Garcinia cambogia is an evergreen tropical shrub of the Guttiferae family native to Southeast Asia and in particular South India. It typically grows wild but is also cultivated in some areas.Generally, it is recommended to take 500 mg, three times per day, 30???60 minutes before meals. It is always best to follow the dosage instructions on the label. Studies have only tested these supplements for up to 12 weeks at a time. Therefore, it may be a good idea to take a few weeks off every three months or so.
