What does vitamin c do for children?
Vitamin C helps make collagen, supports wound healing and immune function, acts as an antioxidant, and improves absorption of iron from plant foods. Fruits and vegetables are the main sources.
Daily vitamin c needs by age
These are US Recommended Dietary Allowances for generally healthy children. Individual needs can differ because of health conditions, medicines, absorption, diet pattern, or professional treatment.
| Age | Male | Female |
|---|---|---|
| 1 to 3 years | 15 mg | 15 mg |
| 4 to 8 years | 25 mg | 25 mg |
| 9 to 13 years | 45 mg | 45 mg |
| 14 to 18 years | 75 mg | 65 mg |
What vitamin C does in the body
Vitamin C is required to make collagen, a structural protein used in skin, blood vessels, cartilage, bones, and connective tissue. It also participates in the production of certain neurotransmitters and carnitine, supports immune function, and works as an antioxidant that helps protect cells from oxidative damage.
Vitamin C also improves absorption of nonheme iron, the form found in plant foods. This makes vitamin C-rich produce particularly useful in meals based on beans, lentils, tofu, vegetables, and fortified grains.
Fresh, frozen, raw, and cooked
Peppers, citrus fruit, kiwifruit, strawberries, broccoli, Brussels sprouts, tomatoes, and potatoes can all contribute vitamin C. Frozen produce can be a practical option and is still nutritious. Juice contains vitamin C but whole fruit usually brings fiber and a more filling eating experience.
Vitamin C is water soluble and sensitive to prolonged heat. Cooking can reduce the amount in food, particularly when vegetables are boiled and the cooking water is discarded. This does not mean vegetables must always be raw. A mix of raw and gently cooked produce across the week is a practical approach.
Vitamin C-rich foods for children
Red and green peppers
Among the strongest common sources and useful raw or cooked.
Oranges and citrus
Provide vitamin C in fruit segments, salads, or alongside meals.
Kiwifruit
A compact fruit source with a bright, tart flavor.
Strawberries
Easy to combine with yogurt, oats, or snacks.
Broccoli
Contributes vitamin C along with fiber and other micronutrients.
Tomatoes
Useful fresh, roasted, or in sauces served with iron-containing foods.
A simple food-first pattern
Offer produce in forms the child already recognizes, then vary it gradually. Berries with breakfast, pepper strips with lunch, tomatoes in pasta sauce, or broccoli at dinner all count. Pairing one of these foods with lentils, beans, tofu, or iron-fortified cereal can support nonheme iron absorption.
Vitamin C deficiency is uncommon when diets contain some fruits and vegetables, but very restrictive eating can change the picture. High-dose supplements can cause gastrointestinal symptoms and are not a cure for colds or a replacement for a varied diet.
Common questions about vitamin c
How much vitamin C does a child need?
The US RDA is 15 mg for ages 1 to 3, 25 mg for ages 4 to 8, and 45 mg for ages 9 to 13. Teen recommendations are 75 mg for males and 65 mg for females.
Does cooking destroy all vitamin C?
No. Heat and water can reduce vitamin C, but cooked foods still contribute. Mixing raw and cooked produce is a practical way to preserve variety.
How does vitamin C help with iron?
Vitamin C improves absorption of nonheme iron from plant foods. Pairing a vitamin C food with beans, lentils, tofu, or fortified grains can be useful.
