Infobox references

6-Hydroxymelatonin (6-OHM) is a naturally-occurring, endogenous, major active metabolite of the neurotransmitter melatonin.^[1] Similar to melatonin, 6-OHM is a full agonist of the MT₁ and MT₂ receptors.^[2][3] It is also an antioxidant and neuroprotective, and is even more potent in this regard relative to melatonin.^[4][5]
