Guggulsterones are plant sterols from the Commiphora Mukul tree. Long a part of Indian Ayurvedic medicine, guggul is harvested as a tree resin, then standardized for E and Z guggulsterones to manufacture guggul supplements.

Guggulsterones may help maintain thyroid function while using thermogenics or when on a low carb-diet. Guggulsterones also benefit the skin and appear to support healthy levels of triglycerides and cholesterol already within the normal range.*
