Calcium is critical for building and maintaining strong bones and preventing osteoporosis. Calcium is also needed for the proper functioning of nerves, muscles, glands, and the cardiovascular system. Some people don't get enough calcium and can benefit from calcium supplements. At the same time, certain people may be increasing their risk of heart attack and kidney stones by taking too much calcium from supplements. And some people may be using products that are not properly made.
 
Out of 15 calcium supplements recently purchased by ConsumerLab.com, 4 failed quality testing: Two popular products failed to properly break apart in disintegration testing -- meaning that you may not be getting the full benefits; another product was contaminated with lead above the level permitted without a warning label in California; and a widely-sold, candy-like combination supplement contained much more vitamin D than listed on the label -- 82% more!
