Conjugated Linoleic Acid (CLA) is an essential Fatty Acid with a number of fat-burning effects. Research has shown CLA to enhance fat loss whilst preserving lean muscle. The potential beneficial effects of CLA on human health have been widely investigated and proven effective in weight management. Several studies have demonstrated that CLA can positively affect body mass and has a beneficial effect on lean muscle mass. CLA also increases the activity of hormone sensitive lipases, which result in the breakdown of stored fat. As CLA makes more fat available for energy the body is able to spare glycogen and therefore enhance endurance performance.
