Garcinia Cambogia
A tropical fruit extract often used for weight management and appetite control.
Also known as: Malabar Tamarind • Hydroxycitric Acid • HCA
Overview
Garcinia cambogia is a small, pumpkin-shaped fruit native to Indonesia, but also grown in India, Southeast Asia, and West and Central Africa. The rind of the fruit is rich in a substance called hydroxycitric acid (HCA), which is believed to be the active ingredient responsible for its potential weight loss benefits. HCA is thought to work by inhibiting an enzyme called citrate lyase, which the body uses to make fat. By blocking this enzyme, garcinia cambogia may help to reduce the amount of fat stored in the body. Additionally, HCA may increase levels of the brain chemical serotonin, which could help to suppress appetite and reduce cravings. While some studies have shown that garcinia cambogia can lead to modest weight loss, other studies have found no significant effect. The results of research on garcinia cambogia have been mixed, and more studies are needed to confirm its effectiveness. It is important to note that garcinia cambogia is not a magic bullet for weight loss and should be used in conjunction with a healthy diet and exercise program.
