The ability of a hen egg white bovine colostrum supplement to prevent severe COVID-19 was tested in a double-blind randomized control study. Methods: Adults with mild/moderate COVID-19, risk factors for severe disease, and within 5 days of symptom onset were assigned to the intervention (n = 77) or placebo (n = 79) arms. Symptoms were documented until day 42 post-enrollment and viral clearance was assessed at 11-13 days post-symptom onset. Results: One participant developed severe COVID-19. The severe-type symptom score was lower in the active arm at 11-13 days post-symptom onset (p = 0.049). Chest pain, fever/chills, joint pain/malaise, and sore throat were significantly less frequent in the active arm. No differences in viral clearance were observed. Conclusion: The intervention reduced symptoms of mild/moderate COVID-19. Clinical Trial Registration: DOH-27-062021-9191 (South African National Clinical Trials Register) Plain language summary: Natural proteins found in milk (lactoferrin) and egg white (ovotransferrin and lysozyme) could have therapeutic value in COVID-19 through their effects on the immune system. We identified bovine colostrum and hen egg white powders containing adequate quantities of these proteins. We investigated whether short-term daily consumption of a hen egg white and bovine colostrum mixture (reconstituted with glycerin and water) could reduce the risk of progression to severe disease and assist in the recovery of patients with mild or moderate COVID-19. Adults with mild or moderate COVID-19 who were within 5 days of symptom onset and had risk factors for severe disease were enrolled, and randomly assigned to take a hen egg white and bovine colostrum mixture or placebo mixture twice daily for 5 days, and then followed up telephonically for 6 weeks. The main findings were that consumption of the hen egg white and bovine colostrum mixture was associated with fewer protocol-defined severe-type symptoms overall, and in particular lower frequencies of joint pain/malaise, chest pain, fever/chills, and sore throat. Only one individual developed severe COVID-19 and therefore the effect of the intervention on reducing the risk of progression to severe disease could not be assessed. The results of this study suggest that consumption of the hen egg white bovine colostrum mixture within a few days of symptom onset lessens symptoms in people with mild or moderate COVID-19.
Ethical conduct of research The protocol was approved by the Biomedical Research Ethics Committee of the University of KwaZulu-Natal (BREC 00002220/2020). In addition, for investigations involving human subjects, informed consent has been obtained from the participants involved.

Summary points • Ovotransferrin and lysozyme in hen egg white and lactoferrin in bovine colostrum have immunomodulatory and antiviral properties. • It was hypothesized that consumption of a hen egg white bovine colostrum mixture in early infection would reduce the risk of progression to severe disease and assist in the recovery of individuals with mild/moderate COVID-19. • In this double-blind randomized control study, COVID-19-positive individuals at increased risk of severe disease and within 5 days of symptom onset were randomly assigned to consume a hen egg white bovine colostrum mixture (n = 77) or placebo (n = 79) twice daily for 5 days. • Only 1 participant (active arm) progressed to severe..
