Milk Protein Isolate
What is Milk Protein Isolate?
Milk Protein Isolate is a highly concentrated form of protein derived from milk. It is made by filtering out much of the lactose and fat content from milk, resulting in a dry powder composed of 90% or more protein.
It is primarily used in food and beverage products to increase protein content, often favored for its complete amino acid profile which supports muscle growth and repair. Health evidence tends to be positive, highlighting its role in muscle maintenance and recovery.
Milk Protein Isolate is generally well-tolerated by individuals who are not lactose intolerant, as most of the lactose is removed during processing. However, it is sourced from milk, making it unsuitable for vegans and those with milk allergies.
Commonly found in: Protein powders, Protein bars, Meal replacements, Sports drinks, Dairy alternatives
