If you do not eat any foods high in magnesium then take the RDA dose.
Many people can get by using 1/2 the RDA...or 200mg a day, of elemental magnesium. I explain elemental on that link.
Magnesium can be depleted by many drugs as well, including alcohol, and caffeine and other diuretic drugs. It is lost in diabetics daily also in the urine. Poor stomach acid may prevent magnesium from being absorbed from food.
