The Active Ingredient Is: L-Lysine (Lysine) - L-Lysine hydrochloride

L-Lysine is an essential amino acid that plays a vital role in building body proteins and supporting tissue growth and repair.

This form is pharmaceutical-grade L-lysine hydrochloride, supplied as a single-ingredient supplement with minimal excipients for encapsulation.

What Does L-Lysine Do?

L-Lysine aids in protein synthesis and is involved in normal immune function and tissue repair.

This nutrient supports routine physiological processes and, in research contexts, has been associated with reduced recurrence and perceived severity of cold sore outbreaks in susceptible individuals, alongside broader roles in growth and calcium utilisation.

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