Magnesium is vital to the metabolism of carbohydrates, proteins and fats and activates more than three hundred different body enzymes, particularly those that require three b vitamins; thiamin (vitamin b1), riboflavin (vitamin b2) and pyridoxine (vitamin b6), vitamins c and e. It also helps fight tooth decay by binding calcium to tooth enamel.
Deficiency of magnesium can result in muscular weakness, twitching, convulsions, nausea, vomiting and runaway heartbeat.
