73–78% of adults with ADHD have delayed sleep-wake cycles with melatonin onset ~90 minutes later than controls. This isn't just comorbidity — emerging evidence frames ADHD as partly a circadian rhythm disorder. The Delphi consensus protocol: 0.5mg immediate-release melatonin taken 3 hours before habitual sleep onset, advancing by 1 hour weekly for 3–4 weeks. Counterintuitively, stimulant medications may improve (not worsen) sleep quality by reducing pre-sleep rumination.

For women unwilling or unable to use HRT, a targeted nutraceutical stack — anchored by magnesium bisglycinate, omega-3 fatty acids, and vitamin D3+K2 — offers moderate evidence for reducing vasomotor symptoms, improving sleep quality, and stabilizing mood during the menopausal transition. Maca (Lepidium meyenii) shows promising evidence for FSH/LH modulation and hot flash reduction, particularly in early postmenopausal women. DIM (diindolylmethane) may support favorable estrogen metabolism ratios but direct symptom evidence remains limited; it requires caution in women with estrogen-sensitive conditions. No supplement replaces HRT for severe vasomotor symptoms — be honest about that limit.

The strongest evidence-based sleep supplement stack centers on four compounds: Magnesium glycinate (300–400 mg, 60–90 min before bed) modulates GABA and lowers cortisol for deeper NREM; Glycine (3 g, 30–60 min before bed) reduces core body temperature via NMDA receptors in the SCN, shortening sleep latency and improving slow-wave sleep; L-Theanine (100–200 mg, 30–60 min before bed) induces alpha-wave activity for calm, non-sedating relaxation; and low-dose Melatonin (0.3–0.5 mg, 90–120 min before bed) resets circadian timing without grogginess. Apigenin (50 mg from chamomile extract) is a reasonable addition for anxiolytic GABA-A modulation, though most RCT evidence is for chamomile extract rather than isolated apigenin. Use this stack for sleep onset + deep sleep quality; morning refresh comes primarily from consistent sleep timing and avoiding high-dose melatonin.
