A plain-language, continually updated guide from Dr. Matt Chalmers’ clinical reference on hormones and peptides.
Melatonin is produced by your pineal gland in response to darkness and governs sleep onset, antioxidant capacity, cellular cleanup (autophagy), and the nighttime pulse of growth hormone your body releases during deep sleep. Melatonin decline is considered one of the earliest measurable biomarkers of biological aging — its levels start falling well before many other, more commonly discussed age-related hormone changes show up.
This is exactly why sleep quality is one of the pillars of our overall approach to hormone and metabolic health: restoring healthy melatonin rhythm has downstream effects on your entire hormone system, not just how easily you fall asleep.
Melatonin is synthesized from the amino acid tryptophan, through serotonin as an intermediate step — adequate dietary tryptophan and the B vitamins involved in this conversion pathway (particularly B6) are relevant to the body’s natural melatonin production.
Melatonin is available as an over-the-counter dietary supplement in the U.S. Some of our peptide protocols, including Epitalon, are studied for their association with restoring nocturnal melatonin secretion — see that page for more detail.
Melatonin’s documented physiological role is regulating the sleep-wake cycle in response to darkness. It’s available over-the-counter in the U.S., and its decline is considered one of the earliest measurable biomarkers of biological aging — which is part of why restoring healthy melatonin rhythm is treated as a priority in our overall approach to hormone and metabolic health.
Light exposure patterns (especially blue light in the evening) and adequate dietary tryptophan (melatonin’s precursor, as noted above) are the most relevant factors.
