Magnesium Test
Magnesium is a critical electrolyte that is necessary for proper muscle, nerve and enzyme function and is necessary for the body to make and use energy. It also assists in the movement of other electrolytes, such as sodium and potassium, into and out of cells. Low levels of magnesium are associated with cardiac arrhythmia.
The majority of magnesium in the body is found in bones and inside cells so the amount of magnesium in the blood is normally very small. Magnesium levels can be easily increased through supplements or diet. Foods that contain magnesium include whole grain products, leafy green vegetables, nuts and beans. Some studies have also found that consuming foods rich in magnesium reduces the risk of stroke.
