How the ranking works
01
Why price per gram of protein?
A cheaper tub isn't cheaper protein. Two whey powders at the same shelf price can differ 30% in protein density. Ranking by $/100g protein is the only honest way to compare what you're actually buying.
02
How is the number calculated?
Total price ÷ (servings × grams of protein per serving), read from the verified label. The full formula and our confidence flags live on the methodology page .
03
How fresh are these prices?
Synced from Amazon every few hours. The timestamp above is real — the price may have changed since, so we always link you straight to the live listing to confirm.
