Calcium 500 mg with D3 Adult Gummies by Kirkland Signature is an 'Other Combinations' supplement designed to provide calcium and vitamin D. This product received an N+ Score of 58, earning it an 'F' grade, indicating areas for improvement in its formulation. It contains 5 ingredients, with Calcium at 500mg meeting a clinically studied dosage. However, both Vitamin D at 25mcg (1000 IU) and Phosphorus are present at underdosed levels, which may limit their efficacy. The product offers 100% label transparency, which is a positive, but its ingredient adequacy is low at 33% and formula completeness at 25%. This supplement may appeal to those seeking a convenient form of calcium, while noting the underdosed co-factors.
