What is magnesium?
Magnesium is the fourth most abundant mineral in your body right after calcium and phosphorous, a grayish metal, and the eighth most abundant element in the earth’s crust. Adults have about 25 grams of magnesium in their bodies. Almost all of it is stored in the bones, muscles, and soft tissues which is difficult for your body to access. There are many types of magnesium including magnesium carbonate, chloride, oxide, sulfate, aspartate, lactate and more. Regardless of the type, what is magnesium good for?

Magnesium is readily available but don’t just grab whatever you see. Magnesium glycinate, citrate, chloride, and carbonate are more easily absorbed than magnesium oxide and sulfate. But please note that magnesium citrate may cause stomach distress and magnesium in general may interact with other medications, so be sure to check with your healthcare provider regarding what’s right for you.
