The Active Ingredient Is: L-Lysine (Hydrochloride)

L-Lysine is essentially an amino acid that serves as a building block for proteins, including collagen, which is important for connective tissue structure.

This formulation uses L-Lysine in the hydrochloride form of pharmaceutical grade purity and is suitable for vegetarians and vegans.

What Does L-Lysine (Hydrochloride) Do?

L-Lysine helps support collagen production and tissue repair, and it can assist with calcium absorption to support skeletal health. It also contributes to immune function through the production of enzymes and antibodies as part of normal physiology.

This information aligns with standard nutrient function concepts and EFSA/UK guidance on the role of essential amino acids in supporting normal body processes.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
