Canada's most cherished whey protein, recognized as the top seller, is now evolving to meet your on-the-go needs. Introducing the groundbreaking Diesel Protein Bar, made from premium New Zealand Whey Protein. This isn't just another protein bar, it's an experience crafted from the purest of sources. New Zealand, with its favorable climate and bountiful sunshine, allows cattle to thrive and graze freely. These cattle spend a remarkable 90% of their time outdoors, feeding on the rich, natural grass. This results in a dairy quality that is unparalleled, and Diesel captures this essence in every protein bar.

And, while you might be powering up, you won't be loading on excess calories. Each bar is carefully balanced to offer just 190-210 calories. But that's not all! Dive into a world of flavors with 6 delectable choices. Whether you're in the mood for classic tastes or looking to explore new sensations, there's a Diesel bar waiting to tantalize your taste buds.
