L-Isoleucine is one of the nine essential amino acids that is not produced in the body. It can be obtained from animal sources like liver, fish, eggs, chicken, meat and vegetable sources like rye, cashew nuts, almonds, lentils, chickpeas and soy proteins. The metabolism of L-Isoleucine takes place in muscle tissue. It is needed for the formation of hemoglobin and stabilizes and regulates blood sugar and energy levels. It is also known to increase endurance levels and helps in the recovery of muscles after exercise. It strengthens the immune system’s ability to fight off infections and increases the level of growth hormones and insulin to maintain the body’s balance. A deficiency leads to a number of physical and mental disorders with symptoms similar to hypoglycemia.

L-Leucine- Leucine is a hydrophobic essential alpha amino acid, which as an additive under the name L-Leucine has an E number E641, which classifies this amino acid as a flavor enhancer. The natural source of leucine includes whole wheat products, several species of nuts and brown rice. L-Leucine is one of the most abundant amino acids found in skeletal muscle tissues. L-Leucine became in recent times a very popular dietary supplement, particularly with the body building communities, because of the evidence that it slows down the degradation of muscle tissue in rats by elevating the production of muscle proteins. There are additional claims in circulation, which state that L-Leucine also controls the nitrogen balance and aids to the mental and cognitive abilities during high power workouts.

L-Valine is an amino acid in combination with L-Leucine and L-Isoleucine. These amino acids maintain everyday life and offer maximum support. L-Valine is acquired from vegetable and animal protein. L-Valine regulates the immune system and is involved in the protein synthesis and glucose metabolism. L-Valine is effective in muscle growth as well as tissue repair. L-Valine is a part of the muscle metabolism and is also effective in the nitrogen balance in the body. L-Valine is found in the muscles in high concentration, but this cannot be done on its own in the body and has to be acquired through dietary or food supplements. L-Valine has stimulating effect and maintains the nitrogen in the body. It is effective for repair as well as growth of tissues and for muscle metabolism. Adhering to the label directions is highly recommended. This is normally safe and has no side effect until now. However, for the dietary supplement consulting the physician before use is the best.
