The Unsurpassed Champion: Kakadu Plum
The Kakadu plum, a small, green fruit native to Australia, holds the title for the highest concentration of vitamin C. This fruit can contain up to 2,907 mg of vitamin C per 100 grams, significantly more than an orange. Its high vitamin C content, along with other phytochemicals, contributes to its potent antioxidant capacity, making it a valuable superfood traditionally used by Indigenous Australians for its medicinal and nutritional benefits. Due to its tartness and perishability, it is commonly consumed as a powder or extract outside of Australia. It also provides other nutrients like vitamin E, zinc, and iron.
Runners-Up in the Vitamin C Race
Beyond the Kakadu plum, several other fruits offer exceptionally high vitamin C levels.
The Mighty Acerola Cherry
The acerola cherry, a small, tropical fruit, is another excellent source of vitamin C, providing up to 1,650 mg per 100 grams. Rich in polyphenols and flavonoids, acerola has strong antioxidant and anti-inflammatory properties. Its vitamin C is considered highly bioavailable, and it's often used in powders, juices, and supplements.
The Amazonian Camu Camu Berry
Camu camu, a berry from the Amazon rainforest, is also notably high in vitamin C, with content varying by ripeness and reaching up to 2,280 mg per 100 grams. Like the Kakadu plum, its acidity means it's usually consumed as a powder. Camu camu also contains beneficial antioxidants like flavonoids and anthocyanins.
Other Potent Fruit Sources
Several other widely available fruits provide significant vitamin C. A guava contains around 125 mg, black currants offer 102 mg per half-cup, and a cup of strawberries has 97 mg. Including a variety of these fruits helps ensure consistent vitamin C intake.
The Health Benefits of Fruit-Based Vitamin C
Getting vitamin C from whole fruits offers numerous health advantages.

Why Choose Food Sources Over Supplements?
Consuming vitamin C from whole fruits is generally preferred over supplements due to the synergistic effects of the complex mix of vitamins, minerals, and phytonutrients found in fruits. Bioflavonoids in fruits, for instance, can improve vitamin C absorption and utilization. Whole fruits also provide essential dietary fiber not found in most supplements. For most individuals with a balanced diet, the body efficiently absorbs sufficient vitamin C from food.
How to Incorporate Vitamin C-Rich Fruits into Your Diet
Boosting your vitamin C intake with these fruits can be simple and delicious:
- Smoothies: Add acerola cherry or camu camu powder to smoothies for a nutrient boost.
- Snacks: Enjoy fresh guava, strawberries, or kiwi on their own or in a fruit salad.
- Toppings: Sprinkle Kakadu plum or camu camu powder on yogurt or oatmeal.
- Flavored Water: Infuse water with orange or lemon slices.
- Frozen Treats: Make homemade popsicles or sorbets with fruits like strawberries and mangoes.
Conclusion
While oranges are a known source of vitamin C, the Kakadu plum is the richest, followed by the acerola cherry and camu camu. Including these superfoods, alongside more common fruits like guava and strawberries, is an excellent way to increase vitamin C intake. Obtaining vitamin C from whole fruits provides additional nutrients and benefits compared to synthetic supplements, highlighting the value of a balanced, fruit-rich diet for overall health. Diverse fruit choices help ensure you get the necessary antioxidant and immune support daily.
