Megan's Mango Protein Refresher is Dunkin's limited-edition drink created in collaboration with Megan Thee Stallion, released as part of Dunkin's 2026 Protein Milk lineup. It blends mango flavor with Dunkin's new Protein Milk base to deliver 15 grams of protein in a medium size, turning a classic fruity Refresher into something that actually holds you over.
If you've seen it on the menu or on TikTok and want the real nutrition breakdown before ordering, this is the full guide: calories, protein, sugar, carbs, caffeine, customization ideas, and how it compares to other Dunkin Refreshers.
Quick Summary
- What it is: a mango-flavored Refresher made with Dunkin's Protein Milk

- Protein: 15 grams (medium)
- Calories: 300 (medium)
- Sugar: 42 g (medium)
- Best for: afternoon pick-me-up, post-workout, or as a lighter alternative to a full meal replacement

What Is Megan's Mango Protein Refresher?
Megan's Mango Protein Refresher is the mango-forward entry in Dunkin's five-drink 2026 Protein Milk line, which also includes the Strawberry Protein Refresher, Caramel Chocolate Iced Protein Latte, Almond Iced Protein Matcha Latte, and Iced Protein Latte with Sugar-Free Vanilla.
The drink pairs Dunkin's fruity Refresher base (green tea extract + fruit flavor concentrate) with Protein Milk, Dunkin's specially-formulated high-protein milk base that adds 15 g of protein per medium drink without obviously changing the flavor profile you already know.
The result is a drink that tastes like a Refresher but is more filling because of the protein and added creaminess. You can read more about how Dunkin's Protein Milk fits across the full menu in our guide to Dunkin's 2026 Protein Milk & new drinks.

Estimated Nutrition by Size
Dunkin typically offers Refreshers in Small (16 oz), Medium (24 oz), and Large (32 oz). The official numbers Dunkin publishes are for the medium, so smaller and larger sizes scale roughly proportionally:
| Size | Calories | Protein | Sugar |
|---|---|---|---|
| Small (16 oz) | ~200 | ~10 g | ~28 g |
| Medium (24 oz), official | 300 | 15 g | 42 g |

How Much Caffeine Is In It?
Dunkin Refreshers are made with green tea extract, not coffee. A medium Refresher typically contains approximately 66 mg of caffeine, well below a medium iced coffee (roughly 198 mg caffeine) but enough for a mild afternoon lift. If you're sensitive to caffeine or choosing an evening drink, this is a lighter option than Dunkin's coffee-based protein lattes.
How It Compares to Other Dunkin Protein Drinks (Medium)
| Drink | Calories | Sugar | Protein |
|---|---|---|---|
| Megan's Mango Protein Refresher | 300 | 42 g | 15 g |
| Strawberry Protein Refresher | 290 | 40 g | 15 g |
| Caramel Chocolate Iced Protein Latte | 280 | 38 g | 15 g |
| Almond Iced Protein Matcha Latte | 260 | 31 g | 15 g |
| Iced Protein Latte w/ Sugar-Free Vanilla | 170 | 13 g | 15 g |

If your priority is protein with the lowest sugar, the Iced Protein Latte with Sugar-Free Vanilla is the clear winner. Megan's Mango is the second-highest in sugar in the lineup, expected for a fruit Refresher, but still gives you the full 15 g protein.
How to Customize It for Lower Sugar
The sugar comes from the mango flavor base, not the Protein Milk. That means you have limited customization options, but a few meaningful swaps:
- Downsize to a small, cuts calories, sugar, and protein roughly one-third (about 200 cal, 28 g sugar, 10 g protein).
- Ask for light fruit flavor base / extra ice, reduces the concentrated syrup dose, cutting sugar modestly.
- Skip Protein Milk, use water or unsweetened almond milk, lowers calories slightly, but you lose the protein, defeating the purpose of this drink.
If low-sugar is your primary goal, a different Dunkin drink (like the Iced Protein Latte with Sugar-Free Vanilla) is a better fit.
Who Is It Best For?
- Post-workout: 15 g protein + carbs = a decent recovery option when you want something cold and fruity instead of a shake
- Afternoon energy dip: lower caffeine than coffee, with fruit flavor and staying power
- Fans of sweet Refreshers who want more staying power, the protein and added creaminess keep you full longer than a regular Refresher
- Fans of Megan Thee Stallion, if you want to try the collab drink, you're in the right place
Who Should Skip It
- People watching added sugar carefully, 42 g of sugar per medium is high relative to the 25 g/day American Heart Association limit for adult women and 36 g/day for men
- People with diabetes or insulin resistance, the carb load (45 g) and rapid-absorption sugars may spike blood glucose. See our diabetes-friendly Starbucks drinks guide for lower-carb coffee-shop alternatives
- People on a strict keto or very low-carb plan, this drink is not keto-friendly. See our keto-friendly Dunkin drinks guide for better options
How to Order It
At the counter or drive-thru, ask for:
"A medium Megan's Mango Protein Refresher, please."
For a smaller, lower-sugar version:
"A small Megan's Mango Protein Refresher with extra ice."
The Dunkin app also lists it under the Refreshers / Protein section. Availability can vary by location, as with most limited-edition collabs, not every Dunkin will stock the flavor all year.
