How it Works

Dr. Francine Kaufman, M.D., a world-renowned endocrinologist and former President of the American Diabetes Association, developed a unique formula using a combination of proteins, fats and complex carbohydrates to help control blood sugar for up to 9 hours. The key ingredient is uncooked corn starch, a low-glycemic carbohydrate that metabolizes slowly.

Bood Sugar Chart

The low-glycemic carbs in Extend Nutrition products metabolize gradually. The result is stable energy for 6 hours during the day and 9 hours at night, as your body metabolizes faster during periods of normal activity versus periods of rest. Our products don't spike your blood sugar and therefore don't cause an insulin response; you will forget the 'spike-crash-crave' cycle and never look back.

Supported by peer-reviewed clinical studies and protected by 17 international patents, the Extend Nutrition formula is suggested to be effective in helping to control blood sugar for up to 9 hours and provide long-lasting energy.

  • World-Renowned Endocrinologist

Dr. Kaufman is strongly passionate about diabetes research and advocacy and is one of the world's leading authorities on the disease. Despite Dr. Kaufman's imminence in the diabetes and endocrinology communities, the story of her invention of the Extend Nutrition formula is a humble one. Dr. Kaufman developed a complex carbohydrate formula in her own kitchen which was later clinically tested and suggested to help control blood sugar. Effective for weight management, the Extend Nutrition product line is a direct extension of Dr. Kaufman's passion and brilliance in research.

Designed With A Purpose In Mind

Extend Nutrition products are designed to improve the lives of the people who enjoy them. We stand confidently behind our products because they are science-backed. As verified by the results of 6 clinical studies and by 17 international patents, our products are effective in helping to control blood sugar and limit hunger.

Supported by Science

A study to assess the efficacy of Extend Bar® as an appetite suppressant in males and females. A crossover study in moderately overweight subjects with BMI 27-31

Performed By: Glen Sussman, Ph.D. and Arush Anigrass, B.S.; Illinois Center for Clinical Trials, Chicago, IL, USA.

RESULTS: With p <0.005, the study showed a 21% reduction in calories consumed at meal time when ExtendBar was consumed as a between meal snack compared to a placebo snack.


The goal of this study was to obtain qualitative data regarding not only the effectiveness of Extend Bar as an appetite suppressant, but also to evaluate the taste of the active bar versus the placebo. As the data clearly shows, the bar is effective in reducing calorie intake, both by raw percentages and by statistical significance. This finding would be of immense benefit to a multitude of custromers, many of whom are attempting to lose weight by unsafe methods or means that risk complications. Extend Bar, by providing consumers with a product that is completely natural and devoid of known side-effects, fills a large need in the weight-control market. Consumers will appreciate and acknowledge this due to the effectiveness and safety of the product. The only negative aspect that may be considered is the taste. Although the taste of the active bar was not rated unappealing by any means, it was still statistically less appealing than the placebo bar. There may still be room for improvement in this area. Otherwise, this appears to be a viable market in the attempt to aid in the weight loss of tile general public.
