Thanks Birdy, I think it was in relation to the bioavailability and helping with reflux primarily that I decided at the time to go with it.
Citrate might sound familiar too—consider it an erudite way of saying that it's derived from citric acid (in this case, magnesium salt is obtained from the citrus acid). With excellent bioavailability—that is, the efficacy with which a substance is absorbed and used by the body—it's no wonder magnesium citrate one of the most highly recommended magnesium supplements by health professionals. Often used to naturally support digestion—specifically, to alleviate constipation and acid indigestion—it's also, bonus points, easy on the wallet. However, it may lead to dehydration (and the imbalance of minerals that arrives with this), in that it pulls water into the intestines.
