Lysine - Benefits, Deficiency Symptoms And Food Sources
What is Lysine ?
Lysine is an essential amino acid that is a necessary building block for all protein. It is needed for proper growth and bone development in children; it helps calcium absorption and maintains a proper nitrogen balance in adults. This amino acid aids in the production of antibodies, hormones, and enzymes, and helps in collagen formation and tissue repair. Because it helps to build muscle protein,
it is good for those recovering from surgery and sports injuries. It also lowers high serum triglyceride levels. Lysine is an essential amino acid, and so cannot be manufactured in the body. It is therefore vital that adequate amounts be included in the diet.
Uses and Benefits of Lysine
Some nutritionally oriented physicians and dentists recommend taking lysine during an outbreak of canker sores to speed healing. The most promising application of lysine is its use in managing and preventing painful and unsightly herpes sores caused by the herpes simplex virus (HSV). Another very useful ability of this amino acid is its capacity for fighting cold sores and herpes viruses. Taking supplemental L-lysine, together with vitamin C with bioflavonoids, can effectively fight or prevent herpes outbreaks, especially if foods containing the amino acid arginine are avoided. Supplemental L-lysine also may decrease acute alcohol intoxication.
