Mannatech, Incorporated(NASDAQ: MTEX), the leading innovator and provider of naturally sourced supplements based on Real Food Technology® solutions, is holding MannaQuest 2012, its annual training convention for its North American Associates, at the Walt Disney World Dolphin Hotel and Convention Center in Orlando, Florida, this weekend, August 31 – September 2. Touted as the “Ultimate Training Weekend,” independent sales Associates from all over the United States and Canada will attend the event. While many training topics will be covered over the three-day convention, the event’s primary focus will be on launching Mannatech’s Xtreme Food Makeover campaign. With the launch of NutriVerus™ powder in May of this year, Mannatech created a way to boost the nutrition of anything you eat or drink. The supplement is a plant- and food-sourced powder that represents the best of Mannatech’s technologies in a single product, and can easily be mixed with any food or drink without altering the taste. The Xtreme Food Makeover campaign provides a simple, compelling way for Associates to share this message. “2012 has already proven to be a milestone year for Mannatech,” explains Al Bala, Mannatech Executive Vice President of Sales and Marketing. “With the launch of many new core initiatives earlier in the year that are having a great impact on our business, MannaQuest 2012 is our opportunity to bring it all together for our sales leaders and equip them with the tools and training they need to succeed, both right now and far into the future. We have a powerful message to share that the world is yearning to hear, and a simple system with which to share it. That’s what this weekend is all about.” Individuals interested in Mannatech’s products or in exploring its business opportunity can learn more at Mannatech.com.
