Does this also contain the blis m18? another identical amazon product by blis says it does. but it's $15 more.

UltraBlis contains the K12 strain and not the M18. It does have other targeted strains for the gut and upper respiratory tract. I take this daily and It has worked very well. I have not had a sore throat since I started. Also, no more mouth sores from irritations caused by retainers.

Does this contain stevia?

No, it does not contain Stevia. kind regards Team BLIS

How does it survive stomach acidity ?

The number of bacteria included in the formulation should bypass the stomach fine. We base this off the large number of studies using these gut strains (LA 14 and HN019) where they formulated these into food formats e.g. milk or water which would mean the strains are exposed to the stomach acid similarly to when formulated in a lozenge but still demonstrate safety or efficacy.

Does streptococcus salivarius (k12) help with nitrate production?

Hi, Thanks for getting in touch! There is currently limited evidence of the role K12 plays with nitrate production in the oral cavity. However, it is suspected that Streptococcus salivarius do play a role in oral nitrogen metabolism, but that role still requires further scientific investigation. Kind regards, Team BLIS Probiotics
