NBS superfood: a promising adjunctive therapy in critically ill ICU patients with omicron variant of COVID-19.

This clinical trial aimed to assess the impact of Nutrition Bio-shield superfood (NBS) on clinical status among critically ill ICU patients suffering from acute respiratory distress syndrome (ARDS) due to the Omicron variant of COVID-19. A total of 400 patients with confirmed Omicron-related ARDS were randomly assigned to either the intervention group (n = 200) or the control group (n = 200). Patients in the intervention group received 1.5 g of NBS powder daily for 2 weeks in addition to standard antiviral treatment, while the control group received a placebo alongside standard antiviral therapy. Serum samples were collected from all patients in both groups, and various clinical and laboratory parameters, including ESR, CRP, D-Dimer, CPK, WBC count, lymphocyte count, and lymphocyte percentage, were measured using established methodologies. Following a 14-day intervention period, the intervention group exhibited a significant reduction in mean serum levels of CRP (15.39 vs. 48.49; P < 0.001), ESR (14.28 vs. 34.03; P < 0.001), D-Dimer (485.18 vs. 1009.13; P = 0.001), and CPK (68.93 vs. 131.48; P < 0.001) compared to the control group. Conversely, a significant increase was observed in the mean serum levels of lymphocytes (1537.06 vs. 1152.60; P < 0.001) in the intervention group after 14 days of treatment compared to the control group. The remarkable reduction in inflammatory markers and mortality rates observed with NBS supplementation alongside standard antiviral treatment underscores its crucial role in mitigating inflammation and achieving an important milestone in the fight against COVID-19.

The effect of Nutrition Bio-shield superfood (NBS) on disease severity and laboratory biomarkers in patients with COVID-19: A randomized clinical trial.

BACKGROUND: Nutrition Bio-shield Superfood (NBS) is an organic and viable herbal supplement that could improve the function of the immune system. The present study aims to determine the effect of NBS on disease severity and laboratory biomarkers in patients with COVID-19. METHODS: This current study was a randomized, comparative, parallel two-arm and single-blind clinical trial study performed in Tehran, Iran. In total, 70 patients with COVID-19 were included in the present study and assigned to two groups including 1) intervention group (n = 35) and 2) control group (n = 35). All patients included in the intervention group received 4.5 gr daily rate of NBS superfood, three times the daily rate of 1.5 gr for 14 days. In contrast, patients included in the control group received a placebo three times a day for 14 days. The measurement of laboratory parameters including CRP, ESR, D-Dimer, LDH, CPK, SGOT, SGPT, ALP, FBG, WBC count, PLT, and lymphocyte count was performed using standard kits and methods. Moreover, all serum samples were tested to determine the levels of IL-6 and TNF-ɑ using specific commercially available ELISA kits according to the instructions of the manufacturer. RESULTS: A significant decrease in the mean serum level of several variables including CRP (p < 0.001), ESR (p < 0.001), D- Dimer (p = 0.001), LDH (p < 0.001), SGOT (p = 0.002), SGPT (p = 0.019), ALP (p < 0.001), WBC count (p < 0.001), body temperature (p = 0.013), IL-6 (p < 0.001), and TNF-α (p < 0.001) was seen 14 days after intervention from baseline in the intervention group than control group. In contrast, in the intervention group, the significant increase from baseline of lymphocyte percentage (p < 0.001) and oxygen saturation (p < 0.001) was seen 14 days after receiving NBS superfood than the control group. CONCLUSION: Results showed that the use of NBS superfood had various beneficial effects on COVID-19 disease severity. These results suggest that NBS superfood can be used as an effective natural supplement in the treatment process of COVID-19 disease.

The effects of nutrition bio-shield superfood powder on immune system function: A clinical trial study among patients with COVID-19.

The present study aimed to evaluate the effects of Nutrition Bio-shield Superfood (NBS) powder on the immune system function and clinical manifestations in patients with COVID-19. We compare the effects of NBS powder on the immune system function and clinical manifestations among two different groups: 1) intervention group receiving standard treatment scheduled according to treatment guidelines plus NBS powder, and 2) control group receiving only the same standard treatment. The serum levels of IL-2, IL-6, IL-17, IFNγ, and TNFα were determined after four weeks of treatment by specific ELISA kits according to the manufacturer's instructions. Finally, the level of immune system stimulation and inflammatory markers were compared at baseline and after intervention in both groups. Data were analyzed using SPSS (version 22). A p-value of ≤ 0.05 was set as significant. A total of 47 patients with COVID-19 (24 patients in the intervention group and 23 patients in the control group) were included in this study. Results showed that the differences in the mean decrease of IL-2, IL-6, and TNF-α in the intervention group in comparison to the control group were 0.93, 10.28, and 8.11 pg/ml, respectively (P<0.001). On the other hand, there was no difference in IL-17, IFNγ, monocytes, eosinophil, and other inflammatory indices between the intervention and control groups. Although NBS powder was able to significantly decrease the levels of some proinflammatory cytokines in patients with COVID-19, however, it is noteworthy that the course of the disease was to large part unaffected by NBS power and there was a reduction independent of treatment. The present study indicates that NBS powder could provide a beneficial anti-inflammatory effect in patients with COVID-19. Hence, NBS in treating patients with COVID-19 shows promise as an adjuvant to the current standard antiviral treatment of such patients.
