CLA

CLA (conjugated linoleic acid) is a polyunsaturated fatty acid found naturally in milk and meat and produced from safflower and sunflower oils. There are various forms or isomers of CLA that may perform different functions. The cis-9, trans-11 isomer (also written as c9, t11) is the predominant type found in milk and meats. Supplements are typically made from safflower or sunflower oil and have an equal mixture of cis-9, trans-11 isomer and the trans-10, cis-12 isomer (also known as t10, c12).

CLA has been shown to help with slimming by increasing the ratio of muscle to fat, that is increasing lean body mass. It has not been shown, however, to reduce overall weight. The trans-10, cis-12 form appears to be the form most associated with changes in body composition(safflower & sunflower oil).
