I cant say I have noticed a difference yet with the suppplements though I do feel the lactoferrin is doing me good.
I kind of came off the wagon this last week started by a family celebration where someone actually baked me some cake that I could eat that is until I stopped eating eggs. So I was so touched I ate some and then more plus the leftovers she left with me
They were also covered in whippped (sweetened) cream. So after depriving myself trying to go AIP it all went to pot. I had felt I wasnt improving but since this week I realise I was its back to easily pulled muscles all down my back again. Funny how you forget so easily what you had and dont notice the small improvements!
I have wondered about the sibo link. I dont have any symptoms of sibo but like you wonder if they are masked because we are already on a relevant eating plan. I am also now wondering if I am low histamine but cant face further limiting food. I would think the rice would be the culprit for you I have read conflicting advice on resistant starch with relation to klebsiella at least.
An interesting thing I came across today was that someone had been diagnosed with an overgrowth of klebsiella (non AS as far as I know) Their practitioner has told them to go no starch but also cut out fruit and go on an anti candida diet too I wonder what the relation with candida is. They have also thus far been prescribed nystatin (medication) and berberine. Berberine was one I was thinking of adding but hadnt found anything in relation to its effectiveness against klebsiella yet.
