Promote muscle growth

Muscle mass naturally reduces as you become older. This frequently results in weight gain and increases the risk of numerous chronic diseases. However, with a mix of strength exercise and a healthy diet, this negative change in body composition can be slowed, stopped, or reversed. Strength training combined with a high protein diet or protein supplementation has been demonstrated to be an effective preventive strategy. High-quality protein foods, such as whey, are very effective.

Whey is high in leucine, a branched-chain amino acid. Leucine is the most anabolic (growth-promoting) amino acid. As a result, whey protein is beneficial for preventing age-related muscle loss as well as improving strength. Some studies suggest that whey protein may be somewhat better for muscle building than other forms of protein, such as casein or soy. However, unless your diet is already deficient in protein, supplements are unlikely to make a significant effect.
