Calcium citrate is more easily absorbed, especially on an empty stomach, making it a great choice for older men or those with digestive concerns. Calcium carbonate is more concentrated and often less expensive, but it requires stomach acid for absorption and is best taken with meals.

Added Nutrients: Vitamin D3 and K2
Vitamin D3 helps your body absorb calcium, while vitamin K2 directs calcium to your bones rather than soft tissues. Many top calcium supplements for men include these synergistic nutrients. Look for products that combine calcium with at least 1000 IU of vitamin D3 and a meaningful amount of K2 for optimal bone and cardiovascular support.
