Smoothie King Summit, Summit

Smoothie King cofounder Steve Kuhnau began mixing fruit, nutrients, and proteins in the late 1960s in a successful attempt to treat his own health conundrums. By 1973, he’d begun selling vitamins alongside his health-boosting concoctions, and soon more than 600 Smoothie King locations were operating worldwide.

Today, the shop’s patrons customize real apple, mango, and banana smoothies with healthy mix-ins. More than 70 blendable multivitamins, minerals, enzymes, nutrients, and amino acids fortify frosty smoothies, helping customers stay healthy or bench-press semi-trucks. Meanwhile, snacks such as veggie chips and high-protein cookies augment shakes in both health and deliciousness.
