Your doctor may recommend a digestive enzyme if you're having trouble breaking down certain carbohydrates. However, currently, there is little evidence that combination digestive enzymes are not traditional digestive enzymes like Beano. For example, it is helpful for people with common gut problems like heartburn or IBS. There have been cases where digestive enzymes have been effective at reducing bloating. But for now, the research is ultimately conflicting at best. I also want to flag that many over-the-counter digestive enzymes have not been regulated or scientifically evaluated for effectiveness. So I would caution against their use and always speak to a doctor before shelling out the cash for these supplements.
