About Calcium Carbonate, Calcitriol and Zinc
Calcium Carbonate, Calcitriol and Zinc is a nutritional supplement used to treat calcium and vitamin D deficiency and support overall bone health. It is commonly prescribed for osteoporosis, osteopenia, fracture recovery, muscle weakness, and increased calcium requirements in older adults and postmenopausal women.
Calcium carbonate supplies elemental calcium, which is essential for strong bones and teeth. Calcitriol, the active form of vitamin D, helps the body absorb calcium efficiently from the intestine and maintains normal calcium levels in the blood. Zinc supports bone formation, tissue repair, wound healing, and normal immune function.
Common side effects include constipation, diarrhea, stomach upset, abdominal pain, nausea, vomiting, bloating, and loss of appetite. Taking medicine after meals may help reduce stomach discomfort. Avoid taking more than the prescribed dose, as excessive calcium or vitamin D may increase the risk of high calcium levels in the blood.
