description NOW Foods Magnesium Oxide Overview

NOW Foods Magnesium Oxide is the most basic and affordable form of magnesium available. While it has the lowest bioavailability of all magnesium forms, it is still effective for those who need a simple, inexpensive way to boost their magnesium intake or for those who need a mild laxative effect. It is not the best choice for systemic absorption or muscle support, but it is a reliable, no-frills product for those on a very tight budget. It is a basic, entry-level supplement that serves a specific, limited purpose.
