En conclusion

Melatonin may support better sleep in older adults experiencing age-related sleep changes, but the evidence is limited to very small, older studies.

  • All 3 studies show positive effects, but only 30 total participants
  • Includes 1 RCT specifically on melatonin for age-related insomnia
  • Studies are over 20 years old (1999-2001) — newer research is needed
  • Natural melatonin production declines with age, which supports the rationale for supplementation
