Rockin' Refuel, a brand of Phoenix-based Shamrock Farms, debuted its latest flavor innovation – Salted Caramel – exclusively in 7-Eleven stores nationwide. The flavor is unique to the protein drink category and complements the rest of Rockin' Refuel's product line, the company says.  Salted Caramel joins Chocolate and Vanilla as part of Rockin' Refuel's Muscle Builder line of beverages that are designed to deliver high-quality protein, low sugar and low carbs to active adults.

"The first-of-its-kind Salted Caramel flavor was developed as a result of feedback from fans and professional athletes and is the latest example of the brand’s commitment to providing the best-tasting protein drinks on the market," said Blake Atkinson, director of brand management for Shamrock Farms, in a statement. "Our goal is to lead the category in providing healthy and delicious protein beverages that are made with real milk and help people achieve their fitness goals."

 Salted Caramel Muscle Builder offers 30 grams of protein and nine net grams of carbs and is formulated specifically to help build muscle and strength, the company says. Its 12-ounce packaging makes it a convenient on-the-go option to drink before or after a workout or as a quick meal replacement, it says. The performance beverage also is lactose free.
