Support antibody production

Stimulate the immune system

Targets respiratory system pathogens

Provides Immunoglobulin G (IgG)

Promotes production of Immunoglobulin A (IgA)

Subtivir is an innovative combination of ingredients that support antibody production, stimulate the immune system, and attack pathogens with a focus on the respiratory system.

While standardized bovine colostrum provides Immunoglobulin G (IgG), Bacillus subtilis stimulates the production of Immunoglobulin A (IgA). Bacillus subtilis supplementation during the winter period is a safe effective way to stimulate immune responses in elderly subjects by inducing a higher concentration of IgA antibodies. IgA antibodies are very important for lung health and can neutralize viruses.

Immunoglobulin G (IgG) rich colostrum helps to support immune function within the upper respiratory tract.

Andrographis paniculata standardized to 30% Andrographolide was found superior to placebo for reducing symptom severity in upper respiratory tract infections. The dominant symptom relief is improvement in cough intensity and frequency as well as a reduction in severity of sore throat symptoms.
