Melatonin

Hormone that regulates the sleep-wake cycle; effective for circadian-rhythm issues (jet lag, shift work) more than as a general sleep aid for everyone.

CategorySupplements / Vitamins
Typical routeOral
Half-life~40-60 minutes
Common dose range0.5-3 mg, 30-60 min before bed (lower doses are often as effective as higher ones)
Typical cycle lengthAs needed or short-term use

BioHack Track models Melatonin at a half-life of 0.8 hours, so every dose you log is decayed against that curve and the app shows what is still circulating — not just what you typed.

Reconstitution

Oral tablet, gummy, or sublingual; no reconstitution needed.

Storage

Store at room temperature, away from light.

Cautions

Can cause grogginess at higher doses; effects on long-term natural melatonin production with nightly high-dose use are not well studied.

Track Melatonin in BioHack Track. Half-life, dose range and route come pre-filled from this library — log a dose and the app counts your vial down, models what is in your system, and puts it on the same chart as your labs and body composition.
