Calcium 500 mg with D3 Adult Gummies
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.
