I was taking 3 a day, but I think they may have been causing me too much gas, since they contain inulin. They were helping with the constipation, no doubt, but in turn they can cause severe gas for some people. That's why I stopped taking them and am now getting all my solubles from food. I am hoping this will stop the gas and tummy pain I get from trapped gas.... It's such a trial and error thing for most of us. What works for one could be totally wrong for someone else, even though they suffer the c type of IBS.
