Overview
Smoothie King is an American smoothie franchise brand operated by Smoothie King Franchises Inc. The company specializes in made-to-order smoothies and related health-oriented food and beverage products, serving customers primarily through franchised retail locations. It was established in 1973 in Kenner, Louisiana, by Steve and Cindy Kuhnau. The founders developed the business around blended beverages positioned as more functional and nutritionally purposeful than conventional soft drinks and desserts. Over time, the chain expanded its menu to include fruit- and vegetable-based smoothies, protein and meal-replacement options, supplements, bowls, and selected food items. The brand’s early development was closely associated with the Kuhnaus’ interest in nutrition and the practical use of blended drinks. One of its best-known legacy products, the Hulk smoothie, was created as a high-calorie beverage for a neighbor undergoing chemotherapy who needed help regaining weight. Although Smoothie King increasingly emphasized healthier formulations, the Hulk remained an important and recognizable product in the company’s portfolio. Smoothie King began international franchising in the early 2000s. Its first overseas market was South Korea, where franchisee Wan Kim rapidly developed the concept and opened more than 100 locations within several years. Kim acquired Smoothie King from the Kuhnaus in 2012. The transaction was accompanied by approximately US$58 million in growth capital from Standard Chartered Private Equity and the National Pension Fund of Korea. His expansion plan called for substantial growth in both franchised and company-operated stores, as well as menu development influenced by the South Korean business, where salads and wraps represented a meaningful share of sales. During the 2010s, Smoothie King broadened its geographic footprint while maintaining a predominantly U.S. presence. The company relocated its headquarters from the Louisiana area to Metairie in 2012 after receiving state and local incentives, and it was later based in Coppell, Texas. The chain reached its 1,001st store in 2018 and had more than 1,100 locations by 2020. It has also operated in the Cayman Islands and Trinidad and Tobago, while its earlier Singapore business closed in 2016. Management has historically shown caution about expansion into cold-weather markets, citing the difficulty that smoothie concepts can face in those regions. The company’s positioning changed materially in the late 2010s. Through its Clean Blends initiative, Smoothie King promoted recipes using whole fruits and vegetables and sought to reduce or eliminate food coloring, artificial flavors, preservatives, and added sugar in selected products. In 2023, the brand continued this direction by removing syrups from its products, adding fully organic vegetables, and introducing smoothie bowls. The changes were intended to appeal to consumers, particularly younger customers, who were more attentive to ingredient transparency and perceived healthfulness. The company has nevertheless retained indulgent and high-calorie options, illustrating the tension between its wellness positioning and the breadth of its menu. Smoothie King also increased its visibility through sports and venue marketing. In 2014, it entered a naming-rights agreement with the New Orleans Pelicans, renaming New Orleans Arena as the Smoothie King Center. Products sold under the partnership are tested for compliance with NBA banned-substance rules. In 2025, San Francisco-based Main Post Partners acquired a minority interest to support the company’s next phase of growth. Smoothie King remains an active, privately held franchise business whose core identity combines convenience, customization, functional nutrition, and a better-for-you alternative to traditional quick-service beverages.
History
Smoothie King began in 1973 in Kenner, Louisiana, where Steve and Cindy Kuhnau established a business centered on blended beverages with a nutritional purpose. The company developed a distinctive position between traditional fast food, juice bars, and supplement retailers. Its menu included fruit-based drinks, protein formulas, and high-calorie beverages intended for specific nutritional needs. The Hulk became one of the most recognizable examples of this approach after being created for a neighbor undergoing chemotherapy who needed assistance regaining weight. The chain expanded through franchising and entered international markets in the early 2000s. South Korea became its most significant early overseas market. Franchisee Wan Kim developed more than 100 Korean locations within several years, giving him substantial experience with the brand and its operating model. In 2012, Kim acquired Smoothie King from the Kuhnaus. The acquisition was supported by roughly US$58 million in capital from Standard Chartered Private Equity and the National Pension Fund of Korea. Kim proposed major U.S. expansion, including hundreds of additional franchises and company-operated stores, while also broadening the menu with products such as salads and wraps. The company moved its headquarters from the Louisiana area to Metairie in 2012 after receiving approximately US$2.4 million in incentives. By August 2021, its headquarters location was reported as Coppell, Texas. Smoothie King remained primarily a U.S. chain but also operated in South Korea, the Cayman Islands, and Trinidad and Tobago. Its Singapore operation opened in December 2012 and closed permanently in 2016. The company’s store base passed 1,000 locations in 2018 and exceeded 1,100 by 2020. In the late 2010s, Smoothie King began a more explicit ingredient and wellness repositioning. Its Clean Blends initiative promoted whole and unmodified fruits and vegetables and reduced reliance on food coloring, artificial flavors, preservatives, and added sugar. This was partly a response to growing consumer interest in clean labels and functional nutrition, although the chain continued to sell calorie-dense products. The company’s menu evolution continued in 2023, when it removed syrups, added organic vegetables, and launched smoothie bowls. The bowls were described as commercially successful and helped the brand broaden its consumption occasions. Marketing and corporate development also shaped the brand. In 2014, Smoothie King secured naming rights for the New Orleans Pelicans’ home arena, creating the Smoothie King Center. The agreement connected the brand with professional basketball and required annual testing of products for NBA prohibited-substance compliance. In 2024 and 2025, the company added senior technology, marketing, and finance leadership. In July 2025, Main Post Partners acquired a minority stake to support further growth. Smoothie King therefore remains an active private franchise company combining national scale with a wellness-oriented brand promise and a broad, sometimes nutritionally varied menu.

Products and positioning
A health-oriented quick-service beverage and franchise brand focused on customizable smoothies, whole-food ingredients, functional nutrition, and convenient meal or snack occasions.
Smoothie
Fruit smoothies
Fruit smoothies are a core part of Smoothie King’s menu and form the foundation of its identity as a blended-beverage chain. Recipes combine fruit with liquids, sweeteners, nutritional ingredients, or other additions depending on the formulation. The brand’s later Clean Blends positioning placed greater emphasis on whole fruits and reduced artificial ingredients and added sugar in selected recipes.
High-calorie smoothie
The Hulk
The Hulk is a high-calorie smoothie created during the company’s early years for a neighbor undergoing chemotherapy who needed help regaining weight. It represents Smoothie King’s original functional-nutrition orientation and has remained a notable product associated with the brand. Its calorie-dense formulation contrasts with the company’s later emphasis on lighter, cleaner-label menu choices.
Smoothie
Peanut Power Plus Grape
This smoothie combines peanut butter, banana, sugar, and grape juice. Its large serving was criticized by the Center for Science in the Public Interest in 2013 for its reported calorie and sugar levels. The product illustrates the range of Smoothie King’s menu, which has historically included both wellness-oriented beverages and highly indulgent, energy-dense options.

Clean Blends smoothies
Clean Blends is a menu initiative rather than a single beverage.

The initiative helped reposition Smoothie King toward ingredient transparency and perceived healthfulness while preserving the convenience of a quick-service format.
Bowl · 2023
Smoothie bowls
Smoothie bowls extend the brand beyond drink-only occasions by presenting blended fruit and vegetable bases in a spoonable format with toppings or additional ingredients. Smoothie King introduced the category as part of its 2023 menu changes, alongside the removal of syrups and increased use of organic vegetables. The company reported that the bowls performed profitably.
Food · 2012
Salads and wraps
Salads and wraps were included in expansion plans following Wan Kim’s 2012 acquisition.
