Description CLA Burn contains high quality conjugated linoleic acid (CLA) derived from 100% pure safflower oil. Recent scientific studies have shown that CLA reduces body fat while maintaining lean body mass. CLA is a natural ingredient that works to block the enzyme called lipoprotein which helps to absorb fat into fat cells. CLA blocks this enzyme and diverts unused fat to muscle cells. CLA then activates enzymes which help your muscles to burn this fat. This increased breakdown of fat helps to prevent fat accumulation in fat cells and helps to fuel and preserve muscle mass.
