What is CLA (Conjugated Linoleic Acid)?

CLA (Conjugated Linoleic Acid) is a naturally occurring fatty acid found in cow’s milk and is made up of a group of isomers of linoleic acid (omega-6). The cis-9, trans-11 isomer (rumenic acid) is the predominant isomer in foods and accounts for up to 90 % of total CLA found in dairy products. Dairy products are the richest dietary source of CLA, providing 70 % of intakes, compared to 25 % from beef and smaller amounts from other ruminant sources. The amount of CLA in milk and dairy foods can be influenced by feeding practices, with cows that are grass-fed producing 300-500 % more CLA than those grain-fed. This is of particular relevance to Irish dairy, where cattle graze on grass for up to 300 days each year.

Extra Information:

While some research has indicated a number of potential health benefits of CLA and while it has been marketed as a nutritional supplement, the existing evidence is inconclusive and currently no authorised health claims exist for CLA.
