Intervention was carried out for 12 weeks. Materials and Methods: In this triple-blind randomized controlled trial, 90 college students with serum 25(OH)D levels < 30 ng/ml were divided into three major groups of 30 to receive vitamin D 3 supplements of either 50000 IU/month and 1000 IU/day or placebos.
