What it is

This is a blend of different protein sources, often including whey, casein, and plant-based proteins like soy or pea. The exact composition is proprietary, meaning the manufacturer keeps the specific formula a trade secret. It is designed to provide a concentrated source of protein.

Why it's used

Manufacturers use proprietary protein blends to increase the protein content of foods, aiding in satiety and muscle support. They are commonly found in protein bars, shakes, and other sports nutrition products.

Health notes

Protein blends are generally recognized as safe (GRAS) by the FDA when used as intended. Regulatory bodies like JECFA and EFSA have evaluated various individual protein sources used in these blends. While protein is essential for bodily functions, excessive intake from any source should be discussed with a healthcare provider. Evidence regarding the specific health impacts of proprietary blends is limited due to their varied and undisclosed compositions.

Allergen info

This blend may contain major allergens depending on its specific ingredients. Whey and casein are derived from milk. Soy is also a major allergen. Consumers should check the product's ingredient list for specific allergen warnings.
