Calcium is essential — it supports bone density, muscle function, and more. Many seniors take calcium supplements (often with vitamin D) to help maintain strong bones and reduce fracture risk. However, observational studies and reviews have raised questions about supplemental calcium and cardiovascular health, especially in postmenopausal women and adults over 60.
Some analyses suggest that calcium from pills may contribute to higher coronary artery calcium scores in certain people, which doctors use as a marker for plaque buildup. One review of randomized trials found an association with increased cardiovascular events in healthy postmenopausal women taking supplements. Other research points to possible effects on blood vessels when large amounts are taken at once, as the body may deposit the mineral differently than when it comes gradually from diet.
It’s important to note the nuance: dietary calcium from foods like leafy greens, dairy, or fortified items generally does not show the same associations. The concern centers more on isolated high-dose supplements.
But calcium isn’t the only one under discussion. Here are other common supplements that deserve careful attention in seniors:
