What it is

Metamyosyn Protein Blend is a proprietary mix of proteins designed to support muscle health. It typically combines whey protein isolate, milk protein isolate, and egg white protein. These sources are processed to create a blend with a specific amino acid profile.

Why it's used

Manufacturers use Metamyosyn Protein Blend to increase the protein content of foods, particularly those marketed for sports nutrition or meal replacement. It is commonly found in snack bars, energy bars, and powdered supplement mixes.

Health notes

Metamyosyn Protein Blend is a food ingredient and is generally recognized as safe (GRAS) by the FDA when used as intended. Protein is essential for muscle repair and growth. Regulatory bodies like JECFA and EFSA have evaluated various protein sources, but specific evaluations of proprietary blends like Metamyosyn are not typically published. High protein intake is generally safe for healthy individuals, but excessive amounts may pose risks for those with kidney conditions.
