Calcium Supplements To Keep You Living Longer

Oyster Shell Calcium

Oyster shell calcium is often advertised as a more natural form of calcium with a higher absorbable content of calcium. However, oyster shell calcium is difficult to have quality control over, and many supplements may contain high levels of lead toxins, which are extremely dangerous especially to children. Long-term exposure to lead may result in problems with the nervous and reproductive systems, the kidneys, and the liver. It can also cause permanent brain problems. The Global Healing Center recommends avoiding this type of calcium.
