Protein powder is the backbone of most supplement stacks, but the price per tub can be wildly misleading. A 5lb tub for $45 sounds like a deal until you realize it has 30 servings. A $30 tub with 60 servings is objectively cheaper per scoop — and that's the only math that matters.
We track whey concentrate, whey isolate, casein, egg white, plant-based, and hydrolyzed protein powders across Amazon and direct brands, then rank every single one by cost per serving. Filter by minimum protein per serving to cut out the watered-down options, or toggle Amazon off to see what independent brands are offering.
