Osgood and O’Reilly Have Something in Common: brainSpeed™
Radio Heavyweights ask Americans to Think Faster with new cognitive supplement

LOS ANGELES, CA – September 15, 2005 – Natrol Inc. (NASDAQ: NTOL), Radio Hall of Famer Charles Osgood and Radio Factor star Bill O’Reilly are the new voices of a national campaign to encourage Americans to think faster with brainSpeed™, the new cognitive supplement by Natrol. Leveraging the growing media focus on cognitive health trends, Natrol, a recognized leader in the world of nutritional supplements, tapped the media titans as the centerpiece of their Westwood One campaign on the CBS Radio Network. Natrol® brainSpeed™ is an innovative new line of supplements designed to help support mental agility, promote attention and maintain memory.†

“As a journalist I’m always intrigued by new ideas and new concepts in the ways we can process information,” said Charles Osgood, CBS Radio’s Poet-In-Residence. He continued in his trademark verse, “Try it America, try it and see. A faster brain sounds like good news to me.”

Natrol brainSpeed combines essential core nutrients in a proprietary blend that help support the production and activity of acetylcholine. Acetylcholine is a chemical messenger in the brain that affects memory, learning, recall and thought processes. Through a combination of Thiamin, Niacin, Pantothenic Acid, DMAE and Huperzine A, the brainSpeed blend targets the cholinergic system – the key to cognitive speed.†

Natrol also offers an interactive online testing technology, the brainSpeedometer™. It is the first time the effectiveness of a nutritional supplement for cognitive health can be measured on an individualized basis, allowing consumers to establish a benchmark for their mental processing speed and then track their progress as they take the product.
