Three supplements shown to help weight loss are garcinia cambogia extract, green coffee bean extract and glucomannan.
Gardenia cambogia extract
Gardenia cambogia is a tropical green fruit, shaped like a pumpkin.
The skin of the fruit contains hydroxycitric acid, which is the active ingredient found in gardenia cambogia extract supplements.
A number of animal studies have shown it can inhibit a fat-producing enzyme in the body and increase levels of serotonin, which can potential help to reduce cravings.
A 2011 review looked at 12 studies on gardenia cambogia and found, on average, it caused weight loss of about two pounds over several weeks.
Green coffee bean extract
Green coffee beans are coffee beans that haven’t been roasted, and their caffeine and chlorogenic acid content are believed to help aid weight loss.
