A comprehensive review on the impact of polyphenol supplementation and exercise on depression and brain function parameters

Abstract

Abstract The objective of this review study is to examine the combined antidepressant effects of exercise and polyphenol supplementation, with a focus on specific polyphenolic compounds such as crocin, curcumin, and quercetin, as well as different forms of physical exercise, including aerobic and resistance training. The research examines how these interventions influence depressive-like behaviors, cognitive function, and neurochemical markers in animal models and human participants. The findings demonstrate that both exercise and polyphenols independently contribute to mood enhancement, reduced anxiety, and improved cognitive function through mechanisms such as neurogenesis, neurotransmitter modulation, and anti-inflammatory effects. Notably, the combined interventions showed a synergistic effect, providing more significant benefits in reducing symptoms of depression and anxiety, enhancing cognitive performance, and supporting overall mental well-being. These results suggest that integrating exercise and polyphenol supplementation could be a promising non-pharmacological approach to managing depression and related disorders.
