USANA Releases New Research On Vitamin D

SALT LAKE CITY, Jan. 22, 2013 /PRNewswire/ -- A new study by USANA Health Sciences, Inc. (NYSE: USNA), in conjunction with The Orthopedic Specialty Hospital (TOSH), suggests that inflammation may cause a decrease in the body's vitamin D levels. The study examined levels of vitamin D in twelve adult males between the ages of 18 and 45 recovering from anterior cruciate ligament (ACL) surgery.

"This research brings an awareness to managing inflammation in patients in order to protect them against vitamin D decreases," says Dr. Tyler Barker, Clinical Researcher at TOSH. "Preserving or maintaining a healthy vitamin D level is essential to the function of a variety of physiological systems. We plan to further investigate the influence of vitamin D supplements on vitamin D levels during inflammation."

Research for this study, which was published in October 2012 in Cytokine, The Official Journal of the International Cytokine Society, was funded in part by USANA Health Sciences, Inc. in Salt Lake City, a leading international manufacturer of top-quality nutritional products.

"We have a close partnership with TOSH in the scientific studies we conduct on our products. It was a privilege to be part of this valuable research," says Dr. Brian Dixon, USANA's executive director of scientific and clinical affairs. "The results of this study are significant in determining optimum vitamin D levels during periods of inflammation."
