The Claim

Steviol glycosides and mogrosides derived from natural sources such as stevia and monk fruit are not absorbed systemically in significant quantities, are metabolized by gut microbiota into steviol and mogrol, which undergo glucuronidation, and are subsequently excreted in urine, resulting in no caloric contribution.

What the research says

Roughly balanced

Support and challenge are close. The picture may shift as more studies come in.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

The sweet compounds from stevia and monk fruit don’t get absorbed into your bloodstream like sugar does. Instead, your gut bacteria break them down, and your body flushes out the leftovers—so they don’t give you any calories.
