For all of those who have suffered gaming fatigue - the bleary eyes and aching fingers - a Japanese company says it has come up with something to keep you playing.

Game Suppli is a new Japanese supplement developed specifically for gaming fanatics.

"We concentrated on developing a supplement for those who love games", reads the advert for the pills on, a website that sells a range of gaming accessories.

According to Reuters, the company behind the supplements - Kyowa-Yakuhin - produces two different supplements: there are blueberry tablets that are meant to be good for the eyes, and transparent capsules containing Docosahexaenoic acid, or DHA, which is a fatty acid that supposedly enhances concentration.

Pop a couple and you could play 'til your hands fall off (which the company probably has a remedy for too).
