Melatonin Benefits

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

Urolithin A Benefits

  • mitophagy activation
  • muscle endurance support
  • mitochondrial health
  • cellular cleanup

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

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.

Urolithin A

Urolithin A has both animal and human data showing effects on mitochondrial biomarkers and physical performance-related endpoints. It is one of the more promising mitochondrial-targeted longevity compounds in current literature.
