The Uncontested Champion: Kakadu Plum
When considering which food has the highest vitamin C, most people think of citrus fruits like oranges. However, the true champion is the Kakadu plum, a superfood native to Australia that boasts the highest known concentration of this essential nutrient. Containing between 2,300 and 3,150 mg of vitamin C per 100 grams, a single plum can provide over 480% of the daily recommended value. While it is not widely available fresh, it is often sold as a supplement in powder form.
Other Top-Ranking Superfruits
While the Kakadu plum is in a league of its own, other exotic fruits pack an impressive vitamin C punch. These options, while less common than an orange, are often found in health food stores or specialty markets and are excellent for boosting your intake.
- Acerola Cherries: These small, red cherries are another powerhouse source. Just half a cup (49g) provides 1,650 mg of vitamin C, which is over 900% of the Daily Value (DV). Acerola is also a rich source of antioxidants and beneficial polyphenols.
- Camu Camu: This Amazonian fruit, often sold as a powder, contains approximately 1,800 mg of vitamin C per 100g, earning its reputation as a potent superfood. Its tangy flavor makes it a perfect addition to smoothies and yogurt.
- Rose Hips: The fruit of the rose plant, rose hips are a fantastic source of vitamin C. Per 100g, they contain 426 mg, or 473% of the DV. They are often used to make teas, jellies, and jams.
- Guavas: This tropical fruit offers a significant dose of vitamin C. A single guava contains around 125 mg of the vitamin, providing 138% of the DV. Guavas are also rich in fiber and antioxidants like lycopene.
- Blackcurrants: Small but mighty, blackcurrants provide 102 mg of vitamin C per half-cup serving, exceeding the DV. These berries also contain anthocyanins, powerful antioxidants that contribute to their deep, dark color.
Accessible Everyday Sources
For most people, accessing exotic superfoods might not be practical. Fortunately, many common fruits and vegetables are excellent, readily available sources of vitamin C. Incorporating these into your daily meals is a simple way to maintain optimal levels.
- Bell Peppers: Red bell peppers are surprisingly high in vitamin C. A half-cup serving of raw red pepper contains 95 mg, which is more than the DV and significantly more than an orange. Yellow bell peppers are even more potent, with one large yellow pepper offering 342 mg.
- Kale and Broccoli: These cruciferous vegetables are nutrient-dense powerhouses. Raw kale provides 93 mg of vitamin C per 100g. Half a cup of cooked broccoli offers 51 mg, contributing over half of the DV.
- Strawberries: One cup of sliced strawberries contains 97 mg of vitamin C, surpassing the DV. These berries are also packed with fiber and other antioxidants.
- Brussels Sprouts: A half-cup of cooked Brussels sprouts provides 48 mg of vitamin C. Roasting them can bring out a delicious nutty flavor while preserving many of their nutrients.
- Kiwi: While not the highest source, one medium kiwi still provides a solid 64 mg of vitamin C, accounting for 71% of the DV. Kiwis are also a good source of fiber and potassium.
The Impact of Cooking and Storage
Vitamin C, also known as ascorbic acid, is a water-soluble and heat-sensitive vitamin. This means its content can be significantly reduced during cooking and storage. To maximize your intake, it's best to consume vitamin C-rich foods raw or lightly cooked.
- Avoid Boiling: Boiling vegetables can cause a significant loss of vitamin C, as the nutrient leaches into the water.
- Opt for Steaming or Microwaving: These cooking methods use less water and shorter cooking times, which helps to preserve more of the vitamin C.
- Store Properly: Keep fruits and vegetables in a cool, dark place or in the refrigerator to slow the degradation of nutrients.
Comparison Table: Vitamin C Content per Serving
To put these options in perspective, here is a comparison of the vitamin C content in various popular foods.
| Food (Serving) | Vitamin C (mg) | Daily Value (%) |
|---|---|---|
| Kakadu Plum (15g) | ~350–480 | ~484% |
| Acerola Cherries (½ cup) | 1650 | 916% |

Conclusion
While oranges may be the most famous vitamin C source, they are far from the richest. The title for the food with the absolute highest vitamin C concentration belongs to the exotic Kakadu plum. However, for everyday consumption, a wide variety of readily available and delicious fruits and vegetables offer substantial amounts of this vital nutrient. By incorporating foods like bell peppers, guavas, and broccoli into your diet, and paying attention to cooking methods, you can easily meet your daily vitamin C needs to support your immune system, skin health, and overall well-being. For more detailed information on nutrient content, consult reputable sources such as the National Institutes of Health.
