Garcinia cambogia is a popular weight loss supplement.

It is derived from a fruit of the same name, also called Garcinia gummi-gutta or Malabar tamarind.

The peel of the fruit contains high amounts of hydroxycitric acid (HCA), which is the active ingredient believed to be responsible for most of its weight loss benefits.

Garcinia cambogia is a small, pumpkin-shaped, yellow or greenish fruit.

The fruit is so sour that it is generally not eaten fresh but rather used in cooking .

Garcinia cambogia supplements are made from extracts of the fruit’s peel.

The peel of the fruit contains high amounts of hydroxycitric acid (HCA), an active substance that has been shown to have some weight loss properties.

The supplements generally contain 20–60% HCA. Nevertheless, studies show that those with 50–60% HCA may provide the most benefit.
