In a randomized, placebo-controlled study, scientists at the University of Mexico found that (–)hydroxycitric acid (HCA) as CitriMax® resulted in significant weight loss in obese subjects compared to those taking a placebo. Subjects took either a placebo or 500 mg of HCA before each meal for 8 weeks. No significant weight loss was seen in subjects receiving the placebo. Blood cholesterol and triglyceride levels were also significantly reduced in subjects taking HCA compared to those taking the placebo.
