Last updated: June 2026 · Reviewed by the FactoWiki Editorial Team for clarity and source accuracy
Quick summary
Agmatine is a compound made from the amino acid arginine, popular in pre-workouts and studied for nerve pain. Human evidence is still early.
What is Agmatine?
Agmatine (often sold as agmatine sulfate) is a molecule derived from the amino acid arginine. It is used in pre-workout supplements and has been researched for neuropathic pain and mood.
What Agmatine is commonly used for
In supplements, Agmatine is most often included for men's vitality, nerve health support. It is used as nutritional support, not as a treatment for any medical condition — the distinction matters, because the claims on a sales page are often stronger than the evidence allows.
How Agmatine works
Agmatine influences nitric-oxide pathways (the basis for 'pump' claims), interacts with several brain receptors including NMDA and imidazoline receptors, and modulates pain and stress signalling in laboratory studies.
What the evidence says
Here's an honest snapshot of what published research suggests about Agmatine — including where the evidence is limited.
- Agmatine has interesting preclinical and small human research for neuropathic pain and as a neuromodulator, but high-quality human trials are limited. Its pre-workout 'pump' benefits are largely unproven.
- Study quality and doses vary, and a result seen in research doesn't guarantee the same for any individual — use the sources below to check the current evidence on Agmatine rather than relying on marketing claims.
Typical dosage used in studies
Supplement studies and products typically use a few hundred milligrams up to around 1–2 g/day. Long-term human safety data are limited. This is general information from research, not a personal recommendation or a dosing instruction.
Side effects and safety
Agmatine appears generally well tolerated short-term, with mild digestive effects reported. Because it affects blood pressure and brain signalling, caution applies with medications and in pregnancy. As with any supplement, it's sensible to introduce Agmatine on its own, use a trusted brand, and stop if you notice any reaction.
Medication interactions and who should avoid Agmatine
Medication & safety check
Large doses of a single amino acid can compete with others for absorption and, in some cases, affect medication or specific conditions. If you take any regular medication, are pregnant or breastfeeding, or manage a health condition, confirm Agmatine is appropriate for you before starting.
This is general information, not personal medical advice. If you take any medication, are pregnant or breastfeeding, or have a health condition, confirm it's safe to use Agmatine with your doctor or pharmacist first.
