The Dr. Smoothie Classic Lemonade 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 Classic Lemonade has white grape juice, lemon juice (not from concentrate) and pear juice 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.
