How we calculate it

Primary ranking: (current listed price ÷ verified servings) × (25 ÷ verified protein grams per serving). This expresses every product at the same 25-gram protein dose. Price per serving remains visible as a secondary metric. We use structured storefront price and availability data, then verify serving and protein quantities from first-party product labels or selected variants. We do not score taste, ingredient quality, or medical suitability.

Prices can change after publication. The merchant page is the final source of truth.
