The Active Ingredient Is: L-Citrulline

L-Citrulline is an amino acid that plays a role in protein metabolism and helps flush away ammonia produced during metabolism, supporting normal cellular function and metabolic processes.

This product delivers L-Citrulline in its natural free amino acid form for optimum absorption and uses a vegan, non-GMO, plant-based formula suitable for vegetarians and vegans.

What Does L-Citrulline Do?

L-Citrulline helps to support nitric oxide production, which may aid normal blood vessel relaxation and circulation, and it also supports ammonia clearance and protein metabolism as part of everyday bodily functions.

Scientific research suggests that these mechanisms may relate to vascular and immune system processes, with expert discussion noting the role of L-Citrulline in these normal functions. [Dr. Schwedhelm from a university found that L-Citrulline supplementation can influence endothelial function.]
