TOKYO, JAPAN - Gaming addicts with sore eyes and tired brains may be able to perk up with "Game Suppli," a new Japanese supplement developed specifically for the country's thousands of fanatic players.

"We concentrated on developing a supplement for those who love games," reads the advert for the pills on www.cybergadget.co.jp, a Web site that sells a range of accessories for video game fans.

Maker Kyowa-Yakuhin produces two different supplements for the "Game Suppli" range: blueberry tablets that are meant to be good for the eyes, and transparent capsules containing Docosahexaenoic acid, or DHA, a fatty acid that supposedly enhances concentration.

Japan's convenience stores are stacked with drinks and capsules claiming various health and beauty benefits, sometimes without any scientific evidence. --REUTERS
