A data-driven ranking of vitamin C-rich foods you can find in US groceries, with practical ways to use them and tips to preserve vitamin C.
Red bell pepper tops the list with about 190 mg per cup, raw.
Kiwi, strawberries, and Brussels sprouts deliver high vitamin C with broad US availability.
Cooking and storage can reduce vitamin C; quick, gentle heat retains more.
Whole foods beat juices for satiety and overall nutrition despite similar vitamin C.
Rankings use a weighted score: vitamin C per typical serving (50%), accessibility in mainstream US groceries (20%), prep convenience and retention when cooked (15%), sugar density (10%), and cost (5%). Vitamin C amounts are drawn from common USDA references for typical household servings. Whole foods are prioritized over juices and supplements.
Vitamin C supports immune function, collagen synthesis, and antioxidant defenses. Knowing which everyday foods deliver the most per serving helps you meet the 75–90 mg daily target (smokers need +35 mg) with minimal effort.
Highest vitamin C density per common serving, widely available and inexpensive year-round, easy to eat raw (maximizes retention). Low sugar, high versatility. Scores top across content, accessibility, and convenience.
Great for
Excellent vitamin C per compact serving, highly accessible and portable. Minimal prep, low-to-moderate sugar, and consistent year-round supply give it a strong composite score.
Peppers and cruciferous vegetables dominate: they combine high vitamin C with broad US availability and low sugar.
Raw or lightly cooked preparations preserve more vitamin C; shorter cook times, lower water contact, and adding vegetables near the end help retention.
Citrus is reliable and accessible but not the absolute highest per serving; berries and kiwis often surpass oranges.
Frozen fruit and vegetables can match fresh in vitamin C, offering value and convenience when items are out of season.
Frequently Asked Questions
Adults typically need 75–90 mg per day; smokers should add about 35 mg due to higher oxidative stress. Needs may vary with health status.
Yes. Vitamin C is sensitive to heat and water. Use quick methods (stir-fry, steam, roast briefly), add produce near the end of cooking, and avoid prolonged boiling to retain more.
Juices can be high in vitamin C, but they deliver more sugar and less fiber than whole fruit. For daily intake, prioritize whole foods and use juice in small portions.
Often yes. Frozen produce is typically picked ripe and flash-frozen, maintaining vitamin C well. It’s a cost-effective, convenient option when fresh isn’t in season.
Most people can meet needs through food. Supplements may help if intake is consistently low or under medical guidance. Aim to cover your base with food first.
For the most vitamin C with minimal effort, rely on peppers, kiwis, berries, and cruciferous vegetables, with oranges as an accessible standby. Keep prep simple and cooking brief to protect vitamin C, and use frozen options when it saves time and money.
