American smoothie franchise chain Robeks has broadened its product range with the launch of two new sweet and sour smoothies.

The new offerings, Sweet Sipper and Sour Power, feature a blend of fresh fruits and superfood enhancements, including the superfoods Ashwagandha [a medicinal herb said to decrease cortisol levels and alleviate stress and anxiety] and Ginseng [a plant extract said to improve cognitive function and fortify the immune system].

These additions are designed to both elevate the taste experience and offer notable health benefits to consumers.

The Sweet Sipper smoothie is made from fresh peach, mango, cranberries, lemon, apple juice, orange sherbet, frozen yogurt, Ashwagandha and Ginseng.

The Sour Power combines fresh strawberry, blueberry, lemon juice, raspberry juice, pineapple sherbet, and the same superfood ingredients.

Ashwagandha and Ginseng intensify the distinct sweet and sour flavours, while contributing to stress reduction and immune system support.

In early 2024 Robeks launched new performance-based smoothies enriched with Heart Beet, multivitamins and an advanced whey protein isolate.

These smoothies are tailored to enhance immunity, promote heart health and boost energy.

With a history spanning more than two decades, Robeks is known for its diverse menu including smoothies, juices, acai bowls and premium toasts.

The franchise has successfully expanded its presence to more than 100 operational locations, with an additional 40 in development across 13 US states and the District of Columbia.

Robeks marketing vice-president Mitch Baker said: “Summer is the perfect time to expand on our superfood-enriched offerings, especially as people look to destress and stay healthy. We love offering our fans fresh and flavourful smoothies that serve a dual purpose.

“The Sweet Sipper and Sour Power taste like candy, but have natural nutrients that make you feel energised and chill at the same time.”
