HMB (β-Hydroxy β-Methylbutyrate) is a clinically researched, naturally occurring metabolite of the branched-chain amino acid leucine. HMB normally plays a role in the regulation of protein breakdown in the body, helping to preserve lean muscle tissue.* HMB therefore can help to maintain muscle strength and mass when combined with regular exercise and a healthy diet.* In addition, it may help to enhance recovery from intense exercise.* Take 2 capsules 2 to 3 times daily with food. For best results, use in conjunction with an exercise program.
