Magnesium malate is used to treat fibromyalgia and chronic fatigue syndrome, according to About.com. This substance is made of magnesium, which helps new cells form, and malic acid. Magnesium also helps to maintain bones, nerves and muscles.
Though many doctors and patients claim magnesium malate can ease symptoms of fibromyalgia and chronic fatigue syndrome, research doesn't support the claims as of 2015, explains About.com. However, more research needs to be done.
The proper dosing of magnesium malate is 140 milligrams of magnesium two times a day and 600 milligrams of malic acid three times a day, claims About.com. However, some studies found that less may be just as effective, so patients are urged to work with a doctor to find the proper dosage. Patients may also get magnesium and malic acid from food. For instance, magnesium is found in foods such as artichokes, fish, black beans and almonds. Malic acid is found in apples.
Malic acid and magnesium may both cause intestinal issues, states About.com. Those who develop issues such as diarrhea, intestinal cramping or bloating may want to stop taking these supplements to find out if the symptoms disappear. It is also possible that one or the other may cause these issues. In this case, it is advisable for the individual to find out which one is causing the distress and only take the other.
