In an open-label human dosing study, Dr. Azita Alavi, a Research Fellow at the Sir Joseph Hotung Centre for Musculoskeletal Disorders, Division of Cellular and Molecular Medicine, St. George’s University of London, U.K. and colleagues showed that intake of Advanced Ambrotose® powder resulted in a significant shift towards increased sialylation in the N-glycosylation profile of the serum of healthy adults. To the authors’ knowledge, this is the first study which has shown that dietary changes can affect serum glycosylation profiles. Co–authors include St. George’s University researchers Professor John Axford, Dr. Edward Tarelli and Dr. Owen Fraser, and Professor Martin Bland, Department of Health Sciences, University of York, UK. Study was at least partially funded by Mannatech.
