Lysine is an essential amino acid that is a necessary building block for all proteins. It is needed for proper growth and bond 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.

Another very useful ability of this amino acid is its capacity for fighting cold sore and herpesviruses. Taking supplemental L-lysine, together with Vitamin C with bioflavonoids, can effectively fight and / or prevent herpes outbreaks, especially if foods containing the amino acid arginine and avoided, such as alcohol, processed foods, colas, white flour products, sugar, refined carbohydrates, coffee, and drugs to lessen the chance of an outbreak. Herbal teas are beneficial, but all other teas should be avoided.
