"My assessment of the data on protein supplementation and resistance exercise reveals that the amount of leucine in a protein supplement has the greatest impact on muscle protein synthesis," said, Dr. Phillips. "Leucine is not only a building block for protein, but a trigger for working muscles to synthesize more protein. In essence, it turns on muscle protein synthesis like a light switch so that over time, there could be greater gains in lean body mass and strength, and subsequently, body composition improvements."
Proteins with the greatest content of leucine include whey protein isolate or concentrate. Whey protein is a milk protein that is considered high-quality due to its amino acid profile and high score for digestibility. Based on the culmination of data inspecting protein types and muscle protein synthesis, whey protein rated higher than other protein sources such as soy, pea or rice.
"The outcome of this review isn't just applicable to strength trainers," Dr. Phillips notes. "As we age, muscle loss becomes prevalent if we don't thwart the decline. Leucine-rich whey protein supplementation, combined with resistance exercise, may be one way to help preserve muscle mass throughout the lifespan."
While more research is warranted to further characterize proteins based on their quality, digestibility and amino acid profile, as well as to identify their impact on the aging population – at this point, consumers should reach for a leucine-containing protein supplement, like whey, to maximize gains from hard workouts.

About the Whey Protein Research ConsortiumThe Whey Protein Research Consortium (WPRC) is an international partnership of dairy cooperatives, associations, processors and multinational companies dedicated to working together to discover and share whey's unique health benefits through scientific evidence since 2003. The WPRC uniquely serves the dairy industry by expanding global usage of whey protein through the research and amplification of its health benefits. The goal of the integrated research efforts is to develop a body of knowledge that establishes measurable whey protein health and wellness benefits, creating a strong foundation for the development of scientific substantiation to support new health, qualified health and structure function claims.
