Beta-hydroxy-beta methylbutyrate (HMB) is a by product or metabolite of the essential amino acid, Leucine. HMB is produced in our body from the proteins in our diet & is also consumed in small amounts from the foods we eat. However, only a small amount (roughly 5%) of the Leucine you eat is converted into HMB. For the production of HMB to reach optimal gram quantities per day, you’ll need 20-50 grams of Leucine. Consequently, getting enough HMB from your diet alone is virtually impossible. HMB 1000 is a high quality, Bodybuilding Sports Nutrition supplement from USN. It adds 1000 milligrams of HMB to your diet per serving. Research has shown that supplementing with 3g of HMB per day helps to slow down a process called proteolysis, the natural process of breaking down muscle tissue that occurs after intense physical activity taking HMB gives the body a head start with muscle recovery by minimising the amount of muscle breakdown & protein degradation after exercise. This means that your body stays in an anabolic state for longer, allowing for more muscle growth.
