This is a difficult one, and I have struggled with this. I found that every time I detoxed mercury with chlorella and NDF, after about two weeks I would have a candida flare-up, and that was a sign to me that I had indeed removed some of the mercury from my gut. After the second attempt, the candida flare-up was so bad it made me very ill and weak - I had leaky gut and was totally debilitated with crippling fatigue, food intolerances, hot flushes etc. I found by following the candida diet very strictly - no complex carbs, sugar, yeast, no just about everything - and taking an SBO probiotic, I have regained some territory and some energy. In his book Andy Cutler says that fixing the gut is essential in order to be able to absorb the supplements, otherwise these just become expensive sewage. I have found that, for me, keeping the candida at bay with probiotics (not with FOS), while detoxing mercury enables me to deal with both problems at the same time, as I wait to have my amalgams removed. I feel I have improved absorption and gained a tiny amount of weight. I haven't noticed that using probiotics makes my mercury symptoms worse, but then I feel generally unwell most of the time. For me, letting the candida proliferate out of control was a big mistake. Everyone is different, and will respond differently, and it's only by trial and error that we will find out what works for us. Good luck everybody.
