Calcium Carbonate with Vitamin D 600mg

Calcium carbonate is the most concentrated and economical form of calcium, providing 600mg elemental calcium per tablet – 46% of daily value. It requires stomach acid for dissolution, so take with food. Each tablet also contains 400 IU vitamin D3 to improve calcium absorption from the gut and reduce parathyroid hormone-driven bone resorption. This combination is proven to slow bone loss in postmenopausal osteoporosis and reduce fracture risk by 15-20%. 200 tablets – three-month supply (two tablets daily). Take one tablet twice daily with meals. Do not exceed 2500mg total calcium daily from diet and supplements to avoid kidney stones and vascular calcification. Side effects: constipation, gas, bloating – increase water and fiber. Avoid taking within 2 hours of iron supplements or thyroid medication. Not for individuals with hypercalcemia or sarcoidosis. Non-GMO, gluten-free.
