Whey isolate protein powder

Whey isolate is a more heavily filtered form of whey protein, generally resulting in a higher percentage of protein by weight and less lactose, fat, and carbohydrate than whey concentrate. That additional processing typically makes isolate more expensive per container, though not always more expensive per gram of actual protein once serving size and protein content are accounted for. This page includes only products identified as whey isolate, so you can compare nutrition within that single category rather than across mixed whey types. Isolate is still a dairy-derived product and is not appropriate for a vegan diet; anyone with a dairy allergy or sensitivity should check the specific ingredient and allergen statement for each product rather than relying on the "isolate" label alone, since formulations and blending with other ingredients vary by brand.
