
  • Not for those looking to avoid stevia

Our Thoughts on Transparent Labs 100% Grass-Fed Whey Protein Isolate 

Transparent Labs’ 100% Grass-Fed Whey Protein Isolate comes in 18 flavors, and is available in a two-pound or four-pound size. It’s gluten free, non-GMO, and contains no artificial sweeteners, coloring, or preservatives. This protein powder is also both Informed Choice and Informed Protein certified, meaning that it’s third-party certified for accuracy, purity, and banned substance testing.  

What We Liked

Kayla was our tester for this protein powder, rating it a 5 out of 5 for her first impression. At first glance, she noted that the packaging for Transparent Labs’ whey protein isolate is simple, clean, and gives you all the information you need to know without making it overwhelming. “The brand exudes transparency (hence the name) and shows that with their packaging, third-party testing, clean ingredients, and so forth,” she said. 

Transparent Labs Whey as best protein powder

Our tester found the instructions clear and easy to read, too. She followed the directions and said that after shaking it for 60 seconds, the result was super smooth and not grainy. “The mix has a small foam layer at the top, however, it wasn’t super thick,” Kayla noted. “I used 8 ounces of water and this seemed to be a good consistency. I think anything over 10 [ounces] would be too watery.” She rated the whey protein isolate a 5 out of 5 for mixing well.  

Kayla likes to prioritize flavor along with protein to calorie ratio. “With this product having 28 grams of protein and only 130 calories, you might start to worry that it’s going to lack in taste. This brand leaves you with zero disappointment.” She described it as having a slight sweetness that is not overwhelming, and a frothy, slightly fully body texture to it, something like a milky consistency, rating it a 5 out of 5 for taste, and a 3 out of 5 for sweetness.  

She also shared that she felt great after testing this protein powder. “Usually, whey protein isn’t a problem for me, but if it’s too thick I can feel full and sluggish. With this mixture, I felt great, and didn’t have any tummy issues that I sometimes do with plant or casein products.”  

What Could Be Improved

It’s hard to find something we want improved with Transparent Labs products. However, Transparent Labs’ protein isn’t the most budget-friendly on the market. This product is about $1.99 per serving, whereas some other options can cost as low as $1.50.

This product is also sweetened with stevia. This isn’t necessarily a negative thing, however, stevia may not work for everyone.

Specs

  • Protein per serving: 28 g
  • Calories per serving: 130
  • Third-party verification: Informed Choice
  • Cost per serving: $1.99
  • Servings per container: 30

  • Our thoughts: Our tested enjoyed the French Vanilla flavor, it wasn’t too sweet and the vanilla flavor was excellent
  • Protein per serving: 22 grams
  • Flavor options: Over 20 flavors available, including Pumpkin Pie and Chocolate Hazelnut
  • Who it’s for: Folks avoiding lactose

Pros

  • Lactose free

Cons

  • More expensive than similar protein powders
  • Clumpy, doesn’t mix easily
  • Made in facilities that may also process allergens like eggs, nuts, or wheat

Our Thoughts on Legion Whey+ Certified Grass-Fed Irish Whey Protein Isolate

Legion Whey+ is made with Truly Grass Fed™ certified whey isolate, sourced from small dairy farms in Ireland. The certification assures that cows are pasture-raised and fed a 95% grass diet for over 250 days each year. This protein powder is also tested in an ISO 17025-accredited third-party lab and is independently certified by Labdoor to contain no contaminants or banned substances. Alongside the transparent label, our tester absolutely loved the flavor of this protein powder. 

Legion Whey as best protein powder

What We Liked

This is our pick for the best tasting protein powder on our list; our tester Pete rated it a 5 out of 5 for flavor. He noted that the protein powder is fairly sweet, as the brand uses a combination of stevia and OvaSweet. “There is a slight stevia aftertaste. It feels creamy. Would I drink this again, yes, I’d drink this protein powder again.” Pete said that it has what he’d describe as a natural flavor profile—you can taste the vanilla but it’s not overbearingly sweet.  

Pete didn’t notice any negative effects, digestive issues, or weird aftertaste from the Legion Whey+, rating it a 5 out of 5 for side effects. In short, he is a fan of this brand, as they are artificial ingredient-free and third-party tested. Overall, Pete thinks this is a high-quality whey protein isolate supplement. 

