Vitamin D3 1000 IU
Bluebonnet's Vitamin D3 1000 IU is a single-ingredient vitamin supplement. Each softgel delivers 25 mcg (1000 IU) of Vitamin D3. This dosage is often considered underdosed for individuals with significant Vitamin D deficiency or for achieving certain health benefits, as clinical research frequently explores higher daily intakes. The product achieved an N+ Score of 40, earning an 'F' grade, which signifies a below-average quality assessment. Its strength lies in its simplicity and clear label, with only one active ingredient. This supplement may be appropriate for those seeking a very low-dose Vitamin D3 option or as a foundational supplement, but higher doses may be needed for therapeutic effects.
