The Active Ingredient Is: L-Citrulline

L-Citrulline is an amino acid that helps the body make nitric oxide, supporting healthy blood flow and vascular function. This product uses the free amino acid form to make its job inside your body easier.

What Does L-Citrulline Do?

It helps support nitric oxide production, which keeps blood flow steady and supports muscle pumps during activity. This means it can support everyday performance and cardiovascular function, in line with EFSA-informed understanding of nitric oxide pathways.
