Vitamin C may not directly protect you from catching germs, but it plays a critical role in supporting immune function, wound healing, collagen production, and overall health. It also acts as a powerful antioxidant, helping protect your cells from damage caused by free radicals.

Most adult women need at least 75 milligrams (mg) of vitamin C per day, while men require about 90 mg daily. Instead of turning to supplements, health experts typically recommend meeting your vitamin C needs through whole foods. That’s because foods rich in vitamin C also provide fiber, phytonutrients, minerals, and other vitamins that work together to support your health.

If you’re looking to boost your intake naturally, here are eight vitamin C–rich foods that can easily replace a pill or gummy.

1. Red Bell Pepper

Vitamin C: 118 mg (131% of the Daily Value)
Serving size: 1 cup, sliced

Citrus fruits usually get the credit for vitamin C, but red bell peppers actually contain more per serving than most oranges. In addition to vitamin C, they provide vitamin B6, potassium, and magnesium — nutrients that support heart health, brain function, and strong bones.

They’re easy to add to salads, stir-fries, omelets, or enjoyed raw with hummus for a crunchy snack.

2. Kiwi

Vitamin C: 105 mg (117% of the Daily Value)
Serving size: 1 cup

Just one cup of kiwi delivers more than your daily requirement for vitamin C. These small but mighty fruits are also rich in fiber and antioxidants.

For extra nutritional benefits, consider eating kiwi with the skin (after washing it well). The skin boosts fiber intake and adds even more antioxidant compounds.

3. Broccoli

Vitamin C: 102 mg (113% of the Daily Value)
Serving size: 1 cup, chopped

Broccoli is well known for its immune-supporting properties. Beyond vitamin C, it contains selenium, zinc, vitamin K, vitamin E, vitamin A, potassium, and phosphorus — all of which contribute to strong immunity, bone health, and proper cell function.

Lightly steaming broccoli helps preserve its nutrients while making it easier to digest.

4. Kale

Vitamin C: 93 mg (103% of the Daily Value)
Serving size: 100 grams (about 1.5 to 2 cups raw)

Kale has earned its reputation as a superfood — and for good reason. In addition to vitamin C, it provides more than 300% of the daily value for vitamin K, which is essential for blood clotting and bone strength.

It also contains antioxidants and fiber that support heart and digestive health. Add kale to smoothies, salads, soups, or sauté it as a nutrient-packed side dish.

5. Strawberries

Vitamin C: 89 mg (99% of the Daily Value)
Serving size: 1 cup, halved

A single cup of strawberries nearly covers your full daily vitamin C needs. These sweet berries are also rich in anthocyanins — antioxidant compounds linked to reduced inflammation and heart health benefits.

They’re delicious in yogurt, oatmeal, smoothies, or simply eaten fresh as a snack.

---

6. Grapefruit

Vitamin C: 85 mg (94% of the Daily Value)
Serving size: 1 cup

Though its slightly bitter flavor isn’t for everyone, grapefruit is a nutritional powerhouse. It contains vitamin C, fiber, vitamin A, and potassium, supporting gut health, eye function, heart health, and immunity.

Grapefruit can be enjoyed broiled with a small touch of sweetener, added to salads, mixed into breakfast bowls, or infused into water for a refreshing twist.

Note: Grapefruit may interact with certain medications, so check with your healthcare provider if you take prescriptions.

7. Oranges

Vitamin C: 83 mg (92% of the Daily Value)
Serving size: 1 cup

Oranges are the classic vitamin C source — and for good reason. They’re convenient, portable, and packed with additional nutrients such as B vitamins, vitamin E, fiber, calcium, and potassium.

Eating whole oranges (instead of just drinking juice) provides more fiber and helps regulate blood sugar levels.

---

8. Brussels Sprouts

Vitamin C: 75 mg (83% of the Daily Value)
Serving size: 1 cup, raw

Often featured in roasted vegetable dishes and winter salads, Brussels sprouts are loaded with nutrients. Along with vitamin C, they offer folate, manganese, potassium, magnesium, phosphorus, and fiber.

Roasting them with olive oil and garlic can enhance both flavor and nutrient absorption.

Who Might Benefit From a Vitamin C Supplement?

Most people can meet their vitamin C needs through a balanced diet rich in fruits and vegetables. However, supplementation may be appropriate in certain situations.

Individuals who may benefit from supplements include:

• People with very limited diets or poor appetites

• Those with digestive conditions that impair nutrient absorption

• Smokers (who require higher vitamin C intake)

• Pregnant or breastfeeding individuals

• People experiencing food insecurity

Registered dietitians recommend speaking with a healthcare provider before starting any supplement — including vitamin C — to ensure the dosage is appropriate and safe for your individual needs.

The Bottom Line

While vitamin C won’t act as a shield against germs, it remains a vital nutrient for immune defense, skin health, wound healing, and antioxidant protection. The best way to meet your daily requirement is by incorporating a variety of colorful fruits and vegetables into your meals.

By choosing whole foods over supplements whenever possible, you gain not just vitamin C — but a full spectrum of nutrients that work together to support long-term health.
