If I can just jump on on this thread. I took Algin after my last amalgam removal - started at 1 three times a day rising to 2 three times a day the next day, and developed the most awful stomach ache. Why would this be? I stopped taking it and the stomach ache subsided over 2 days, and I have no doubt it was the Algin. I know its indigestable fibre - is that why it could have given me stomach ache? I always drink lots of water.
