Hi @recoverymom 🙂 Sorry you are in the club, but here we are, and grateful to have this group.
I have trialed all sorts of probiotics, but the ones I feel have helped the most are Metagenics Ultra Flora Intensive Care and Clinicians Flora Restore. When I have an infection, I use them together and continue to use them together after I stop the ABs. When I am on rotational ABs for longer lengths of time I just continue to use both of them. When I have a reprieve from the infections, I use the Flora Restore on and off. My prebiotics are in non-fermented foods.
From time to time, I would use Mega Sporebiotics (with bacillus species).
If you google these products you will get the names of the specific species and strain, plus dose per capsule. Hope that is helpful.
I personally found the fermented foods did not agree with me, too acidic. I felt that they could potentially add to my risk of candida, thrush etc. being I was on so many ABs so much of the time and adding to yeast pathogenesis. I am pleased to say I have never had thrush, candida or gut issues. The vaginal probiotic seeding is valuable.
I am currently working on trying to down regulate quorum sensing and increase biofilm disruption, targeting the embedded bacteria. I have done this in the past with some limited success.
Take care, its a hard road we travel.
