Rapamycin Benefits

  • mTOR inhibition
  • autophagy activation
  • cellular senescence modulation
  • lifespan extension in model organisms

Melatonin Benefits

  • Sleep regulation, circadian rhythm restoration, antioxidant protection, immune system support, potential neuroprotection, anti-aging effects

Rapamycin Dosing

0.5-6 mg oral weekly in studies|intermittent dosing protocols|clinical monitoring for tolerability

Melatonin Dosing

0.5-10mg orally, typically 30-60 minutes before desired sleep time. Lower doses (0.5-3mg) often more effective for sleep onset

Rapamycin Side Effects

  • mouth ulcers
  • elevated lipids
  • immunosuppression
  • glucose intolerance

Melatonin Side Effects

  • Drowsiness, headache, dizziness, nausea, vivid dreams, potential hormone interactions, daytime fatigue with higher doses

Research Overview

Rapamycin

Rapamycin extends lifespan in multiple model organisms and is a cornerstone compound in longevity biology. Human studies focus on immune function, inflammation, and age-related biomarkers rather than proven lifespan extension.

Melatonin

Melatonin has extensive clinical research supporting its efficacy for sleep disorders, jet lag, and shift work sleep disorder. Emerging research investigates its potential anti-aging, neuroprotective, and immune-modulating properties with promising preliminary results.
