Objectives: Resveratrol (RES) is well documented for its multiple health benefits, with a notable impact on cancer prevention and therapy. This study aimed to evaluate the effect of RES supplementation on oxidative stress in patients with head and neck cancer (HNC) receiving home enteral nutrition (HEN). Methods: This randomized, single-center, open-label study involved 72 adult patients, with 40 completing the intervention. Participants in the intervention group received 400 mg of liposomal RES daily for 12 weeks alongside HEN, while the control group received HEN only. Body composition and oxidative stress markers—including total antioxidant capacity (TAC), malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPx), and reduced glutathione (GSH)—were measured at baseline and after 12 weeks. Results: Significant increases in TAC and SOD activity were observed in both groups. GPx activity increased significantly only in the RES group. MDA levels rose in both groups but were more pronounced in the RES group. GSH levels showed no significant changes. Phase angle (PhA) increased significantly in the RES group, while no significant change was observed in the control group. Conclusions: RES supplementation may enhance antioxidant defenses, as evidenced by increased GPx activity and improvements in TAC and SOD levels, supporting oxidative balance in patients with HNC receiving HEN. The higher MDA levels in the RES group may reflect RES’s dual antioxidant and pro-oxidant activities. Additionally, the observed increase in PhA suggests potential cellular health benefits. These findings highlight the potential of RES as a complementary antioxidant intervention in clinical oncology, warranting further investigation to clarify its therapeutic effects on oxidative stress and cellular health in cancer care.
