CLA (conjugated linoleic acid) is a type fatty acid found in small amounts in foods such as milk, cheese and red meat. Although CLA is structurally classified as an omega-6 fatty acid, it's not an essential omega-6 fatty acid. Some research has shown fat-loss and lean-body mass enhancement effects from CLA and this has formed the basis for CLA's use as a dietary supplement.1
CLA is used primarily by those who want to decrease bodyfat and increase or preserve lean-bodymass. CLA's mechanism of action is incompletely understood. One possibility is that increases sensitivity to insulin, making the metabolism much more efficient. Another is that CLA may affect the liver enzymes that regulate fat-storage and fat-burning in a way that promotes the reduction of body fat. As a very safe supplement, CLA is particularly useful for those trying to shed body fat but without resorting to stimulant-based fat burners.
To get the best results from CLA, take it on a consistent daily basis for 8-12 weeks or longer. Best dose for fat loss is at least 3.4 grams per day, which is equivalent to 5 typical CLA softgels, which can be taken all at once or in divided doses.
