This is the best thing to have around when people are getting sick or if antibiotics mess with your mouth Flora. I dissolve two of these in my mouth every night before bed and kind of disperse it over my teeth with my tongue as like a brush and the next morning my morning breath, teeth, and mouth are much much more agreeable. Eliminates any film on your teeth when you wake up. This brand seems more effective than most other brands I have tried and I have tried MANY.

I prefer Hyperbiotics which contains more strains of culture. Hyperbiotics contains L. Para casei which Dr Williams brand does not. So I won't purchase this next time.<br /><br />Other wise OK. Tastes OK.

I tried these bc they were more cost efficient than a different brand I had used before. They seem to work as well, but I do not care for the cinnamon flavor.

My wife and I swear by it, as do others in the family. Takes down the symptoms faster than coldeze and zincam in my opinion. Downside is that it's more expensive.

I've enjoyed Dr David Williams products and thorough descriptions for some time, and was so thrilled to find a probiotic specifically for the oral cavity and sinuses that I actually signed up for autoship, which I stopped in general a few years back after building a supply for after the zombie apocalypse before getting it to stop. Truthfully, the shipping is always great, the product is pleasantly palatable, but I still have tooth decay and allergies, so it's hard to manage expectations, I guess?

Odd to have to brush teeth first but flavor is good. Makes your teeth feel clean. Seems to have lightened the sinus headaches a little bit so far. I will have to readvise as I continue taking it since I just started. I paid a promotional price to give an honest interview.
