A great product is Fungal Defense. It's made by Garden of Life. You can find it on the web at www.gardenoflifeusa.com
This product works great and every so often I go on a treatment course of it and my intestines and body over all gets better. I can really tell when I need it is when my dandruff flairs up and my stomach gives me problems. My wife had a toenail fungus infection and was told by a foot doctor about taking an antifungal prescription and she declined because of the side effects(liver failure ect.) and decided to go the way of our naturalpathic doctor and used fungal defense by their directions on bottle. Her infection went away completely within a short time. The prescrition medication would take many months and only had a 60% success rate.
