Scientific background
Independent researchAgmatine sulfate
Agmatine is formed in the body from the amino acid arginine and acts as a signalling molecule in the nervous system. It is sold as agmatine sulfate in sports and nootropic products.
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 researchAgmatine sulfate
Controlled human research on agmatine for exercise performance is very limited. Published human data are mostly small studies and a long-term case report1.
L-arginine and AAKG
A dose-response meta-analysis of randomised trials found that L-arginine lowered blood pressure in adults2. 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 preferred3.
Evidence limitations
Independent researchThe studies summarised in this guide examined single ingredients. No published study has tested this product or this combination of ingredients.
Agmatine sulfate
There are no large randomised trials showing a performance benefit from agmatine in healthy people. Claims of better "pump" or focus are not established.
L-arginine and AAKG
Studies vary in dose and population2.
Safety & potential risks
- Do not exceed the recommended daily dose.
- Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.
- Keep out of the reach of young children.
Agmatine sulfate
A case report described 5 years of high daily agmatine intake without detected adverse effects1. One case report cannot establish safety for the wider population.
Regulatory status
Sold as a food supplement. No health claims are made for this product.
