Smoothie King Gladiator Nutrition Facts
The Gladiator is the protein smoothie on the board: their protein blend and fruit, with nothing added to sweeten it. Here is what that adds up to, and how to rebuild it at home.
The Gladiator is Smoothie King’s protein smoothie, built from their protein blend and fruit with no added sugar and no fat, which is why it carries the most protein and the least sugar of anything on the board. Rebuilt at home the same way, a Gladiator style blend runs about 292 to 389 calories a serving, and almost all of it is protein and fruit rather than sweetener. The cup size decides the rest: order it bigger and every line on the label scales with it.

Most smoothies on a chain board are fruit and juice with something sweet stirred through them. The Gladiator is the exception. It is Smoothie King’s protein line, built on their protein blend with fruit and no added sugar, which is the whole reason people look it up separately from the rest of the menu. The protein does the work, the fruit does the flavor, and there is no turbinado or juice blend carrying the sugar line up.
Smoothie King publishes the official panel for each Gladiator flavor on its own nutrition page, quoted for one standard cup. Order it in a larger cup and every figure moves with it, so the drink you looked up and the drink in your hand can be two different sizes wearing one name. The rebuilds below show where the calories and protein actually come from, and our Smoothie King calculator carries the published figure for the Gladiator alongside the rest of the menu. To count a version of your own, the smoothie calorie calculator totals whatever goes in the jar.
A Gladiator, rebuilt in your own blender
One serving each, our own recipes rather than Smoothie King’s. Protein powder and fruit on a light liquid, with nothing added to sweeten it, which is the whole idea of the drink. Make the cup bigger and the numbers rise with it.
What decides where a Gladiator lands
A Gladiator is protein first. Two scoops of protein carry more of the calorie total than the fruit does, and all of the protein. That is the opposite of a fruit classic, where the fruit and the sweetener run the label. It is also why the Gladiator reads heavier than a plain fruit cup while being the better drink for holding you until the next meal.
The Gladiator lists no turbinado, no honey and no juice blend, so the only sugar in it is what the fruit brings. Swap the fruit for a tarter one and the sugar line drops further. This is the single thing that separates it from almost everything else on the board.
Every official figure is quoted for one standard cup. Order the same Gladiator in a larger one and the recipe scales with the volume, protein included. The bigger cup is a bigger drink, not a better one, and it is the most common reason a Gladiator comes in heavier than the number someone looked up.
Strawberry, chocolate, vanilla and mango ginger are close on the label because the protein blend is the same in all of them. The fruit or the cocoa shifts the taste far more than it shifts the numbers, so pick the flavor you want and let the size and the add-ins be where you actually control the total.
The Gladiator is lean until you start adding to it. A nut butter enhancer or an extra scoop is easy to wave through and it undoes the thing that made the drink worth ordering. If you want it to stay a Gladiator, keep it to the protein and the fruit.
How to order it, or make it at home
The simplest lever is the size. Ordering the cup the published figure is quoted at keeps the drink you get matched to the drink you looked up, and the only thing you give up is volume.
The Gladiator earns its place by being protein and fruit with nothing extra. A nut butter or an extra sweet enhancer turns it into a different drink, so leave them off unless you have planned the calories around them.
At home a Gladiator is two scoops of protein, a cup or so of frozen fruit and a light liquid. Water or unsweetened almond milk keeps it lean, and the frozen fruit does the thickening so you need no ice. Run yours through the calorie calculator to see the exact glass.
For the figure Smoothie King states for a specific flavor and size, read it on their own nutrition page or in the Smoothie King calculator, which carries the published Gladiator numbers next to the rest of the menu.
