L-Lysine is an essential amino acid that the body cannot synthesize and must be obtained through diet or supplementation. It is vital for protein synthesis, calcium absorption, and the production of hormones, enzymes, and collagen.
In athletes, lysine supports muscle repair, immune function, and joint health, contributing to overall recovery and performance. It is also involved in carnitine production, which plays a role in fat metabolism.
Its antiviral properties, especially against the herpes simplex virus, are an added benefit for general wellness.
