What vitamin C should a 14-year-old take?

4 min read

According to the National Institutes of Health, boys aged 14–18 have a recommended daily intake of 75 mg of vitamin C, while girls have a recommended intake of 65 mg. Discover what vitamin C should a 14-year-old take and the best ways to ensure they meet their daily requirements through a balanced diet.

Quick Summary

A 14-year-old's daily vitamin C needs vary by sex, with whole foods being the ideal source. This guide details specific daily requirements, top food sources, and discusses the role of supplements.

Key Points

  • Recommended Daily Intake: A 14-year-old boy has a recommended daily intake of 75 mg of vitamin C, while a girl has a recommended intake of 65 mg.

  • Best Source is Food: Whole fruits and vegetables, like bell peppers, oranges, and broccoli, are excellent sources of vitamin C.

  • Supplements Fill Gaps: Supplements should primarily be considered if dietary intake is insufficient or during periods of illness or stress, and after consulting a health professional.

  • Consider Upper Limit: There is a Tolerable Upper Intake Level (UL) for vitamin C intake for a 14-year-old, and exceeding certain amounts could potentially cause stomach issues.

  • Cooking Matters: Overcooking can potentially reduce vitamin C content in food; opt for raw or lightly steamed vegetables to potentially maximize nutrient retention.

  • Immune and Skin Health: Vitamin C is considered vital for immune system function and skin health.

  • Boosts Iron Absorption: Pairing vitamin C-rich foods with iron sources may help increase iron absorption, potentially important for teen girls.

The Vital Role of Vitamin C in Adolescent Development

Adolescence is a period of rapid growth and change, and proper nutrition is crucial to support these developmental shifts. Vitamin C, or ascorbic acid, is a powerful antioxidant that plays a key role in numerous bodily functions. For a 14-year-old, this essential nutrient is central to building a strong immune system, ensuring the formation of healthy bones and connective tissues, and supporting skin health, which can be a significant concern during the teenage years. Unlike some other vitamins, the human body cannot produce vitamin C, so it must be consumed regularly through food or supplements. This article will detail the specific recommended intakes for 14-year-olds and outline the best, safest, and most effective ways to meet those needs.

Recommended Daily Intake for 14-Year-Olds

The amount of vitamin C a teenager needs is a general guideline to support health. The Recommended Dietary Allowance (RDA) is the average daily level of intake sufficient to meet the nutrient requirements of nearly all healthy individuals.

  • Teen Boys (14–18 years): A recommended daily intake of 75 mg.
  • Teen Girls (14–18 years): A recommended daily intake of 65 mg.

It is also important to note that teenagers who smoke generally require additional vitamin C daily to compensate for the lower absorption and increased metabolic turnover of vitamin C caused by smoking. Meeting this general recommended intake is considered important for promoting general health and preventing deficiency symptoms.

Meeting Vitamin C Needs Through Diet

For most 14-year-olds, the best and safest way to get enough vitamin C is through a varied diet rich in fruits and vegetables. Many common foods are excellent sources of this nutrient, making it easy to incorporate into daily meals and snacks.

Excellent Food Sources of Vitamin C

  • Citrus Fruits: Oranges, grapefruits, lemons, and their juices are classic sources. A medium orange contains vitamin C, contributing to a 14-year-old girl's daily needs.
  • Berries: Strawberries, blueberries, and raspberries are packed with vitamin C and make a delicious addition to smoothies, yogurt, or as a snack.
  • Kiwi: One medium kiwi provides a significant amount of vitamin C, making it a highly concentrated source.
  • Bell Peppers: Both red and green bell peppers are surprisingly high in vitamin C, with a half-cup serving of chopped red bell pepper offering a substantial amount.
  • Cruciferous Vegetables: Broccoli, cauliflower, and Brussels sprouts are great sources. Steaming these vegetables can help preserve the vitamin C content, as it is water-soluble and can be lost during boiling.
  • Other Sources: Other vitamin C-rich foods include tomatoes, cantaloupe, and baked potatoes.

Incorporating a mix of these foods throughout the day is a simple and effective strategy. A morning smoothie with berries, bell peppers on a sandwich for lunch, and a serving of broccoli with dinner can help cover a teenager's needs.

Supplements: When to Consider Them

While food should be the primary source, some teenagers may benefit from a supplement. This could be due to factors like dietary restrictions, a busy schedule leading to inconsistent meals, or a consistently low intake of fruits and vegetables. For teen athletes, increased physical activity can also be a factor in nutrient considerations, though a supplement should still be considered after optimizing dietary intake.

Choosing a Supplement and Form

If a supplement is being considered, consulting a healthcare provider or a registered dietitian is a prudent first step. They can provide guidance on whether a supplement is potentially needed. Supplements typically contain vitamin C in the form of ascorbic acid, which is highly bioavailable and easily absorbed by the body. Some multivitamins also contain vitamin C, offering a range of nutrients in one product.

Food vs. Supplements: A Comparison

Feature Food-based Vitamin C Supplement-based Vitamin C
Source Natural fruits and vegetables Man-made products (pills, gummies, powder)
Nutrient Synergy Comes with fiber, other vitamins, and antioxidants Contains isolated vitamin C, possibly other added ingredients
Risk of Excess Extremely low risk of consuming excessive amounts Risk of side effects if upper intake level is exceeded
Absorption Generally excellent and accompanied by other nutrients Bioavailability is comparable to food for ascorbic acid
Cost Typically more affordable as part of a regular grocery budget Can be an additional recurring expense
Best For Meeting daily requirements for healthy individuals Filling potential nutritional gaps or addressing a deficiency under supervision

Potential Considerations of High Intake

While vitamin C is water-soluble and any excess is typically excreted in the urine, consuming very high amounts can potentially lead to adverse side effects. For teenagers aged 14–18, there is a Tolerable Upper Intake Level (UL) to consider. Consistently exceeding certain levels can potentially cause gastrointestinal issues such as diarrhea, nausea, heartburn, and stomach cramps. There may also be a potential link between very high intakes and the formation of kidney stones in susceptible individuals. Therefore, it is important to consider these factors and consult a professional if considering high-dose supplements. Here is a link to more information on vitamin C.

Conclusion

For a 14-year-old, the best approach to meeting their vitamin C needs is typically through a balanced diet rich in a variety of fruits and vegetables. Boys generally have a recommended intake of 75 mg and girls 65 mg daily, targets that can often be reached by incorporating foods like citrus fruits, bell peppers, and strawberries into their meals and snacks. While supplements may be an option for those with dietary gaps, they are generally not necessary for most healthy teenagers and should be discussed with a healthcare provider. By focusing on whole foods, parents can help ensure their teenagers get the essential nutrients they need to support their growth, immunity, and overall well-being during this critical stage of life.
