Whey protein powder

Whey protein is a milk-derived protein sold in three common forms: concentrate, isolate, and hydrolysate, which differ mainly in how much lactose, fat, and carbohydrate remain after processing. Isolate is typically more filtered and higher in protein per scoop; concentrate usually costs less and retains more of the original milk components; hydrolysate is pre-broken-down for faster digestion and often costs more. This page includes products from any of these three whey forms, so you can compare them side by side rather than choosing a form first. Because whey is dairy-derived, it is not suitable for a vegan diet and may not suit people with a dairy sensitivity — check each product's ingredient and allergen information directly. Use the protein and calorie columns per 25 grams of protein to compare nutrition across forms and brands rather than relying on container size alone.
