Of the list of things in the supplement, glutamine is thought to help repair leaky gut. I take powdered gelatin instead - more cost effective and contains other beneficial amino acids for leaky gut

I also take berberine as an herbal antibiotic for a short stretch every few months, but in substantially larger amounts (i.e., 1000mg, not 3mg)

Note that a bunch of the ingredients are likely starchy: cinnamon, cloves, black pepper. Though the amounts are quite small.

I see you posted this awhile ago...would love to hear how it worked out
