Stored fat belly burner is a truly unique weight management formula.* At the heart of this product is sinetrol, a powerful ingredient that has been researched for its ability to metabolize stored fat in the body, including stubborn areas, such as the belly, waist and hips.* It works by stimulating lipolysis, a catabolic process leading to the breakdown of triglycerides stored in the fat cells (adipocytes), releasing free fatty acids (FFA).* Sinetrol reduces body fat to help you reach and maintain a healthy body composition.* This product also includes other fruits such as grapefruit, sweet orange, blood orange, lemon peel and tangerine as well as our bioperine complex for enhanced absorption of key nutrients.*
