The Active Ingredient Is: L-Arginine (Fermented)

L-Arginine is an amino acid that contributes to the production of nitric oxide, supporting normal vascular function during exercise. This formulation uses a fermented form to help with bioavailability and availability for nitric oxide synthesis.

This ingredient is provided in a fermented form to support reliable absorption and supply for nitric oxide–related functions during training.

What Does L-Arginine Do?

L-Arginine contributes to nitric oxide production, which helps promote blood flow and the muscle pump during workouts.

Clinical context indicates that increased nitric oxide can support enhanced blood flow and nutrient delivery during activity, aligning with normal physiological responses to exercise as described in the available evidence.
