A Diet Coke instead of a multivitamin?

NEW YORK (CNNMoney.com) -- Coca-Cola plans to launch a new version of Diet Coke in 2007 that is fortified with vitamins and minerals, according to a report published Friday.

Diet Coke Plus, slated for a spring launch, will be the first nutrient-enhanced carbonated soda to be offered by a major brand, said Beverage Digest.

A Coca-Cola representative would not confirm the report, but he did not deny it.

"We're always looking to innovate around existing brands," he said. "And we're also looking at new opportunities."

"We'll have lots of news to share on the innovation front in 2007," he added.

Next year, rival Pepsi (Charts) will introduce a line of enhanced carbonated drinks called "Tava," said the report.

Shares of Coca-Cola (up $0.15 to $48.87, Charts) traded up 0.3 percent on the New York Stock Exchange Friday.
