Previous studies have shown that hesperidin may have beneficial effects on depression; however, to the best of our knowledge, no clinical trial has yet been conducted in this area. The aim of the present study was, therefore, to determine the effects of hesperidin on depression, serum brain-derived neurotrophic factor (BDNF), and serum cortisol levels in post-coronary artery bypass graft (CABG) patients. Toward this goal, 73 post-CABG patients with depression symptoms were enrolled. The participants were randomly divided into two groups to receive either 200 mg/day hesperidin (n = 38) or placebo (n = 35) for 12 weeks. Depressive symptoms, serum BDNF, and cortisol levels were then assessed at the baseline and after intervention. Beck Depression Inventory-II (BDI-II) was also used to determine the severity of depression. Sixty-six patients completed the trial. Hesperidin decreased depression severity after 12 weeks, as compared to placebo (p = .004), but serum BDNF and cortisol were not statistically significantly different in the two groups after the intervention. Subgroup analyses also showed that, while in the patients with mild depression, the score of BDI-II was significantly different in the hesperidin and placebo groups after intervention; there was no difference in the severity of depression between the two groups in patients with moderate-to-severe depression. To conclude, a dose of 200 mg/day hesperidin may reduce depressive symptoms after 12 weeks in post-CABG patients with mild depression.
