What our research found about protein powders
Protein powders differ in the protein source (whey, casein, egg, beef, pea, rice, blends), sweeteners, flavors and thickeners. Unflavored whey with one or two ingredients is the simplest label; flavored and “clean” plant blends add sweeteners such as stevia, monk fruit or sucralose, natural flavors, gums and sometimes oils. Servings also differ: compare grams of protein per scoop and grams of scoop weight rather than the tub size.
Contaminants are a real consideration. Consumer Reports’ 2025 testing of protein powders and shakes found that the average lead level was higher than in its 2010 tests, with plant-based products averaging about nine times the lead of dairy-based ones, and its food-safety researcher advised against daily use of most protein powders. Third-party certifications such as NSF Certified for Sport and Informed Sport test batches for banned substances and contaminants. Eating protein from food is the baseline; powders are a convenience.

What to compare
- Protein source. Whey, casein, collagen, beef, egg and plant proteins differ in amino acids and allergens.
- Protein per scoop. Compare grams of protein and scoop weight, not tub size.
- Sweeteners and flavors. Unflavored versions avoid sweeteners; flavored ones list stevia, monk fruit, sucralose or sugar.
- Testing and certification. Look for NSF Certified for Sport, Informed Sport, or published heavy-metal testing by lot.
