L-lysine, along with L-arginine and L-histidine, belongs to the group of essential amino acids. Since the body cannot produce this amino acid itself, lysine must be obtained from food. As a counterpart to the amino acid L-arginine, L-lysine is part of a balanced system. If the balance is skewed in one direction due to an unbalanced diet, this can lead to an imbalance of amino acids in the body. In addition to the amino acid lysine, L-Lysine Plus from Pure Encapsulations also contains the trace minerals selenium and zinc, which contribute to the normal functioning of the immune system and protect cells from oxidative stress. This dietary supplement, made from pure substances, is ideal for meeting increased needs, as well as the requirements of a predominantly vegetarian or vegan diet. The amino acid L-lysine is involved in the endogenous synthesis of L-carnitine. L-Lysine Plus is available in capsule form and is well tolerated by sensitive individuals. Pure Encapsulations offers high-quality products—free from unnecessary additives and preservatives, artificial colors, and trans and hydrogenated fats. These scientifically proven nutritional supplements are particularly well-tolerated and bioavailable.
