You’ve got the cleanse down correctly. You don’t need to take probiotics on the cleanse…you’ll start taking them a few weeks after the cleanse (per the protocol). Same with antifungals.
I would do further research on whether you can obtain molybdenum in Poland. Google shopping and amazon.com are great resources. If there is another supplement that you are looking at instead, we can check it out for you if you share a link.
The cleanse is completely optional and only creates an environment that is beneficial to healing before starting the diet; it doesn’t even come close to completely killing off all of the candida, and for some the cleanse is too difficult/taxing.
Most people do the cleanse for about a week but you can stop at anytime.
