Leucine Benefits - Secrets of Essential Amino Acid

Leucine is an essential amino acid and is one of the branched chain aminos. Like Isoleucine and valine, it works to promote the health of muscle and itself can be used as fuel. It has been shown to promote healthy blood sugar levels and helps to promote healthy growth hormone production.

Leucine Benefits

Leucine works with the amino acids isoleucine and valine to repair muscles, regulate blood sugar, and provide the body with energy. It also increases production of growth hormones, and helps burn visceral fat, which is located in the deepest layers of the body and the least responsive to dieting and exercise.

Leucine, isoleucine, and valine are branched-chain amino acids (BCAAs), and all three of them help promote muscle recovery after exercise. Leucine is the most effective BCAA for preventing muscle loss because it breaks down and is converted to glucose more quickly than isoleucine and valine. Increased glucose supplies prevent the body’s cannibalization of muscle for energy during intense workouts, so it is no surprise that this amino acid supplement is popular among professional body builders. Leucine also promotes the healing of bones, skin, and muscle tissue after traumatic injury, and is often recommended for those recovering from surgery.

Leucine is necessary for the optimal growth of infants and for the nitrogen balance in adults. It appears to have no particular therapeutic role, but it is vital in supporting functions. Leucine lowers elevated blood sugar levels and is necessary in promoting the healing of bones, skin, and muscle tissue. Leucine is used as a source for the synthesis of blood sugar in the liver during starvation, stress, and infection to aid in healing.

Leucine benefits in regulating protein metabolism in the body. The availability of leucine is especially important in controlling the net synthesis of protein. Therapeutically, leucine as well as isoleucine benefits and valine can be used as a means of minimising protein loss in patients and undergoing surgery.

During times of starvation, stress, infection, or recovery from trauma, the body mobilizes leucine as a source for gluconeogenesis (the synthesis of blood sugar in the liver) to aid in the healing process. It has recently been suggested that leucine may have beneficial therapeutic effects on the prevention of protein wasting, as it occurs during starvation, semi-starvation, trauma, or recovery after surgery. Insulin deficiency is known to result in poor utilization of leucine; therefore, individuals who suffer from glucose intolerance may require higher levels of leucine intake. It has also been recently suggested that leucine has anabolic effects, thereby preventing muscle protein

Unique metabolic roles for leucine were reported first for regulation of skeletal muscle protein synthesis. During catabolic periods, such as fasting or energy restriction, supplementation with leucine or a complete mixture of the three BCAAs leucine, isoleucine, and valine stimulates muscle protein synthesis.. Likewise, leucine supplementation stimulates recovery of muscle protein synthesis after exercise. The molecular mechanisms for the actions of leucine in protein synthesis are now known to involve regulation of phosphorylation events and components of the insulin signaling pathway in translational control of muscle protein synthesis .
