CLA (Conjugated Linoleic Acid) is a class of fatty acids produced by animals that is naturally found in beef and dairy products. Although CLA plays an important role in a number of cellular metabolic processes, humans are not able to produce CLA and therefore can only obtain it from the diet. Since CLA is generally more abundant in grazing animals, changes in agricultural practices have resulted in less CLA in our foods, decreasing its availability in modern diets. Therefore, using a CLA supplement is recommended to obtain desirable levels of CLA for its beneficial effects.
