Kakadu Plum Packs Up to 5,000mg of Vitamin C per 100 Grams

Q: If oranges aren't the ultimate vitamin C source, what hidden supermarket vegetable actually packs triple the immune-boosting power?

The hidden supermarket “vegetable” is the bell pepper, especially red, yellow, or orange varieties. They generally deliver about 165 to 169 mg of vitamin C each, roughly triple the amount in a typical orange, which has about 53 to 70 mg. That makes bell peppers one of the strongest easy-to-find vitamin C sources in an ordinary grocery store. They are technically fruits, but they are usually bought and eaten as vegetables. Nutrition data cited in the roundup and supporting sources show red bell peppers at about 168.9 mg of vitamin C, orange peppers at 168.8 mg, and yellow peppers at 165.4 mg. Even green bell peppers are high, at around 118 mg. The comparison matters because oranges have the strongest reputation, not the highest concentration. Most adults need about 75 to 90 mg of vitamin C a day, so one bell pepper can easily cover the daily requirement, while an orange often falls short of the full target. Experts also note that vitamin C supports immune function, collagen production, antioxidant defense, and iron absorption. Because the vitamin is heat-sensitive, eating bell peppers raw or only lightly cooked helps preserve more of it. So if the goal is a practical, supermarket-friendly vitamin C upgrade, bell peppers are the standout choice, with red peppers leading the pack.

Kakadu plum, a small fruit native to northern Australia, contains 1,000 to more than 5,000mg of vitamin C per 100 grams, making it the most concentrated natural source recorded.
That level is up to 100 times the vitamin C in an orange, which provides about 53mg, and far above other common fruits highlighted in the ranking.
Among those alternatives, Guava delivers roughly 228mg per 100 grams, Blackcurrants 181mg, kiwi about 93mg per fruit, papaya 88mg per cup and strawberries 89mg per cup.
The comparison underscores how vitamin C content varies sharply across fruits, with familiar citrus no longer the benchmark for the highest natural concentration.
