Calcium 600 mg + D3 200 IU
Major Calcium 600 mg + D3 200 IU is a single vitamin and mineral supplement designed to support bone health. It contains 600 mg of Calcium, which is at a clinically studied dosage, and 200 IU of Vitamin D3. However, research suggests that 200 IU of Vitamin D3 is significantly underdosed for most adults seeking bone support, potentially limiting its effectiveness for calcium absorption compared to higher doses. This product has an N+ Score of 55, earning a grade of F, primarily due to the underdosed Vitamin D3 and a low formula completeness score, despite transparent labeling of its two ingredients. It may be suitable for individuals looking for a basic calcium supplement, but those seeking comprehensive bone support with adequate Vitamin D3 may need to consider additional supplementation.
