Protein Blend

A protein blend is a mixture of different protein sources, often including whey, casein, soy, pea, rice, or egg proteins. These proteins are typically isolated and purified from their original sources through various processing methods like filtration and drying.

Manufacturers use protein blends to increase the protein content of foods and beverages, aiding in muscle repair and satiety. They are commonly found in protein bars, shakes, sports nutrition products, and sometimes added to baked goods or snacks.

Protein blends are generally recognized as safe (GRAS) by the FDA when used as intended. The FDA regulates protein as a nutrient. JECFA has evaluated various individual proteins and established acceptable daily intakes for some, while for others, no specific limit was set. Evidence suggests adequate protein intake supports muscle health and satiety, but excessive intake may pose risks for individuals with certain health conditions, such as kidney disease.
