Understanding different calcium supplement options
Calcium is a vital mineral essential for numerous bodily functions. It plays a key role in blood clotting, as well as supporting the health of the heart, nerves, and muscles. Adequate calcium intake is crucial for strengthening bones and preventing osteoporosis. Factors like smoking, certain medications, sedentary lifestyles, or excessive alcohol can lead to calcium deficiency, increasing osteoporosis risk. Supplementing with calcium helps maintain optimal bone density and overall health.
