University of Wisconsin Researcher Presents New Insights on How Tonalin® CLA Reduces Fat and Promotes Long-Term Health Benef

Las Vegas, Nov. 6, 2007 – Prominent CLA (conjugated linoleic acid) researcher at the University of Wisconsin, Leah Whigham, PhD, shared compelling evidence from a recent meta-analysis to further support the well-known, body-toning benefits of Tonalin® CLA. During her special seminar at SupplySide West, Dr. Whigham summarized 18 randomized, double-blind, placebo-controlled CLA trials of which 15 were conducted with Tonalin® CLA.

Tonalin CLA® – The Most Clinically Studied Brand of CLA
According to the paper published in the American Journal of Clinical Nutrition1, Tonalin® CLA could enhance overall health by effectively reducing body fat, and potentially preventing weight and fat regain commonly experienced by adults. With rising numbers of overweight and obese Americans, it is becoming more evident that dieting alone doesn’t seem to help keep off lost pounds, as reported by UCLA researchers in a study recently published in American Pyschologist2.
“This meta-analysis suggests that CLA may be effective in combating the small, gradual weight gains that build over time and contribute to health problems down the road,” Dr. Whigham explained. “When the body of evidence is considered as a whole, CLA does have a beneficial effect on human body composition.”

After analyzing 18 eligible CLA studies that met their strict criteria (longitudinal randomized, double-blind, placebo-controlled human clinical trials using validated body composition measurements), Dr. Whigham and her colleagues concluded that among participants given 3.2 g a day, CLA produces a modest but significant reduction of fat mass of 0.2 pounds a week or 0.8 pounds a month compared to participants in the placebo group.

The meta-analysis includes findings of a landmark study by Dr. Jean-Michael Gaullier3. His research revealed that Tonalin® CLA not only reduced body fat mass in overweight adults by as much as 9 percent in one year, but also helped participants keep off the lost fat for a subsequent year during the follow-up period.

The Market Strategy Behind the Science-Based Brand
Sharrann Simmons, Senior Marketing Manager, Cognis Nutrition & Health, explained how the totality of scientific evidence provides a solid foundation for the marketing strategy behind the Tonalin® brand.

“It’s fact that CLA products with the Tonalin® brand on the package sell better than those without the well-recognized logo. It’s also true that Cognis’ combination of investment and commitment to R&D with innovative advertising continues to grow the CLA market, giving our customers a healthy advantage in an increasingly competitive category.”
Ms. Simmons pointed out that Cognis’ multi-pronged marketing program offers customers promotional support to help reach consumers online, in print, and in stores nationwide. “Cognis knows what messages resonate with consumers and our integrated marketing program continues to drive sales through co-promotional efforts, in-store visibility, consumer media coverage and targeted advertising campaigns.”
Cognis’ Tonalin® CLA is derived from natural safflower oil, is stimulant-free, and is the highest quality and the most clinically tested CLA on the market. As the study authors pointed out, with regard to both safety and efficacy, CLA products like Tonalin® enriched in both c9, t11, and t10, c12 isomers are preferable to those containing 4 isomers or single isomers. Tonalin® CLA meets high purity specifications in a 50:50 ratio of the two bioactive CLA isomers.
