17th treatment shown to reduce risk in March 2021
*, now known with p = 0.0000013 from 26 studies.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.
4,100+ studies for 60+ treatments.
80 patient RCT with 40 patients treated with a comprehensive regimen of nutritional support, showing significantly lower mortality with treatment. Treatment contained cholecalciferol, vitamin C, zinc, spirulina maxima, folic acid, glutamine, vegetable protein, selenium, resveratrol, omega-3 fatty acids, l-arginine, magnesium, probiotics, and B-complex IV. Adherence was strictly monitored.
The immune effects of probiotics are strain-specific.
This study is excluded in the after exclusion results of meta analysis: combined treatments may contribute more to the effect seen.
Study covers vitamin B9, vitamin D, probiotics, zinc, and vitamin C.

Effect of a Nutritional Support System to Increase Survival and Reduce Mortality in Patients with COVID-19 in Stage III and Comorbidities: A Blinded Randomized Controlled Clinical Trial

The COVID-19 evolution depends on immunological capacity. The global hospital mortality rate is 15-20%, but in México it is 46%. There are several therapeutic protocols, however, integral nutrition is not considered. In this study, a Nutritional Support System (NSS) was employed to increase survival and reduce mortality in patients with stage III COVID-19. A randomized, blinded, controlled clinical trial was performed. Eighty patients (aged 30 to 75 years, both sexes) were assigned to (1) "Control Group" (CG) hospital diet and medical treatment or (2) "Intervention Group" (IG) hospital diet, medical treatment, and the NSS (vitamins, minerals, fiber, omega-3, amino acids, Bcomplex, and probiotics). IG significantly increased survival and reduced mortality compared to CG (p = 0.027). IG decreased progression to Mechanical Ventilation Assistance (MVA) by 10%, reduced the intubation period by 15 days, and increased survival in intubated patients by 38% compared to CG. IG showed improvement compared to CG in decrease in supplemental oxygen (p = 0.014), the qSOFA test (p = 0.040), constipation (p = 0.014), the PHQ-9 test (p = 0.003), and in the follow-up, saturation with oxygen (p = 0.030). The NSS increases survival and decreases mortality in patients with stage III COVID-19.
