Can you get too much calcium? Yes.

Since bones tend to deteriorate with age, it makes sense to take in more calcium as we get older, to help lower the risk of fractures in our hips and limbs. But how much additional calcium is enough? And is there such as thing as too much?

Yes, says Eva Warensjo, a researcher at Uppsala University in Sweden, who reports this week in the British Medical Journal that excessive calcium may actually cause, rather than prevent fractures….

The data suggest that current U.S. recommendations for calcium intake — at least 1,200 mg daily for women over age 50 to prevent fractures — may be too high. The guidelines represent the best available data linking calcium to bone health and reduced fracture risk, particularly in postmenopausal women, who are less able to build enough bone to keep up with skeletal deterioration. But scientists have been debating how valid this advice may be, since baseline levels of calcium at menopause tend to vary widely depending on women's ethnic backgrounds, socioeconomic status and lifestyle.

The article clarifies that women have different needs for calcium based on their diet and exercise habits, as well as their personal physiology, but that the recommended amount of calcium in the US is probably too high for most women, and it may be lowered to 700-800 mg daily.

Consult with your health care professional before changing your supplements. And… (because we are who we are) (1) EAT MORE LEAFY GREENS, (2) DO WEIGHT-BEARING EXERCISE (like walking), and (3) QUIT SMOKING. Those things are in your control and can help improve your bone health.
