Scientific background

Independent research

L-arginine and AAKG

L-arginine is an amino acid used by the body to make nitric oxide. AAKG is arginine bound to alpha-ketoglutarate.

Research evidence

Independent research

L-arginine and AAKG

A dose-response meta-analysis of randomised trials found that L-arginine lowered blood pressure in adults¹. Evidence for improved exercise performance or "pump" is inconsistent; oral arginine is extensively broken down before reaching the circulation, which is why citrulline is often preferred².

Evidence limitations
