ADVICE

Fix Sleep Hygiene First

  • Do optimize sleep hygiene first before trying supplements.
  • Use supplements only after addressing light exposure, bedtime routine, and stress management.
ADVICE

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.
INSIGHT

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.
