Garcinia cambogia weight loss supplements are available for sale online at Amazon.com and Vita-Web.com, among other sites. However, insufficient evidence exists for the claim that garcinia cambogia can really help with weight loss, as WebMD points out.
Hydroxycitric acid, the active ingredient in garcinia cambogia, may help users feel less hungry and may block an enzyme the body uses to make fat. However, clinical trials show that people taking garcinia cambogia lose at best 2 pounds more than a control group. Garcinia cambogia may be beneficial to those trying to lower cholesterol or insulin levels, but should not be taken by anyone already taking medications for those conditions, according to WebMD.
