Humans need Vitamin C to form blood vessels, cartilage, muscle and collagen. Vitamin C is also vital to our bodies’ healing processes and it’s an antioxidant that protects our cells from harm. Our bodies don’t naturally produce Vitamin C—also known as ascorbic acid—so we must get it from our diet.

Swipe through to learn which foods are high in Vitamin C.

The most well-known providers of Vitamin C are oranges. A medium orange provides 60 to 83 milligrams of vitamin C, which almost meets the recommended daily requirements of the nutrient— most people should aim to get 65 to 90 milligrams per day. Other citrus fruits such as grapefruit, lemons and limes also provide good amounts of Vitamin C.

Strawberries are another fruit that are good source of Vitamin C. Each berry provides about 7 milligrams of the nutrient, so a generous handful will get you close to your daily needs. The tasty red fruit also provides folate and potassium.

This one might surprise you, but peppers are an excellent source of Vitamin C. Both bell peppers and spicy peppers are full of the mineral. Red bells have more than green or yellow, but any pepper is a great source of ascorbic acid.

If your kids won’t eat oranges to get their Vitamin C, but they like vegetables, you can always offer Brussels sprouts as an alternative. A cup of the little green orbs provides about 75 milligrams of the nutrient.

Potatoes are a good source of Vitamin C. Ignore the carbs and focus on the 27 milligrams of ascorbic acid per serving that potatoes provide. Keep the peels on for full health benefits, which include Vitamin B6 and magnesium.

Broccoli is another green vegetable that packs a Vitamin C punch, with a half-cup of the green vegetable providing about 57 milligrams of ascorbic acid. Broccoli is also a good source of calcium and iron.

Guava is among the foods richest in Vitamin C, with one fruit providing a whopping 125.6 mg of the nutrient. This sweet, tropical fruit is also an excellent source of fiber, and contains Vitamin B6 and magnesium, too.
