  • Mannatech’s Continuing Professional Leadership in Quality and Compliance

    Mannatech’s team of QA, Research and Development and Regulatory Affairs professionals work hard to ensure that our products are of the highest quality and meet country-specific regulatory standards. Because regulatory quality standards are complex and subject to change, it’s essential to have an expert in charge. Long-term Mannatech employee Ms. Sharon McNair, a Certified Quality Auditor (CQA) by the American Society for Quality (ASQ), is up to that responsibility.

    Devoted to keeping abreast of quality regulations and fostering continuing education in the wider quality community, Ms. McNair was elected Secretary of the Dallas ASQ section in December 2016.  As Secretary, she maintains minutes for monthly Dallas ASQ general and leadership meetings and serves as a voting representative for the Dallas section of the organization’s world quality group.  The 900+ members of the Dallas ASQ section represent a wide-range of industries, including hospital, dietary supplements, foods and drugs, medical devices and the aerospace industry.  The concerns of this group encompass quality systems for all areas of corporate functions, including human resources and business systems.  Given the diversity of this group, Sharon recently established and now chairs a Dallas ASQ Food, Drugs and Cosmetics Special Interest Group (SIG) so that the specific needs of quality professionals in these areas can more easily be met. Meetings will be held at Mannatech’s corporate headquarters.

    Mannatech Celebrates Publication Citation Milestone

    About six years ago Mannatecphoto of Jane and Erikah realized that, to facilitate scientific understanding of the effect of dietary polysaccharides on the immune system, there was a pressing need to consolidate and describe the existing immunologic oral polysaccharide literature. Always ready for a challenge, Mannatech scientists decided to take on the task, and their systematic literature review was published in Nutrition Journal in November of 2010.
    This review has indeed been of great interest to researchers around the globe who are striving to better understand these complex and often potent natural molecules derived from plants and fungi. In fact, Mannatech recently celebrated a significant milestone for this literature review: the article has been cited in over 100 research publications!
    “We’ve always recognized the need for strong product validation, as evidenced by pre-clinical research and human clinical studies that have documented the benefits of our core products for people,”* commented Tait Switzer, Vice President of Research and Development at Mannatech. “International recognition of the importance of this literature review and rapidly growing interest in oral polysaccharide research further demonstrates that we are truly advancing the scientific understanding of the benefits that can be derived from dietary polysaccharides.”

    Mannatech’s Leadership Role in Quality and Compliance

    SM-news2015Mannatech has been steadfast in its commitment to producing the highest quality scientifically validated products that meet country-specific regulatory standards. Working behind the scenes for over 12 years to help make this happen is Ms. Sharon McNair, Mannatech’s Quality Assurance Manager.

    An important component of Ms. McNair’s responsibilities is staying abreast of ever-changing Quality regulations. The American Society for Quality (ASQ) is an outstanding resource for Quality professionals serving diverse industries who seek continuing education and productive interactions with industry peers. At the ASQ World Conference on Quality and Improvement in early May 2015, Sharon asked that a Dallas-area regional special interest group (SIG) be formed so that Quality Food, Drug, Supplements and Cosmetics professionals could meet and discuss issues relevant to their industries. Approval was provided in June 2015 and Ms. McNair agreed to serve as the inaugural chair of the SIG. During SIG meetings, held monthly at Mannatech’s corporate headquarters in Coppell, industry members share their knowledge and experiences in implementing Quality procedures that enable them to comply with federal and state regulations. As a Dallas ASQ section team member, Sharon also proctors quality professional’s certification examinations.

    “I am an advocate for continuing education and learning new ways to improve my knowledge,” explains Ms. McNair. “I love Quality and I work daily to improve Mannatech’s processes to help ensure our products are of the highest quality, which includes identifying what is perceived as a quality measure for the countries we service. Recent recalls of other company’s products do harm to the entire supplement industry. It is my hope that consumer trust will be bolstered by our SIG working together to implement and adhere to Quality standards.”

    Mannatech Presents Glyconutrient Science at the 10th Jenner Glycobiology and Medicine Symposium. Mechanisms That Might Contribute to the Cognitive Benefits of Mannatech’s Ambrotose® Polysaccharides Are Presented.

    apr-5-2012Mannatech recently presented product research at the prestigious 10th Jenner Glycobiology and Medicine Symposium, which was held in The Hague, the Netherlands, March 31-April 3, 2012. The pre-clinical study showed that intake of Advanced Ambrotose® powder had positive effects in the brain on the expression of genes associated with the regulation of learning, memory and mood (1)*. These preliminary findings are compatible with multiple controlled human clinical studies which indicate that intake of Ambrotose products provides significant cognitive benefits to healthy adults.*

    The study was authored by Dr. Erika N. Nelson, Jane Ramberg and Dr. Robert Sinnott. Dr. Nelson earned her BS in Genetics from the University of Kansas in Lawrence and went on to obtain her PhD in Neuroscience at the University of Texas Southwestern Medical Center in Dallas. She has published a number of papers on neurodevelopmental disorders and brain epigenetics. A candidate for a Masters of Business Administration at the University of Texas at Dallas, Dr. Nelson is also a consultant for Mannatech. Dr. Sinnott is CEO and CSO at Mannatech and Jane Ramberg is Director of Product Substantiation at Mannatech.

    The 10th Jenner Glycobiology and Medicine Symposium brings together scientists from around the world, including many thought leaders in the field of glycobiology. The United Kingdom’s Royal Society of Medicine has been hosting these meetings—devoted to providing a forum for scientists and clinicians to disseminate the findings of current leading edge research in both novel and classic fields of glycobiology—for over 20 years.

    Australian Scientist Wins Researchers in Business Project Funding

     Dr. Talitha Best
    Dr. Talitha Best

    The Australian government has granted Dr. Talitha Best a 12-month Researchers in Business (RiB) grant to help develop research on Mannatech’s glyconutritional products. The RiB program is part of Enterprise Connect, an initiative within the Australian government’s Department of Innovation, Industry, Science and Research. The program is designed to accelerate industry innovation and competitiveness by connecting university and public agency researchers with businesses that wish to develop new ideas with commercial potential. RiB initiatives are destined to play an important role in enhancing the transfer of university intellectual capital into practical business applications and to stimulate the dissemination of industry knowledge back into the research community. Exciting innovation is expected to flow from breaking down the cultural divide between academia and business.

    For more than six years, Dr. Best, a post-doctoral research fellow at the Nutritional Physiology Research Centre, the University of South Australia (UniSA), and the Brain Sciences Institute, Swinburne University of Technology, has been investigating the impact of dietary saccharides on human brain function. Based at UniSA, she has presented her findings at numerous scientific conferences and has shown, in two randomized, double-blind, placebo-controlled human clinical trials, that intake of Mannatech’s saccharide supplement, Ambrotose® complex, can provide both immediate and long-term improvements in memory, cognition and well-being (1),(2)*.
