HighWhat the studies found
By outcome
Guggul has an evidence score of 7.5/10 — strong evidence based on 36 indexed studies, including 1 meta-analysis. Guggulsterone-containing resin studied for lipid metabolism, thyroid function, and inflammation — promising but with mixed trial results.
The commonly studied dose of Guggul is 500-1500mg extract daily (standardized to guggulsterones). Research points to an estimated optimal dose around 1500mg, with a minimum effective dose near 500mg. Individual response varies — start low and adjust.
The best time to take Guggul is with meals. Take it with food. Guggulsterones (Z and E isomers) are the primary bioactive compounds in guggul (Commiphora mukul) resin.

Guggul is a resin from the Commiphora mukul tree, used in Ayurvedic medicine for thousands of years. It contains guggulsterones that may affect lipid metabolism, thyroid function, and inflammation. While early studies showed promise for cholesterol reduction, larger controlled trials have produced mixed results. It may still have benefits for inflammation and is sometimes used for thyroid support, though evidence is limited.
