Garcinia cambogia is a yellow or green tropical fruit native to Indonesia, with purported weight loss effects.
Hydroxycitric acid (HCA), the principle constituent of the rind of Garcinia cambogia, makes up about 10% to 50%. A study in 1998 reported that “Although hydroxycitric acid appears to be a promising experimental weight control agent, studies in humans are limited and results have been contradictory.”
In late 2012, Dr. Oz promoted Garcinia Cambogia extract as “an exciting breakthrough in natural weight loss”.
Consumers of hydroxycitric acid should be aware of the side effects. If 500 mg of hydroxycitric acid is consumed four times a day, it can cause nausea, gastrointestinal discomfort, and headaches.
You may be looking to participate in a weight loss study. Many of these studies offer compensation, and it could be a study to test a new drug, a new diet, or a new lifestyle.
There are several websites that provide a list of weight loss and obesity studies and clinical trials all across the United States.
