A total of 575 medical students from different academic years participated in this study. Results: A total of 475 medical students participated in this survey. Most of them were Saudi citizens. There were no male-to-female differences. The vast majority of the study participants were in the intern year and only 1% were in the clinical year. Results showed that medical students seem to have substantial information regarding the value of vitamin D and vitamin D deficiency -related diseases and bone health. Furthermore, nationality was found to have a strong significant association with all domains of vitamin D benefits. Conclusion: A moderate awareness level was detected regarding the deficiency of vitamin D. Age, gender, nationality and academic grades were significant factors affecting the awareness level.
