Dr. Avena: Most protein bars, even those marketed as “healthy,” are loaded with sugar, void of nutrients, contain artificial dyes or sweeteners, and can cause trouble for your brain. Brain Boost Bars are different because they are sweetened with allulose, stevia, and monk fruit. Brain Boost Bars have 12 grams of healthy plant-based protein per serving and 11 grams of fiber to help keep you full. We were intentional about what we included — cocoa, almonds and MCT oil powder, which add antioxidants and polyphenols to support brain health.
