A17 & K37
Immune Function

Lactococcus lactis A17
Lactiplantibacillus (Lactobacillus) plantarum K37

  • Isolated from fermented vegetables

  • 2 patents granted for each

  • Safe and clinically proven

  • Both A17 and K37 regulate mechanisms that cause allergies, asthma, and other immune system disorders

Clinical findings

We are committed to proving the benefits of probiotics through scientific research. Preclinical studies have demonstrated the following results:


  • Reduced immune response by reducing serum level of IgE and modulating expression of both B- and T-cells, NOD-1, NOD-2, and TLR-4

  • Both live and heat-killed forms shown to be effective


  • Prevented or benefitted asthma symptoms by alleviating airway hyper-responsiveness

  • Ameliorated allergic responses by regulating T-helper cell immune reactions, strengthening type 1 and attenuating type 2 responses

How they work

Our immune system protects us from potentially harmful foreign microbes and substances that enter our body. Much of it is controlled by the enteric nervous system within our gut and thus is directly affected by our microbiota. In some cases, such as allergies and asthma, immune reaction is excessive and ends up doing more harm than good. Probiotics such as A17 and K37 can work from within our gut to alleviate immune response.
