Protein & Performance
Third-party-tested protein powders, creatine, and electrolyte formulas for athletes and active adults — scored on the same rubric as the rest of our reviews.
Best Protein Powders, Scored on a Public Rubric
We scored six top Amazon protein powders (whey, casein, plant) on our 6-metric rubric: third-party testing, amino profile, value, and transparency.
Best Creatine Supplements, Scored on a Public Rubric
Creatine monohydrate is one of the most-studied supplements in sports science. We scored five widely-available Amazon picks on our 6-metric rubric.
Best Electrolyte Powders, Scored on a Public Rubric
Side-by-side scoring of six widely-available electrolyte powders on our 6-metric rubric — sodium-to-potassium ratio, sugar content, third-party testing, and value.
Best Creatine for Women, Scored on a Public Rubric
Creatine monohydrate is the same molecule for everyone — no 'women's blend' needed. We scored five third-party-tested picks on dose, form, and price per 5g.
Best Electrolytes for Keto, Scored Sodium-First
Keto depletes sodium fast. We scored five zero-sugar electrolyte mixes on sodium dose, potassium, magnesium, and clean label — so 'keto flu' doesn't sideline your training.
Best Salt Supplements, Ranked by Sodium Dose
If you train hard, eat low-carb, or sweat heavily, plain water isn't enough — you need salt. We scored six salt-forward electrolyte supplements on sodium dose, clean label, and value, led by LMNT.
Best Protein Powder for Weight Loss — High Protein, Low Sugar
The best protein powders for weight loss prioritize grams of protein per calorie, low sugar, and a clean label. We scored five high-protein, low-carb isolates and a plant pick.
Best BCAA & Amino Acid Supplements, Scored on a Public Rubric
BCAAs are only 3 of the 9 essential amino acids — a complete EAA blend or whole protein does more. We scored six widely-available amino formulas on our 6-metric rubric, powders and tablets.
