Reuteri+Salivarius starter pack

What motivated the creation of the Reuteri and Salivarius starter pack, as far the selection of this specific combination?

FYI: I made it once already and enjoyed it.

Many believe that those species help maintain dental and throat health.
However, those species also help maintain glycemic levels and, consequently, help the liver and kidneys, and although we used to have a lot of those back in the day, many people nowadays do not have this species in their microbiome.
Once we realised that, we introduced it first for a limited time, and now continuously, L.reuteri and Salivaroius blend to enjoy not only the unique taste but also hope that it will help maintain a healthy microbiome.
