Key takeaways:
Bell peppers, guava, and Brussels sprouts are among the foods highest in vitamin C.
Vitamin C strengthens your immune system, works as an antioxidant to prevent chronic health conditions, and helps your body absorb iron.
Certain medications can interfere with your body's ability to absorb vitamin C. Also, foods can lose some of their vitamin C when they’re exposed to high amounts of heat, light, air, or processing.
You’ve probably heard that vitamin C is good for your immune system. And, like many people, you may turn to a tall glass of orange juice when you want a dose of it.
But oranges are far from the only food serving up a hefty dose of vitamin C. Here are 14 of the top foods high in vitamin C.
Vitamin C: 171 mg (189% Daily Value, or DV) per 8 oz serving
Yes, tomato juice is a beverage, not a food. But its extremely high vitamin C content earns it the top spot on this list.
Tomato juice is also a great source of potassium. And tomatoes are full of lycopene, an antioxidant that can help protect against conditions like:
Prostate cancer
Heart disease
Type 2 diabetes
Stroke
Why do you need vitamin C? When you think of vitamin C, you may think of immune health. But vitamin C plays many more crucial roles throughout the body.
Does vitamin C help with colds? It’s common for people to take vitamin C to prevent and treat cold symptoms. But while vitamin C may help with colds, the effects are probably too small to notice.
Which foods are best for your immune system? Here’s a list of the foods, supplements, and vitamins that can help strengthen your immune system.
Not a fan of tomato juice? You can eat tomatoes instead. One medium tomato has 19% DV of vitamin C. And a cup of cherry tomatoes has 23%.
Vitamin C: 152 mg (169% DV) in one medium pepper
Red bell peppers contain the most vitamin C of all peppers. In a close second place are orange bell peppers (146 mg).
Bell peppers can be good to eat when you have a cold, since their antioxidants help with inflammation. Also, their high water content can help thin mucus and soothe a sore throat.
Vitamin C: 125 mg (140% DV) per fruit
Not only is guava full of vitamin C — it also contains protein (4 g per cup). This is unusual, since most fruits contain 1 g to 2 g of protein (or less) per serving.
Vitamin C: 88 mg (118% DV) per cup
This tropical fruit contains a digestive enzyme called papain, which may support healthy digestion and reduce symptoms like bloating, constipation, and gas.
Vitamin C: 98 mg (108% DV) per cup (sliced)
Strawberries are high in fiber but low in sugar. And many people don’t realize that strawberries have more vitamin C than oranges — by a lot. They’re also high in iron. These are just some of the reasons strawberries are one of the most nutritious fruits you can eat.
Vitamin C: 81 mg (90% DV) per cup (raw, chopped)
One cup of broccoli florets provides nearly 100% of your recommended daily vitamin C needs. As a cruciferous vegetable, broccoli has plenty of other health benefits, too, including the potential to reduce the risk of certain types of cancer.
Vitamin C: 79 mg (88% DV) per cup (chunks)
Pineapple contains a natural digestive enzyme called bromelain, which helps you digest protein. The bromelain in pineapple also gives it anti-inflammatory properties and benefits for your immune system.
Vitamin C: 75 mg (83% DV) per cup (raw)
Like broccoli, Brussels sprouts are a cruciferous vegetable high in vitamin C. They also contain folate (13% DV), which supports heart health and helps reduce the risk of birth defects. Not getting enough folate can lead to anemia, which is when the body doesn’t have enough red blood cells.
Vitamin C: 70 mg (77% DV) per medium orange
Oranges are famous for being a source of vitamin C. They’re also lower in naturally occurring sugar than many other fruits: about 12 g of sugar compared to 23 g in a cup of fresh mango.
And oranges have a low glycemic index (GI). That means that eating oranges causes a slower and less dramatic rise in blood sugar levels than eating fruits with a higher GI score. This can be especially helpful for people with prediabetes or diabetes — or anyone watching their blood sugar.
Vitamin C: 64 mg (71% DV) per fruit
In addition to its vitamin C, fiber, and antioxidants, this tropical fruit contains serotonin, which may promote healthy sleep. One small study reported that people who ate 2 kiwifruit before bedtime had significantly improved sleep quality and duration.
