Refreshers have become a popular menu item at coffee shops like Starbucks and Dunkin' for their fruity flavors and lighter feel compared to coffee. For many, they seem like a better, more natural energy option. But is that really the case? The energy kick from a refresher comes from a blend of stimulating and sugary ingredients, rather than from whole, natural sources. Understanding these components is key to deciphering the kind of energy you'll get and what potential side effects to look out for. While they do offer an energy boost, it's different from what you get from other beverages and comes with its own set of nutritional trade-offs.
The caffeinated core: Green coffee extract
Unlike traditional coffee, which gets its kick from roasted and brewed beans, refreshers contain green coffee extract. This extract is derived from unroasted coffee beans, preserving certain compounds like chlorogenic acid and providing caffeine without the intense coffee flavor. The caffeine content in a standard Refresher is moderate, often comparable to a can of soda but significantly less than a standard brewed coffee.
Here's what you need to know about this key ingredient:
- The green coffee extract is present in the pre-made flavor base of the drinks.
- This means all standard refresher flavors contain caffeine unless a custom order is made with a caffeine-free base, such as Passion Tango tea.
- Because the beans aren't roasted, the resulting extract is milder in flavor, which is why refreshers don't taste like coffee.
The other side of the energy equation: Sugar
Beyond caffeine, sugar is a major contributor to the energy boost from refreshers. For instance, a grande Strawberry Açaí Refresher from Starbucks can contain over 20 grams of sugar, and this can be even higher depending on customizations. This provides a quick hit of energy, followed by an inevitable crash as blood sugar levels drop. This sugar rush-and-crash cycle is a hallmark of many sweetened energy drinks.
Refreshers vs. other popular beverages
Comparing the energy provided by refreshers to other common drinks reveals distinct differences in potency and effect. The following table contrasts a 16-ounce Refresher with other popular options to help you understand where it fits in the energy spectrum.
| Beverage | 16 oz Caffeine (mg) | Main Energy Source(s) | Energy Profile |
|---|---|---|---|
| Starbucks Refresher | ~45-55 mg | Caffeine (green coffee), Sugar | Moderate lift, potential sugar crash |
| Dunkin' Refresher | ~66 mg | Caffeine (green tea), B Vitamins, Sugar | Moderate lift, potential sugar crash |
| Starbucks Iced Coffee | ~165 mg | Caffeine (roasted coffee) | Stronger, more sustained alertness |
| Regular Soda | ~34-42 mg | Sugar, Caffeine | Mild, short-lived boost with a crash |
| Typical Energy Drink | ~72-80+ mg | High Caffeine, Sugar, B Vitamins, Ginseng | Intense rush, possible jitters, definite crash |
Potential side effects and healthier alternatives
While refreshers offer a pleasant alternative to heavier, syrupy energy drinks, they aren't without their drawbacks, especially due to their sugar content. Excessive sugar intake is linked to weight gain, dental problems, and an increased risk of type 2 diabetes and heart disease. Some individuals, particularly those sensitive to caffeine, may still experience side effects like anxiety, insomnia, or an increased heart rate, even from the moderate amount in a refresher.
For those seeking a healthier, more sustained energy boost, several alternatives exist:
- Matcha: A concentrated form of green tea powder, matcha provides caffeine alongside L-theanine, an amino acid that promotes a calmer, more focused alertness.
- Green Tea: Contains a moderate amount of caffeine and antioxidants, offering a gentle, steady energy lift.
- Water with Lemon and Mint: Simple hydration can be a powerful energy booster, as even slight dehydration can cause fatigue.
- Kombucha: This fermented tea contains probiotics that support gut health and offer a small amount of natural energy from B vitamins and caffeine.
The takeaway on refreshers and energy
Do refreshers give you energy? Yes, but the energy comes from two main sources: a moderate dose of caffeine from green coffee or green tea extract and a potentially high amount of sugar. The result is a lighter, fruitier alternative to traditional coffee and high-intensity energy drinks, but it still has a notable stimulating effect. For the average adult, a refresher provides a quick and flavorful pick-me-up, but it is important to be mindful of the added sugar and caffeine content, particularly for children or individuals with caffeine sensitivities. Choosing a healthier alternative like plain green tea or a hydrating fruit-infused water offers a cleaner energy boost without the added sugars and potential crash.
Conclusion
In conclusion, refreshers are a viable option for a mild energy lift, but their effectiveness depends on the individual's caffeine tolerance and sugar sensitivity. While the green coffee or tea extract provides a moderate stimulating effect, the high sugar content can cause an energy spike and subsequent crash. Understanding the ingredients allows for a more informed choice, enabling consumers to either enjoy refreshers in moderation or explore healthier, more natural alternatives for a sustained boost.
