Based on preliminary data, Mg appears to be effective against tender point pain when used at high doses and in combination with malic acid.Based on currently available studies, Mg is a reasonable addition or an alternative to other known drug therapies in subgroups of FM patients that have low magnesium levels or receive high doses of B1.In addition, based on short-term studies, Mg seems to be effective in relieving well-known symptoms of FM and safe with only minimal and infrequent side effects. Further clinical trials with long-term analyses need to be performed to confirm preliminary findings”It is best to take magnesium with food and it is best to take with calcium and Vitamin D. Ensure you have enough vitamin Bs in your diet as Bs are necessary for proper magnesium usage and most people with FM can be low in vitamin B’s due to stress. If you find you are experiencing the laxative effect with a type of magnesium then try another type that you may be able to digest better. The magnesium most recommended for FM is magnesium malate (naturally found in such things as apples). Another option is magnesium is liquid form. The recommended dosage is 300-750 mg daily, but due to the difficulties one might have with digestion it is recommended to start off slow and increase the dosage over time as you find comfortable.
