The present invention provides a composition comprising HMB and Vitamin D. Methods of administering HMB and Vitamin D to an animal are also described. Vitamin D and HMB are administered to increase muscle mass, strength, and functionality. The combination of Vitamin D and HMB together has a synergistic effect, which results in a surprising and unexpected level of improvement in muscle mass, strength and functionality.

A composition comprising one or more polyphenols, such as oleuropein, rutin, curcumin or quercetin, can treat or prevent sarcopenia, reduce a loss of muscle functionality (e.g. muscle strength, gait speed, etc.), increase muscle functionality, and/or improve recovery of muscle functionality after muscle atrophy. The composition can be administered to an individual who is elderly and/or frail.

The present invention is directed to improving physical and athletic performance and supporting recovery of joints, ligaments, and tendons with collagen peptides and dietary ingredients that physical and athletic performance. The dietary supplement composition of the present invention comprise collagen, preferably in the form of hydrolyzed collagen peptides, in combination with Branched-Chain Amino Acids (BCAA), Creatine Nitrate, Arginine Nitrate, N- acetyl-L-Carnitine, L-Citrulline, Betaine Anhydrous, Alpha-Glyceryl Phosphoryl Choline, Ancient Peat Extract with Apple Fruit Extract, and Caffeine. Physical and athletic performance, as well as recovery from exercise, is improved using this combination of components.
