Soy protein is the main source of protein in our bars. While there are many different types of plant-based protein to choose from, we wanted to include a complete plant-based protein in our snack bars that has high digestibility. This means you don’t need to be concerned with pairing our bars with another protein to get all the essential amino acids your body needs. The soy protein in our products meets Non-GMO Project’s stringent requirements. You can explore more information and find our full list of Non-GMO Project Verified products at www.nongmoproject.org.
