Garcinia Cambogia is a supplement to support weight management. The active ingredient is called hydroxycitrate (HCA) & 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 & reduce food intake. Unlike many over-the-counter diet aids, Citrin Plus is not a stimulant, & 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 & promote lean body mass.
