Tonalin CLA is a naturally based specialty ingredient which has been clinically proven to reduce body fat up to 10% while maintaining lean body mass, & preventing fat regain. When you consume fat that your body does not need to use for energy, it is absorbed by fat cells with the help of an enzyme called lipoprotein lipase.CLA blocks this enzyme & diverts unused fat to your muscle to burn this fat, especially during exercise. Because it is so effective, Tonalin CLA can also help eliminate the unhealthy "yo-yoing" pattern of losing & gaining weight. Clinical studies have proven that Tonalin can prevent fat regain. The USN CLA & Raspberry Ketone drink has been enhanced with raspberry ketone, which research suggests holds promise as an herbal since its biological activities alter the fat metabolism in fat cells.
