Protein Blend for Muscle Synthesis
A study demonstrated that a soy-dairy protein blend is capable of stimulating muscle growth.
A new study published in The Journal of Nutrition demonstrates the benefits of consuming a protein blend for muscle protein synthesis after exercise. The study, conducted by researchers at the University of Texas Medical Branch, Galveston, utilized the proteins from soy, whey and casein consumed after an acute bout of resistance exercise. The results demonstrate prolonged delivery of amino acids to muscles and extended muscle protein synthesis when subjects consumed the blend, compared to a single source of protein alone. This human clinical study for the first time shows that a soy-dairy protein blend (25% Solae brand Supro isolated soy protein, 25% whey protein isolate and 50% caseinate) is capable of stimulating muscle growth to a similar extent as whey protein, through an elevation in muscle protein synthesis and muscle cell growth signaling. In addition, the blend prolonged increase in the rate of muscle protein synthesis from rest and for a longer amount of time than whey protein alone—a quality that could also be important for the aging muscle.—Solae LLC/DuPont Nutrition & Health
