The coronavirus disease 2019 (COVID-19) pandemic has seriously threatened public health worldwide. Nutritional supplements may have a positive influence on the recovery of patients with viral infection. This study aimed to assess the influence of oral nutritional supplements (ONSs) on the biochemical parameters of elderly patients with mild-to-moderate COVID-19.
This clinical trial will be conducted on 145 elderly patients with mild-to-moderate COVID-19. Patients in the intervention group (n=74) received nutritional powder (vitamins, minerals, dietary fiber, polyphenols, omega-3, amino acids, and probiotics) for 14 days. Cases in the control group (n=71) took the placebo, except for nutritional powder, and they received the same treatment. Biochemical parameters were measured before and two weeks after intervention.

After 14 days, patients in the groups will be measured by C-reactive protein (CRP), creatinine (Cr), blood urea nitrogen (BUN), and interleukin-8 (IL-8) ,white blood cell (WBC), red blood cell (RBC), platelet (PLT), neutrophil percentage (NE%), prothrombin time (PT), D-Dimer (DD), blood glucose, sodium (Na+), potassium (K+), aspartate aminotransferase (AST), glutamate pyruvic transaminase (ALT), albumin, calcium (Ca), arterial blood gas (ABG) parameters, and interleukin-10 (IL-10).
