Probiotic Advantage Oral Sinus lozenges deliver year-round oral and sinus support right where you need it most

  • Promotes healthy bacterial balance in the oral and sinus regions
  • Keeps your immune system strong
  • Helps keep your teeth, gums, throat, ears, and sinuses healthy
  • Promotes fresh breath

Probiotic Advantage Oral Sinus contains 3 unique strains of healthy bacteria that help to keep your teeth, gums, and entire respiratory system healthy.

The studies on S. salivarius K12 are extremely impressive. In one clinical study, S. salivarius K12 was shown to help promote throat, pharynx, and ear health in children.1

In a separate clinical study, S. salivarius K12 promoted a healthy environment for the throat and pharynx in adults when taken on a daily basis.2

Additionally, in a trial of 23 subjects with bad breath, 85% of those taking S. salivarius K12 for 2 weeks, compared to 30% of those taking a placebo, had a significant reduction in the foul-smelling chemicals that cause bad breath.3

  1. Streptococcus salivarius K12 generates 2 protective proteins—Salivaricin A and Salivaricin B—which are a natural defense against other undesirable bacteria.
  2. Streptococcus salivarius M18 contains 2 enzymes that protect teeth and gums from unwanted bacteria. In a placebo-controlled clinical study, children taking S. salivarius M18 had 100% improvement in their plaque scores.
  3. L. reuteri has been shown to help control plaque and support healthy teeth, mouth, and gums.

Plus, you get vitamin D and zinc to help support your immune system.

I take Probiotic Advantage Oral Sinus every day and suggest you do so as well. It’s also great for your children.

Science and Quality

S. salivarius K12

In a study of 150 subjects, those taking S. salivarius K12 had significantly reduced dental plaque scores.

In a study of 9 children, those taking oral S. salivarius K12 for 6 months exhibited better ear health.

A small study of 5 subjects found that within 24 hours of taking S. salivarius K12, immune markers increased.  Ingestion of the strain has been found to increase levels of interferon gamma in saliva, which suggests an enhanced immune response.

 S. salivarius M18

In a placebo-controlled clinical study, 83 children between the ages of 5 and 10 took part in a 90-day treatment protocol analyzing the effects of M18 on plaque and S. mutans counts. Children in both the placebo and treatment group (2x/d lozenges with 3.5 billion CFU of M18) received cleaning procedures at the start of study, removing any plaque.

Note: the version of M18 used in this study was a very early commercial form with a 20% colonize rate. Current versions have been optimized to colonization rates to >90% at only 1 billion CFU/day. Even with this early version, beneficial effects were still seen. 

At 90 days, 44% of kids in the control group had a 3 point plaque score improvement, while the M18 treatment group had 88% of kids with improvement. The other 12% of the kids did not have successful colonization of M18. In the kids where M18 did colonize, there was a 100% improvement. 

This distinctive strain is shown to promote healthy teeth and gums and helps to control plaque.

L. reuteri

L. reuteri is thought to be capable of promoting dental health by reducing bacterium responsible for tooth decay.

A double-blind, placebo-controlled trial showed that consuming L. reuteri in yogurt compared with placebo yogurt and yogurt containing other lactobacilli strains helped maintain a normal level of healthy oral bacteria as well as helped prevent bad bacteria from occupying the oral cavity.
In a randomized, placebo-controlled, double-blind study, 59 subjects were given 200 Million CFU/day or placebo over 2 weeks. Results: 

  • Plaque index scores fell significantly for patients consuming L. reuteri while there was no significant change in the placebo group.
  • L. reuteri helped maintain a normal level of healthy oral bacteria, as well as helped prevent bad bacteria from occupying the oral cavity.
  • L. reuteri helped support a protective and clean oral environment.

Vitamin D

Vitamin D plays a role in blood cell formation and it increases the activity of natural killer cells and T cells, supporting the immune system. Research has shown that individuals with higher levels of vitamin D are less likely to have symptoms of poor immune health. 

Zinc

 Zinc is an essential mineral that plays a role in over 200 different enzymatic reactions, mostly involving the structure of the body.
