Does taking Yacon Syrup have any side effects?

No, unless you take more than the recommended dose. If you take too much at a time, you may experience a laxative effect, bloating, excessive gas production, digestive discomfort, as Yacon Syrup is an excellent colon cleanser! It is best to start out with just 1 teaspoon (a day) and then work your way up. People who frequently suffer from diarrhea or loose stools may want to avoid yacon.
