Prana Snacks is launching an on-the-go snack format of its popular Kilimanjaro trail mix, which includes 70% dark chocolate with crunchy organic nuts and naturally sweet dried fruits. The company says the mix is a "good source of antioxidants such as vitamin E, selenium and magnesium." Prana's single-serve trail mix will be sold in 45-gram bags when it hits stores shelves in March.Launching a product? Tell us about it.
