BIFIVIR® is a potent probiotic product designed to deliver high-potency strains that support the immune system, counteract pathogens, and combat oxidative stress and inflammation [1-4]. The five strains in BIFIVIR® strengthen immune defenses and optimize their protective function due to their unique properties:
Immunomodulation, including the ability to stimulate dendritic cell differentiation, activate natural killer cells, and increase IFNα and IFNγ secretion while decreasing IL-6.
Anti-pathogenic activity, effective against respiratory infections like Klebsiella pneumoniae and Pseudomonas aeruginosa, and protection of gut membrane integrity against external pathogens.
BIFIVIR® has undergone clinical studies for preventing winter diseases. In the first clinical study [6], 90 days of BIFIVIR® administration significantly reduced the prevalence, severity, and duration of flu episodes, upper respiratory tract infections, and acute respiratory infections, often by half. In the second clinical study [7], BIFIVIR® was tested alongside colostrum [6] to assess its effectiveness in preventing flu episodes compared to vaccination. During 8 weeks of supplementation and a 9-week follow-up, the group receiving both immunomodulators (BIFIVIR®+colostrum) had fewer flu episodes with reduced severity and fewer sick days. This approach also cut treatment and lost workdays costs in half.
