Why an oral probiotic is so important

Every day our mouths come into contact with billions of bacteria, and oral probiotics are essential to keeping your teeth, gums, and entire respiratory system healthy. Probiotics like BLIS K12 protect your body's "gateways" and support oral, nose, and throat health, freshen your breath, and support a healthy immune system.

How does BLIS K12 work?

BLIS K12 is a specific strain of Streptococcus salivarius, one of the dominant bacteria found in the oral cavity accounting for 15 to 40% of the total oral bacterial population, and the only probiotic developed to colonize in the oral cavity. Most probiotics work through competitive inhibition of undesirable bacteria, and S. salivarius does that as well. But BLIS K12 also produces two protective proteins—salivaricin A and salivaricin B, which help promote a healthy balance of bacteria, thus helping keep your mouth, sinuses, and throat healthy.

Impressive research results

The unique strain of healthy bacteria in Sinus Shield has been clinically studied with impressive results:

  • In one clinical study, BLIS K12 was shown to promote a healthy environment for the throat and pharynx in adults when taken on a daily basis.1
  • Additionally, in a study of subjects with bad breath, 85% of those taking BLIS K12 for two weeks had a significant reduction in the the foul smelling chemicals that cause bad breath, compared to 30% of those taking a placebo.2

I've always been a believer that the health of your mouth is a strong indicator of the health of your entire body, and that your mouth, nose, and throat are gateways to the rest of your body. That's why I feel Sinus Shield with clinically studied BLIS K12 is your best bet for sinus, nose, and oral health.

Science and Quality

Studies with S. salivarius K12 Show Increased Oral Health and Increased Immune Markers

In a study of 150 volunteers, those taking S. salivarius K12 (BLIS K12) showed improvements in dental health.1

Another small study revealed that within 24 hours of taking S. salivarius K12, markers of immune function increased.2 S. salivarius was found to increase salivary levels of interferon gamma, which suggests an enhanced immune response.
