A clinically studied plant alkaloid known to enhance insulin sensitivity and support glucose metabolism.
Berberine is a bioactive plant alkaloid extracted from several plants, including barberry, goldenseal and Oregon grape.
It's considered the anchor ingredient in GL-Defend's insulin sensitivity layer, working alongside Chromium.
Berberine is one of the more clinically studied natural compounds for glucose metabolism, with research examining its relationship to insulin sensitivity and A1c levels.
This describes general research on Berberine itself, not the finished GL-Defend product, which hasn't been the subject of its own clinical trial. See the full ingredients list or the formula overview for more.
