Episode notes
Fix Sleep Hygiene First
- Do optimize sleep hygiene first before trying supplements.
- Use supplements only after addressing light exposure, bedtime routine, and stress management.
Use Low-Dose Melatonin
- Try low-dose melatonin (0.3–1 mg) rather than high megadoses nightly.
- Keep doses conservative to avoid circadian disruption or morning drowsiness.
Tart Cherry Boosts Melatonin Pathway
- Tart cherry extract can nudge tryptophan toward serotonin and melatonin synthesis.
- That provides a gentler route to support endogenous sleep chemistry compared with high melatonin doses.
