CLA is essentially a group of chemicals that are found in foods that are high in polyunsaturated fat. Often compared to `omega` fatty acids (like omega-3 or omega-6), CLA is regarded as an essential fat as it cannot be produced or synthesized by the body and we can only get it from our diet. CLA is known for supporting a healthy body composition. As CLA can only be obtained through your diet, and since relatively few foods contain it, it can be difficult to obtain in a useful amount. CLA extract in a supplement form is one effective method of getting sufficient levels of CLA without having to eat excessive amounts of red meat or dairy products.
