Promilin®

A proprietary Fenugreek extract from TSI Health Sciences, that’s standardized to provide 20% 4-hydroxyisoleucine.  TSI claims its in-house, pilot studies show Promilin can help reduce glucose concentrations in “healthy, non-diabetic individuals” without affecting insulin levels – but their data is not available on their web site; nor has it been published in any peer-reviewed journal.
