The Richest Fruit Sources of Vitamin C
While citrus fruits are commonly associated with vitamin C, many other fruits offer even higher concentrations. Incorporating a variety of these fruits can significantly boost your daily intake.
Tropical Fruits
Tropical fruits are often vitamin C powerhouses. The Kakadu plum contains an exceptionally high amount, while more accessible options like acerola cherries deliver a staggering 1,650 mg per half-cup. Other tropical fruits rich in vitamin C include guava (up to 376 mg per cup), papaya (88 mg per cup), and kiwi (a single medium fruit provides over 100% of the recommended daily intake).
Berries and Melons
Berries and melons also contribute to vitamin C intake. A cup of sliced strawberries contains nearly 100 mg, exceeding the amount in a medium orange, while black currants provide 102 mg per half-cup serving. Cantaloupe is another source, offering about 65 mg per cup.
The Best Vegetable Sources of Vitamin C
Vegetables are crucial sources of vitamin C, with many containing high levels, often surpassing popular fruits.
Bell Peppers
Bell peppers are among the most concentrated and accessible vegetable sources of vitamin C. Their content increases with ripening, with yellow and red varieties being particularly high. A large yellow bell pepper can provide up to 342 mg, and a red one contains 213 mg.
Cruciferous Vegetables
Cruciferous vegetables are dietary staples that provide significant vitamin C. One cup of cooked broccoli contains 81.2 mg, a half-cup of Brussels sprouts offers 48 mg, and a cup of raw cauliflower has 51.6 mg.
Other Vitamin C-Rich Vegetables
Other vegetables contribute to vitamin C intake as well. A medium tomato provides about 17 mg, and this content is well-retained in sauces. A medium-baked potato with its skin also offers around 17 mg of vitamin C.
Considerations for Food Preparation
Vitamin C is sensitive to heat, light, and air. To maximize intake, consuming raw produce is often best. When cooking, opt for steaming or microwaving for short durations over boiling, as boiling can cause the nutrient to leach into the water. Proper storage in a cool, dark place and consuming fruits and vegetables soon after purchase also helps preserve vitamin C levels.

This table compares the vitamin C content of various popular foods per serving:
| Food Source (Raw) | Serving Size | Vitamin C (mg) | Daily Value (%) |
|---|---|---|---|
| Yellow Bell Pepper | 1 large (186g) | 342 | 380% |
| Acerola Cherries | 1/2 cup (49g) | 1650 | 916% |
| Guava | 1 cup (165g) | 376 | 417% |
| Kiwi | 1 medium (69g) | 64 | 71% |
| Orange | 1 medium (131g) | 70 | 78% |
| Strawberries | 1 cup, sliced (166g) | 97 | 108% |
| Broccoli | 1 cup, raw (91g) | 81.2 | 90% |
Conclusion: A Balanced Approach to Vitamin C
While citrus fruits are well-known, many fruits and vegetables provide even higher amounts of vitamin C. The most abundant sources include tropical fruits like acerola cherries and guava, alongside vegetables such as yellow bell peppers and broccoli. By including a wide variety of these foods in your daily diet, particularly consumed raw or lightly cooked, you can easily meet your recommended intake. A diet rich in diverse produce is the most effective strategy for maintaining optimal vitamin C levels and supporting overall health and immune function.

Get More Vitamin C in Your Diet
- Increase Variety: Explore diverse berries, peppers, and leafy greens to enhance your vitamin C intake beyond common sources.
- Embrace Raw Foods: Incorporate raw produce like berries, bell pepper strips, and kiwi into your meals and snacks to maximize vitamin C retention.
- Prioritize Light Cooking: Choose steaming, sautéing, or microwaving for vegetables to minimize nutrient loss during preparation.
- Enjoy Smoothies: Blend vitamin C-rich fruits and greens for a convenient way to consume these nutrients in their fresh state.
- Consume Promptly: Eat fresh produce soon after purchasing to benefit from the highest vitamin C content, as it decreases over time.
The Role of Vitamin C
Vitamin C, or ascorbic acid, is a water-soluble antioxidant that protects cells from free radical damage. It's essential for collagen synthesis, supporting skin, bones, cartilage, and wound healing. It also plays a key role in immune function and improves iron absorption from plant-based foods. Since the body doesn't store it, a consistent daily dietary intake is crucial.
