What is the role of magnesium?
Magnesium has peculiar relationship with fluoride. Magnesium forms 0.05% of body weight and is essential for humans. Magnesium helps in elimination of fluoride from the body by competing with calcium. Daily requirement of magnesium is 350-500 milligrams. Fluorosis incidence is less in villages whole water content of magnesium is high compared to those with lower levels with similar fluoride in drinking waters. Adequate magnesium lessens the fluoride toxicity and vice versa. Hence fluoride supplementation should help in endemic regions.
