When something is said to be chelated, this means it is bonded to something else.

More Info: Magnesium in supplements has often been chelated with one or more amino acids. This helps your body to absorb the mineral more efficiently. The magnesium is absorbed through the intestinal wall, as an amino acid would be.

What Is Magnesium? 

Magnesium is a mineral that is essential for the human body to remain healthy. Magnesium is needed by each of the body's organs, especially the kidneys and muscles (including the heart). A high percentage of the magnesium in an adult human is used to build teeth and bones. Magnesium plays a role in over three hundred metabolic processes that take place in the body. Magnesium helps activate enzymes, create proteins, produce energy, and regulate the levels of numerous other vital nutrients and minerals. It is also key to a healthy nervous system and vascular system.

Signs of Magnesium Deficiency 

Although magnesium deficiency is rare, there are some signs to watch out for. Symptoms of magnesium deficiency can include confusion, irritability, anxiety, decreased appetite, depression, cramps, tingling, numbness, arrhythmia (irregular heartbeats), sleep disorders, and seizures. Some possible causes of magnesium deficiencies are vomiting or diarrhea, gastrointestinal diseases, diabetes, hyperthyroidism, kidney disease, too much coffee or other diuretics, alcohol consumption, and a heavy menstrual cycle.
