Melatonin

Q: What are the active compounds in Melatonin?

Melatonin (N-acetyl-5-methoxytryptamine) contains Melatonin. *These statements have not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.

Q: Do I need to cycle Melatonin?

Yes. Melatonin runs on a 3d on / 4d off schedule. Exogenous melatonin activates MT1 and MT2 receptors in the suprachiasmatic nucleus (SCN). Even at low doses (0.3–0.5 mg), nightly use can downregulate MT1/MT2 receptor density and suppress the pineal gland's endogenous melatonin synthesis via negative feedback on the AANAT enzyme. Four nights off allows MT1/MT2 receptor density to recover and AANAT enzyme activity to re-engage, maintaining robust endogenous melatonin production so you don't become dependent on exogenous dosing.

N-acetyl-5-methoxytryptamine

The body's natural sleep hormone, produced by the pineal gland in response to darkness. Melatonin regulates the circadian rhythm and signals to the body that it's time to sleep.

№ 01Signals the body to prepare for sleep*
№ 02Supports healthy circadian rhythm*
№ 03Helps reduce time to fall asleep*

Protocol & dosing

Exogenous melatonin can suppress endogenous production. Breaks preserve pineal sensitivity.

Recommended Protocol

3d on / 4d off

Rest days keep receptors fresh so every active day hits full strength.

Cycling threshold: Melatonin · ≥3mg / daymedium
Daily dose: 1 capsule evening
Half-life (t½): ~40–60 minutes

Why it cycles

Exogenous melatonin activates MT1 and MT2 receptors in the suprachiasmatic nucleus (SCN). Even at low doses (0.3–0.5 mg), nightly use can downregulate MT1/MT2 receptor density and suppress the pineal gland's endogenous melatonin synthesis via negative feedback on the AANAT enzyme.

Driver: MT1/MT2 receptor density / AANAT enzyme feedback suppression

Off-period: Four nights off allows MT1/MT2 receptor density to recover and AANAT enzyme activity to re-engage, maintaining robust endogenous melatonin production so you don't become dependent on exogenous dosing.

What the research shows.

2 citations

“Meta-analysis of 19 RCTs (n=1,683) examining melatonin for primary sleep disorders. Melatonin significantly reduced sleep onset latency by 7.06 minutes (p<0.001), increased total sleep time by 8.25 minutes (p=0.013), and improved overall sleep quality (p<0.001) versus placebo. Higher doses and longer durations showed greater effects.”Ferracioli-Oda et al., PLoS ONE, 2013

“Dose-response meta-analysis of 26 RCTs (n=1,689) optimizing melatonin as a sleep-promoting agent. Sleep onset latency reduction and total sleep time increase peaked at 4 mg/day. Administration 3 hours before desired bedtime was significantly more effective than the standard 30-minute pre-bedtime dosing (p=0.023).”Scarpelli et al., Journal of Pineal Research, 2024
