Here at the Strategist, we like to think of ourselves as crazy (in the good way) about the stuff we buy, but as much as we’d like to, we can’t try everything. Which is why we have People’s Choice, in which we find the best-reviewed products and single out the most convincing ones. (You can learn more about our rating system and how we pick each item here.)

And while we’ve written about lots of supplements and meal replacements before — including 8Greens Supplements, a high-protein meal-suppressing cereal, and a Japanese meal replacement — here, we’ve rounded up the best protein powders, as praised by the most enthusiastic reviewers on Amazon.

Best-rated protein powder

Over 3,000 five-star reviewers gave this protein powder high marks. One calls it “the best-tasting protein I’ve ever had,” adding, “I don’t write many reviews, but this stuff is life changing. Mix it into cold brew and blend with ice and it tastes like a Starbucks Frap. Blend it with a banana and cinnamon and it tastes like a speculoos cookie.” A few complain that it’s too sweet, but one advises customers to “check the ingredients first, or don’t expect vanilla-ice-cream flavor to not taste sweet. This tastes better than most powders I’ve tried, and if it doesn’t taste that great to you, toughen up, princess.”

Another admits he has “easily spent over $20,000 on this product over the course of time” because “it’s the very best.” A fourth reviewer searched endlessly for a “low-carb, low-sugar protein powder” and was stumped until he “came across this bad boy.” He writes, “I don’t understand how anyone could complain about [the] taste. I tried using water again, and for the first time ever (trying to be healthy as possible), and holy heck, it was just as delicious as using milk.” And as this reviewer concludes, “Holy protein, Batman! This protein is top-notch stuff. You really cannot beat it. It has an excellent taste, mixes extremely well, and does exactly what you want 100 percent whey protein to do.”

Best-rated (less expensive) protein powder

If you’re just getting into protein powders and don’t want to commit to a full jar, these single serve packs are a nice way to try it out. But given that about 70 percent of reviewers give this Iconic Protein Powder a five-star rating, and more than half of those describe how great the taste is, it might become a quick favorite. “Mixed with unsweetened vanilla almond milk, it tastes straight up like melted chocolate ice cream,” one writes of the chocolate truffle flavor. Another says this is “BEST tasting vanilla I’ve ever had and it leaves no after taste.” Reviewers also describe the powder as fine, which means it mixes well into almost anything. “I can put it with Greek yogurt without getting chalky,” one writes, while another says it “tastes great mixed with water or non-dairy milk.” It even works “Blended into shakes, or stirred into my coffee,” according to another user. Reviewers also appreciate that it is low in calorie and low in sugar. “It is sweetened with monk fruit extract, which is a safe sweetener alternative to sugar,” one reviewer says, adding, “So this product is great for diabetics or anyone looking to reduce sugar intake.”

Best vegan protein powder

Vega Sport Premium Protein, Vanilla

“On Sundays, I do a very intense and lengthy workout. Before Vega Sports protein powder, after my workout I was always exhausted and just wanted to sit on the couch and browse the internet. However, after I started taking this protein powder, I’m always energized,” one reviewer raves. Many more call this the best vegan protein powder out there, including one who says, “This one is creamy (vanilla) and also has a ton of protein, probiotics, and almost no carbs.” Another thinks it’s not just the best vegan option but the best overall protein powder: “One of the best protein shakes I’ve ever had (vegan and non-vegan). It has so much protein (30 grams per serving) and little to no aftertaste from the stevia.” Lots of reviewers appreciate how smooth and quick to dissolve the mix is, including one who raves, “You don’t need a blender; just mix it into water with a spoon. The result is smooth, creamy, and delicious; no bad chemical taste or aftertaste; not chalky or lumpy or gritty.”

Best carb-free protein powder

Isopure Zero Carb

More than one-fifth of reviewers mention this protein powder’s lack of carbs. “I love that this is only 100 calories and no carbs but 25 grams of protein per serving, and it’s also low fat or fat free, depending on the flavor,” writes one shopper. All these elements make this a popular powder among dozens of users on many types of diets. Someone on Atkins explains, “It not only has a fantastic amount of protein (50 grams in two scoops, a serving), it also has tons of vitamins and minerals that are otherwise hard to get,” while someone on a Keto diet writes, “This is a great meal replacement for a quick lunch.” Reviews are mixed on the taste of this powder because there’s no added sugar, but one customer thinks it’s a good thing: “Isopure has been my favorite protein to use, as it simply provides what your body needs without adding unnecessary additives or diluting itself with carbohydrates and sugars.”

Best peanut-butter protein powder


“Hi, I’m a peanut-butter addict. No, really,” confesses one reviewer. “As a result, I have struggled to lose weight. I hate most natural peanut butters but love Skippy Natural (probably too much). I saw PBFit and decided to try it, as it contains very little of the fat that the butters do. I love the taste, and I’m starting to see results on the scale.” And this user isn’t the only “peanut-butter addict” who switched to this protein powder to cut back. One “PB addict” celebrates finally having peanut butter again, noting, “I thought I would never be able to have peanut butter in my house again. Now I can enjoy peanut butter without the guilt or the pounds packing on.” A peanut-butter “fiend” thinks this powder is “the tastiest by far. Hands down,” compared with other options. And many more call it “heaven,” including one who adds, “It is absolutely amazing in all smoothies and protein shakes, and it doesn’t make a mess in your blender at all. We stocked up and added it to our emergency food supply.”

Best unsweetened protein powder


“I’m a weight lifter and was looking for some sugar-free, unsweetened whey protein for my post-workout shakes since I’ve nixed added sugar and artificial sweeteners in my diet. This whey fit the bill,” explains one reviewer. Another bought this one “because it is completely unsweetened (who needs extra sugar?!) and flavorless,” noting, “I’ve gotta say, it is pretty darn good.” Many reviewers comment on how smooth and non-chalky the texture is, including one who says, “This is how you know the makers of this product pay very close attention to detail to make sure people will have the best product. It’s unflavored and unsweetened, and it feels great when you take it with water.” One reviewer even compares it to a milkshake, concluding, “Best protein ever. I love how foamy it gets. It’s like having a milkshake but healthy and protein packed.”
