Supplementation with saffron helps improve antioxidant status. Oxidative stress plays an important role in ulcerative colitis (UC). The present study aimed to investigate the effect of saffron supplementation on disease severity and Oxidative/Antioxidant factors in patients with UC. This randomized double‐blinded study was conducted on 80 mild to moderate UC patients. Participants were randomly divided into intervention (100 mg saffron/daily) and placebo (100 mg maltodextrin/daily) groups. Of all the participants, 75 completed the study. After 8 weeks, there were significantly increased in the mean score of simple clinical colitis activity index questionnaire (3.83 ± 1.78 to 3 ± 1.60, p = .004), the serum levels of total antioxidant capacity (2.68 ± 0.90 to 2.79 ± 0.87, p = .016), superoxide dismutase (60.69 ± 9.59 to 66.30 ± 10.79, p = .009) and glutathione peroxidase (22.05 ± 14.27 to 29.67 ± 17.97, p = .011) in patients received saffron compared to the placebo group. Whereas, there was no significant difference in serum levels of malondialdehyde between the two groups. Finally, dietary saffron as an alternative therapy may effective in improving antioxidant factors and reducing the severity of disease in UC patients.
