Extract

Conjugated linoleic acid (CLA) is a collective term used to represent positional and geometric isomers of linoleic acid with conjugated double bonds. CLAs have been reported to have a wide range of beneficial effects, including: anticarcinogenic, antiatherogenic, antidiabetic and immune stimulatory. They have been shown to alter nutrient partitioning and lipid metabolism, and reduce body fat in a number of different animal species.
