Garcinia Cambogia is a supplement to support weight management. The active ingredient is called hydroxycitrate (HCA) and studies have shown that it is very safe. HCA helps inhibit fat production by temporarily inhibiting the enzyme ATP-citrate lyase that converts carbohydrates to fats in the liver. It also helps to curb your appetite and reduce food intake. Unlike many over-the-counter diet aids, Citrin Plus is not a stimulant, and wont cause side effects or lead to tolerance. Citrin Plus is 500 mg of Garcinia cambogia Extract plus 100 mcg of Chromemate brand Chromium Polynicotinate to regulate blood glucose levels and promote lean body mass.
