Scientists have repeatedly demonstrated the effects of this essential supplement on muscle tone and body fat. Use of Conjugated Linoleic Acid as a dietary supplement is covered under many US patents and is brand protected under the name Tonalin. HDT uses only Tonalin brand (60% Linoleic Acid) CLA. Researchers at the University of Wisconsin have shown CLA to play a vital role in shuttling calories towards muscle and away from body fat. This process is known as repartioning. CLA has been shown to play a vital role in reducing body fat and increasing muscle retention in laboratory and animal testing. Such testing does not establish that humans will receive the same benefits.
