Works great

I was starting to get a cold, so I took these, and they helped my throat feel better. I think they taste really good, too.

Throat Guard Pro

I've used Bliss for years now. Recommend it to all. At the 1st hint of a sore throat I start these. Within 3 days,it's under control. Always keep it on hand so I'm prepared. BEST product ever.

Excellent product

Had issues with always having a horrible taste in my mouth that would return 20 minutes after brushing my teeth. Dentist said my teeth are fine and recommended a probiotic. Took about 3 months of consistent use and I no longer have the horrible taste in my mouth and breath is fresher. Highly recommend.

Love all the Blis products

Have tested my oral microbiome and it is doing really well. I’m 100% sure that’s down to Blis products. Thank you - have recommended to many people

I rarely get infections, have great teeth and mouth health feel great overall

No more stinky breath is all I'll say. Thanks.

Excellent

I have been using ThroatGuard Pro with Blis K12 / High Strength for many years and do not travel without them. Both my husband and I have managed to stay well after long flights and during cruising. Highly recommend.

What are Oral Probiotics?

Oral probiotic lozenges or powder are specifically designed with the mouth and throat in mind, meaning they provide targeted support for these areas. Incorporating a daily probiotic supplement into your routine opens up the potential for a range of benefits.

Strengthened Oral Health:

BLIS Probiotics® oral probiotics maintain a balanced oral microbiome, supporting dental issues and promoting fresh breath.

Enhanced Throat Health:

Our unique strains of throat probiotics help soothe the throat and support a healthy immune system.

Improved Overall Wellbeing:

A healthy mouth and throat contribute to your overall health and vitality, and our probiotic supplements play a crucial role in supporting optimal wellness.
