One other thing to look into is MSM. Their are claim s that it helps heal leaky gut. It also kills off parasites and fungus. But it is also a very powerful detox.
I don't know why I have taken about 4 doses in the past but the last one on Saturday really made me detox. The others didn't they just helped with the joint pain.
Look into ozonated water and ozone iv treatment vitamin c IV would have to 50 grams 3 times a week at least to help heal leaky gut. And dmso iv and msm iv. Natural path doctors do them treatments.
