Too much calcium can put women at
risk for kidney stones, among other health problems, say researchers from the
North American Menopause Society (NAMS).
Women close to menopause are
commonly told to take supplements containing calcium and vitamin D to prevent
diseases such as osteoporosis, to which they are particularly prone.
"I would recommend that
women determine how much calcium they typically get through their food sources
before taking a hefty calcium supplement. They may not need as much as they
think," says NAMS executive director, Margery Gass,
Dean, M.D., N.D., magnesium expert and advisory board member of the
Nutritional Magnesium Association, at www.nutritionalmagnesium.org, explains:
"When people consume too much calcium without sufficient magnesium, not
only will it create stress within the body but the excess calcium will not be
utilized correctly and may become toxic, because magnesium is essential for the
absorption and metabolism of calcium and vitamin D.
"Too much calcium and too
little magnesium can cause some forms of arthritis, kidney stones, osteoporosis
and calcification of the arteries, leading to heart attack and cardiovascular
Oz adds, "Women with osteoporosis are often seriously short on
magnesium, which makes up 1 percent of the minerals in bone. That may sound
piddlin', but if you don't have enough magnesium, bone crystals enlarge, making
your bones more brittle and prone to fractures."
