Melatonin
Best-in-class: Melaton-3
The body's darkness/sleep-timing hormone. Best understood as a circadian signal — not a sedative.
How Melatonin actually works
Melatonin is a timing signal, not a sedative. The pineal gland releases it when light stops hitting the retina, and it binds MT1 and MT2 receptors in the suprachiasmatic nucleus — the master clock — where MT1 damps the wake-promoting signal and MT2 shifts the phase of the clock itself. Which direction it shifts depends entirely on timing relative to your own rhythm, not on dose. Physiological release is small; typical supplement doses are many times higher than the body ever produces, which saturates the receptors without improving the signal.
Melatonin quick facts
| Suggested dose | 0.5–3 mg 30–60 min before bed; use the lowest effective dose. |
| How often | Daily, or only on disrupted nights |
| Who it's for | Jet lag, shift work, delayed sleep timing, and older adults with low output. |

✅ Clinically validated
- Meta-analyses show it shortens time to fall asleep and helps reset circadian rhythm (jet lag, shift work, delayed sleep phase).
- Low doses are effective; more is not better for sleep onset.
📊 Correlative data
- Endogenous melatonin declines with age, tracking with more fragmented sleep.
🧪 Theoretical / extrapolated benefits
- Antioxidant and longevity roles are actively researched but separate from — and less established than — its circadian sleep effect.
These tiers tell you how much human evidence exists — not how well something works. This is the research space, and most of what’s in here is new rather than disproven. Something sitting at “theoretical” usually means nobody has funded the trial, not that the trial was run and failed.
The trap runs the other way too: something can be clinically validated and still do very little for you specifically. A statistically significant result in a study population is not a promise about your body.
- ✅ Clinically validated — human randomised trials or meta-analyses support it. The strongest footing available.
- 📊 Correlative — observational or epidemiological data. Suggestive, and genuinely useful for direction, but it cannot establish cause.
- 🧪 Theoretical / mechanistic — the mechanism is understood and often demonstrated in cells or animals, and the human trial doesn’t exist yet. Unproven is not the same as ineffective. Plenty of what’s standard practice today sat here five years ago.
✗ is a safety flag, not a grade. Where you see it, the concern is harm — not a disappointing trial. A compound tested for one purpose and found not to help there can still be worth studying somewhere else, so a negative result never gets rendered as a cross. It sits alongside the tier, because something can be both well-studied and genuinely risky.
My job is to tell you which one you’re looking at, and let you make the call. Grading something low isn’t me dismissing it — it’s me refusing to oversell it. This is the research space, and being able to reason forward from a mechanism matters as much as waiting for the trial.
Almost everyone takes far too much, far too late. Doses in the range of a few tenths of a milligram to one milligram match physiology and work as well or better than ten milligrams for sleep onset — the high-dose versions mostly buy grogginess the next morning. For jet lag or a delayed body clock, the timing is the active ingredient: taken several hours before your target bedtime it advances the clock, taken in the morning it delays it. It's not habit-forming, but it also isn't a treatment for insomnia caused by anything other than mistimed rhythm.
Melatonin — safety & side effects
- Morning grogginess is the commonest complaint and almost always means the dose is too high. Physiological doses are 0.3–1 mg; most products sell 3–10 mg. Vivid dreams and headache are also dose-related.
- Independent assays have repeatedly found melatonin products containing anywhere from 17% to 478% of the labelled dose, and some containing serotonin. Buy from a vendor that tests.
- Interacts with warfarin, immunosuppressants, diabetes medication and fluvoxamine (which dramatically raises melatonin levels). Additive with sedatives.
- Timing matters more than dose — taken at the wrong hour it shifts your rhythm the wrong way. Caution with autoimmune disease.