What Could Be Improved

However, Pete rated this protein powder a 1 out of 5 on how well it mixed, saying, “The product did not dissolve after 60 seconds. Without blending, there were small chunks of protein powder that floated to the top of the shaker bottle. After blending, it had a smooth and creamy consistency.” For a smoother mix, we suggest using a blender to ensure this protein powder completely dissolves.

If you want to avoid using a blender and simply mix up your drink in a shaker bottle, we recommend Transparent Labs protein.

  • Our thoughts: We like this no-frills, affordable protein powder for everyday use

  • Who it’s for: Folks on a budgetFolks on a budget

Pros

  • More affordable than our other picks
  • 60-day money back guarantee
  • Made in a GMP compliant, FDA-registered facility

Cons

  • Protein does not come from grass-fed cattle
  • Sourced internationally
  • Contains sucralose, an artificial sweetener

Our Thoughts on Nutricost Whey Concentrate 

Nutricost Whey Concentrate is available in eight flavors and three sizes: one-and-a-half pounds, two pounds, or five pounds. It’s non-GMO and gluten free, and we especially like how cost-effective this powder is, as it costs only about .87 cents per serving if you get the five-pound tub.  

What We Liked

Pete was our tester for this protein powder, which he tried in the vanilla flavor. He’s a registered dietitian who also tested and reviewed all of the other options on our list, paying close attention to formulations and ingredients. Pete’s initial reaction to the product was promising, rating it a 5 out of 5 for his first impression. “It comes in a standard size plastic container. The matte label is simple and straightforward, which is in line with the brand being a cost-effective supplement company.” 

Nutricost Whey as best protein powder

He found the instructions easy to follow, and after mixing, said the shake had a “very thin, smooth consistency. It mixed easily and fully dissolved. There were no visible chunks. It did not need additional mixing.”  

After testing, Pete did not notice any adverse effects or digestive issues, rating it a 5 out of 5 for side effects. Overall, we recommend this protein powder for folks looking for the best affordable option. If you’re looking for a less sweet-tasting formula, we recommend Transparent Labs 100% Grass-Fed Whey Protein Isolate.

What Could Be Improved

Pete said that once mixed, this protein tastes like sweet skim milk. Personally, he probably wouldn’t drink this product again because he doesn’t enjoy a vanilla flavor in general, and it was a little too sweet for him. So, if folks want an option that doesn’t have much sweetness, we recommend Heart & Soil’s unflavored protein.

  • Our thoughts: This shake had an incredibly creamy texture
  • Calories per serving: 240
  • Flavor options: Six flavors
  • Who it’s for: Folks looking to lose weight and wanting a protein-focused snack

Pros

  • No artificial flavors or sweeteners
  • Certified vegan
  • Includes digestive enzymes and probiotics

Cons

  • Lower caloric content than other meal replacement shakes
  • More expensive than other options on our list
  • Contains proprietary blends

Our Thoughts on Ka’Chava Superblend Shake

Ka’Chava Superblend Shake is a meal replacement style protein, rather than just protein supplementation. If you’re looking for a protein powder for weight loss, you might consider using Ka’Chava to help support your goals. However, we still recommend talking with a doctor or other healthcare professional before using Huel as a meal replacement or weight-loss tool. 

What We Liked

This product contains about 240 calories per serving, including 25 grams of protein, which makes for a good protein-focused snack. Ka’Chava also has 6 grams of fiber and 26 essential vitamins, which should help keep you feeling satisfied.

Ka'Chava as best meal replacement shake

Pete tested this meal replacement shake, rating it a 5 out of 5 for flavor (he tried the Coconut Acai). “The flavor is overall subtle and the texture is nice and creamy,” he said. “It tastes more like a smoothie not like a juice or a milkshake. The sweetness is just right, not super sweet and not bitter at all.”

Our tester absolutely loved the creamy texture and noted there was no greens flavor, despite the fruits and veggies in the mix. Pete suggests it as a breakfast meal, since it provides a significant amount of vitamins and minerals. It also contains omega-3 fatty acids, which has been shown in research to help support weight loss. 

Pete rated this product’s ability to mix smoothly as a 5 out of 5. “The product mixed well after 60 seconds,” he said. “It was more of a thick like consistency like a smoothie and the texture was slightly gritty in the glass but tasted smooth overall. The look seemed just like a strawberry smoothie and was very pleasing.”

