L-Lysine Monohydrochloride

L-Lysine is an essential amino acid — meaning your body cannot produce it and must get it from diet or supplementation. It plays a critical role in collagen synthesis (supporting skin, tendons, and bones), calcium absorption, immune function, and the production of enzymes and hormones. This monohydrochloride powder form is highly bioavailable and easy to mix into feed or water. It's widely used for horses, livestock, and cats to support immune health and tissue repair, and is equally beneficial for human supplementation.
