According to this Reuters report, a tablet called Game Suppli has been created designed to pep up the eyes and brains and the country's gaming hardcore.
"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.
Just take crack, Japan. It might not do your gaming much good, but at least it'll have an effect.