He didn’t experience any adverse effects or digestive issues when testing this product, rating it a 5 out of 5 for side effects.

What Could Be Improved

Ka’Chava does use plant-based protein, which means you may not actually get the full 25 grams, as the bioavailability is lower. That said, the brand includes mainly pea protein, which has been shown to offer high-quality essential amino acids. For those who aren’t married to a plant protein, we recommend considering our Legion protein pick, as it packs 22 grams of protein with full bioavailability.

  • Our thoughts: A well-dosed plant-based protein

  • Who it’s for: Folks looking for a plant-based protein

Pros

  • Contains both pea and pumpkin protein

Cons

  • Pricey
  • Limited flavor options, compared to others
  • Higher in calories than some other picks

Our Thoughts on Swolverine Plant Protein

More than ever before, you can find a wide variety of plant protein options on the market. But that doesn’t mean they’re all high-quality products with an adequate protein serving. Luckily, Swolverine Plant Protein has you covered. This pea- and pumpkin-based protein offers 25 grams of protein per serving with little additional carbohydrates or fats.

What We Liked

“I really enjoyed this product,” Pete said, giving this protein an overall 5 out of 5 for experience. “I did not have any digestive issues, and the plant protein went down really smooth. I didn’t notice any adverse effects.”

Swolverine Plant Protein as best protein powder.

Pete tried out the salted caramel flavor but this one also comes in chocolate cake and vanilla oatmeal cookie. You can also choose two container sizes, including 25 and 30 servings. “The product tastes really nice,” Pete said. “The salted caramel flavor is pretty subtle and not too sweet. It is relatively thick for a plant protein, but the flavor was not overwhelming at all. It was frothy and creamy, though I think it would be better with milk or almond milk.”

Despite the thickness of the product, our testers were impressed with the mixability of this protein. Pete shook the product in a standard shaker cup for about 60 seconds, resulting in a drink that was neither grainy, nor chalky. While it does have a slight plant flavor, it’s not overbearing.

What Could Be Improved

Unfortunately, no product is perfect. One 30-serving container of Swolverine Plant Protein costs $64.99, which is about $2.16 per serving, which isn’t the most budget-friendly. You can opt for a subscription, though, which gives an extra 15% off. That said, this may not fall within every athlete’s budget, in which case, we recommend Nutricost Whey Protein.

Cons

  • Not vegan-friendly

Our Thoughts on Kaged Whey Protein Isolate 

We selected Kaged Whey Protein Isolate as best whey protein powder as it contains 100% pure whey isolate protein powder. Unlike a casein protein, for instance, whey digests faster, making it the perfect ingredient for a quick post-workout refuel.

Kaged Whey as best protein powder

What We Liked

Our tester, Pete, had a positive first impression—rating Kaged a 5 out of 5 on this front. The container has a black label with light yellow lettering. It’s three pounds and contains 44 servings. The label is easy to read, and the container opens and closes easily. The label also includes relevant information, including Informed Sport testing, that it contains 25 grams of protein, plus labels indicating that it is non-GMO and gluten-free. 

He experienced no adverse effects, digestive issues, or aftertaste, rating it a 5 out of 5. Overall, our team thinks Kaged Whey Protein Isolate is a high-quality choice for those wanting clean macros, solid taste, and digestibility.

What Could Be Improved

After tasting this protein powder, Pete found it a bit too sweet for his liking. “The product uses a blend of both sucralose and stevia. The vanilla flavor is subtle; all I really taste is the sweetness of the product.” In terms of consistency, Pete said, “The product is smooth, mixed well, and didn’t froth up when mixed. There was no grittiness or clumping.” He rated Kaged a 3 out of 5 on taste and a 5 out of 5 for sweetness.

Other Protein Powders We Tested 

We tested over a dozen protein powders hands-on in our lab. Here are a few that we considered but didn’t make our list of top picks, and why. 

  • Our team tested Transparent Labs’ 100% Grass-Fed Casein Protein in the Chocolate Flavor, but found it particularly grainy, despite mixing it fully. 
  • Kaged’s Protein Isolate Elite Series didn’t have the best flavor, according to our tester. 

