L-lysine Hcl

Drug Details

L-Lysine HCl, or L-Lysine hydrochloride, is the hydrochloride salt form of L-Lysine, an essential amino acid vital for protein synthesis and various bodily functions. As the body cannot produce L-Lysine, it must be obtained through diet or supplements. L-Lysine HCl is commonly used to support immune function, particularly in managing cold sores caused by the herpes simplex virus, and may aid in collagen production, promoting healthy skin and tissue repair. It also plays a role in calcium absorption, contributing to bone health. While generally safe, some individuals may experience side effects like stomach discomfort or diarrhea. Consulting a healthcare professional before starting supplementation is advisable, especially for those with existing health conditions or who are pregnant or breastfeeding.
