Breath Lab exists because the standard advice on bad breath is wrong.It isn't a hygiene problem. Around 90% of chronic bad breath comes from bacteria living on the tongue and throat, not the teeth — which is why brushing harder and rinsing more often never fixes it. Those bacteria break down proteins and release volatile sulfur compounds, and that's what people smell. Mouthwash removes the odour for twenty minutes and leaves the bacteria producing it untouched.Breath Lab Oral Probiotic is a nightly dissolving lozenge delivering 10 billion CFU across three strains chosen for their ability to colonise oral tissue rather than the gut. The lead strain, Lactobacillus plantarum LPc-G110, has been evaluated in a randomised controlled trial at ACTA, the Academic Centre for Dentistry Amsterdam, with results published in peer-reviewed journals. It's joined by Lactobacillus salivarius LS-G60 and Lactobacillus paracasei Lp-G18. The lozenge uses BioBubble delivery to hold the strains in contact with oral tissue instead of passing them to the stomach, and it's flavoured vanilla peach, sweetened with stevia and monk fruit, with no added sugar. In independent laboratory testing the blend inhibited up to 98% of volatile sulfur compounds, sustained through 24 hours. The Advanced Tongue Cleaning System handles the step before that. A dense biofilm on the back of the tongue shelters odour-producing bacteria and leaves nowhere for new strains to establish. The five-step kit includes a pineapple-derived bromelain enzyme serum that breaks down the protein structure of the coating, a bamboo tongue brush, both a flat and a U-shaped scraper, bamboo charcoal floss, and disinfection tablets for the tools.Used together, the system clears the surface and the probiotic repopulates it. Results build over weeks as the bacterial balance shifts.Worldwide shipping and a 30-day guarantee.

I am impressed by the simplicity in administering the Oral Probiotics. It is a very easy exercise which does not demand a lot. The company shares a tracking app by default, which gives comfort that the package is in transit. However, I got worried when the shipment took more than a month to arrive, but when it arrived, the service from the Postman was impeccable. I would definitely recommend the product to potential customers.

Got my order in the mail. Arrived really fast. I started the recomended plan. The company was helpful in showing me how to take. Results came quick. Ive tried Blis K12, oracare.. they're ok, but I found Breath Labratory to function the best. Seems to have a long lasting effect. There product is science backed

My honest experience has been great. The company is most helpful, answering all my questions, which gave me a lot of confidence to order. My package arrived in 8 days which was great. As for my bad breath, I only noticed a real change after 2 weeks. This is something that has bothered me for years. I've tried many "solutions" but none have worked like Breath Labs oral probiotic..

Took me a week to notice anything. Not sure if that is quick or not. But I keep them on hand now always.
