Melatonin Benefits

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

NR Benefits

  • boosts NAD+ levels
  • supports DNA repair
  • supports mitochondrial energy metabolism
  • may improve insulin sensitivity

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

NR Dosing

250-1000 mg/day orally|single or divided doses|often taken in the morning

Melatonin Side Effects

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

NR Side Effects

  • nausea
  • GI discomfort
  • flushing uncommon

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.

NR

NR has substantial human and animal research showing reliable NAD+ elevation after oral dosing. Clinical outcomes are still being defined, but it is one of the better-studied longevity-related compounds.
