Helps to support immune function in the upper respiratory tract


Supports antibody production

Stimulates the immune system

Targets respiratory system pathogens

Provides Immunoglobulin G (IgG)

Promotes production of Immunoglobulin A (IgA)

60 vcaps | NPN: 80108446

Bacillus subtilis supplementation during the winter period is a safe and effective way to stimulate immune responses in elderly subjects by inducing a higher concentration of IgA antibodies (Lefevre et al. -2015).

IgA antibodies are very important for lung health and can neutralize viruses 2, 3(Thorax – 1986; Mazanec et al-1992).


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

  • With patented Bacillus subtilis DE111 strain, for stimulating the production of IgA (Immunoglobulin A). IgA antibodies are very important for lung health and can neutralize viruses 
  • With IgG rich Colostrum to help support immune function within the upper respiratory tract 
  • With Andrographis paniculata extract standardized to 30% Andrographolide, which 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
