Key Information About Different Calcium Supplements
Calcium is a vital mineral crucial for numerous bodily functions. It plays a significant role in blood clotting and supports the proper operation of the heart, nerves, and muscles. Maintaining adequate calcium levels is essential for healthy bones and preventing conditions like osteoporosis. Deficiency may occur due to smoking, medication, lack of exercise, or excess alcohol. Increasing calcium intake helps preserve bone density and overall health.
