L-Lysine is one of the 9 essential amino acids, the molecular building blocks that form proteins. Because L-lysine is water soluble, so it can be easily absorbed and used by the body. This building block of protein acts as a precursor to the synthesis other amino acids. In other words, the body uses L-lysine to naturally produce other amino acids such as carnitine, which is involved in fat metabolism.
Because it is essential in nature, the body does not produce L-lysine and it must be obtained from the diet. Excellent sources of L-lysine are high-protein foods such as eggs, red meat, dairy products, beans, nuts, and fishes. For some, the amount of L-lysine supplied by the diet may not be enough and they may need to take L-lysine supplements to make sure that they are getting enough of it. Athletes and body builders have increased L-lysine needs because of their intensive physical trainings. On the other hand, people on vegetarian and vegan diet can be low in lysine because their diet usually does not include animal-based foods that are high in protein.
L-lysine is an indispensable component of protein-based organs in the body. Proteins are essential components of all cells in the body, especially those that makes up the skin, muscles, hair, nails, connective tissues, and other organs. This water-soluble amino acid is also involved in the production of red blood cells. Whenever you are low in lysine, you can experience fatigue, dizziness, nausea, agitation, blood shot eyes, anemia, stunted growth, and reproductive health problems. So, having enough supply of L-lysine from the diet prevents a wide variety of health problems.
L-lysine helps combat the herpes simplex virus (HSV), which causes cold sores and genital herpes. The anti-viral effects of L-lysine against herpes are due to its ability of blocking the action of arginine, an amino acid that encourages the replication of HSV. One study found that L-lysine is more effective at prevention of HSV outbreak rather than treating an active infection.
L-lysine helps the bones to become stronger by increasing calcium absorption and reducing calcium excretion in the urine. Because having more calcium in the bones prevents bone loss, scientists believe that taking oral lysine supplements can be effective in the prevention of osteoporosis. Additionally, clinical studies recommend that L-lysine together with L-arginine increase the activities of bone-forming cells and improve collagen production.
L-lysine is the precursor to the amino acid L-carnitine. L-carnitine is involved in the conversion of fatty acids into usable energy. L-carnitine has been recommended as a natural remedy for heart failure because of its ability to supply with heart with more energy it needs to improve its pumping action. L-carnitine is also being used as a weight loss supplement for its fat-burning abilities.
