Lysine is an amino acid necessary for human health that, however, cannot be naturally produced within your body. It is important for growth and for the promotion of proper nitrogen balance in your body. Being incorporated into many proteins, Lysine acts as a multi-functional agent used for many purposes. Due to its anti-glycation properties, lysine can be of great help when the levels of sugar in the blood are elevated. Beans are a considerable source of lysine, that most people consumer in adequate quantities. That is why vegetarians, whose diet lack of optimal amounts of beans, can become lysine deficient. Most diets provide the right amount of amino acids, even for athletes who are involved in frequent vigorous exercise. For burn patients, though, the required amount of amino acids may be higher than the amount of lysine in diets. According to research, lysine has anti-viral effects when it blocks the activity of arginine. Moreover, it helps your body absorb calcium and decrease the quantity of calcium lost through urine. Lysine interacts with other amino acids to maintain growth, lean body mass and your body’s store of nitrogen. In addition, dietary supplementation with the essential amino acid L-lysine has been shown to promote relaxation in humans with low dietary intake of L-lysine. L-lysine, together with arginine, has been documented to promote healthy hormonal stress responses in humans.
