Clinical Study Shows that Ester-C® Stays in the Body Longer than other Vitamin C – PR Newswire (press release)

In this double-blind, placebo-controlled, crossover trial, thirty healthy subjects aged 18–60 years were randomized to receive placebo (0 mg vitamin C), ascorbic acid (1000 mg vitamin C), and Ester-C® (1000 mg vitamin C), each preceded by a 7-day washout period. The Ester-C® group had a significantly higher mean concentration change in leukocyte vitamin C, while there was no change in the ascorbic acid or placebo groups. The Ester-C® group also had a significantly higher percent change in leukocyte vitamin C compared to ascorbic acid at 8- and 24-hrs after the oral consumption.

Dr. Susan Hazels Mitmesser, author of the study and Sr. Director of Nutrition & Scientific Affairs at NBTY, said, “This study is a great example of the commitment NBTY has to scientific diligence around our product innovations. As new ingredients and areas of research emerge, our scientific leadership will continue to be a priority and a differentiator in the scientific community and the supplement market with NBTY products leading the way.”

“Ester-C is the only product of its kind on the market, and customers can easily find it by the ’24-Hour Immune Support’ call out on the label,” added John Frame, Vice President of Marketing for Ester-C®. “This product has been clinically studied to stay in the white blood cells longer than regular Vitamin-C — a distinct advantage to anyone looking to nutritionally support their immune system all day long.”
