Clinical study results of USANA Health Sciences products published in the Obesity and Weight Management journal

USANA Health Sciences, Inc. (NASDAQ: USNA) announced today that results of a large, third-party clinical study involving USANA products, conducted at the University of Colorado Denver (UCD), have been published in the August 2009 edition of the journal Obesity and Weight Management.

The recently completed study confirms that lifestyle change can significantly improve outcomes in subjects with metabolic syndrome. Metabolic syndrome is a pre-diabetic state that involves multiple symptoms including central obesity, insulin resistance, elevated blood lipids, elevated blood glucose, and high blood pressure. The 12-week-long study was conducted with 60 people diagnosed with metabolic syndrome. Subjects followed an Internet-based lifestyle modification program that included USANA's nutritional supplements, moderate exercise and a low-glycemic diet including USANA's nutritional shakes and bars.

Over the 12-week program, subjects in the study lost an average of 12 pounds and experienced significant improvements in measures of glycemic control, cardiovascular risk factors, inflammation and antioxidant status. Importantly, by the end of the trial, one-third of the subjects no longer met the criteria for metabolic syndrome.

Holly Wyatt, a physician and faculty member of the University of Colorado's Department of Medicine, Division of Endocrinology, Metabolism and Diabetes, oversaw the study. "This is a very promising program that produced some very positive changes in the cardiovascular risk factors associated with the metabolic syndrome," Dr. Wyatt said. "The shifts in dietary habits to calorically restricted low-glycemic meals and the modest increases in physical activity were not only effective but also are realistic behavioral changes many people can make."

“We are thrilled with the results of this clinical study and are excited to see it published in Obesity and Weight Management,” said Tim Wood, USANA’s Executive Vice President of Research and Development. “It is gratifying to have independent confirmation that our products and approaches to healthy lifestyle management work.”

    The results of the study are not surprising. I have been taking them for over 10 years with tremendous results. The products used in the sudy have been rated low glycemic (low GI) by the University of NSW and the Usana Vitamins Essentials have been rated No 1 in the US, Canada, Australia and New Zealand.

    Thats very nice Barbara, except that this website take no liability for anything, so even if the provided article was 100% incorrect and that the USANA product made some one grow an extra toe, the website wouldn't care and therefore and post anything on here. And the reason it is rated number 1 around the world could be of reasons influenced by its marketing scheme, the one that is taking advantage of others to make money for the person on top, the people would vote for it so that they can show off their products(not caring if it works or not) just to sell it and make greedy money. And is it rated No1 for what? magazine of the crappiest remedies? No 1 for the most dodgy marketing scheme? Where is it voted number 1 for?

      Dear James,

      USANA nutritionals are rated No. 1 by Lyle MacWilliam in his "Consumer's Guide to Nutritional Supplements". The author is not affiliated with USANA, and has worked on the government committee on nutritional supplements several years ago. It made him realize how terribly unregulated the supplements industry really is, so he decided to test various supplements in his laboratory (he is a biochemist with a PhD), and to write a guide to help consumers make educated choices.

      Hope, this helps. Laura

    Acually Lyle Macwilliam Worked for Usana as did the Doctors quoted in his book endorsing the book. The book is an Usana marketing tool.  He doesn't have his PHd. According to wikipedia, he isn't the only Dr associated with Usana that has "stretched the truth" about their professional involvement.
