by humans. Along with calcium and phosphorous, it is an important constituent part of
bones and teeth. People obtain their requirements of magnesium from food like whole
grain cereals, nuts, legume, and green leafy
vegetables.

Deficiency of magnesium leads to health
problems like hyper-excitability, muscle weakness and fatigue. Severe and extended
magnesium deficiency can also lead to more serious consequences like death fro heart

levels.

Magnesium deficieny can be cured generally by
dietary supplements. However in severe cases intravenous injection of magnesium may be
