This study aimed to investigate the effects of L-Taurine, L-Glycine, L-Arginine, Daidzein, Proanthocyanidin, Vitamin B1 and Vitamin B6 on decreasing fibromyalgia induced symptoms. We conducted a randomized, double-blind, placebo-controlled study on 142 patients aged 32-81 years old diagnosed with fibromyalgia. The participants were randomized to receive tablets containing L-Taurine (10 mg/day), L-Glycine (10 mg/day), L-Arginine (7 mg/day), Proanthocyanidin (5 mg/day), Daidzein (3 mg/day), Vitamin B6 (1 mg/day) and Vitamin B1 (0,5mg/day) or a placebo for 16 weeks. After 16 weeks, 94% (n=67) of participiants reported a significant reduction of fibromyalgia induced symptoms. However in the placebo group only 10% (n=7) of participants reported a significant reduction of fibromyalgia induced symptoms.
