In general, malic acid is believed to help prevent a lack of oxygen in the muscle tissues, a condition known as hypoxia. As mentioned, malic acid is crucial in the Krebs cycle responsible for converting food into energy. Hence, it ensures that muscle tissues receive adequate amount of oxygen to produce sufficient energy for muscle cells for proper functioning.
According to the Journal of Nutritional Medicine, increase intake of malic acid through food sources or supplements, has been found to help decrease muscle pain and soreness in those suffering from fibromyalgia and chronic fatigue syndrome (CFS). It was also observed more pain relief is received when patients consume magnesium supplements with malic acid. Some patients suffering from fibromyalgia experienced pain relief within 2 days of taking malic acid supplements.
Malic acid is also observed to elevate energy levels in people suffering from fibromyalgia and CFS According to a study in the Journal of Rheumatology malic acid was found to aid in the production of adenosine triphosphate (ATP), an vital element in intracellular energy transfer (People who experience chronic fatigue usually lack ATP in their bodies). Hence, malic acid can bring about an improvement in fatigue in fibromyalgia and CFS.
Increased Tolerance in Exercising
Fibromyalgia and CFS patients lack exercise or have trouble exercising because they tend to get tired easily. Malic acid is found to increase muscular performance and increase tolerance to exercise. This enable fibromyalgia and CFS patients to exercise more efficiently.
