L-Lysine

L-Lysine is an essential amino acid critical for collagen synthesis, immune function, calcium absorption, and the inhibition of Herpes Simplex Virus replication. Lysine directly competes with arginine at the cellular level — reducing the frequency and severity of cold sores and genital herpes outbreaks significantly with consistent use. It also supports bone density, anxiety reduction, and the production of carnitine. Essential, often overlooked, profoundly useful.
