As I recall Miswak tasted weird but I got used to it. I think I just decided that it 'probably' wasn't doing as good a job of cleaning things as I would like. I would be interested to read a scientific study of it though.

The toothpaste I am using is made by 'Green People' and is the only organic one I have found. I did try making my own a couple of times but despite buying the right ingredients, I never quite got the mixture right to produce the consistency I like. In the end I gave up and went back to a manufactured one.

To learn more about K2 you can look into the work of Weston Price, but he and his followers are typically anti vegan and pro carnist, claiming that K2 can only be found in sufficient amounts in bone broth and things of that nature. They do provide an approach for vegans but don't recommend it. I do have K2 supplements because I don't really like much fermented foods but they are so good for gut health too that I am more motivated to learn to like them than I am to keep taking supplements!
