L-Lysine

Lysine is an essential amino acid that has been found to promote therapeutic effects in virus-related conditions. Of particular interest is its possible role in supporting the management of herpes simplex virus, especially in individuals with low dietary arginine intake. Lysine cannot be synthesized in the organism, and its breakdown is not reversible. Therefore, it is imperative to be present in the diet in adequate quantities. Low dietary intake of lysine has been associated with poor appetite, reduced body weight, anemia, enzyme disorders, and other health concerns. Lysine is used therapeutically to enhance children’s growth and to assist gastric function and appetite.

Lysine plays a role in the body’s ability to absorb and conserve calcium and is involved in a variety of physiological functions. Because of its potential to interfere with herpes virus replication, lysine is most commonly used by individuals who experience cold sores or genital herpes.

The major food sources containing high lysine are: fish, chicken, beef, lamb, milk, cheese, beans, brewer’s yeast, and bean sprouts.
