''Can a Brain Pill Make You a Better Chess Player?''; 2005 US Open Chess Masters Get a Sin City View of the New Cognitive Supplement That Helps Them Think Faster!

LOS ANGELES -- Natrol Inc. (NASDAQ:NTOL) Chess masters and fans at the 2005 US Open Chess Championship will get a sneak preview of Natrol(R) brainSpeed(TM), the new cognitive health supplement designed to help improve mental agility, promote attention and maintain memory.(a) This innovative nutritional product hits the chess world June 11, 2005 at the famed Riviera Hotel grand ballroom. In a twist on chess tradition, Natrol and the US Chess Federation will present the brainSpeed Human Chess Challenge, a regulation match where two world-famous Grandmasters control a gigantic chessboard featuring human beings as the chess pieces.

Natrol brainSpeed has been developed to take chess players to the next level by targeting the cholinergic system - the key to mental processing speed - by helping to accelerate reaction time, improve decision making velocity and promote mental acuity. US Chess Open attendees are invited to find out for themselves by attending the match and visiting the Natrol table onsite at the Riviera.(a)

According to Beatriz Marinello, President of the US Chess Federation, "Clearly chess is a game of the mind and working at the top of your mental processing powers is critical to tournament play. We are delighted to be embarking on this alliance with Natrol and we see a direct connection between brainSpeed and our membership. We look forward to many unique events together in the future."

The human chess pieces will also issue brainspeeding tickets to attendees, inviting them to take the brainSpeedOmeter(TM) online test to measure their current mental agility. This test establishes a brainSpeed benchmark for attention, memory and mental performance and then allows people to track their progress as they use the product. The product will also be made available for sales during the Open before its official retail launch in August.
