Too much Calcium = Increased risk of Cardiovascular Disease

A new study published in the Annals of Internal Medicine tracked more than 36,000 women who took placebo or 1000mg Calcium carbonate and 400IU Vitamin D daily over 22 years.

They found a 7% reduction in cancer mortality in those women who supplemented with calcium and vitamin D when compared with those who took placebo. They also found a 6% increase in cardiovascular disease mortality.

Here’s my take: in the case of calcium, more is NOT better! Women are often advised to supplement with 1200mg calcium as they age or when they are found to have low bone density. I always stress that this 1200mg recommendation should come from FOOD AND SUPPLEMENTATION combined. If you eat a high calcium diet, there is no need to supplement. In fact, as this very large study shows, too much calcium can result in calcification of soft tissues such as breasts, artery linings, and kidneys.

Bottom line, aim to get calcium from your diet. If you need some additional help, supplement just enough to get to 800-1200mg total. Calcium supplements should always be taken with a meal.

(Incidentally, I believe the decline in cancer mortality can be attributed to the Vitamin D).
