Magnesium is an essential mineral involved in hundreds of biochemical processes in the body.
It contributes to normal muscle and nerve function, energy production, and bone health.
Because magnesium is found in many foods, understanding dietary sources is an important first step.

These include:
-
Muscle contraction and relaxation

When evaluating supplements, consider:
