I have taken olive leaf extract for 4 weeks ( 2 capsules daily).I'm sure it has reduced the quantity of microbes in my gut and body generally.And how did I find it? well that period and 1 month later my farts(sorry) were odorless. My semen also was odorless(still remains almost so). I have less bloating than before taking OLE.
When I took it, I initially had herx reaction that lasted for only 2 days though.Mainly headache(couldn't sleep the fist night.But I think it worthed taking it.

ps you surely know that leaky gut and microbes go hand by(?) hand
