What it is
A melatonin supplement offered in a lower everyday amount and a higher amount. Most people know melatonin as the hormone the body releases as darkness falls -- a timing signal that helps realign a drifted sleep-wake rhythm rather than sedating you. But that is only half of it: melatonin is also one of the body's own antioxidants, made and concentrated right inside the mitochondria, the cell's power plants. Because our own production falls steeply with age, the offering spans a low everyday dose and a higher one.
Why the evidence supports it
Melatonin is one of the most heavily studied molecules in science, and its familiar roles -- shortening the time to fall asleep and shifting a clock that has drifted with travel or late-night light -- are only the surface. The deeper, far-less-marketed story is that melatonin is a mitochondrial antioxidant: it is produced and concentrated inside the mitochondria themselves, it helps protect their membranes from oxidative wear, and it works as part of a team rather than alone, helping regenerate vitamins C and E back toward their active forms. Since the body's own output declines markedly with age, topping up that signal is a structure/function rationale that reaches well past sleep. Its safety record is also unusually clean: melatonin has no established lethal dose and is well tolerated across a wide range in the research, which is why both a low everyday amount and a higher one are offered. Kept honest, it supports the Mind's Regulate function -- the night-time timing signal -- and the cell's own antioxidant defenses in the mitochondria; it is not a sedative, and not a treatment for any condition.
What it supports
- Supports your natural circadian (sleep-wake) timing
- Acts as a mitochondrial antioxidant, supporting the cell's own defenses
- Helps regenerate vitamins C and E as part of the antioxidant network
- Tops up a signal the body produces less of with age
Which function it supports
Ties to the Mind's Regulate function and the cell's antioxidant defense -- melatonin is both the body's own circadian messenger and a mitochondrial antioxidant, so it supports the timing of your sleep-wake cycle and the cell's protection from oxidative wear.

These are lab markers where this product's ingredients have measured evidence in our citation library. This is not a claim that the product will change your results -- the research attaches to the ingredient, and what a marker means depends on the whole picture.

- Cortisolsolid evidence
via Melatonin · 36 studies, 13 in people
What people often notice when this marker sits outside the usual range
Higher: "Wired but tired" -- exhausted all day, then alert the moment the head hits the pillow.
Lower: Profound fatigue that is worst in the morning, and improves slightly through the day -- the reverse of the usual pattern.
- Hemoglobin A1c (HbA1c)emerging evidence
via Melatonin · 4 studies, 4 in people
What people often notice when this marker sits outside the usual range
Higher: Everything listed under fasting glucose, but with more time behind it -- HbA1c is a three-month average, so symptoms are usually established rather than new.
- Glucose (Fasting)mixed evidence
via Melatonin · 9 studies, 3 in people
GRADE-assessed evidence on blood glycaemic indices in adults.
What people often notice when this marker sits outside the usual range
Higher: Waking at 3am, often with a racing heart -- 'why do i wake up at 3am every night'.
Lower: Shakiness, sweating, sudden anxiety and difficulty concentrating that resolve within minutes of eating.
Lab results are interpreted by a qualified clinician who knows your history. Nothing here diagnoses anything or replaces that conversation.
No product works in isolation
Every cell function above -- Sense, Exchange, Transform, Build, Maintain, Adapt -- needs the same broad base of optimal micronutrient levels running underneath it, all the time. Melatonin is not a stand-alone fix; it is one piece that plugs into that larger system. The foundation comes first, and this supports it.

Foundational, or targeted?
Not everything in the shop is meant to be taken forever. Some products here are foundational -- a daily nutrient base built for long-term, ongoing use. Others are targeted -- shorter-term support for a specific season, not a lifelong habit. If you are not sure which one this is, that is a fair question to ask us before you buy.

Take it about 30-60 minutes before the bedtime you are aiming for, in a dark-ish room so the signal lands. Start with the lower amount and see how you respond. The higher-dose option is a personal choice worth discussing with your provider first rather than assuming more is better.

Melatonin is offered in a lower everyday amount and a higher amount. Melatonin is the signal your body already uses to mark nighttime, so a small dose can help nudge your sleep timing when your rhythm has drifted. It fits people whose sleep clock is off from travel or late screens.
FAQ
What does Melatonin support?
It supports your natural circadian (sleep-wake) timing, an easier drift into sleep at night, and the body's own nighttime antioxidant activity, and it helps when travel or late screens have shifted your rhythm.
How do I take it?
Take it about 30 to 60 minutes before the bedtime you are aiming for, in a dark-ish room so the signal lands. Start with the lower amount and see how you respond.
What makes it different?
It is used the way the body actually uses it -- as a timing signal, not a sedative. Starting low to find the smallest amount that helps is better than assuming more is better.
