Overview

L-Lysine Overview

L-Lysine is one of the nine essential amino acids that the human body cannot produce on its own. It plays a vital role in protein synthesis, calcium absorption, and the production of hormones, enzymes, and antibodies.‡

Found in foods like meat, fish, dairy, and legumes, L-Lysine is important for proper growth and muscle turnover. It also has a key role in the body's production of carnitine, a nutrient responsible for converting fatty acids into energy and helping support healthy cholesterol levels already in the normal range.‡

L-Lysine is often noted for its potential in supporting the body's natural defense mechanisms. Research suggests that lysine supplementation can help with overall immune, skin, and muscle health.‡ L-Lysine may also contribute to healthy skin structure and the maintenance of strong bones when combined with other essential nutrients.‡
