The Active Ingredient Is: L-Arginine (Free-form)

L-Arginine is basically an amino acid that acts as a precursor to nitric oxide, a signalling molecule involved in everyday vascular function.

This powder form gives pure free-form L-Arginine with vegan and allergen-free characteristics, handy for flexible dosing and clean-label purity.

What Does L-Arginine Do?

L-Arginine plays a part in nitric oxide production, which supports normal blood vessel function and circulation as part of everyday physiology. It is also involved in protein metabolism and cellular growth processes as part of a healthy nitrogen balance.

EFSA and NHS guidance recognise the importance of these normal physiological roles in supporting cardiovascular and metabolic health via adequate amino acid availability and metabolism.
