Conjugated linoleic acid (cla) is marketed to athletes as a way to change body composition and improve performance: Isomer of linoleic acid: essential fatty acid found in, lamb, beef, dairy products, major naturally occurring isomer = cis-9, trans-11, but more supplements have a mixture of the natural isomer and a trans-10, cis-12 isomer.