How We Tested and Selected the Best Protein Powders 

We tested and evaluated protein powders and scored them on a scale of 1-5 for factors such as first impressions, easy-to-follow directions, taste, mixability, side effects, and value. Our testers consider the products based on their own experiences and preferences. We then review their testing feedback and data to share our findings and recommendations.

Taste and Texture 

Flavor is a big part of our testing process. We ask our testers to provide feedback on the taste, texture, and pleasantness of the flavor for each protein powder. We rate sweetness on a scale of 1 to 5, based on sweetness strength. A score of 5 is best-tasting, 1 is not drinkable.

We also consider texture, and ask our tester to record any grittiness, clumps, frothiness, or conversely, smoothness and creaminess, when tasting the protein powder drink. 

Formula 

We work with a registered dietitian (RD) during testing to find the most effective and safe supplements, including greens powders, pre-workouts, and, of course protein powders. We look for a high amount of protein in each serving (at least 20 grams) with as few fats and carbohydrates as possible. We also look for protein powders without artificial sweeteners and other additives.  

Mixability  

When mixing a protein powder into liquid, we prepare the product exactly as advised by the brand. We then pay close attention to how well the powder dissolves, wanting to avoid grittiness in the taste and odd textures, like chunks.  

Third-Party Testing 

Whether you’re buying a protein powder or fat burner supplement, we recommend prioritizing a third-party tested product. Third-party testing involves independent verification of safety, purity, as well as nutrition label accuracy. This helps ensure the label on the product is accurate. Third-party testing also checks for harmful substances such as heavy metals, pesticides, and more for safety.  

Legion Whey as best protein powder

For athletes, third-party testing is paramount to knowing that the protein powder they’ve chosen does not contain any banned substances. They should look for products that are certified for sport. Independent testing and certifications help to build consumer trust. The FDA (U.S. Food and Drug Administration) does not regulate supplements, so it’s vital to have independent testing done to ensure safety, accuracy, and quality.  

Value 

When considering value, we place a higher value on brands that source their ingredients in America and have certifications, such as Informed Protein.

How to Find the Best Protein Powder for You 

Everyone has different protein powder needs depending on your fitness goals, dietary needs, allergies, and pre-existing health conditions. People also have different day-to-day diets that involve varying amounts of protein. Some folks may need more than others.  

Here’s what to consider when selecting the best protein powder for you. 

Your Fitness Goals 

Every individual and athlete has distinct fitness goals, like building muscle, losing fat, or improving endurance and strength. And so, the ideal protein powder varies from person to person. To consider what kind of protein powder works best for you, consider your training intensity, recovery needs, and ingredient and flavor preferences. 

Flavors 

It’s important to choose a protein powder flavor that you genuinely enjoy, because sipping it regularly makes it easier to meet your daily protein goals and stick to your routine. A tasty flavor also ensures your protein supplement feels more like a treat than a chore, which will support you with consistency and satisfaction long-term. Finding a flavor that you like, such as cookies and cream to cinnamon bun, is a way to help support your nutrition habits and fitness goals. 

Formula 

As discussed, everyone has their own unique dietary requirements and nutritional goals, so it’s important to check a protein powder’s ingredient list and macronutrient breakdown before purchasing. Proteins have different ratios of protein, carbs and fat. Some are lean and low-carb to promote weight loss, while others have more balanced macros for muscle gain, vegan or vegetarian needs, or as a meal replacement.

Protein Source

Different protein sources work better or worse for different individuals. While whey protein often has the highest protein ratio, plant-based options are more ideal for those looking to avid animal products (or those who may experience stomach upset from whey).

If you’re opting for a whey, we recommend you prioritize grass-fed products as much as possible. Or, if you decide you want a plant protein, look for an option that includes soy, as it has a complete amino acid profile, which you won’t find with other plant-based proteins.

Cost 

Protein powder can be pricey, so you may want to consider your budget when selecting a product for everyday use. Cleaner formulations, meaning those without artificial sweeteners or additives, may cost more because of their higher quality and ingredient sourcing. 

Third-Party Testing 

Third-party testing independently verifies the safety, purity, and label accuracy of protein powders since the FDA doesn’t regulate supplements. This process helps protect you from mislabeling, contamination, and banned substances, building trust and ensuring you can use products with confidence. Independent testing is essential for confirming product quality and safeguarding your health. 

