    Garcinia cambogia is a fruit that has historically been used as a food-flavoring agent and in traditional medicine in Southeast Asia. More recently, and despite the need for more evidence to support its effectiveness, it has gained popularity as a weight-loss supplement.

    Overview

    Dosage information

    Formulation:

    Garcinia cambogia supplements are usually taken as capsules and are also often part of combination weight-loss supplements.

    The usual dosage is 1,500 milligrams per day (mg/day) of the active ingredient hydroxycitric acid (HCA), but some toxicology studies suggest a no-observed-adverse-effect level of up to 2,800 mg/day.[1]

    Range of dosages studied:

    Studies have used dosages ranging from 300 milligrams to 4,667 milligrams of HCA per day.[2][3] It is worth noting that not all the studies looked at Garcinia cambogia or HCA in isolation, and some used combination supplements.

    Effective dosages:

    People trying to lose weight

    Adults: 500 mg of hydroxycitric acid (HCA) three times per day before meals.

    Special considerations: Garcinia cambogia may have a minimal effect on body weight, and, although this is the most commonly recommended dose for weight loss, it might not be effective.[4][5]

    Other considerations:

    There are no recommended doses as yet for the other potential uses of Garcinia cambogia. This is because there is no evidence to support its efficacy outside of its use as a weight-loss supplement.
