Main constituents

Mixture of active molecules sharing the same chemical composition, with slightly different structures; mostly cis-9, trans-11 and trans-10, cis-12 isomers of linoleic acid  

Main dietary sources of CLA: 

  • Meat from ruminants (lamb, beef, mutton, goat), milk, and other dairy products.

Sources for the production of CLA supplements:

  • Vegetable oils transformed by chemical reactions. 

Important Notice

  • *Findings from studies on humans do not support this use; rather they are contrary to these claims;
  • *It is impossible to evaluate the health effects of long-term use of CLA as a supplement since the development of insulin resistance has been observed in humans. Close medical supervision is therefore necessary for diabetics.
