Magnesium plays an important role in regulating the neuromuscular activity of the heart. Where calcium stimulates the muscles, magnesium is used to relax the muscles. It aids the formation of bone and teeth and assists the absorption of calcium and potassium.

It also assists the parathyroid gland to process vitamin D, and a shortage here can cause absorption problems with calcium.
