How We Ranked These
Brands carrying the Non-GMO Project Verified seal on their label or with a stated company-wide non-GMO sourcing policy. Filter is brand-level; we ranked the resulting pool by cost per gram of protein.
All prices verified within the last 24 hours. We re-check every product across all 12 tracked retailers (Walmart, Amazon, iHerb, GNC, Bodybuilding.com, Target, Vitacost, Muscle & Strength, Costco, Tiger Fitness, MyProtein, Transparent Labs) every two hours. Out-of-stock products are excluded from these rankings entirely.

For whey: dairy from cows not fed GMO grains. For plant proteins: source crops (pea, soy, rice) not from genetically modified seed. The Non-GMO Project Verified seal requires third-party verification across the supply chain.
Most relevant for soy and corn-derived ingredients (where ~90 percent of conventional supply is GMO). Less relevant for pea protein (most pea protein is non-GMO by default). For whey, the GMO question is one step removed (cows fed GMO grains, not the whey itself), so the practical impact is small.
No. Organic always includes non-GMO (organic disallows GMOs), but non-GMO doesn't include organic. A non-GMO product can still use synthetic pesticides on feed crops. If you want both, look for organic certification, which includes non-GMO.
Ascent, Garden of Life Sport, KOS, Aloha, Orgain, Promix, Transparent Labs, and Now Sports all carry verified seals on at least their flagship products. Verify on each specific product since not all SKUs from a verified brand are individually certified.
Not necessarily. A protein powder can be Non-GMO Verified and still contain artificial sweeteners, gums, and stabilizers. For a fully clean label, combine non-GMO + 'no artificial sweeteners' + 'no fillers' filters.
Typically 10 to 20 percent more than conventional whey. Smaller premium than organic (which adds 30 to 50 percent). For most buyers who care about supply-chain ethics, Non-GMO is the cost-effective middle path.
