Monk fruit extract is very similar to Stevia in terms of how sweet it is (monk fruit extract is 150-200 times sweeter than sugar and stevia is 200-300 times sweeter than sugar). The research indicates that both are safe, don’t cause insulin or blood sugar responses, and may provide us with other health benefits. Monk fruit extract does have a slightly odd aftertaste that can be offputting to some (and so does stevia).

Regarding side effects, it looks like monk fruit extract is as lenient as erythritol. It may even cause fewer side effects than erythritol (since you will be using it in much smaller doses than erythritol).

Erythritol is roughly 70% as sweet as sugar, and I find it to be much closer to sugar in terms of taste.

I’ve also found that mixing erythritol with stevia or monk fruit extract provides the best flavor. However, since taste is highly individual, you may find that monk fruit extract tastes fine on its own. I’d say go with what fits within your budget and tastes best to you.

Does all of this make sense? If you have any other questions, please let me know.
