Scope To investigate the effects of postoperative parenteral nutrition (PN) with multivitamins supplementation on oxidative stress and metabolism. Methods and results The participants are randomly assigned in a 1:1 ratio to groups: total nutrient admixture (TNA) + multivitamin ( n = 14, Group A) and TNA + normal saline ( n = 16, Group B). The levels of blood vitamins, ILs, and MDA are assessed and the dysregulation of metabolism is analyzed using nontargeted metabolite profiling. The degree of postoperative stress in Group A is significantly lower than that in Group B by analyzing changes in the levels of IL‐8 and MDA. A set of 43 features are qualified to have a variable importance parameter score of >1.5 of a partial least‐squares discriminate analysis model and fold change of >1.5 at p ‐value <0.05 between Groups A and B. The principal metabolic alternations in Group A include increased tricarboxylic acid cycle and ketogenesis with reduced plasma‐free amino acids. Backing the results of clinical biomarkers, increased levels of antioxidative molecules, together with decreased levels of inflammatory related polyunsaturated fatty acids, are observed. Conclusion Postoperative PN enhanced by multivitamins can alleviate traumatic stress and improve metabolic transition from catabolism to anabolism in gastric cancer patients.
