Smoothie King's Stretch & Flex collagen-infused smoothies were specifically crafted to support join health and flexibility, and they're being promoted in partnership with gold medal gymnast Gabby Douglas. The smoothies, available in Tart Cherry or Pineapple Kale varieties, feature the new Joint Health Enhancer with Collagen, which blends type II collagen. This functional ingredient is said to "increase joint flexibility and mobility and can reduce joint soreness during and after exercise," with daily use.
The line of flexibility-focused smoothies made with collagen were created for active guests who are looking for additional support. As Smoothie King says, "We knew our guests were looking for a smoothie blended specifically for people who love yoga, dance, gymnastics and any activity requiring flexibility. Our new Stretch & Flex smoothies with collagen make us the first to offer a smoothie made with this distinct purpose in mind."