Vitamin C: 60mg (67% DV) per cup (pieces)
Mangos are higher in fruit sugar than some other fruits. But they also contain about 3 g of fiber per cup. Fiber helps slow down the absorption of sugar in the gut, which prevents blood sugar spikes. But note that dried mango often contains added sugar, so read the label to be sure.
Vitamin C: 59 mg (65% DV) in 1 cup (cubed)
Cantaloupe gets its orange color from beta carotene, an antioxidant that can be converted into vitamin A in your body. Both beta carotene and vitamin A are essential for eye health.
Vitamin C: 44 mg (59% DV) per medium fruit
Eating grapefruit can contribute to your daily hydration since it’s made up of 91% water. Just keep in mind that grapefruit contains compounds that interact with many types of medications, such as:
Statins
Some steroids
Certain blood pressure drugs
So if you take these medications, check with a healthcare professional before adding grapefruit to your diet.
Vitamin C: 51 mg (56% DV) per cup (chopped)
Red cabbage (sometimes called purple cabbage) provides vitamin K, which is essential for blood clotting. Red cabbage is also full of inflammation-busting antioxidants, including anthocyanins.
Vitamin C plays many essential roles in your body, including:
Supporting a strong immune system
Helping your body better absorb iron
Acting as an antioxidant to protect your body’s cells from damage that can otherwise increase your risk for conditions like cancer and heart disease
Helping produce collagen, essential for healthy skin and wound healing
Reducing inflammation
The table below shows the recommended dietary allowance (RDA) per day for vitamin C, according to the National Institutes of Health (NIH).
Age | Male | Female |
0-6 months | 40 mg* | 40 mg* |
7-12 months | 50 mg* | 50 mg* |
1-3 years | 15 mg | 15 mg |
4-8 years | 25 mg | 25 mg |
9-13 years | 45 mg | 45 mg |
14-18 years | 75 mg | 65 mg |
19+ years | 90 mg | 75 mg |
*For children under 1 year old, there’s no established RDA. The numbers above reflect the established Adequate Intakes (AI).
Note that some people may need more vitamin C, including people who:
Are pregnant or breastfeeding (80 mg to 120 mg per day)
Smoke cigarettes
Have a medical condition that impacts the small intestine, such as inflammatory bowel disease
Most people get enough vitamin C from their diets and don’t need supplements. And the best way to get vitamin C is through the foods you eat. That’s because foods that deliver vitamin C also provide other nutrients that benefit your health.
You can try:
Snacking on bell peppers with hummus
Mixing sliced oranges, strawberries, or kiwi into yogurt
Adding tomato sauce to pasta
Blending a smoothie using frozen pineapple, mango, or other fruits and vegetables rich in vitamin C.
There are some things that can degrade or destroy vitamin C in food, including:
Exposure to heat, like from high-temperature cooking
Prolonged storage
Excessive exposure to light
Exposure to air and oxygen
Processing, such as drying or salting
To help preserve the amount of vitamin C in your food, try to do the following:
Avoid cooking vitamin C foods at high temperatures, such as boiling or roasting. Microwaving or steaming will preserve more vitamin C compared to other cooking methods.
Lean on fresh or frozen fruit (and vegetables) over dried fruit.
Store cut or peeled fruit in an airtight bag or container, or wrap tightly with plastic wrap.
Note that some drugs can interfere with vitamin C absorption, or prevent vitamin C from working as well as it should in your body. Some of these medications include:
Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen
Tetracycline antibiotics
Proton pump inhibitors (PPIs)
The established upper limit for vitamin C for adults is 2,000 mg per day. This includes vitamin C from your diet and from supplements.
Getting more vitamin C than this can cause diarrhea, stomach cramping, and nausea. It can also cause iron overload in people with high iron stores, since vitamin C helps you absorb iron.
Too much vitamin C can also increase the amount of oxalate in your urine. This can increase your risk of developing calcium oxalate kidney stones.
Some research suggests that liposomal vitamin C may be the best form of the supplement to take. Liposomal supplements are encapsulated in tiny fat particles, which may make them easier for your body to absorb. These supplements may also come with fewer side effects.
Vitamin C does a lot for your body. It promotes a strong immune system, works as a powerful antioxidant, and supports skin health. Fruits and vegetables are the food groups highest in vitamin C, with bell peppers, guava, papaya, and strawberries leading the pack.
