Smoothie King offers a variety of smoothies, and whether they contain dairy or not depends on the specific product and the options chosen by the customer. For those who prefer dairy-free options, Smoothie King provides several smoothies that can be made without dairy ingredients. Customers can also request alternative bases, such as almond milk or coconut milk, to substitute for traditional dairy products. Additionally, many of the smoothie ingredients, like fruits and vegetables, are inherently dairy-free. It is important for customers to carefully read the ingredient list or ask staff about specific smoothies to ensure they meet their dietary preferences or restrictions.
