Evidence notes

Monk fruit is recognized as safe by regulatory agencies and has traditional use history. However, human clinical trials demonstrating specific health benefits are sparse. Most evidence is limited to in vitro studies or animal models; human efficacy data for metabolic claims is preliminary.

Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
