    NADH for Chronic Fatigue Syndrome (ME/CFS)

    One small randomized trial found that 10-20 mg/day of stabilized NADH reduced chronic fatigue syndrome symptom severity compared with placebo, and NADH is mechanistically plausible given the mitochondrial dysfunction reported in ME/CFS. However, this remains a single small trial awaiting replication.

    Overview

    One small randomized trial found that 10-20 mg/day of stabilized NADH reduced chronic fatigue syndrome symptom severity compared with placebo, and NADH is mechanistically plausible given the mitochondrial dysfunction reported in ME/CFS. However, this remains a single small trial awaiting replication.

    Verdict

    Mixed evidence

    How It Works

    NADH is the primary electron donor to mitochondrial Complex I, directly supporting ATP production. Mitochondrial and redox dysfunction are documented features of ME/CFS, giving supplementation a plausible (though unproven) mechanistic basis.

    Dosing & Protocol

    Typical dose

    Recommended dose
    10-20 mg stabilised NADH daily, taken on an empty stomach in the morning
    Expected timeframe
    4-12 weeks

    Protocol

    form
    Enteric-coated stabilised NADH - unprotected NADH degrades in stomach acid
    duration
    8-12 weeks
    co factor
    Take on an empty stomach and not in the evening, since it can be activating. Evidence is mixed: small trials report modest fatigue-score improvement, but the studies are short and largely industry-supported. Pacing remains the core of management.
    titration
    Increase to 20 mg daily after four weeks if there is no response; some CFS trials combined 20 mg NADH with 200 mg coenzyme Q10
    starting dose
    10 mg on rising, at least 30 minutes before food

    Evidence

    What the studies say

    The evidence rests on one randomized, double-blind crossover trial (Forsyth et al., 1999) in 26 CFS patients, where 10 mg/day NADH for 4 weeks produced a favorable response in 31% of patients versus 8% on placebo. A follow-up trial combining NADH with CoQ10 reported reduced fatigue and improved biochemical markers. Both studies are small and short; no large modern replication exists. Formulation stability (enteric coating, blister packs) is critical since NADH degrades rapidly.

    Safety

    Caveats

    Improved energy must not be spent exceeding the activity envelope - overexertion causes post-exertional crashes. Reported effects include jitteriness, insomnia if taken late, and loss of appetite. Safety ceiling: doses above 20 mg/day have not been evaluated. No pregnancy or breastfeeding safety data - avoid. Exclude anaemia, thyroid disease, sleep apnoea and coeliac disease before attributing fatigue to CFS.

    Less likely to help if

    People whose fatigue has an untreated medical cause, and those with severe ME/CFS in whom the trials showed little change.
