An open-label interventional study on efficacy and safety of 25 µg of daily calcifediol capsule versus 100 µg of cholecalciferol sachets in apparently healthy volunteers.

ABSTRACT: Despite the multiple advantages of 25-hydroxyvitamin D (calcifediol or 25(OH)D) compared to cholecalciferol, it is used sparingly. This study was planned to assess the safety and efficacy of supplementing daily 25 µg of calcifediol capsules vis-a-vis 100 µg (4000 IU) of cholecalciferol sachets in apparently healthy individuals with vitamin D deficiency in Chandigarh, India (latitude 30.7° North, 76.8° East). It was a prospective, interventional study to evaluate the effects of calcifediol vis-a-vis cholecalciferol. Following initial screening of 70 subjects in each group, 62 were included in the calcifediol and 41 in the cholecalciferol group. Forty-six from calcifediol and 37 from cholecalciferol group completed the 6-month follow up. There was a significant increase in serum 25(OH)D (355
