50 Cent has announced that he is planning to launch his own range of dietary supplements.

The 'In Da Club' rapper, whose real name is Curtis Jackson, already has a record label, energy drink and clothing line. He will be launching the new venture in conjunction with his new movie, which sees him starring as a boxer.

"I'm getting ready to do a dietary supplement company, so I have a nutritionist and a physical trainer travel everywhere with me," Jackson is quoted by the Evening Echo as saying.

"I'm preparing for a boxing film. I'll be working out with Roger Mayweather, [boxer] Floyd Mayweather's uncle."

50 recently threatened to stop releasing music if his new album Curtis does not outsell Kanye West's Graduation.
