The effect of Nutrition Bio-shield superfood (NBS) on disease severity and laboratory biomarkers in patients with COVID-19: A randomized clinical trial
RCT 70 hospitalized severe COVID-19 patients in Iran, showing lower mortality and improved clinical markers with treatment combining vitamins A, B1–B3, B5, B6, B9, C, D, K, and magnesium, potassium, phosphorus, sulfur, manganese, calcium, iron, boron, copper, zinc, omega-3, omega-6, and omega-9. The median age was lower in the treatment group 49 (29–77) vs. 55 (29–81).

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 mea
surement 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 treat
ment process of COVID-19 disease.
