I have no idea, but if I was going to wager a guess, it would be leaky gut. Until you get the leaky gut cured the candida can come back in the future. Also, you should get rid of any parasites you may have. Most people who have candida and/or LGS have parasites. They all seem to go hand in hand. I like Purify parasite cleanser. Of all the ones I've tried, I seem to get the most noticable die-off results from it. And while none of want die-off, at least you know it's working when you're taking it.
