The Absolute Vitamin C Powerhouses
When discussing which plants have the most vitamin C, it is important to look beyond common grocery store staples. Several exotic and lesser-known fruits and vegetables outshine even the most famous citrus fruits by a significant margin. These nutritional titans are worth seeking out for a powerful vitamin boost.
Kakadu Plum: The World's Richest Source
At the very top of the list is the Kakadu plum, an indigenous superfood from Northern Australia. This small, green fruit contains the highest recorded natural vitamin C content of any food worldwide, with some reports suggesting up to 5,300 mg per 100g, although more commonly cited figures are around 2,907 mg. This is an extraordinary concentration, making it a highly sought-after ingredient in natural health products and supplements. The Kakadu plum is also rich in potassium, vitamin E, and antioxidants.
Acerola Cherry: A Tropical Heavyweight
Another undisputed leader in the vitamin C race is the acerola cherry, a tart, cherry-like fruit that grows in South America. Just half a cup (49g) of red acerola cherries can provide an astounding 1,650 mg of vitamin C, or 1,864% of the Daily Value per 100g, showcasing its incredible potency. Beyond its high vitamin C content, acerola cherries are loaded with beneficial polyphenols that help protect the body from oxidative stress and reduce inflammation.
Camu Camu: A South American Superfruit
Hailing from the Amazon rainforest, the camu camu berry is another formidable source of vitamin C. This small, sour berry is typically not eaten fresh but is processed into powder or capsules to preserve its nutrients. Camu camu contains up to 2,000 mg of vitamin C per 100g, making it a potent antioxidant source that is excellent for immune support and overall vitality.
Rose Hips: A Tangy Source from the Rose Plant
The rose hip is the small, sweet, and tangy fruit of the rose plant. This tiny fruit is also a fantastic source of vitamin C, with 100g providing 426 mg, or 473% of the Daily Value. Rose hips can be used to make teas, jams, and syrups, offering a delightful way to increase your intake.
Everyday Vegetables with Surprising Vitamin C Content
While exotic fruits may steal the spotlight, many familiar vegetables offer surprisingly high amounts of vitamin C and are more accessible for daily consumption.
- Yellow Bell Peppers: As bell peppers mature, their vitamin C content increases. One large yellow bell pepper provides 342 mg, or 380% of the Daily Value, which is more than double the amount in a green pepper.
- Broccoli and Brussels Sprouts: These cruciferous vegetables are well-known for their health benefits, and vitamin C is a major contributor. A half-cup of cooked broccoli provides 51 mg, while a half-cup of cooked Brussels sprouts offers 48 mg. Eating them raw or lightly steamed helps preserve more of the vitamin.
- Kale and Leafy Greens: Raw kale is a great source, providing 93 mg of vitamin C per 100g. Other dark leafy greens like mustard spinach (195 mg per raw cup) are also excellent sources.
The Best Fruits Beyond Citrus
For those looking to diversify their fruit intake, there are many delicious options that provide a hefty dose of vitamin C, often surpassing the amounts found in oranges.
- Guava: A single guava contains 125 mg of vitamin C, more than a medium orange. It is also a good source of fiber and the antioxidant lycopene.
- Kiwifruit: A single medium kiwi packs 64 mg of vitamin C, making it a reliable daily source. Kiwis are also rich in flavonoids and other antioxidants that support the immune system.
- Strawberries and Black Currants: These berries are packed with flavor and nutrition. One cup of sliced raw strawberries provides 97 mg of vitamin C, and a half-cup of black currants contains 102 mg.

How Cooking Affects Vitamin C Levels
Vitamin C is a water-soluble and heat-sensitive vitamin, meaning it can be easily degraded or lost during the cooking process. For example, boiling can reduce the vitamin C content of some vegetables by 20-43% or more. Here are some strategies for retaining the vitamin C in your food:
- Consume Raw: The best way to preserve vitamin C is to eat fruits and vegetables raw. Add bell peppers, kale, and strawberries to salads.
- Steam Instead of Boil: If you must cook, steaming is a gentler method that exposes the food to less water and heat, retaining more nutrients. Cooking greens like kale and spinach for shorter periods and at lower temperatures is a good practice.
- Quick Stir-Fries: A quick stir-fry can help minimize nutrient loss compared to prolonged boiling.
- Minimize Water Exposure: Don't soak produce for long periods before cooking.
Incorporating High-Vitamin C Plants into Your Diet
Making these vitamin C-rich plants a regular part of your diet is easy and delicious. Here are some simple ways to incorporate them into your daily meals:
- Smoothie Blends: Add acerola cherry or camu camu powder to your morning smoothie along with strawberries or kiwi for a massive vitamin C hit.
- Colorful Salads: Create vibrant salads with chopped yellow bell peppers, kale, spinach, and topped with fresh strawberries.
- Nutrient-Dense Sides: Serve lightly steamed broccoli or Brussels sprouts as a side dish with your meals.
- Herbal Teas and Infusions: Use dried rose hips for a tart, vitamin-rich herbal tea. You can also infuse water with sliced lemons and other fruits.
- Savory Dishes: Toss chopped yellow bell peppers into stir-fries, omelets, or pasta sauces. Guava can be used in savory glazes for meats or salads as well.
Conclusion: Maximizing Your Vitamin C Intake
While the orange is a household name for vitamin C, it is not the most potent source. To truly maximize your intake, consider exploring superfruits like the Kakadu plum, acerola cherry, and camu camu. Additionally, incorporating everyday vegetables like yellow bell peppers, broccoli, and kale, as well as fruits like guava and strawberries, can significantly boost your consumption. By prioritizing raw consumption and gentle cooking methods, you can ensure your body reaps the full range of benefits from these powerful plant sources, including enhanced immune function and antioxidant protection.
