The Active Ingredient Is: L-Lysine

L-Lysine is a vital amino acid and a core building block for proteins in the body. This powder formula gives pharmaceutical-grade L-Lysine as the single active ingredient, with plant-based excipients backing a vegan, allergen-conscious process in a GMP facility.

This product is made in the USA with globally sourced ingredients and contains no fillers beyond inactive, plant-derived components used for formulation.

What Does L-Lysine Do?

Scientific research suggests L-Lysine plays a part in collagen synthesis and immune system support, and it helps with the absorption of minerals such as calcium, iron and zinc. It also acts as a precursor to carnitine, aiding fat metabolism and cellular energy production.

The main benefit lines up with normal physiological functions and EFSA guidance on amino acids and protein synthesis, rather than disease treatment or prevention.

This product isn't intended to diagnose, treat, cure, or prevent any disease.
