Probiotics for Rhinitis
Probiotics for Rhinitis

Nasal health depends on the bacterial ecosystem in our nasal cavity. For this reason, probiotics can support both pulmonary and nasal inflammatory conditions including rhinitis.


Similar to all orifices in your body, the nose hosts bacteria that ideally serve a symbiotic relationship with their host: YOU. Similar to your gut flora your nasal flora is unique to you and is affected as much by genetic and environmental factors. In contrast, however, with our gut flora, the ones in our nose (as well as those in the vagina and mouth) are not directly affected by nutrition. Consecutively in order to support we have 2 options:
1. Direct administration of probiotics [ref]

2. Oral consumption of lozenges that will affect the proximal nasal ecosystem.


As far as probiotics go, Lactococcus lactis [ref1, ref2], Lactobacillus sakei [ref] & staphylococcus epidermidis [ref]  have been tested with positive outcomes. Unfortunately at the moment not all of them are commercially available.


If you are dealing with chronic nasal or pulmonary inflammatory conditions and need help you can reach out to me via the contact page.
