The Active Ingredient Is: L-Arginine Alpha-Ketoglutarate (AAKG)

L-Arginine Alpha-Ketoglutarate is a form of the amino acid derivative used as a blood-flow helper to support normal circulation during physical activity.

This form is combined with Citrulline Malate to help maximise delivery of nutrients to working muscles through improved circulation.

What Does L-Arginine Alpha-Ketoglutarate Do?

Evidence suggests arginine-based compounds may support nitric oxide production, which can influence vascular function during exercise. Effects on performance vary, with some studies showing modest improvements in endurance or recovery indicators.

Dr. Viribay of a university found that arginine supplementation does not consistently improve exercise capacity in healthy individuals, though certain performance markers may be affected. This mechanism relates to the role of arginine in blood flow and metabolic support during high‑intensity activity.

How Citrulline Malate complements this, in combination, is to provide another pathway for nitric oxide synthesis and potentially improve recovery and muscle comfort after strenuous effort.
