Here’s the practical shortlist I’d recommend as of Aug. 1, 2026—prioritizing brands people actually buy/use, decent taste, third-party testing, and broad availability.
Best protein powders to buy
| Pick | Best for | Why it’s worth considering |
|---|---|---|
| 1. Optimum Nutrition Gold Standard 100% Whey | Best default / best value whey | The safest “just get this” pick: widely available, usually reasonably priced, mixes well, and has 24g protein per serving. WIRED named it Best Overall, and NSF’s Certified for Sport database lists ON Gold Standard 100% Whey flavors including Double Rich Chocolate and Vanilla Ice Cream. (wired.com) |
| 2. Dymatize ISO100 | Best-tasting lean whey isolate | Great if you want low sugar/carbs and easy digestion. Dymatize lists ISO100 at 25g protein, ≤120 calories, ≤1g sugar, and Informed Choice lists ISO100 Hydrolyzed Protein Powder as certified. Clean Label Project’s 2025/2026 “Clean Sixteen” also included Dymatize ISO100 Gourmet Vanilla as non-detect for lead, cadmium, mercury, and arsenic. (dymatize.com) |
| 3. Transparent Labs Grass-Fed Whey Protein Isolate | Best “clean ingredient” whey isolate | Good if you want whey isolate with fewer extras and no artificial sweeteners. WIRED picked it as Best Whey Isolate and notes Informed Choice/Informed Protein certifications. (wired.com) |
| 4. Momentous Whey Protein Isolate / Recovery Protein | Best for tested-athlete confidence | A strong pick for competitive athletes because multiple Momentous protein products are listed in NSF Certified for Sport’s database, and Verywell Fit picked Momentous Recovery Protein as its Best for Athletes. (nsfsport.com) |
| 5. Isopure Zero Carb Protein — Unflavored | Best low-carb / unflavored option | A useful pick if you want very low carb and a plain powder for smoothies, oatmeal, or recipes. Clean Label Project listed Isopure Zero Carb Protein Unflavored among its powders with non-detect lead, cadmium, mercury, and arsenic. (cleanlabelproject.org) |
| 6. Premier Protein 100% Whey — Vanilla Milkshake | Best big-box / budget-friendly retail pick | Popular, easy to find, and high-protein per serving; Amazon’s whey best-seller page has listed Premier Protein Powder at 30g protein and 1g sugar, and Clean Label Project listed Premier Protein 100% Whey Vanilla Milkshake among its non-detect “Clean Sixteen.” (amazon.com) |
| 7. Naked Whey | Best minimal-ingredient whey | Good if you want a simpler formula. Verywell Fit chose Naked Whey Chocolate as Best Overall, noting Informed Choice certification and a short ingredient list. Caveat: don’t confuse it with Naked’s Vegan Mass Gainer, which Consumer Reports flagged separately for high lead. (verywellfit.com) |
| 8. Ritual Essential Protein Daily Shake 18+ | Best plant-based premium pick | A good vegan option if you’re willing to pay more. WIRED picked Ritual as Best Plant-Based, and Verywell Fit also highlights Ritual for transparent sourcing. (wired.com) |
| 9. KOS Vegan Superfood Protein | Best-tasting vegan / lifestyle plant protein | Verywell Fit picked KOS as Best Vegan. I’d choose this over many random plant powders, but I’d still be more cautious with plant-based powders due to heavy-metal testing concerns across the category. (verywellfit.com) |
My quick recommendations
- Most people: get Optimum Nutrition Gold Standard Whey.
- Best taste / low sugar: get Dymatize ISO100.
- Cleanest whey isolate vibe: get Transparent Labs Whey Isolate.
- Drug-tested athlete: get Momentous or an NSF Certified for Sport flavor of ON.
- Vegan: get Ritual first; KOS if taste/price matters more.
- Budget retail pick: Premier Protein 100% Whey.
What to watch out for
Protein powders are supplements, and the FDA does not approve dietary supplements for safety/effectiveness before they’re sold, so third-party testing matters. NIH notes that supplement makers—not FDA—are primarily responsible for ensuring premarket safety, and NSF/Informed Choice certifications provide extra assurance around label accuracy and banned-substance risk. (ods.od.nih.gov)
Also, don’t assume “plant-based” automatically means cleaner. Consumer Reports’ 2025 investigation found plant-based products had much higher lead levels on average than dairy-based whey products, and CR advised against daily use for many powders. If you use protein daily, I’d favor third-party-tested whey isolate unless you need vegan. (consumerreports.org)
