The Dr. Smoothie Blueberry Banana Concentrate is amazing. All the Dr. Smoothie concentrates have wonderful, natural flavours. Each is vegan and fat-free, gluten-free, lactose-free and has no preservatives, artificial colours, flavours or sweeteners. Instead, they have real fruit sweetened with cane sugar. Every bottle of the Blueberry Banana has the equivalent of 166 blueberries, 12 pears, 1/2 banana and 1/2 apple in it. There’s a reason they’re so darned popular… just add ice, water and a blender for a cool treat! Each bottle holds 46 fluid ounces, and makes 18 eight ounce drinks.
