Supplements can be a lifesaver when you’re low on nutrients, but let’s be real—sometimes they do more harm than good.

Take the wrong dose, or the wrong kind, and suddenly you’re dealing with bloating, cramps, or worse.

Here are 10 common supplements that could wreak havoc on your digestive system—and how to take them smartly.
