Melatonin Timing Calculator

Determine the optimal time and dosage for taking melatonin supplements based on your specific needs and circumstances.

Important Melatonin Facts

  • Melatonin is a hormone naturally produced by the pineal gland that helps regulate sleep-wake cycles.
  • Blood levels of melatonin rise 1-5 times above physiological peak about an hour after taking 0.1-0.5 mg doses.
  • Higher doses (1-5 mg) can elevate blood levels 10-100 times above normal nighttime peak levels.
  • Melatonin levels typically return to baseline 4-8 hours after supplementation.
  • The most common side effects of melatonin supplementation include headaches, dizziness, nausea, and drowsiness.
  • Natural melatonin production decreases with age, which is why older adults may benefit from supplementation.
  • Melatonin supplements are available over-the-counter in the US but are prescription-only in many other countries.
  • Some medications, including beta-blockers, can interfere with natural melatonin production.
  • Melatonin should be used with caution by those who are pregnant, breastfeeding, or have autoimmune disorders.
  • The long-term effects of regular melatonin supplementation are still not fully understood.

Factors Affecting Melatonin Effectiveness

Factor Description
Light Exposure Blue light from screens can suppress natural melatonin production. Avoid screens and bright lights 1-2 hours before bed.
Timing Taking melatonin at the wrong time can disrupt your circadian rhythm rather than help it.
Dosage More isn’t always better. Sometimes lower doses (0.3-0.5 mg) are more effective than higher doses.
Food Interactions Taking melatonin with food, especially high-fat meals, may delay its absorption and effect.
Individual Metabolism Liver function and individual metabolism can affect how quickly melatonin is processed in your body.
Age Children, adults, and seniors may require different dosages for optimal effectiveness.
Caffeine & Alcohol Both can interfere with melatonin’s effectiveness and should be avoided close to bedtime.
Medication Interactions Melatonin can interact with blood thinners, immunosuppressants, diabetes medications, and birth control pills.
Supplement Quality The FDA doesn’t regulate melatonin supplements, so quality and actual content can vary between brands.
Health Conditions Certain health conditions like depression, dementia, and seizure disorders may affect how melatonin works in your body.

Age-Specific Melatonin Recommendations

Age Group Generally Effective Dosage Range Special Considerations
Children 0.1 to 3 mg Should only be used under healthcare provider supervision. May be helpful for certain sleep disorders.
Adolescents 3 to 12 mg May experience more delayed sleep phase disorders. Should discuss with healthcare providers.
Adults 1 to 25 mg Start with the lowest effective dose (0.5-3 mg) and increase as needed. Most adults don’t need high doses.
Older Adults 1 to 6 mg May be more sensitive to side effects. Natural melatonin production decreases with age.

Note: Always consult with a healthcare provider before starting melatonin supplementation, especially for children, pregnant women, or if you have existing health conditions.
