What Is Agmatine?
Agmatine is a naturally occurring metabolite of the amino acid arginine, found in tissues throughout the body. It acts as a neurotransmitter and neuromodulator with a variety of actions in the body, including the central nervous system.
How It Works
Agmatine works by interacting with various molecular targets, including neurotransmitter systems, ion channels, and nitric oxide synthesis. These interactions contribute to its neuroprotective and cognitive-enhancing effects.
Who It's Best For
Individuals looking for cognitive enhancement, mood stabilization, or neuroprotection benefits. It may also be useful for those with a family history of neurodegenerative diseases.
Who Should Avoid It
People with kidney disease or gastrointestinal problems should avoid agmatine. It is also not recommended for pregnant or breastfeeding women.
Dosage & Usage Tips
For optimal absorption, agmatine should be taken on an empty stomach at a dose of 500-1000 mg once daily. It's always wise to start with a lower dose and gradually increase as needed.
Buying Advice & Quality Tips
Look for products that are third-party tested for purity and potency. Avoid products with unnecessary additives or fillers.
Price & Value
Given its potential cognitive and mood benefits, agmatine offers good value for money compared to other nootropic supplements.
Final Verdict
Agmatine is a promising supplement for cognitive enhancement and mood stabilization. While further research is needed, current evidence supports its safety and efficacy.

RESEARCH SUMMARY: Agmatine
KEY FINDINGS:
Neuropathic Pain
- Agmatine sulfate significantly reduced neuropathic pain intensity in patients with painful small fiber neuropathy (SFN) resistant to conventional medications.
- Study involved 11 patients diagnosed with SFN who completed a 2-month treatment with 2.67 g/day agmatine sulfate, resulting in an average pain reduction of 46.4% (p < 0.00001).

Spinal Cord Injury
- Agmatine administration post-spinal cord injury (SCI) reduced nitric oxide levels and improved motor function recovery in rats.
- Study included 40 rats subjected to SCI, treated with 50 or 100 mg/kg/day agmatine for 10 days, showing significant functional improvements compared to controls.

Blood-Brain Barrier Stabilization
- Agmatine treatment stabilized the blood-brain barrier (BBB) and reduced permeability in a rat model of transient cerebral ischemia.
- Study involved 34 rats subjected to middle cerebral artery occlusion, treated with 100 mg/kg agmatine, resulting in improved BBB integrity as assessed by MRI.
