Melatonin Benefits

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

Fisetin Benefits

  • senolytic activity
  • reduces inflammatory signaling
  • supports mitochondrial function
  • may improve healthspan

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

Fisetin Dosing

1000-2000 mg/day orally|1-2 days per month in senolytic-style studies|take with a fat-containing meal

Melatonin Side Effects

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

Fisetin Side Effects

  • GI upset
  • headache
  • possible blood-thinner interaction

Research Overview

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.

Fisetin

Preclinical studies show fisetin can selectively target senescent cells and reduce age-related inflammatory markers. Early human research exists, but definitive anti-aging outcomes in humans are still unproven.
