I tried it, it worked for a day or two, but I was careless with it and ate a bunch of junk while using it, so the candida adapted to the graviola and now it does nothing against it. This will happen with every supplement. Diet is key, supplements are just added bonuses.
But yes, I tried graviola, it did not completely kill candida like I thought it would, and I still had to adhere to an anti-candida diet in order to really kill it. I am cured now though, or symptom free rather, as there is no miracle cure for candida, just a lifestyle change that needs to be made. I stopped using graviola after I realized it wasn't a miracle pill and only used ACV while I did my anti-candida diet.
Sorry for rambling. I do think that graviola can work well in conjunction to an anti-candida diet, but it's not a miracle pill sadly.
