Toothpaste is super! Have used both C and F versions since our water is fluoridated by default. Both C and F work wonders; even my dentist asked what I’ve been using.
Seller was very helpful and prompt to reply to any questions.
If you want your best, healthiest smile, go with BioMin. My Mum used to work for a dentist and even she switched to BioMin when I gave her a tube…! haha
