| Estradiol / Menopausal HRT | Melatonin | |
|---|---|---|
| Human evidence | ★★★★★ | ★★★★★ |
| Legal status | Prescription | OTC Supplement, Prescription |
| How it works | Binds estrogen receptors (ESR1/ESR2) to restore bone density (RANKL suppression), vasomotor stability, and genitourinary tissue in menopause. Transdermal routes lower clot risk vs oral. | Pineal hormone binding MT1/MT2 receptors (MTNR1A/MTNR1B) in the suprachiasmatic nucleus — shifts the circadian clock rather than sedating. Most people massively overdose it. |
| In plain English | Replaces the estrogen that falls at menopause — the most effective treatment for hot flushes and bone loss. Modern transdermal forms are safer than the older pills. | 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. |
| Bottom line | Highly effective menopausal therapy; route matters for safety. | Overused at 10–20× the effective dose. Start at 0.5 mg. |
| Availability | Prescription only | Prescription only |
