yeah I can't tolerate supplements either. Get horrible reactions ( have for years )It's best to try and find out the reason for the leaky gut and then work at trying to heal. There is a test ( gosh I forget the name now ) but you would need an experienced alternative doc and finding anyone is like a needle in a haystack In my area anyway ). Thank God for this forum and the wonderful people here. It has been a big help to me over the years :-).
