Insulin Sensitivity

Berberine

A plant alkaloid studied for its relationship to insulin sensitivity and how the body metabolizes glucose.

What Is Berberine?

Berberine is a naturally occurring plant alkaloid found in barberry, goldenseal, Oregon grape and several related plants.

Its Role In The GL-Defend Formula

It's a central ingredient in GL-Defend's insulin-response layer, working alongside Chromium.

What The Research Says

Berberine is among the more clinically studied natural compounds for glucose metabolism, with research examining its relationship to insulin sensitivity and healthy A1c levels.

Worth knowing: It's frequently discussed alongside more conventional glucose-support approaches, part of why it anchors many blood sugar formulas.

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.
