Abstract
Since the beginning of COVID-19 pandemic, many Iranian people are taking 50.000 IU of vitamin D3 on the weekly or biweekly bases in order to enhance their immune system function. This cross- sectional study was conducted on the patients of endocrinology clinic to compare 25(OH)D levels of weekly or biweekly consumption with the monthly users of vitamin D3 50,000 IU. The level above 100ng/ml of 25(OH)D was defined as hypervitaminosis D. Totally, 211 patients (108 and 103 patients in monthly and weekly/ biweekly groups, respectively) were studied. In the subgroups of weekly and biweekly users, the rates of hypervitaminosis were 18.9% and 4.5%, respectively. In contrast, only 0.9% of monthly users had hypervitaminosis D. The highest vitamin D value of 185 ng/ml was detected in a patient who consumed 50,000 IU vitamin D3 weekly for 6 years. No hypercalcemia was detected in the patients with hypervitaminosis D.
