Magnesium Helps Allergies

"And magnesium deficienly would explain a lot of what happened to me when my health went haywire. I now take about 250% of the RDA for magnesium (approx. 675 mg. elemental magnesiuim) per day, and some calcium, though I don't always make the RDA there. So many things have improved. The dust mite allergies have receded noticeably, the seasonal pollen allergies are pretty much gone, the tooth grinding is better."
