How Many Calories Are In Mozzarella String Cheese? | Smart Snack Facts

Mozzarella Sticks Calories: What One Stick Contains

Most single sticks of low-moisture, part-skim mozzarella land around 80–90 calories per 28 g serving, with 6–7 g of protein and minimal carbs. Brand labels show small swings due to fat content and moisture differences. For instance, a common grocery brand lists 90 calories with 7 g protein per stick, while some organic options show 80 calories with the same protein. These numbers come straight from product nutrition panels and government-sourced vendor labels that package the same serving size.

Quick Table: Brand Snapshot (Per 28 G Stick)

This overview pulls from current product pages or published vendor labels. Use it as a starting point, then match to the package you buy.

Brand (Type)	Calories	Protein
Sargento (part-skim)	90	7 g
Horizon Organic (part-skim)	80	7 g
Borden (part-skim)	80	7 g
Sargento Light (reduced-fat, 21 g stick)	45–50	5–6 g

Labels can differ slightly across seasons or plants, so always cross-check the pack you’re holding. A federal vendor label for low-moisture part-skim string cheese sets a common baseline at 90 calories and 7 g protein per 28 g stick, while several brands list 80–90 calories for the same size.

What Drives The Calorie Differences

Fat Percentage And Moisture

Part-skim recipes shave some butterfat off the cheese curd while keeping texture that still pulls apart cleanly. That tweak trims calories, which is why string snacks tend to sit below blocks of whole-milk mozzarella per ounce. Moisture level matters too: lower moisture concentrates nutrients and fat, nudging the calorie line upward.

Stick Size And Rounding Rules

Most sticks weigh 28 g, but light versions often weigh closer to 21 g. Nutrition panels must follow rounding conventions for grams and milligrams, which can shift the displayed numbers you see on the label a touch. That’s why two labels with the same formulation may not look identical once rounded under 21 CFR 101 labeling rules.

How String Cheese Fits Common Goals

Weight Management

Portion control is baked in. One stick delivers around 80–90 calories and enough protein to take the edge off cravings. If you’re dialing in an energy target, snacks click into place once you’ve set your daily calorie needs. From there, you can swap in a light stick when you want fewer calories or pair a standard stick with fiber-rich produce for a steadier snack.

Protein Intake

Expect 6–7 g protein per stick. That’s similar to a small egg and helps hold you between meals. Pair with nuts, whole-grain crackers, or sliced veggies to round out the snack without sending the calorie count sky-high.

Sodium Awareness

Most labels show roughly 170–200 mg sodium per stick. If you’re watching sodium for blood-pressure reasons, plan the rest of the meal around fresh produce and low-sodium staples to keep the day balanced.

Label Proof: Where The Numbers Come From

Two reliable sources line up on the typical range. A U.S. Department of Agriculture vendor label for low-moisture part-skim string cheese lists 90 calories and 7 g protein per 28 g serving. A major national brand shows 90 calories and 7 g protein on its product page, while an organic brand lists 80 calories with the same protein. These are all standard 28 g sticks. For reduced-fat sticks, brand pages commonly list 45–50 calories for a ~21 g stick, reflecting lower fat and smaller size.

When you compare panels, check serving weight first, then calories, protein, and saturated fat. This avoids apples-to-oranges comparisons between 21 g light sticks and 28 g standard sticks, or between part-skim and whole-milk styles.

Portion Tips And Pairings

Fast Pairings Under ~200 Calories

• 1 stick + 1 small apple
• 1 stick + raw carrots and cucumbers
• 1 light stick + a few whole-grain crackers

When You Need More Staying Power

• 2 sticks + berries for a higher-protein mini meal
• 1 stick + hummus + veggie sticks
• 1 stick + a slice of whole-grain toast

Macro Profile: What You Get Per Stick

String snacks bring protein, calcium, and almost no carbs. Saturated fat varies by style: light sticks trim it, whole-milk sticks raise it. If you want a number to track, stick with calories and saturated fat side by side, since those two swing the most across styles.

Serving Guide And Ranges

Use this simple chart to glance the usual serving sizes, calories, and quick notes for planning.

Serving	Calories	Notes
1 light stick (~21 g)	45–50	Lower fat; smaller size
1 standard stick (28 g)	80–90	Most common size
2 standard sticks	160–180	Mini meal with fruit/veg
Whole-milk style (28 g)	90–100	Richer taste, more fat

How To Read The Panel For This Snack

Start With Serving Weight

Look for 21 g vs 28 g. That difference can shift calories by 30–40. Next, scan calories, protein, saturated fat, and sodium. Panels are built under FDA rules, including rounding conventions for small amounts, so tiny discrepancies between brands can be due to labeling math rather than recipe changes. If you want the rulebook, see the FDA’s Food Labeling resources that outline what must appear on a panel and how numbers are rounded.

Buying Tips And Storage

Pick A Type That Fits Your Target

Go part-skim for the classic 80–90 calorie range. Pick light when calories or saturated fat are your main concern. Choose whole-milk when flavor and melt are the priority and you’re pairing it with lighter sides.

Check Pack Dates And Keep It Chilled

Refrigerate promptly, reseal the outer bag, and use within the window shown by the producer. The individual wrapping helps keep freshness, but quality is best when eaten within a week or two of opening the pack.

Common Questions, Answered Briefly

Is There Carbohydrate In A Stick?

Usually 0–1 g. Lactose is minimal in this style, which is why the carb line stays near zero.

Is This Snack Good For Kids’ Lunches?

Yes—portion control, protein, and easy packing make it a handy lunchbox add. Add fruit or sliced veg to round it out.

What About Calcium?

Many labels list ~15% Daily Value per 28 g stick. That’s a nice boost, especially when dairy intake is low at breakfast or lunch.

Method Notes: How We Compiled The Numbers

We cross-referenced government vendor labels for low-moisture part-skim string snacks with current brand product pages. Government documentation pegs one 28 g stick at 90 calories and 7 g protein. A leading national brand lists the same. An organic brand lists 80 calories with 7 g protein per 28 g. A light, reduced-fat option shows 45–50 calories for a smaller ~21 g stick. These figures match what you’ll see on the package in stores.

If you want the primary sources, compare a USDA vendor label for “mozzarella string cheese, low moisture part skim” with a mainstream brand’s nutrition page, and keep the FDA’s labeling rules handy when you notice small rounding differences.

Make It Work Day To Day

Use one stick as a 80–90 calorie bridge between meals. Pair with produce for fiber. If you’re keeping an eye on saturated fat, rotate in light sticks during higher-calorie days, and use whole-milk versions when the rest of your meal is lean.
