Oxidative stress, particularly when precipitated by the intake of a diet rich in fats, has the potential to induce an inflammatory state. Therefore, it is crucial to consider the administration of agents possessing antioxidant and anti-inflammatory properties for the benefit of these patients. The objective of this study was to investigate the ability of postbiotic and paraprobiotic substances to regulate oxidative stress and inflammation. We hypothesized that both postbiotics and paraprobiotics could demonstrated significant efficacy in reducing oxidative stress and inflammation, with distinct differences in their effectiveness.
