>Calcium makes me feel slightly ill and my joints are stiff and unhappy. Magnesium makes my body purr.
I don't think I'm up to "purr" yet, but I sure do feel better since I've started taking it and no calcium. :)
Haven't had a bone density test either, but I think it's indicative of our having been lead down the garden path somewhat on the calcium thing that the countries who get the most calcium have the higher fracture rates!

REPORT FROM THE
HARVARD SCHOOL OF PUBLIC HEALTH NUTRITION ROUNDTABLE
Section 3: Calcium: Too Much of a Good Thing?A number of studies have been done to examine the relationship between calcium and bones. A study by Mark Hegsted, Professor Emeritus of Nutrition at the Harvard School of Public Health, compared the rates of calcium intake to the risk of hip fracture by country. Surprisingly, he found that countries with low intakes of calcium actually had lower rates of hip fracture and countries with high intakes of calcium had higher rates of fracture.
More recent studies have looked at the relationship between calcium and bone density ... except for a small, one-time benefit, higher daily intake of calcium did not appreciably strengthen bones.
Close to home, the Nurse's Health Study revealed information about the relationship between milk consumption and rates of fracture. Investigator Diane Feskanich looked at patterns of milk consumption from 1980 to 1992 and found that the nurses who drank milk regularly did not have lower rates of fracture than nurses who did not drink milk. ...
Calcium intake also poses important health questions for men. Some evidence suggests that high calcium intake may increase the risk of prostate cancer. Recent studies have shown that in countries where the consumption of milk is highest, such as Scandinavia and North America, rates of prostate cancer are also high. By contrast, in the Asian countries where per capita milk consumption is low, the rates of prostate cancer are low. Furthermore, a summary of studies of prostate cancer shows a repeated association between consumption of dairy products and an elevated risk of developing prostate cancer. For example, in one study consuming two glasses of milk per day was associated with a 50% greater risk. Is the calcium in milk solely responsible for the rise in risk? A recent study looked at rates of calcium intake from 500 (about one and one half glasses of milk per day) to 2000 milligrams in men sixty-eight years of age or younger. For men who ingested the highest amounts of calcium, the risk of developing metastatic prostate cancer was threefold that of those who ingested the lower amounts. For men over the age of sixty-eight, the higher rate of calcium intake resulted in a sevenfold increase in risk. How could calcium raise the probability of developing prostate cancer? It is possible that it acts by depressing circulating levels of vitamin D which has cancer inhibiting properties. ...
