Differing from the regular Mars Protein Bars, these bad boys come with super salted caramel layers and overall lower sugar content to get those tastebuds pumping just like you've been doing in the gym. Coming with 18-grams of protein per bar and 196 calories, they're now easier than ever to fit into your daily diet and lifestyle. The balance between sweet chocolate and salty caramel has been absolutely perfected by the confectionary giant in this protein bar.
