Overview

Nutricost Calcium Carbonate provides 1000mg of calcium carbonate per 2-capsule serving, yielding 400mg of elemental calcium (40% of the 1000mg is elemental calcium — calcium carbonate has the highest elemental calcium percentage of any calcium form). Calcium carbonate is the most common and cost-effective form of calcium supplementation. It requires stomach acid for absorption, so it should be taken with meals. The 240-capsule count provides 120 servings (4-month supply). For optimal absorption, calcium should be taken in divided doses of 500mg or less, paired with vitamin D3 and vitamin K2.
