While Jamba Juice promotes a healthy image, many of its smoothies contain significant amounts of added sweeteners, sherbet, and fruit juice concentrates that drive up the sugar count. The key to finding a truly low-sugar option lies not just in scanning the menu, but in knowing what to ask for and where to look. While an exact single 'least sugar' smoothie is hard to pinpoint due to customizations, certain categories and strategies stand out as the best choices.
The Absolute Lowest Sugar Options
For the absolute lowest sugar item on the menu, your best bet is to bypass the smoothies entirely and head for the Wellness Shots. These concentrated shots of nutrient-dense ingredients offer minimal sugar with maximum flavor and health benefits.
Wellness Shots
- Ginger Shot: Featuring a blend of ginger, lemon, and cayenne, a single 2 oz Ginger Shot contains just 3 grams of sugar. It’s an excellent low-sugar choice for a quick health boost.
- Turmeric Shot: Similar to the ginger shot, the Turmeric Shot also contains only 3 grams of sugar per 2 oz serving.
The Best Low-Sugar Smoothie Categories
If a full-sized smoothie is what you crave, focus on categories designed with lower sugar in mind and be ready to customize.
Kids' Menu Smoothies
Choosing a Kids' size (typically 9.5 oz) automatically reduces sugar and calories by limiting the portion size. Many of the kids' options are simply scaled-down versions of popular flavors. The Kids Strawberry Gone Bananas Smoothie, for example, contains a manageable 30 grams of sugar for a satisfying treat.
Fruit & Veggie Smoothies
This category is a good starting point for lower sugar. These blends often incorporate vegetables like kale, carrots, and spinach, which add nutrients and fiber without excessive sugar, especially when customized.
- Berry UpBEET: A 16 oz Berry UpBEET smoothie contains 38 grams of sugar, which is lower than many classic, fruit-heavy options. It includes strawberries, blueberries, and a mixed berry juice blend, balanced with a red vegetable juice blend.
- Apple 'n Greens: The Plant-Based Apple 'n Greens smoothie, while still containing natural fruit sugars, offers a better nutrient profile than many classics, with 42.2 grams of sugar in one serving.
“Make It Light” Classics
For many classic flavors, Jamba offers a “Make It Light” option. This replaces the higher-sugar frozen yogurt or sherbet with a lower-calorie, artificially sweetened dairy base. This modification can reduce the overall sugar content significantly.
Customizing Your Order for Even Less Sugar
For maximum sugar control, take matters into your own hands with these customization tips:
- Downsize Your Order: Simply choosing a smaller size is the most effective way to cut down on sugar intake.
- Substitute the Base: Ask for a lower-sugar base like unsweetened almond milk or water instead of fruit juice blends.
- Remove Sherbet and Frozen Yogurt: These ingredients are major sources of added sugar in classic smoothies. Request their removal.
- Add Fiber and Protein: Incorporate boosts with fiber and protein, such as chia seeds, oats, or Greek yogurt, to increase fullness and help control blood sugar spikes.
- Amplify the Veggies: Ask for an extra scoop of spinach or kale to increase nutrients and fiber without adding sugar.

For the bare minimum in sugar, the Wellness Shots are the clear winner. For a lower-sugar smoothie, start with a Kids' size, a Fruit & Veggie blend, or the "Make It Light" version of a classic.
