Heather, I wouldn't know because I get my magnesium through malic acid/magnesium supplements and my multiple vitamin.
Here are other good doctors that say that malic acid and magnesium do help with fibro pain. There have been studies done on this, too. Besides, I know my pain improved a lot after trying these. But, as you know, what works for one won't work for another. Malic acid is found in apples.
In a report in the December 1999 issue of the Annals of Internal Medicine, The American College of Physicians & American Society of Internal Medicine listed malic acid among the treatments recommended for fibromyalgia pain. The report was entitled "Management of Fibromyalgia".

"Magnesium and malic acid are also critical. When malic acid and the other compounds are low, the body often has to shift to the very inefficient (anaerobic) means of generating energy. This contributes to the abnormal buildup of lactic acid that occurs after exercise in CFIDS/FM. This causes muscle achiness and fatigue", Dr. Jacob Teitelbaum, From Fatigued to Fantastic Newsletter and author of From Fatigued to Fantastic, A manual for Moving Beyond Chronic Fatigue and Fibromyalgia
Jorge Flechas, M.D., M.PH., a FM and CFIDS specialist from Hendersonville, NC strongly recommends the combination of malic acid and magnesium for fibromyalgia and has utilized the combination on nearly 500 FM patients. He has also participated in 2 clinical studies that have tested these ingredients on fibromyalgia patients. In the studies, patients reported a significant reduction in pain and tenderness within 48 hours of taking the supplements.
