HMB helps you gain lean muscle mass with its anti-catabolic effect. HMB prevents muscle breakdown and protects your hard earned muscle mass. According to studies, HMB decreases muscle membrane damage after exhausting exercises. HMB has a role in synthesis of muscle tissue in response to exercise and it helps to decrease body fat - this is achieved indirectly from the gain in lean muscle mass.

TwinLab HMB Fuel:

• Gain lean muscle mass
• Prevent muscle catabolism and muscle breakdown
• Fast muscle repair
• Reduce body fat

HMB is a metabolite of the amino acid leucine. A study conducted on humans showed that those who supplemented with HMB experienced enhanced strength, greater endurance, and increased fat loss. Its ability to boost endurance alone is an incredible result. A seven week long study showed a much greater gain in muscle when a group of 28 participated in a regular weight-training program.

One hypothesis suggests that HMB directly inhibits the catabolism of muscle proteins during stressful events such as exercise. Another possibility is that HMB is a structural component covalently linked to tissues or cell membranes and is destroyed when under stress. Thus, supplementation with HMB may both prevent muscle breakdown as well as accelerate tissue repair after exercise.
