Smoothie King is marking National Smoothie Day with a free smoothie offer and a new fast food menu expansion built around summer hydration and lighter meal options.

PRNewswire reported that new and existing Healthy Rewards members can get a free 12-ounce Hydration Watermelon Smoothie on June 21 at participating Smoothie King locations nationwide. 

The offer is tied to National Smoothie Day and comes as the company rolls out new protein-packed Chicken Flatbreads.

A free smoothie and new flatbreads

According to Smoothie King, the Hydration Watermelon Smoothie includes electrolytes and is part of the chain’s summer watermelon lineup. Other seasonal options include The Activator Recovery Watermelon, Gut Health Greek Yogurt Watermelon, X-Treme Watermelon, and Power Meal Slim Watermelon smoothies. 

Three new Chicken Flatbreads are also joining the menu. Visitors can choose Chicken Chipotle, Chicken Ranch, or Chicken Pesto. Smoothie King states that each one includes grilled chicken, tomatoes, cheese, and sauce in a lightly toasted flatbread. Plus, each flatbread has 15 grams of protein and is 270 calories or less. 

For customers watching calories, blood sugar, cholesterol, or blood pressure, it’s still smart to check the full nutrition details before ordering. Better-for-you food can still vary a lot once sauces, sodium, and portion size enter the picture.
