Vitamin Water poster boy; 50 Cent is launching his own range of dietary supplements.

The rapper has already set up his own 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 CENT has also attacked rival Lil' Wayne and Interscope Records boss Jimmy Iovine in two new mixtape tracks.

50 debuted Part Time Lover and South Side on U.S. radio shows last week. To watch the latest MTV News bulletins click on the VIDEO link above 'Archna Sawjani'
