Every green-smoothie fear, answered with printed numbers: the Green Machine blends mango, pineapple, and a boost of greens into 20g of protein in Bolingbrook.

Type "green smoothie" into a search bar and you get two kinds of results: recipes that taste like a lawn, and juices wearing a healthy costume. The Green Machine — our green smoothie in Bolingbrook — is neither. It's sweet mango and juicy pineapple with a boost of greens, 20g of protein, and every number printed on the menu before you spend a dollar.

The fear, handled first

Nobody's actually afraid of greens. They're afraid of a $10 cup that tastes like the bag the spinach came in.

So here's the honest description: the Green Machine leads with mango and pineapple. The greens are a boost, not the flavor — they ride along while the fruit does the talking. It drinks tropical and refreshing, and our menu tags it not-too-sweet, which is exactly where a green smoothie should sit. If you've been burned by a grassy one somewhere else, this is the one to reset on.

What's actually in the cup

Every Fuel Up smoothie is built the same way: blended on water and ice, never milk or yogurt, with real fruit and our protein blend doing the work. The Green Machine adds its boost of greens to that base — no mystery scoop, no "proprietary wellness blend" hiding the details.

And the details are printed, not promised. Right on the menu:

  • 20g of protein
  • 10g of fiber
  • Under 300 calories
  • No added sugar

The 24 oz is $10.25. That's the whole transaction: you can read every number that matters before you order, which is more than most "green drinks" will show you.

Why the numbers beat the color

Green doesn't mean healthy. Plenty of green drinks are juice with a costume — concentrated sugar, almost no fiber, and you're hungry again in an hour.

Don't take our word for it. Johns Hopkins' guide to building a healthy smoothie makes the same two points our menu is built on: whole fruit beats juice because juice concentrates the sugar and drops the fiber, and protein is what keeps a smoothie from being a snack you forget by 10 AM.

That's why the fiber line matters here. The Green Machine is one of three smoothies on our board carrying a full 10g of fiber — Mango Pineapple and Dragon Fruitty are the other two — while the berry blends come in at 5g. Add 20g of protein and you have a drink that behaves like food, not like juice.

When 20 grams isn't enough

Training day? The 32 oz Muscle upgrade takes the Green Machine to 32g of protein — BCAAs plus 12g of extra protein for $13.35.

One thing we say plainly every time: the upgrade's whey and casein isolate are milk-derived. The smoothie as poured is dairy-free; the Muscle version is not. Your call, made with the facts in front of you.

The part a home blender can't copy

Here's the thing about trying to recreate this cup at home: the fruit is the easy half. What you can't eyeball is the rest — a protein blend that carries 20g without wrecking the flavor, fiber that lands at a full 10g, and a balance tuned so the greens read as tropical instead of grassy, all of it finishing under 300 calories with zero added sugar.

That's a formula, not a shopping list. It's why the "I'll just make it myself" version usually comes out as a different drink — thinner, sweeter, or green in the way nobody wants. The original is $10.25 for the 24 oz, with every number already counted and printed before your first sip.

Where it fits on the board

Think of the Green Machine as Mango Pineapple's twin that went to the gym's salad bar — same tropical fruit, same 20g of protein and 10g of fiber, plus the greens boost. If you want the fruit without the greens, Mango Pineapple is your order. Dragon Fruitty rounds out the 10g-fiber trio; the berry blends run lighter at 5g. Training day, the Muscle upgrade takes any of them to 32g.

And since every base is water and ice, there's nothing to substitute if you're skipping dairy — just flag a true allergy with the team when you order. Line all six up and pick the smoothie that matches your macros before you park.

Questions we get asked

Does the Green Machine taste like vegetables?

No — it's sweet mango and juicy pineapple with a boost of greens, and it drinks tropical, not grassy. It's even tagged not-too-sweet on our menu, for people who want refreshing without the sugar bomb.

What are the macros on your green smoothie?

20g of protein, 10g of fiber, under 300 calories, and no added sugar — printed on the menu next to the Green Machine. The 24 oz is $10.25.

Can I make it stronger for training days?

Yes — the 32 oz Muscle upgrade adds BCAAs plus 12g of extra protein for 32g total, at $13.35. One heads-up: the added whey and casein isolate are milk-derived, so skip the upgrade if you want the smoothie dairy-free as poured.

Is a green smoothie enough for breakfast?

With 20g of protein and 10g of fiber, the Green Machine is built to keep you full and satisfied longer — not hungry again in an hour. We open at 6 AM on weekdays, so it's ready before your commute is.
