Mannatech, Incorporated (NASDAQ: MTEX), the leading innovator and provider of naturally sourced supplements based on Real Food Technology® solutions, announced today the publication of a study on The Effect of Dietary Supplements on the Quality of Life of Retired Professional Football Players. The study was published in the Global Journal of Health Science, Vol. 5, No. 2, 2013¹, e-Version First TM. http://www.ccsenet.org/journal/index.php/gjhs/article/view/21748 The open-label human clinical study showed that intake of Mannatech products resulted in statistically significant positive findings of general improvements in quality of life, satisfaction with health and physical and mental health of retired professional football players who used dietary supplements* †. The 15 retired football players who participated in the study took Mannatech’s Ambrotose® Complex powder, Omega-3 with Vitamin D3, Ambrotose AO® capsules, PhytoMatrix® caplets and PLUS™ caplets. Review of current scientific literature reveals that this is one of the few studies conducted on dietary supplementation and quality of life in retired football players using well-validated outcome measures. “We’re excited and encouraged by the results of this study,” explained Dr. Robert A. Sinnott, CEO and Chief Science Officer for Mannatech, Inc. “There have been various studies on dietary supplements released over the past couple years that have seemed, at times, confusing and even contradictory. The findings among this group of retired professional football players is significant in that it measures what most people are looking for in dietary supplements in the first place: an improved quality of life. Our company is founded on providing advanced nutritional technologies based on real-food sources that lead to definitive improvements in well-being. This study clearly supports our approach.” The study was authored by Dr. Robert A. Sinnott, Dr. Rolando L. Maddela, Dr. Sejong Bae and Dr. Talitha Best.
