The Active Ingredient Is: Lysine (Free Form)

Lysine is an essential amino acid that the body cannot make and must be obtained from the diet or supplements. This formulation uses free-form L-lysine, commonly available as L-lysine HCl in supplements, for high bioavailability.

This form is supplied as free-form lysine, intended to support daily protein synthesis and tissue maintenance as part of normal metabolism.

What Does Lysine (Free Form) Do?

Lysine helps support immune function and is involved in collagen formation, which contributes to healthy skin and connective tissue. It also participates in calcium absorption and immune regulation, with a mechanism that involves competition with arginine for cellular uptake.

Dr. Milner of the University of Kansas found that lysine competes with arginine for cellular uptake, which is a simple explanation of its role in supporting normal physiological processes.
