A 2020 human study found ADHD children have elevated (not deficient) agmatine, likely compensatory. A 2021 rat study showed agmatine improved ADHD-relevant cognition. Neither supports agmatine as a human ADHD treatment.
Agmatine’s nitric oxide synthase and NMDA receptor mechanisms overlap with migraine’s known biochemistry — but no study has tested agmatine directly in migraine patients. An honest evidence-gap review.
What the actual PubMed-indexed research says (and doesn’t say) about agmatine and testosterone — a 2025 testicular-injury protection study and a 1994 hormone-release finding, not a human boosting trial.
A 2020 open-label pilot study gave agmatine sulfate to small fiber neuropathy patients for two months and measured a 46% drop in pain. Here’s exactly what the trial did, who it studied, and why it isn’t proof yet.
Agmatine reduces tactile allodynia and lowers glucose in streptozotocin-diabetic rat studies. Here’s what the animal evidence actually shows, and why no diabetes-specific human trial exists yet.
Explore how agmatine may support workout performance through nitric oxide regulation, vasodilation, and endurance pathways. Evidence-based, no hype.
Can agmatine sulfate support sleep quality by calming stress and pain signals? An honest, evidence-informed look at the proposed mechanisms.
A balanced look at human and animal research on agmatine sulfate for pain relief, including two clinical studies and where the evidence still falls short.
How agmatine may reduce opioid tolerance via NMDA receptor inhibition and nitric oxide modulation. Evidence-based review with peer-reviewed citations.
Agmatine may support memory and neuroprotection via NMDA and imidazoline receptor activity. Review what preclinical research shows and where evidence stops shor
How agmatine sulfate interacts with nitric oxide synthase isoforms, what preclinical research shows, and what bodybuilders should realistically expect.
Explore how agmatine may protect brain cells by blocking excitotoxic NMDA receptor activation. Evidence-based overview with cited research.
