*Percent Daily Values are based on a 2,000 calorie diet. Your daily values may be higher or lower depending on your calorie needs.

The Active Ingredient Is: L-Lysine

L-Lysine is a vital amino acid that serves as the building block for protein making, helping keep tissues and repair going.

This form arrives as a vegetarian capsule housing L-Lysine, the main active ingredient in this product, with plant-based capsule materials and light excipients to help keep formulation solid.

What Does L-Lysine Do?

L-Lysine helps support calcium absorption and retention and supports healthy nitrogen balance, contributing to normal bone and vascular health processes. It also supports a balanced stress response and may help inhibit glycation, a process linked with tissue ageing.

Dr. Smriga of the University found that daily intakes in the 500–1000 mg range can help support calcium metabolism and promote relaxation in individuals with low dietary intake, aligning with its role in supporting normal physiological functions.

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