The Side Effects on the Stomach of Calcium & Vitamin D
Calcium and vitamin D are two nutrients that the body uses to keep your bones healthy and strong. Calcium supplements often contain vitamin D because this type of vitamin helps the body absorb calcium more efficiently. If you have low calcium or vitamin D levels, your doctor may recommend treatment with a supplement that contains these nutrients. The side effects of calcium and vitamin D on your stomach may be uncomfortable; you should discuss them with a medical professional if they persist.
