Herbs of Gold Lysine 1000 + Olive Leaf contains a high dose of lysine to relieve symptoms of facial cold sores.
Lysine is an essential amino acid involved in making proteins in the body and assisting with the metabolism of carbohydrates and fatty acids. Lysine is also an important amino acid required for the biosynthesis of collagen, elastin and carnitine.
The human body cannot synthesise lysine, so it must be taken through the diet. The richest sources of lysine are animal proteins, such as meat and poultry, and to a lesser extent, eggs, beans and dairy products.
