I previously gave Bactose a 4 star rating because my first couple of rounds did not last very long. However, I have now been using it for months and have been able to enjoy dairy products and have peace of mind when it comes to accidental dairy consumption. The only downside is when my next round gets delivered late because I have to watch out for dairy until I can take my next round. Overall, this really has improved my digestion and gut comfort, and I will continue taking it for the foreseeable future.
