If you know that your body odour problem is definitely caused by Leaky gut syndrome then something like Champex or Odour cleanse might help.
I think my odour problems might be caused by parasites but I am using champex at the moment as well as a parasite cleanse and the champex helps a little bit with the smell as because of all the toxins that are being releasd by dying parasites etc the smell has been worse recently. So look up the other threads on this forum about Champex. It helped some people but made the problem worse for other people so have a read and see what you think.
I do beleive in God as well and I pray for deliverance on a daily basis. I also ask that he keeps his hand on me in the midst of all this, that he helps me to thrive and choose blessings over bitterness inspite of what's going on around me.
