It can reduce muscle protein breakdown, helping to maintain muscle mass especially during high-intensity training or under the risk of muscle loss (such as fat loss and aging). Meanwhile, it promotes muscle repair, shortens post-exercise recovery time, and indirectly improves athletic performance. As a supplement, it is often added to sports nutrition products, suitable for fitness enthusiasts, athletes, or groups in need of preventing muscle attenuation. Its calcium salt form can also supplement a small amount of calcium, achieving mineral supplementation at the same time.
