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.

Thanks so much, Johanna! We’re really happy to hear you’re enjoying it and that it’s leaving your mouth feeling fresh and clean. We looked into your order and can see it was placed on September 13 and delivered on October 1, 18 days later. Our average delivery time to the UK is around a week, so this was definitely longer than usual, and we apologize for the delay. We really appreciate your patience and your review! 😊

Thank you very much for commenting. We appreciate the feedback
Tried everything for years! So glad I found an alternative to mouthwash which kills all your bacteria and often left me with digestive issues. Im no longer waking up with * death breath" and my girlfriend loves it. Noticed a huge difference within a week. Life saver can't reccomend enough!

Thank you so much, Kailey! You’re absolutely right that many conventional mouthwashes can be quite harsh and may disrupt the balance of the oral microbiome. Thank you for sharing your experience!

I have had a good experience with it, and after many years of suffering. I will keep using it. I can confidently recommend this to anyone who is suffering from bad breath.
