How to Choose Calcium
Calcium forms differ in elemental amount, serving size, and how they are taken. Compare elemental calcium per serving and consider dietary calcium before adding a supplement.
More calcium is not automatically better. Calcium can interact with medications and other minerals, and needs vary by age and health status. Seek professional guidance for diagnosed bone loss, kidney stones or kidney disease, pregnancy, medication use, or high-dose supplementation.
