RCT of a Polyherbal Dietary Supplement for Prediabetes

The primary purpose of this study is to evaluate the impact of a polyherbal dietary supplement (Designs for Health - GlucoSupreme™ Herbal) on markers of glycemic control and other structure/function outcomes among a sample of prediabetic adults. A 12-week randomized, double-blinded, placebo-controlled clinical trial will be conducted to achieve the purpose of this study. The research team hypothesizes that GlucoSupreme™ Herbal will improve a variety of validated markers of glycemic control that are commonly used in clinical practice more effectively than placebo.
