The Active Ingredient Is: L-Citrulline

L-Citrulline is an amino acid that acts as a precursor to L-arginine and takes part in nitrogen handling and amino acid metabolism in the body.

This product offers L-Citrulline in a pure powder form, described as vegan and free from fillers or additives, reflecting NOW Foods’ emphasis on quality and transparency in sourcing and testing.

What Does L-Citrulline Do?

L-Citrulline helps with the production of nitric oxide, which helps widen blood vessels and supports blood flow and nutrient delivery. It also takes part in the urea cycle to help with ammonia detoxification during exercise, and may support muscle recovery and immune function through these pathways.

These functions line up with EFSA and NHS views on normal physiological processes involved in metabolism and circulation.