Benefits of Protein Powder 

Protein powder offers several benefits for health and fitness, making it popular among athletes and folks looking to support overall wellness or weight management. 

  • Muscle Growth: Using protein powder helps support muscle growth and repair, especially after lifting. A 2019 study found that participants who consumed protein supplements before and after resistance exercises over 12 weeks experienced greater improvements in muscle growth, strength, and endurance compared with those who did not supplement. 
  • Convenience: Protein powder is convenient and easy to use, making it ideal for busy days. It requires no cooking and can be mixed into shakes or snacks for a quick protein boost on the go. 
Optimum Nutrition Whey as best protein powder
  • Weight Management: Increasing protein intake with supplements can help support weight-loss by boosting satiety and reducing overall calorie intake. Many studies, including a 2020 analysis, have shown that diets higher in protein may lead to greater weight loss, fat reduction, and preservation of muscle during periods of calorie restriction. 
  • Immune Support: Protein is essential for immunity, as it provides critical amino acids for antibodies and other immune system proteins. Research shows that adequate protein intake can help enhance immune function and helps the body defend against infection and disease. 

What to Avoid in Protein Powder 

There are some ingredients we recommend avoiding when choosing a protein powder: 

  • Artificial sweeteners: May cause headaches, digestive issues, and other side effects. 
  • Added sugars: Can add unnecessary calories and spike blood sugar. 
  • Fillers and bulking agents: May cause digestive distress and add little nutritional value. 
  • Thickeners and gums: May cause bloating, gas, or digestive issues for some people. 
  • Artificial flavors and colors: These have no nutritional value and may cause adverse reactions in some people. 

Types of Protein Powder 

There are different types of protein powders, made from various sources. Here are some of them: 

  • Whey protein isolate: Highly filtered to remove most fat and lactose, contains 90% or more protein by weight, rapidly absorbed, and ideal for folks looking for a high protein supplement with minimal carbs or fats. 
  • Whey protein concentrate: Less processed than isolate, retains more fats, lactose, and beneficial compounds like immunoglobulins, usually has 70%-80% protein content, and has a creamier texture.

  • Hydrolyzed whey protein: Whey protein (often isolate) that is “pre-digested” via hydrolysis into smaller peptides, absorbed fastest, potentially easier to digest, and may be suitable for people with sensitivities or elite athletes. 
  • Casein: This other primary milk protein is digested and absorbed much more slowly than whey, which provides a sustained release of amino acids, and is often chosen for nighttime or prolonged recovery. 
  • Plant-based protein: Made from sources like pea, soy, rice, or hemp, suitable for vegans or those with dairy allergies. Some blends provide complete proteins, though they’re usually less concentrated than whey. 
  • Egg protein: Derived from egg whites and contains all essential amino acids and is also low in fat and carbs. An excellent non-dairy alternative for a complete protein. 

Frequently asked questions

How do I take a protein powder?

Protein powder tastes best when mixed with liquid, like water. The recommended daily take for adults over 18 is 0.8 g/kg. This value helps prevent protein deficiency, however, athletes and older adults, for instance, may require a higher value.

It’s best to consume enough protein throughout the day for muscle repair and growth, rather than a particular time. Some studies have cited an anabolic window, recommending protein supplementation within thirty to sixty minutes after exercise, but largely recommend that overall daily intake of protein is more important than timing. 

What is the best protein powder? 

Transparent Labs 100% Grass-Fed Whey Protein Isolate is our pick for the best protein powder overall. It’s a high-quality supplement available in many flavor options. It mixes together easily and is super smooth in consistency. 

Is it good to drink protein every day? 

We recommend focusing on protein-dense whole foods before jumping into a supplement. That said, consuming enough protein from food can be challenging for some. So, opting for a daily protein drink can have plenty of benefits, including muscle gains. If you consume too much protein, it might lead to weight gain, but otherwise, drinking a protein drink daily will likely support your fitness goals.  

What is the cleanest protein powder you can get? 

The cleanest type of protein powder is a powder with no additives, artificial sweeteners, flavors, or colors. It will have limited ingredients and is often labeled as unflavored. Some of the options on our list come in the unflavored variety, so take a look! 

What is the best way to use protein powder? 

The best way to use protein powder is by following the exact instructions on the brand’s packaging to ensure it mixes well according to their directions.
