Melatonin vs Orexin Antagonists (Suvorexant, Lemborexant)
Both are used for sleep better. Here's how they compare on human evidence, mechanism, safety and availability — in plain English.
| Melatonin | Orexin Antagonists (Suvorexant, Lemborexant) | |
|---|---|---|
| Human evidence | ★★★★★ | ★★★★☆ |
| Legal status | OTC Supplement, Prescription | Prescription |
| How it works | Pineal hormone binding MT1/MT2 receptors (MTNR1A/MTNR1B) in the suprachiasmatic nucleus — shifts the circadian clock rather than sedating. Most people massively overdose it. | Dual orexin receptor antagonists (HCRTR1/2) — block the wake-promoting orexin system rather than sedating with GABA, preserving natural sleep architecture. |
| In plain English | The "it's night" hormone. It re-times your body clock, so it's best for jet lag and late sleep phase, not as a sledgehammer sedative. 0.5 mg works as well as 10 mg with less morning fog. | Instead of knocking you out, they switch off the brain's "stay awake" signal — a cleaner, less-dependent modern sleep drug than Ambien. |
| Bottom line | Overused at 10–20× the effective dose. Start at 0.5 mg. | The modern, lower-dependence prescription sleep class. |
| Availability | Prescription only | Prescription only |
