WHITE PLAINS, NY — JUNE 15, 2005 — has released its latest report on the quality of magnesium supplements sold in the U.S. In addition to being an essential mineral, magnesium may help prevent migraine headaches, menstrual pain, PMS, and leg cramps during pregnancy. found two products to contain approximately 2 micrograms of lead per daily dose — more than the amount permitted in California without a warning label. Nineteen other products passed the testing by meeting the standard for lead contamination, containing their claimed amounts of magnesium, and, if tablets or caplets, breaking apart properly for delivery in the body.

"It is well known that lead exposure should be minimized," said Tod Cooperman, M.D., president of "Pregnant women, in particular, should be advised to use magnesium supplements that are low in lead, because lead crosses the placenta and magnesium is taken during pregnancy to reduce leg cramping." He added, "With current manufacturing techniques there is no reason for a magnesium supplement to contain the amount of lead found in these two products."
