Magnesium is very important - the body cannot function without it. Unfortunately, when taken orally, the magnesium can bind with other nutrients and render them un-absorbable...so I think it is best to take magnesium at least an hour apart from other supplements and medications for this reason. This info is from my Allergist, who was a chemical engineer before he became a doctor.
