Effect of Vitamin D Supplementation on Oxidative Stress Biomarkers in Women Following Religious or Intermittent Fasting Patterns
In conclusion, sixteen weeks of vitamin D supplementation in women adhering to Orthodox fasting produced no consistent improvements in oxidative stress markers. While a small reduction in TBARS was observed, this effect was modest and appeared indirect, being more closely associated with decreases in body weight and fat mass than with vitamin D status itself. Taken together, our findings indicate an overall neutral impact of vitamin D on redox balance, suggesting that any antioxidant benefit is likely secondary to metabolic or adiposity-related changes.
