A study published online in the Journal of Applied Physiology shows additional benefits of consuming a blend of soy and dairy proteins after resistance exercise for building muscle mass. Researchers from the University of Texas Medical Branch found that using a protein blend of soy, casein and whey post-workout prolongs the delivery of select amino acids to the muscle for an hour longer than using whey alone. It also shows a prolonged increase in amino acid net balance across the leg muscle during early post-exercise recovery, suggesting prolonged muscle-building.

This new research, using state-of-the-art methodology, builds on an earlier publication reporting that a soy-dairy blend extends muscle protein synthesis when compared to whey alone, as only the blended protein kept synthesis rates elevated three to five hours after exercise. Together, these studies indicate that the use of soy-dairy blends can be an effective strategy for active individuals seeking products to support muscle health.
