D3 1000 IU (25 mcg)
Mason Natural D3 1000 IU (25 mcg) is a vitamin supplement providing a single ingredient, Vitamin D3. This product contains 25 mcg (1000 IU) of Vitamin D3 per serving. Research suggests that for many adults, this dosage may be underdosed for achieving optimal Vitamin D levels, especially for those with deficiencies. With an N+ Score of 40 and a grade of 'F', this product falls into the below-average tier due to its ingredient adequacy score of 0, indicating the primary ingredient is not at a clinically effective dose for general adult support. The label transparency is 100%, but the formula completeness is 50% as it's a single-ingredient product. This product might be suitable for individuals seeking a very low dose of Vitamin D3, potentially as a minor top-up to existing intake, rather than for addressing significant deficiencies.
