A one-year study found supplemental CLA reduced body fat mass in overweight but otherwise healthy adults by as much as 9 percent. Of the 157 participants who completed the initial study, 134 continued in an open study for another 12 months. They all took 3.4 grams a day of CLA (as Tonalin) or about 4-5 1,000 mg softgels. During the second year of taking CLA, the subjects did not regain body fat mass or body weight and achieved reductions in plasma levels of total cholesterol and low-density lipoprotein (LDL) cholesterol.
