It is always good advice to consult with your doctor before adding or discontinuing medicine. However, doctors are *not* pharmacists, who are the real experts here, so it is best if you talk to them first.
And, if they are unfamiliar with Gymnema, or NA (Stabilized) R-ALA, try another pharmacist. It is really hard for even them to keep up to date, especially with drug interactions, which for some drugs and OTC stuff like grapefruit, can run to half a dozen pages in small print.
NIH information about Gymnema.
