Natrol Announces MRI Product Line Extension

Natrol, Inc. (Nasdaq: NTOL), a leading manufacturer and marketer of nationally branded nutritional products, announced that it has introduced a new supplement, Black Powder™, under its Medical Research Institute (MRI) brand. Black Powder is a highly potent nitric oxide generating pre-workout formula. Nitric oxide helps dilate blood vessels that deliver muscle building agents, essentially feeding muscles with key nutrients during both workout and recovery. Black Powder provides an enhanced boost of nitric oxide with the use of ACTINOS2IR, the highly concentrated form of the whey-peptide fraction, lab-tested to increase nitric oxide synthase. With this new technology, Black Powder delivers unprecedented concentrations of nitric oxide to enhance athletic performance and to provide greater strength and muscular endurance. Wayne Bos, Natrol’s President and CEO, commented, "This is exactly the kind of innovation that made the MRI acquisition so desirable to us. Black Powder is an excellent line extension that reinforces our premium brand position across the entire MRI portfolio of products. We will continue to invest in a strong research and development effort across all of our brands to ensure that each retains its cutting-edge market position.” MRI, recently acquired by Natrol, was founded in 1997 and supplies high-quality sports nutrition products such as CE2®, NO2®, Pro-NOS™ and Anabolic Switch™, all of which are primarily designed to enhance work-out performance. The MRI brand carries a premier position in the sports nutrition market. The brand identity is underpinned by a reputation for innovative science, as this new product release underlines. Notably, MRI was the first company to launch nitric oxide based products in the sports nutrition market. MRI's products are primarily distributed through GNC.

Now you get the over-whelming advantage of an Instant surge of 950% more nitric oxide, combined with the most scientifically potent pre-workout compounds delivered in ratios measured to precise gram-molecular specification.* The Science: Driving Performance and Size to New Levels Scientifically, nitric oxide forms the basis from both performance and size.

Thanks to MRI's innovative ACTINOS2 IR, Black Powder creates an immediate surge in nitric oxide levels, 950% higher than previously attainable. In an instant, Black Powder's performance/size nutrient complex floods your muscle cells in volumes we never believed possible. Your body's performance and growth signals amplify in intensity, starting at your first set! Your strength, intensity, and focus hit levels they've never known. Your recovery starts before you even leave the gym. That's why with Black Powder, you'll get the most outrageously intense workout of your life, and you'll have the super-dilated skin-ripping pumps to prove it!* (Images / Interviews / Samples Available)
