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 [PDF]
Journal of Nutritional ScienceDespite 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
