10 Fruits Rich in Vitamin C and Their Impact on Your Health

Vitamin C, also known as ascorbic acid, is a water-soluble nutrient that is widely recognized for its role in strengthening immunity. However, its benefits extend far beyond that. Fortunately for fruit enthusiasts, many of the best vitamin C sources are among the most popular fruits. Keep reading to uncover how vitamin C contributes to overall health and which fruits are packed with this essential nutrient.

What Are the Health Benefits of Vitamin C?

Vitamin C is primarily recognized for its antioxidant properties, helping to boost the immune system by reducing inflammation and neutralizing free radicals. 'Free radicals are unstable molecules naturally produced by the body and environmental factors—such as pollution, cigarette smoke, pesticides, and UV rays,' explains Jessica G. Anderson, MS, RD, CSSD, LD, ACSM EP-C, Registered Dietitian Nutritionist at Top Nutrition Coaching. 'Vitamin C is also essential for the synthesis of collagen, L-carnitine (a substance crucial for metabolism), the production of certain neurotransmitters, protein metabolism, and the formation and repair of connective tissue, muscle, bone, and blood vessels,' Anderson continues.

These remarkable effects have led to vitamin C being linked to a lower risk of conditions such as cancer, autoimmune diseases, cataracts, age-related macular degeneration, rheumatoid arthritis, heart disease, neurodegenerative diseases (like Alzheimer’s and Parkinson’s), the common cold, and premature skin aging, as explained by Anderson.

How Much Vitamin C Should We Consume Daily?

So, how much vitamin C should we aim for each day to enjoy these significant health benefits? The National Institutes of Health (NIH) recommends the following daily intake amounts (RDAs) for adults over 19 years old:

• Men: 90 milligrams (mg) per day
• Women: 75 mg per day
• Pregnant Women: 85 mg per day
• Lactating Women: 120 mg per day

It’s not unusual to find high levels of vitamin C in supplements—sometimes exceeding 200 percent of the recommended daily amount in one serving. The Tolerable Upper Intake Level (UL) for vitamin C in adults is 2,000 mg. Consistently going over this amount can negatively affect our health. 'Vitamin C can become a ‘pro-oxidant,’ potentially contributing to more cellular damage and increasing the risk of the very health issues it’s meant to protect against (when taken in recommended amounts),' explains Anderson.

Signs of too much vitamin C include nausea, vomiting, diarrhea, and abdominal cramps. With this in mind, it’s best to prioritize whole food sources of this essential antioxidant before turning to supplements. However, do be mindful of the vitamin C content in any supplements you’re already taking.

10 Fruits Packed with Vitamin C

When it comes to whole food sources, many fruits are exceptionally high in this water-soluble vitamin. Here’s a list of the top 10 fruits that are loaded with vitamin C:

Oranges

It’s no surprise that oranges rank high on this list, as they’re commonly associated with vitamin C. One medium-sized orange contains about 70 mg of this vital nutrient. This amount is generally consistent across various types of oranges found at your local grocery store.

Guava

Though it may be a bit harder to find in stores, guava is an excellent source of immune-boosting vitamin C. A single cup of guava packs an impressive 376 mg of this vitamin! If guava isn’t available at your grocery store, guava juice can provide a similar boost (just check the nutrition facts to see the exact amount).

Kiwi

Kiwifruit, also known as kiwi, is not just tangy and refreshing—it’s packed with nutrients, including vitamin C. One medium kiwi contains a remarkable 64 mg of this essential vitamin.

Strawberries

Strawberry season is just around the corner. Even if local strawberries aren’t available, you can find them in most grocery stores year-round, either fresh or frozen (though they may not be as sweet). Half a cup of strawberries provides 49 mg of vitamin C.

Papaya

This tropical fruit can be a bit hard to find, but papaya is an outstanding source of vitamin C. One cup of chopped papaya contains 88 mg of the vitamin, and many 100 percent fruit juices containing papaya also offer high amounts of vitamin C.

Cantaloupe

Few things compare to the joy of cantaloupe slices during peak harvest season. This sweet and juicy melon isn't just a treat—it’s packed with essential nutrients like vitamin C. One cup provides 58 mg, helping you meet your daily intake goals.

Grapefruit

Although the bitter taste of grapefruit may not appeal to everyone, many people make it a morning ritual. Half of a medium grapefruit offers 39 mg of vitamin C, and ¾ cup of grapefruit juice delivers a noteworthy 70 mg.

Apples

Few fruits are as easy to find as the humble apple, making it a reliable choice when you need a quick vitamin C and fiber boost. No matter the variety, one medium apple contains a modest (but still valuable) eight mg of vitamin C.

Pineapple

Known for being one of the most affordable tropical fruits in the store, pineapple is packed with nutrients like fiber, vitamin B6, magnesium, iron, and calcium. It’s also an excellent source of vitamin C, providing 79 mg per cup.

Cherries

A favorite snack, cherries deliver a sweet burst to keep you satisfied between meals. As an added perk, they’re also loaded with nutrients, including vitamin C.

Other Foods Rich in Vitamin C

Other excellent fruit sources of vitamin C include lemons, limes, lychees, persimmons, and black currants. However, fruits aren’t the only group rich in this essential micronutrient. Bell peppers, broccoli, snow peas, kale, chili peppers, banana peppers, kohlrabi, parsley, Brussels sprouts, rosehips, and tomatoes (technically a fruit) are also fantastic sources of vitamin C.

Adding Vitamin C-Rich Foods Into Your Daily Routine

There are countless ways to incorporate these vitamin C-packed foods into your day. You can add fruit sources to smoothies, oatmeal, overnight oats, chia pudding, baked goods, homemade jams, pancakes, and salads. Veggies can be included in pastas, rice dishes, egg-based meals, casseroles, salads, slaws, soups, grain bowls, and more. By aiming for at least two to three servings of the top sources listed here, you’ll likely meet your daily vitamin C requirements without needing supplements.

The Bottom Line
