Understanding the Importance of Magnesium

Magnesium is an essential mineral involved in over 300 biochemical reactions in the body. It plays a crucial role in maintaining healthy nerve and muscle function, regulating blood sugar levels, and supporting a steady heart rhythm. However, not all magnesium supplements are created equal. The mineral is always bound to another substance, and this combination dictates its absorption rate (bioavailability) and its primary effects on the body. Understanding these differences is key to choosing the most effective supplement.
