Clinically Tested Ingredient CLA is a newly-recognized supplement derived from natural sunflower oil. Years of research at the University of Wisconsin indicate that CLA may help "partition" the way energy is stored and utilized by actually "switching" calories to healthy muscle tissue…resulting in a reduction of body fat and an increase in muscle tone. Natrol's Tonalin CLA is the only patented form of conjugated linoleic acid.

CLA has been shown to play a vital role in reducing body fat and increasing muscle retention according to preliminary human studies, laboratory and animal testing.

CLA or conjugated linoleic acid is found naturally in a variety of foods. Over the past decade, however, our changing dietary patterns have diminished those foods high in CLA content. Now Natrol's Tonalin CLA offers a rich source of conjugated linoleic acid from the oil of the sunflower to supplement the diet naturally.
