Surprising Vitamin C Superstars: Beyond the Citrus Family
Many people associate vitamin C exclusively with citrus fruits, but a wide variety of other options offer superior levels of this essential nutrient. Vitamin C, also known as ascorbic acid, is a powerful antioxidant that helps protect your cells from damage caused by free radicals. It is crucial for maintaining a healthy immune system, aiding collagen production for skin health, and improving iron absorption. Your body cannot produce vitamin C, so obtaining it through diet is vital. The Recommended Dietary Allowance (RDA) is 90 mg for adult men and 75 mg for adult women, but incorporating higher-potency foods can offer additional benefits.
The Unexpected Heavy-Hitters
Several fruits and vegetables stand out for their exceptional vitamin C content. Incorporating these into your diet can significantly boost your daily intake.
- Kakadu Plums: Hailing from Australia, these are the single richest-known food source of vitamin C. Just one small plum can contain as much as 480 mg of vitamin C, over 5 times the daily recommended value. While not widely available, they are a testament to how potent non-citrus sources can be.
- Acerola Cherries: These small, red cherries are another vitamin C powerhouse. A half-cup serving delivers an incredible 1,650 mg of vitamin C, providing more than 1,800% of the daily value.
- Guava: This tropical fruit offers 125 mg of vitamin C in a single fruit, more than a typical orange. Guavas also provide fiber and antioxidants, supporting heart and digestive health.
- Kiwis: One medium kiwi contains around 64 mg of vitamin C, making it a highly efficient source. Beyond its vitamin C content, kiwi fruit is also known for its fiber and potential anti-inflammatory properties.
- Strawberries: A cup of sliced strawberries provides 97 mg of vitamin C, surpassing a medium orange. They are also rich in antioxidants and manganese.
- Papaya: This sweet, orange fruit packs about 88 mg of vitamin C per cup. Papaya is also a great source of carotenoids and other antioxidants.
Vitamin C Beyond Fruits
It’s not just fruits that contain high levels of vitamin C. Some vegetables are excellent sources and can easily be integrated into meals.
- Bell Peppers: The vitamin C content in bell peppers increases as they ripen. A large yellow bell pepper can provide a whopping 342 mg of vitamin C, more than twice the amount in a green pepper. Red bell peppers are also an impressive source, with 191 mg per cup.
- Black Currants: These dark berries offer a tart flavor and a high concentration of vitamin C, with 102 mg in a half-cup serving.
- Broccoli: A half-cup of cooked broccoli provides about 51 mg of vitamin C, along with fiber and other antioxidants. Steaming helps retain more of the vitamin C compared to boiling.
- Brussels Sprouts: Another cruciferous vegetable, Brussels sprouts provide 48 mg of vitamin C per half-cup when cooked. They are also a good source of vitamins K and A.
- Cantaloupe: A single cup of cantaloupe delivers 17 mg of vitamin C, along with vitamin A and other nutrients.

Making the Most of Your Vitamin C Intake
To ensure you are getting the most out of your vitamin C sources, consider a few key things. Vitamin C is water-soluble and sensitive to heat, so eating raw fruits and vegetables is ideal for maximum nutritional benefit. If cooking, opt for methods like steaming that minimize nutrient loss. It is also important to consume vitamin C as part of a balanced diet that includes other antioxidants and nutrients, as these compounds often work synergistically in the body.
