The formula supports your muscles and helps prevent muscle loss, as well as maintain and grow muscle mass and strength, which might otherwise decrease as a result of natural aging. HMB is a bioactive metabolite of the amino acid leucine. HMB has been shown to help maintain muscle function and promote muscle growth, especially for those over 65. HMB has beneficial effects on muscle mass, helping to preserve muscle structural integrity and promote muscle growth. It also supports performance in both endurance and resistance training. Vitamin D3 also has well-documented benefits for muscle health and healthy bone density. Furthermore, vitamin D3 promotes both metabolism and healthy muscle function. Vitamin D also supports healthy mitochondrial function and energy consumption, which may also contribute to promoting muscle strength. Furthermore, vitamin D helps inhibit inflammatory factors that also affect muscle health.
