Ocean Spray has launched a line of vitamin-infused energy drinks in the US.

Cranergy Energy Juice Drinks contain real cranberry juice blended with B-vitamins, vitamin C and green tea extract, the company confirmed late last week.

"The launch of Cranergy not only marks our entrance into the energy drink category," says Ocean Spray Chief operating officer Ken Romanzi, "it is the first ever energy beverage to hit the juice aisles."

Priced at around US$4, Cranergy comes in two flavours: Cranberry Lift and Raspberry Cranberry Lift. Splenda sweetened with 35 calories per eight-ounce serving, it will be available next month across the US, in 46oz plastic bottles or 12oz four-packs.

"In developing Cranergy," said Romanzi, "we sought to combine naturally energising ingredients with our popular cranberry juice products to provide a solution for those looking for extra energy while maintaining a healthy, low-calorie diet."
