The Active Ingredient Is: L-Lysine (L-lysine HCl)

L-Lysine is an essential amino acid that the body cannot produce itself, necessary for normal protein synthesis and overall metabolic balance.

This formulation presents L-lysine in the HCl form as a vegetarian capsule, sourced to support dietary needs for individuals with higher requirements.

What Does L-Lysine Do?

L-Lysine helps support calcium absorption and bone health by aiding in mineral utilisation and retention in the body.

Research indicates L-Lysine is involved in supporting stress responses and may participate in reducing glycation processes, contributing to normal ageing-related tissue maintenance. Dr. Civitelli of the University of Bologna noted a role in calcium-related processes related to bone health.
