The only thing that solved my bad breath issue….

Having been told by my wife that I had bad breath, I was mortified. I tried salt water mouth wash, tongue cleaning, kefir, yoghurt, flossing…. You name it I did it.

In the end, the blis products solved the issue. I floss, brush, use a tongue cleaner and then use one blis vanilla lozenge and it has helped immensely. I can’t thank the blis team enough. Thank you all so much!

Effective and taste great

I am convinced that these throat probiotics ward off colds etc. I woke up feeling like I was going to get a cold, took one of these twice that day and for a few days after and the cold never progressed

Since my family and I started using Ultra Blis we never get sick anymore. Occasionally one of us my get a few symptoms of a URTI but it doesn't develop into anything. Best product on the market for supporting your gut micro biome and immunity. Would definitely recommend 👍

They work

They actually work for sore throat’s and mouth ulcers - clear them up within 24 hours. Unfortunately they don’t work on my tonsillitis but everything else is great and they keep your teeth clear from bad breath.
