Protein powder has become the secret ingredient for anyone who's ever looked at a smoothie and thought, "You know what this needs? More cow powder." The best protein powders are an easy boost to any of your go-to recipes, from smoothies to muffins to morning waffles. I rely on it to fill in the nutritional gaps when my meals aren't winning any wellness awards. While the recommended daily allowance for protein is just 0.36 grams per pound of body weight, that's the minimum to avoid deficiency, not the sweet spot for optimal health. Depending on how active you are or your dietary needs, your daily protein recommendation may increase. For more on this, check out How Much Protein Do I Need?

Protein powders were once the territory of gym bros trying to bulk up, but the category has since exploded into the mainstream. The powders are now marketed to everyone and available widely, in every form and flavor, and for every dietary preference. Whether you're plant-based, a picky eater, or need a quick nutrient boost, protein powder is your fast pass. But with so many options, fads, and a never-ending list of additives, it's easy to grab the wrong one for your needs. I've sifted through the market to find the best of the best protein powder. (As with any dietary supplement, please consult a medical professional or registered dietitian before consuming protein powder.)

Updated June 2026: I've updated our specs tables and removed discontinued products. I've also updated information, prices, and links throughout.

I've been downing protein powders for years, but for this guide, I put each one through a fresh round of testing. I sampled each powder at least three times to assess taste, texture, and mixability. I mixed the powders with water, milk, and non-dairy alternatives. I also baked them into muffins and blended them into the occasional smoothie because not all of us like our protein straight.

I prioritized powders with minimal to no additives and full transparency in sourcing - no unnecessary fillers, gums, or questionable sweeteners. Solubility was a major consideration, too. I also scrutinized manufacturing practices and third-party testing. Certifications, like NSF Certified for Sport or Informed Choice, mattered (learn more about these below). Every pick is also a complete protein, meaning it contains all nine essential amino acids.

I'll be testing Thorne Whey Protein Isolate.
