3 Clinically Proven Ingredients. Supports Healthy Digestion, Suppresses Cravings, Helps Maintain Healthy Cholesterol Levels. Wilth Glucomannan Root Extract and Slimaluma. Top Secret Appetite Suppressant contains Slimaluma, an ingredient which has been clinically proven to reduce hunger levels, promote fat loss and manage body weight. Top Secret Appetite Suppressant also contains extracts of Glucomanna root and Green Tea Leaf. Glucomanna is soluble dietary fiber, which absorbs as much as 200 times its weight in water. The bulk-forming property of Glucomanna helps fill the stomach and reduce appetite. Additionally, Glucomannan forms a non-digestible coating around food particles, causing food to be digested more slowly. Because digestion is slowed, normal body blood sugar levels are maintained, which aids in controlling overeating, and helps fight the 'snack attacks' which often occur when blood glucose drops within hours after a meal.
