    Melatonin for Antioxidant Protection

    Melatonin is itself an antioxidant and stimulates antioxidant enzymes, but this is a secondary benefit — its primary, validated role is circadian regulation.

    Overview

    Melatonin is itself an antioxidant and stimulates antioxidant enzymes, but this is a secondary benefit — its primary, validated role is circadian regulation.

    Verdict

    Mixed evidence

    Take it for sleep timing, not as an antioxidant strategy.

    How It Works

    Melatonin scavenges free radicals directly and upregulates glutathione peroxidase and SOD. Mitochondrial melatonin concentrations are among the highest in the body.

    Dosing & Protocol

    Typical dose

    Recommended dose
    0.5-10 mg/day melatonin for sleep; antioxidant studies have used far higher doses of 20-100 mg/day in clinical settings
    Expected timeframe
    N/A for antioxidant effects

    Protocol

    dose
    0.5-3 mg (sleep-dosing range)
    timing
    1-2 hours before target bedtime
    duration
    As needed

    Evidence

    What the studies say

    In-vitro and animal antioxidant data are robust, but human trials at typical sleep doses (0.5-3 mg) show inconsistent effects on oxidative stress biomarkers. Higher doses used in research contexts lack long-term safety data.

    No studies are yet linked to both Melatonin and Antioxidant Protection.

    Safety

    Caveats

    More is not better — high doses cause grogginess and vivid dreams. If antioxidant support is the goal, diet and CoQ10/NAC have stronger human data.

    Less likely to help if

    Healthy people seeking general antioxidant protection - the effect is unproven at ordinary doses.
