Feeling Fatigue? Power Up with Kiwi

  • Did You Know

When you want a quick boost, your first thought is probably turning to caffeine, right? Sure, you drink coffee for a jolt of instant gratification but what if there was a healthier alternative—say, naturally upping your vitamin C intake? Look no further than kiwi C—or vitamin C from Zespri™ SunGold™ Kiwifruit. 



According to a 4-week study conducted in September 2020, eating 2 Zespri SunGold Kiwifruit per day could benefit your overall vitality, making you feel less fatigued, increase activity and improve mood.1 Here’s how researchers came to these findings:  

  • 167 young adult participants with low vitamin C levels were split into 3 groups:

Following the 4-week period, researchers enacted a “washout period,” or window, to see if any patterns continued despite no daily kiwifruit, vitamin C tablet or placebo pill intake.  

Here’s what they found: the individuals who consumed 2 Zespri SunGold Kiwifruits reported notably better moods, energy levels and overall well-being, not only during the study but during the post-study break as well.  

Researchers concluded that getting nutrients, such as vitamin C, directly from complete food sources like SunGold Kiwifruit provides more health benefits than getting them from supplements alone. That’s likely because many whole foods, including Zespri SunGold Kiwifruits, have a full nutrient package with key nutrients like fiber, folate and potassium.2  


A recent study of vitamin C intakes on more than 84,000 Americans collected over a 20-year period found that vitamin C intakes are on the decline—a 22.6% decrease in vitamin C levels to be exact.3 This is driven in part by the finding that Americans are eating less whole fruit as a source of vitamin C.  

This doesn’t have to be the reality, though, for you. Eating just one SunGold Kiwifruit provides 100% of your daily vitamin C needs!2 And, a single serving of 2 Zespri SunGold Kiwifruits has you more than covered, providing more vitamin C than a single medium orange can offer!2,* Zespri SunGold Kiwifruit is considered one of the premier sources of vitamin C.  

If you haven’t tasted Zespri SunGold Kiwifruit, you’re in for a sweet treat! The unexpected refreshingly sweet flavor delights tastebuds at first bite. Not only is Zespri SunGold Kiwifruit full of unexpected flavor, but it’s easy to eat—just cut, scoop and enjoy!  

You can also eat its smooth outer skin to almost double the fiber content per serving, along with scoring 34% more folate and 32% more vitamin E.4 Go for it; bite right in! New research also suggests eating the skin and flesh of SunGold Kiwifruit together has added beneficial effects on digestive health that are not seen when just eating the flesh alone!5

Ready to re-energize, caffeine-free? Here’s where you can pick up Zespri SunGold Kiwifruit or have fun trying out kiwi recipes that not only taste good, but are good for you, too!
