All this about biofilms is expeculation but possible. We don’t have any proof that candida albicans is forming biofilms in the gut but very possible as I said.
We also don’t know if bacterial biofilm protocols are effective against candida biofilms since the matrix composition vary.
As an experiment, you can add some plant enzymes, lactoferrin, EDTA or follow any actual microbial biofilm protocol. EDTA is a chelator, and you need to consult if it is safe for you to take it.
