Agmatine Sulfate (AgmaPure)
Also known as: Agmatine, 4-aminobutylguanidine, AgmaPure, decarboxylated arginine
Effective Dosage
500-2600 mg/day (no established dose from provided studies)
What the Science Says
Agmatine is a naturally occurring compound made when the amino acid arginine is broken down by bacteria in the gut and certain tissues. It acts on multiple receptor systems in the body, including NMDA receptors and nitric oxide pathways, which has led to interest in its potential for pain management, mood support, and cognitive function. Most of what we know comes from animal studies and a small number of human trials — solid clinical evidence in humans is still lacking.
What It Doesn't Do
Not proven to build muscle or boost performance in humans. No strong evidence it reliably increases nitric oxide or pumps the way arginine marketing suggests. Not a proven treatment for depression or anxiety — early signals exist but human data is thin. The 'AgmaPure' branding does not mean extra clinical proof exists for this specific form.

Absorption & Bioavailability
Unknown — limited human pharmacokinetic data available. Animal studies suggest it crosses the blood-brain barrier, but absorption and bioavailability in humans has not been well characterized in published research.
Red Flags to Watch For
- Only 3 clinical trials indexed on PubMed despite being sold in over 1,000 registered supplement products — marketing far outpaces the science
- No systematic reviews or meta-analyses exist, meaning there is no high-quality synthesis of the evidence
- Doses used in supplements vary widely (500 mg to 2600 mg+) with no consensus on what is safe or effective long-term
- May interact with medications that affect nitric oxide, blood pressure, or NMDA receptors — consult a doctor if you take any such drugs
- Proprietary branding like 'AgmaPure' can imply superior quality or extra research that may not exist — always ask for the actual studies
