Protein Isolate

Definition

Protein isolate is a type of dietary supplement that provides a highly concentrated form of protein, with most fats and carbohydrates removed.

Scientific / Technical Definition

Protein isolate is produced by extracting protein from a food source, such as milk, soy, or peas, using methods that remove non-protein components, resulting in a product that typically consists of 90-95% pure protein. This process makes it particularly suitable for people who want to ingest more protein without added calories from fats or carbohydrates.
