L-lysine is one of the essential amino acids. That means the body cannot produce it on its own; it has to be obtained from food. Amino acids are the raw materials used to assemble proteins, and proteins are needed for tissue renewal and for creating many biologically active substances. L-lysine takes part in the structure of enzymes, hormones, neurotransmitters and antibodies, and it also contributes to collagen formation, the protein framework found in skin and connective tissue.
Most balanced diets provide lysine through protein-rich foods, but certain habits can make an extra intake useful. This product is a food supplement for adults who want to add L-lysine in a simple capsule form. The active ingredient is L-lysine HCl, a stable form of lysine commonly used in supplements, and each capsule delivers a measured amount of the amino acid.
A capsule supplement like this is not a replacement for food. It is meant to be part of a varied diet, and the recommended intake printed on the label should be followed. If you are pregnant, breastfeeding, managing a medical condition or taking regular medication, check with a doctor or pharmacist before use.
