How much mangosteen juice should I be taking?
For prevention, a minimal dose of 1 oz daily is suggested. Because certain xanthones can only be absorbed with some fat present in the digestive tract, mangosteen should be taken with food. In disease, when multiple mangosteen servings would be desirable these should be taken at intervals of four to six hours (the estimated half life of the xanthones). Therefore, taking the mangosteen juice at every meal would be ideal.
