Magnesium is a mineral found in various locations of the
body including bones, muscles, and intracellular fluids. Dietary sources of magnesium
include fruits, green vegetables, fish, and whole grains. The stomach absorbs
approximately one third of the magnesium consumed.
The
major function of magnesium is helping to regulate neuromuscular activity. It helps
nerves communicate with other structures and also helps muscle tissue contract normally.
It also helps repair DNA that is damaged. Additionally, protein synthesis is aided by
proper amounts of magnesium.
Dietary deficiencies of
magnesium can lead to a whole host of problems including irritability of nerve and
muscle tissue (especially the heart) which leads to disturbances in the normal
electrical stimulation of the myocardium. These disturbances can lead to cardiac
arrhythmia's.
