Table 4: Comparison of 25(OH)D3 serum concentrations of men and women in the study group using and not using vitamin D supplements. 25(OH)D3 serum concentrationsare presented in mean ± SD. While no significant difference was observed comparing women and men using vitamin D supplements. Significantly higher 25(OH)D3concentrations were observed by comparing women to men who not using vitamin D supplements (P =0.026).
