Does anyone have any more information on digestive enzyme supplements - specifically what they are, and what they do? I've tried researching it online, but all I find are websites trying to sell the stuff - nothing explaining how they actually work.I read a post here from someone who said it has helped them. So I went to GNC and bought their product called Enzyme Digestant. I've taken one pill a day for the past few days. I'm a type D exclusively, and so far I would say it definitely hasn't made things any worse. In fact, the only side effect I've noticed is incredible hunger pangs. I get so hungry in between meals I feel like my stomach is going to literally implode. Granted, I would take that any day over the queasiness I usually feel.Is D sometimes caused by food not being digestable? When I eat lettuce, for instance, it seems to go right through me without even being digested. Is my body trying to flush it out of my system by dumping water into my intestines? If this is the case, then could taking a supplement such as this help my body to digest things better and decrease D?
