This product is supported by clinical trials and is scientifically tested. The brand invented Blis K12 so no one has more experience in oral probiotics then these guys.<br />I suffered from sore throats for years until I found the Blis brand. There is nothing more effective out there to build immunity and its completely natural. I have not had a cold or flu since using this product and am so happy its now available in a small handy container I can take anywhere. This is now my go to product for staying well all year round and gives me the ultimate piece of mind.

I am genuinely lost for words! Being a big fan of Blis K12 for about a decade, I was excited to try the oral probiotic Blis K12 from its source, Blis Technologies. Working in the promotional field, with the public, and in retail, I would catch two to three colds a year. Since I discovered Blis K12, I have only been sick once, and that was when my retail sources stopped carrying the brand I initially used. I have been ordering it through the mail from various companies for the past few years. I received the UltraBlis with high expectations. It arrived with a beautiful, sturdy container with a defective safety seal. The product's rather flimsy and crushed box was not sealed either. I wonder if it had been returned and reshipped to me. How can I ever trust to order this product again or even ask for a replacement when the product's safety is in question? I can't. I have asked for a refund and am ordering one of my regular brands. Blis Technologies need to rethink the safety and way they secure their products. I am tremendously disappointed.

I’ve been using BLIS probiotics for about a year now and highly recommend them. For my entire life I’ve suffered from throat infections and BLIS probiotics have helped me stay healthy since I started taking them. I use them every night before bed and use the Honey BLIS lozenges during the day. Fantastic product!

This product is almost twice as strong as ProBiora Plus. It’s not as sweet, but it dissolves just as easily. I appreciate the fact that the strength is so much greater than that of the ProBiora. I will definitely buy this product again.

I've been using this twice a day every day and I don't feel like there's a noticable difference. I have lymphoma which causes a weak immune system. I also have a slight post nasal drip as well as asthma. I will continue to take them and hope for a significant change.

Bottle says flavor is peppermint but it tastes only like vanilla... not even close to peppermint. Also is a bit on the expensive side for a basic probiotic.
