Dymatize conjugated linoleic acid (CLA) contains an amazing 1,000 mg of Tonalin® per capsule. CLA has been shown to play a vital role in reducing body fat and increasing muscle tone according to human clinical studies, and laboratory testing. CLA was discovered in 1978 by Michael W. Pariza at the University of Wisconsin while looking for mutagen formations in meat during cooking. CLA is research proven to build muscle, reduce body fat, and induce an optimum cellular environment for improved health! CLA occurs naturally in foods such as milk, cheese, beef, and lamb as well as many processed foods. However, getting enough CLA from your diet for the preferred benefit would require considerable intake of these types of foods. This is not only impractical, but would also have a seriously negative impact on your metabolism due to the high caloric penalty you would pay. CLA by Dymatize is a great buy.
