Magical lozenges

Been using the BLIS throat lozenges for over six months now and have had a tickle in the throat a couple of times during the winter months but both times after taking a lozenges within a few hours back to normal. I was going to cancel my subscription but for the little money I spend it’s a well worth the investment.

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
