60The purpose of this study is to evaluate the effects of oral melatonin plus zinc supplementation in relieving self-reported fatigue in CFS/ME
Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) is a complex medical condition, characterized by severe disabling fatigue with no known cause, no established diagnostic tests, and no universally effective treatment. No studies have evaluated symptomatic treatment using oral melatonin plus zinc supplementation in CFS/ME. The primary endpoint was to assess the effect of melatonin plus zinc supplementation on self-reported fatigue. Secondary measures included self-reported outcomes of sleep problems, anxiety/depression, dysautonomia, QoL and side-effects during treatment.
Melatonin 1 mg plus Zinc 10 mg o.d. 1 hour before going to bed during 16 weeks
Isomaltose o.d. 1 hour before going to bed during 16 weeks
