A Randomized, Double-Blind, Placebo-Controlled Trial on the Effects of Dihydroberberine (DHB) on Glucagon-Like Peptide-1 (GLP-1), Glycemic Control, and Subjective Rating of Appetite and Mood/Energy in Adults With Pre-Diabetes

Summary

The goal of this clinical trial is to learn if Dihydroberberine (DHB) supplementation affects adults with pre-diabetes. The main questions it aims to answer are: Does DHB supplementation increase the concentration of GLP-1 in the blood? Does DHB supplementation affect appetite, mood, and energy levels? Does DHB supplementation affect body weight, blood sugar control and insulin? Researchers will compare DHB supplementation to a placebo (a look-alike substance that contains no drug) to see if DHB has any effect. Participants will: Take DHB or a placebo every day for 6 weeks. Participate in tests to measure GLP-1 levels, blood glucose, insulin and other markers. Have their continuous blood sugar profiles (with CGMs) monitored to see how much time their blood sugar spends in a healthy range. Rate their appetite, mood, and energy levels using a visual analog scale.
