Fair questions
Does gymnema work?+
For blood sugar, it is not settled. Results lean positive, but there is not much yet.
Is gymnema safe?+
No caution is recorded on this page. That is not a safety guarantee; the studies we read were not safety trials.
Why only 1 source, when PubMed lists 22?+
The 22 is every paper that mentions gymnema in any way: animal studies, blood measurements, papers where it is a side note. The strongest sources are combined reviews, and each one already gathers every trial its authors could find. Our 1 cover 1 trials between them, and every one is linked above. Both counts are measured, not estimated.
