A double-blind trial by the same research group using 300 mg magnesium and 1,200 mg malic acid per day found no reduction in symptoms, however.2 Though these researchers claimed that magnesium and malic acid appeared to have some effect at higher levels (up to 600 mg magnesium and 2,400 mg malic acid), the positive effects were not demonstrated under blinded study conditions. Therefore, the evidence supporting the use of these supplements for people with fibromyalgia remains weak and inconclusive.
