Lysine (L-Lysine) is a basic, essential amino acid required by the body but which the body is unable to produce itself, and which therefore has to be supplied through nutrition. As an important component of collagen and elastin, lysine can be found in particular in meat, egg, milk and fish proteins. Because lysine is highly reactive and therefore heat-sensitive, a lot of lysine can for example be lost during the cooking of foods. With the L-Lysine-Tablets from Sanct Bernhard, you can supplement your diet with 500 mg pure L-lysine per tablet. Vegan, without animal-based ingredients.
