Magnesium is important for many reasons. It helps certain enzymes to function in the body, and is important in the production of proteins. It aids in the functioning of muscles. Magnesium is also important in the production and transport of energy in the body. It is found in nuts, peas, beans, grains, fruits and vegetables. Lack of magnesium causes sleepiness, hyperexcitability and muscle weakness although it is not common. Symptoms of magnesium deficiency also include anorexia, muscle twitching, apathy, heart changes. numbness, delirium, muscle contractions. Poor memory  and rapid heartbeat may also be symptoms of  magnesium deficiency. Too much is not usually a problem, as the body removes excess magnesium.

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.

Magnesium has a very important role to play in our body. It is the fourth most abundant mineral in our bodies. 50% of this is found in the bones and the most of the remaining is in the cells of the organs in the body.

Hundreds of different processes in the body require magnesium. These include muscle and nerve functions, the proper functioning of the heart, working of the immune system and the growth and repair of bones. Magnesium also regulates blood sugar levels, blood pressure and is essential for metabolism and synthesis of protein. Several roles of magnesium in controlling ailments like diabetes, heart disease and high blood pressure have also been found.
