Whey Protein Blend – (instantized for easy blending) is an optimal source of protein due to its superior bioavailability and optimal amino acid profile. This highly concentrated, high PER (protein efficiency ratio) protein is favored by serious athletes and body builders because of its ability to support lean muscle mass development and tissue repair. Whey protein is considered to be the optimal protein source for those individuals who are engaged in heavy weight training and power and strength development programs. Numerous studies have shown that whey protein can enhance immune function in animals and is highly effective against common infections such as salmonella infection and Streptococcus pneumonia. More importantly, it can raise blood levels of glutathione, the body’s primary antioxidant, which is found in virtually every cell. As we age, our levels of glutathione decline, which many researchers believe may be why we are more vulnerable to disease.
