Background: Chronic fatigue syndrome (CFS) is a disorder of unknown etiology, consisting
of prolonged, debilitating fatigue, and a multitude of symptoms including neurocognitive
dysfunction, flu-like symptoms, myalgia, muscle weakness, arthralgia, low-grade fever,
sore throat, headache, sleep disturbances, and swelling and tenderness of lymph nodes. No
effective treatment for CFS is known.
Objective: The purpose of the study was to evaluate the efficacy of the reduced form of
nicotinamide adenine dinucleotide (NADH) administered orally in a randomized,
double-blind, placebo-control, crossover study in patients with CFS. NADH is known to
trigger energy production through ATP generation, which may form the basis of its
potential effects. The study drug is ENADA® NADH the only stabilized absorbable oral form
of NADH a nutritional supplement product.
Methods: Twenty-six evaluatable patients who fulfilled the CDC criteria for CFS completed
the study. Medical history, physical examination, laboratory studies and questionnaire
were obtained at baseline, 4, 8 and 12 weeks. Subjects were randomly assigned to receive
either 10 mg of NADH (ENADA®) or placebo at week 0 for a four-week period, followed by a
four-week wash-out period, followed by a final four-week period in which subjects were
crossed to an alternative regimen.
Results: No adverse effects were observed related to the study drug. Within this cohort of
twenty-six patients, four times more patients responded to NADH (ENADA®) compared to
Conclusion: Collectively, the results of this preliminary study indicate that NADH
(ENADA®) may be an effective therapy in the management of the Chronic Fatigue Syndrome
and suggest that further clinical trials be performed to establish its efficacy in this
clinically perplexing disorder.
