Joint & BoneServing: 1 Tablet(s)Type: Single Vitamin and Mineral

Sundown Naturals Calcium 500 mg Plus Vitamin D is a single vitamin and mineral supplement targeting joint and bone health. Each tablet provides 500mg of Calcium, which is considered a clinically studied dose for bone support. However, the accompanying 125 IU of Vitamin D is underdosed for optimal absorption and bone health benefits, as higher doses are often recommended. The product has an N+ Score of 55, earning an F grade, primarily due to the insufficient Vitamin D dosage. With only two ingredients, it offers excellent label transparency. This supplement may be beneficial for those prioritizing Calcium intake, but additional Vitamin D may be required for comprehensive support.
