Cognis, manufacturer of Tonalin® brand conjugated linoleic acid (CLA), has released results from the first long term CLA study. The study, conducted by Jean-Michel Guallier and titled, “Efficacy and Safety of One Year Supplementation with Conjugated Linoleic Acid in Moderate Overweight,” demonstrated that Tonalin CLA reduced body fat by 9% and increased lean muscle by 2%. Overweight subjects were randomized in three groups and supplemented for one year either with CLA given as free fatty acid or as triglycerides and compared with a placebo (olive oil).
