Many Americans take Calcium supplements because they worry that they are not getting enough to keep our bones strong, as they age.

But according to a major new study, we may not need supplements after all.

The Institute of Medicine has found that most of us are getting sufficient amounts of both Vitamin D and Calcium through our diets by consuming milk, cheese, and fish.

In fact, through the study, experts found going well above the recommended levels for Vitamin-D and Calcium could lead to kidney and heart damage.

While you may think a supplement couldn't hurt, think again.

Experts say you can have too much of a good thing.

Catharine Ross, Ph.D., who serves as the committee chair for the Institute of Medicine, says "We have no evidence, no scientific evidence that more than these recommended dietary allowances is better, so why would you go above it?”

However, a recent study by the Cleveland Clinic showed most people in Northern Ohio did not have enough Vitamin D and needed supplements.

As always, check with your doctor before beginning any kind of vitamin regiment.
