SALT LAKE CITY, Nov. 14, 2012 /PRNewswire/ -- USANA's vision of excellence is crystal clear. USANA Health Sciences, Inc. (NYSE: USNA), a global nutritional company, announced today that its advanced eye health supplement, Visionex®, has been evaluated and approved by ConsumerLab.com, LLC, a leading provider of independent product test results. (Logo: http://photos.prnewswire.com/prnh/20120807/LA53885LOGO) In a recent study on eye health supplements, ConsumerLab.com determined that USANA's Visionex® contains at least 100 percent of the claimed amounts of lutein and claimed amounts of zeaxanthin listed on the label; satisfies California's Proposition 65 levels for lead contamination; adheres to recommended United States Pharmacopeia (USP) disintegration parameters; and meets Food and Drug Administration (FDA) labeling requirements. "We know our products contain exactly what is listed on the label, but it's critical to have third-party confirmation and approval," says Dan Macuga, USANA chief communications officer. "We're proud of how well our products have performed in independent testing from reputable third-party organizations such as ConsumerLab.com." This review tested similar eye health products from various nutritional supplement manufacturers to determine whether they in fact contained the right amounts of lutein and zeaxanthin on their labels. The review can be found on the company's website at www.consumerlab.com. In light of new FDA warnings against potentially unsafe supplements available on the market, ConsumerLab.com testing helps consumers and healthcare professionals make better decisions and more informed recommendations when it comes to supplements. "There is a lot of research and development that go into each of our products. Lutein and zeaxanthin are crucial for eye health—that's why they are essential ingredients in Visionex," states Dr. Carsten Smidt, USANA vice president of research and development. "We use the highest quality ingredients possible, and we have pharmaceutical quality protocols in place that guarantee potency and purity."
