30 Vitamin C Foods: Complete List & Amounts

By Dr. Dave Patel · Published March 4, 2026 · 9 min read

Vitamin C foods are your most reliable route to meeting daily ascorbic acid needs — and most people are surprised to learn that oranges are far from the top of the list. A yellow bell pepper sitting in your refrigerator contains nearly twice as much vitamin C per serving. This guide ranks 30 of the best sources with exact milligram amounts per typical serving, sourced from the USDA and NIH, so you know precisely where your vitamin C is coming from.

The Daily Value (DV) for vitamin C is 90 mg for adults. Almost any food on this list can put a meaningful dent in that target — some exceed it in a single half-cup serving.

What Does Vitamin C Do — and How Much Do You Need?

Vitamin C (ascorbic acid) is a water-soluble vitamin and one of the body's most important antioxidants. It performs four primary roles:

• Immune support — stimulates production and function of white blood cells, helping the body defend against infection
• Collagen synthesis — essential for skin integrity, cartilage health, and wound healing
• Iron absorption — enhances absorption of non-heme (plant-based) iron by up to threefold when consumed together
• Antioxidant protection — neutralizes free radicals that damage cells and accelerate aging

According to the NIH Office of Dietary Supplements, the Recommended Dietary Allowance (RDA) varies by group:

The tolerable upper intake level is 2,000 mg/day. Reaching that from food alone is virtually impossible, so toxicity from whole foods is not a realistic concern.

The 30 Best Vitamin C Foods Ranked

The table below ranks all 30 foods by vitamin C content per typical serving. Values are from USDA FoodData Central. Exotic superfoods (ranks 1–3) use a 100g reference since they are rarely eaten in larger quantities.

Exotic Superfoods: Nature's Richest Vitamin C Sources

The top three entries aren't found at a typical grocery store, but they're worth knowing about — and increasingly available as powders and supplements.

Kakadu plum (Terminalia ferdinandiana) is an Australian bush fruit containing roughly 100 times more vitamin C than an orange by weight. Indigenous Australians have used it medicinally for centuries, and freeze-dried powder is now available online and in specialty health stores.

Camu camu is a berry native to the Amazon rainforest. A 2021 study published in Nutrients (PMC) found it contains significant anti-inflammatory compounds alongside its exceptional vitamin C content of ~1,882 mg per 100g.

Acerola cherry (Malpighia emarginata) delivers ~825 mg per ½ cup — roughly 10 times more than an equivalent serving of orange juice. It is widely available as a supplement and found fresh or frozen in some specialty stores.

Best Fruits for Vitamin C

Among everyday fruits, guava (rank 5) is the standout. A single medium guava contains 125 mg of vitamin C — exceeding the full RDA for most adults in one piece. It is one of the most underrated fruits for vitamin C density, yet often overlooked in favor of citrus.

Yellow bell peppers (botanically a fruit) are the highest-ranked item available at any grocery store: half a cup raw delivers 137 mg, more than a full glass of orange juice. Red bell pepper (95 mg) and green bell pepper (60 mg) follow.

Other fruit highlights:

• Kiwifruit — 64 mg per medium fruit; excellent vitamin C-to-calorie ratio at just ~42 calories per kiwi
• Papaya — 87 mg per cup; also supplies vitamin A and digestive enzymes (papain)
• Strawberries — 49 mg per ½ cup; also rich in folate and anthocyanins
• Lychee — 68 mg per ½ cup; a tropical option often overlooked at the grocery store
• Citrus fruits — oranges (70 mg), grapefruit (44 mg), lemons (31 mg), limes (20 mg), and tangerines (26 mg) are all dependable everyday sources

Eating two to three servings of vitamin C-rich fruit daily covers the RDA with ease. Many of these fruits are also excellent fiber sources — see our guide to high-fiber foods for options that deliver both benefits.

Best Vegetables for Vitamin C

Vegetables are seriously underestimated as vitamin C sources. Several rival or exceed citrus fruits per serving.

Bell peppers dominate the vegetable category. Eaten raw, half a cup of yellow pepper delivers 137 mg, red pepper 95 mg, and green pepper 60 mg. Cooking reduces these numbers considerably (see the next section), so eating peppers raw as snacks or in salads maximizes your intake.

Kale is the leafy green standout: 80 mg per cup raw — more than a medium orange. Its vitamin C content also makes it an ideal companion for iron-rich plant foods like lentils and tofu, since vitamin C enhances non-heme iron absorption by up to threefold. This makes kale especially valuable for those following plant-based diets.

Other key vegetable sources:

• Broccoli — 51 mg per ½ cup cooked; also provides fiber and glucosinolates linked to cancer protection
• Brussels sprouts — 48 mg per ½ cup cooked; improve significantly when roasted rather than boiled
• Cauliflower — 26 mg per ½ cup raw; retains more vitamin C when eaten raw or microwaved
• Red cabbage — 20 mg per ½ cup raw; one of the most affordable high-vitamin C vegetables
• Spinach — only 9 mg per ½ cup cooked, but a nutritional powerhouse for iron, magnesium, and folate

Including a range of colorful vegetables is one of the cornerstones of a balanced diet — vitamin C is just one reason to prioritize variety.

How Cooking Affects Vitamin C Content

Heat, water, and oxygen all degrade ascorbic acid. The extent of loss depends heavily on the cooking method.

Cutting and storing produce also matters. Vitamin C oxidizes when exposed to air, so pre-cut vegetables lose vitamin C faster than whole ones. Cut produce just before eating when possible, and store whole fruits and vegetables in the fridge to slow oxidation.

Frequently Asked Questions

What food has the most vitamin C?

Among exotic superfoods, Kakadu plum leads with ~2,907 mg per 100g — about 100 times more than an orange by weight. For everyday grocery store picks, yellow bell pepper (137 mg per ½ cup) and guava (125 mg per medium fruit) are the highest. The orange, widely regarded as the vitamin C benchmark, contains a solid 70 mg per fruit but ranks 10th on this list.

How much vitamin C do you need per day?

The NIH recommends 90 mg/day for adult men and 75 mg/day for adult women. Pregnant women need 85 mg; breastfeeding women need 120 mg. Smokers should add 35 mg on top of the standard RDA because smoking increases oxidative stress and depletes ascorbic acid faster.

Do oranges have the most vitamin C of any fruit?

No — this is one of nutrition's most persistent myths. Oranges are an excellent, accessible source (70 mg per fruit) but are outperformed by yellow bell pepper, guava, blackcurrants, red bell pepper, papaya, kale, and kiwifruit in comparable serving sizes. The orange's reputation likely comes from its ubiquity and historical role in preventing scurvy during long sea voyages.

Does cooking destroy vitamin C?

Yes, but the extent varies significantly by method. Boiling reduces content by up to 50%; microwaving and steaming preserve 70–80%. Eating vegetables raw or lightly cooked is the best strategy for maximizing intake. For vegetables like tomatoes and potatoes that are primarily eaten cooked, their vitamin C contribution is still meaningful even after some heat-related loss.

Can you get enough vitamin C from food alone?

Absolutely. Meeting the 75–90 mg RDA is straightforward with a varied diet that includes a couple of servings of fruits and vegetables daily. A single serving of red bell pepper (95 mg) already exceeds the RDA on its own. Research consistently finds that food sources of vitamin C are as bioavailable as supplements for healthy adults.
