description | Vitamin D supplementation may be used to lower oxidative stress. This interventional study aimed to investigate the effects of vitamin D supplementation on glutathione peroxidase 1 (GPx1) levels and other parameters in Arab adults with prediabetes. A total of 203 Saudi adults with prediabetes and vitamin D deficiency [intervention group, <i>N</i> = 146 (53 males and 93 females); control group, <i>N</i> = 57 (25 males and 32 females)] were included in this non-randomized, six-month intervention study. The intervention group received 50,000 international units (IU) cholecalciferol tablets once a week for two months, then twice a month for the next two months, followed by 1000 IU daily for the last two months. The control group received no supplementation. Serum 25(OH)D, lipid profile, glucose, C-reactive protein (CRP) and GPx1 were measured at baseline and after six months. Post-intervention, GPx1 concentrations increased significantly in the intervention group [17.3 (11.5−59.0) vs 26.7 (11.4−59.9) <i>p</i> < 0.01] while no changes were observed in the control group (<i>p</i> = 0.15). This significant increase in 25(OH)D and GPx1 levels persisted after adjusting for age and BMI. Stratification according to sex revealed that this favourable increase in GPx1 was true only for males (<i>p</i> = 0.002). In all groups, baseline GPx1 was inversely correlated with low density lipoprotein (LDL)-cholesterol (<i>r</i> = −0.26, <i>p</i> < 0.01) and body mass index (BMI) (<i>r</i> = −0.20, <i>p</i> < 0.05), while positively correlated with age (<i>r</i> = 0.18, <i>p</i> < 0.05) and systolic blood pressure (<i>r</i> = 0.19, <i>p</i> < 0.05). In conclusion, vitamin D supplementation favourably enhanced GPx1 levels in adult Arabs with prediabetes, particularly in males. |
