Oyster Shell Calcium 500 mg with Vitamin D
About This Product
Major Oyster Shell Calcium with Vitamin D is a single vitamin and mineral supplement designed to support bone health. This product contains 500mg of Calcium, which is provided at a clinically studied dose, and 200 IU of Vitamin D3, which research suggests is underdosed for optimal support. With a total of two ingredients and 100% label transparency, the product's N+ Score is 55, earning it an 'F' grade, indicating significant areas for improvement, particularly in formula completeness and ingredient adequacy. This product may be suitable for individuals seeking a basic calcium supplement, though the low Vitamin D3 dosage might necessitate additional supplementation. The low N+ Score suggests it may not be the most comprehensive option available.
