Whey Protein Plus Leucine Promotes Protein Synthesis in Older Adults
A supplement containing 20 grams of whey protein and three grams of leucine consumed after weight training was superior to an equal amount of milk protein for promoting muscle protein synthesis in older adults. Muscle loss, a condition called sarcopenia, is a significant health issue in older adults. Sarcopenia interferes with mobility and quality of life, and decreases metabolic health by reducing one of the most active tissues in the body. Overwhelming evidence shows that older adults can help maintain muscle mass by consuming a supplement containing 20 to 30 grams of whey protein and three grams of leucine at least once a day.
