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 guggelsterones to manufacture guggul supplements.
Best-known for benefitting cholesterol and thyroid function, guggelsterones appear to help maintain normal thyroid hormone production while using thermogenics or a low carb-diet. Guggelsterones also benefit the skin and appear to lower serum triglycerides and cholesterol as well.*
