Malic Acid is the principal acid contained in apples and many other fruits and vegetables. It supports energy production by allowing your body to produce ATP more efficiently, which is essential for proper muscle function. Leading healthcare professionals familiar with Fibromyalgia recommend Malic Acid, combined with Magnesium, for the chronic muscle soreness and fatigue experienced by most patients with this condition. Healthcare providers have found that patients with Fibromyalgia who use a combination of Malic Acid and Magnesium reported improvements in the reduction of muscle pain and tiredness. A study in the Journal of Nutritional Medicine suggests that the muscle pain and fatigue of Fibromyalgia are predominantly caused by the breakdown of muscle proteins due to a deficiency of oxygen and other substances needed for ATP production. Further, the study presented data supporting the critical role of Magnesium and Malic Acid in ATP production under low-oxygen conditions. Jorge Flechas, M.D., M.P.H., has participated in two medical studies that have tested to combination of Malic Acid and Magnesium for Fibromyalgia patients. In these studies, patients reported a significant reduction in pain and tenderness within 48 hours and without any side effects. In his practice, Flechas has used these combination supplements for six years on about 500 Fibromyalgia patients and states, â I have found the results are positive 90% of the timeâ . Research has found Malic Acid, combined with Magnesium, to be an effective dietary aid for Fibromyalgia.
