Yes, calcium supplements can cause harm.

Calcium is an essential mineral and an average average adult body contains more than 2 pounds of calcium.

Calcium is very essential not only for bone health but also for good functioning of many organs.

Too little calcium is bad but too much of calcium is also harmful.

Because calcium supplements are freely sold in Supermarkets and Pharmacies, many people assume they are absolutely safe.

A study published in Heart journal suggests that calcium supplements has the potential to damage heart valves.

The study also found that “Oral calcium supplementation with or without vitamin D is associated with lower survival”.

The results obviously need to be confirmed by other studies.

In the meantime, anyone with good amount of calcium in their routine diet need to think carefully about risk versus benefits of calcium supplements before taking them.
