Background/Objectives: The prevalence of depression and anxiety symptoms is remarkably high in malnourished individuals undergoing hemodialysis. The goal of this project was to evaluate the impact of administering an oral nutritional supplement combined with a probiotic blend on the microbiota, intestinal permeability, and depression symptoms in malnourished hemodialysis patients. Methods: With this aim, a randomized trial was conducted with three parallel groups: a control group with individualized diet, a supplement–placebo (SU-PL) group with oral nutritional supplementation (ONS), and a supplement–probiotic (SU-PR) group with ONS in conjunction with a probiotic blend. Blood and fecal samples were collected at basal time, and at 3 and 6 months. Several blood biomarkers, like zonulin, lipopolysaccharide-binding protein (LBP), lipopolysaccharide (LPS), and brain-derived neurotrophic factor (BDNF), were measured, and the fecal microbiome was sequenced with the Illumina platform. The Hospital Anxiety and Depression Scale (HADS) was used for the estimation of depression (HADS-D) and anxiety (HADS-A) symptoms, along with the standardized mental health index SF12-MH from the general health questionnaire SF-12. Results: The results showed that patients who consumed the probiotic blend maintained the LPS levels from their baseline readings and decreased their BDNF levels compared to the SU-PL or control groups. Moreover, a significant decrease in HADS-D scores (less depressive symptoms) and an increase in SF12-MH scores (higher quality of life) were found in that group in comparison to the other groups. The intervention produced an impact on the microbiome population, where the SU-PR group had reduced Akkermansia abundance with respect to the other groups, while their Acidaminococcus abundance decreased and their Barnesiella abundance increased with respect to the SU-PL group. Conclusions: Overall, the results indicate that the probiotic with the nutritional supplement could reduce the intestinal permeability biomarkers and improve depressive symptoms and quality of life in malnourished hemodialysis patients.
