What is vitamin C?

What is vitamin C?

Vitamin C, also known as ascorbic acid, is an essential nutrient. The word ‘essential’ here means that our body cannot produce it on its own and relies on external sources like food and supplements to fulfill its requirements.

This water-soluble nutrient plays a critical role in multiple bodily functions, including growth, development, and overall maintenance. It’s a potent antioxidant that helps safeguard our cells from damaging free radicals.

Additionally, Vitamin C aids in the production of collagen, a protein that provides structure to your skin, hair, nails, and bones.

Health benefits of vitamin C

The benefits of Vitamin C are numerous and range across various aspects of health. Here are a few key ones:

  • Immune Function: Vitamin C boosts our immune system by stimulating the production of white blood cells that fight off infections.
  • Collagen Production: It plays a vital role in collagen synthesis, which helps maintain skin's youthful appearance, healthy joints, and strong bone structure.
  • Antioxidant Activity: As a strong antioxidant, it protects our body cells from harmful free radicals that may cause chronic diseases.
  • Iron Absorption: Vitamin C also helps improve iron absorption from the food we consume. Improved iron absorption aids in preventing iron deficiency anemia.

Foods high in vitamin C

To meet our body's daily need for Vitamin C, incorporating certain foods in our diet can be helpful. The list includes:

  • Citrus fruits like oranges, lemons, grapefruits
  • Berries such as strawberries and raspberries
  • Green vegetables like spinach and broccoli
  • Bell peppers
  • Tomatoes
  • Fortified products like cereals

Symptoms of vitamin C deficiency

Deficiency of this crucial vitamin can lead to several health problems. Some common symptoms include:

  • Feeling tired or drained out more than usual
  • Getting frequent infections due to reduced immunity
  • Wounds take longer to heal as Vitamin C is essential for collagen production
  • Scurvy, an extreme Vitamin C deficiency condition characterized by swollen gums, anemia, and easy bruising

Who is at risk for vitamin C deficiency?

While everyone needs Vitamin C, some groups of people are more susceptible to deficiency. These include:

  • Smokers: Because smoking increases the amount of Vitamin C that the body needs to repair damage caused by free radicals.
  • Individuals with Limited Access to Fresh Produce: As fruits and vegetables are the main sources of Vitamin C.
  • People with Certain Medical Conditions: Such as certain types of cancer and kidney diseases that impair the body's ability to absorb or retain Vitamin C.

How much vitamin C do you need?

The recommended daily intake of Vitamin C varies depending on factors such as age, sex, and overall health. The Recommended Dietary Allowance (RDA) for Vitamin C established by the Food and Nutrition Board of the National Academies of Sciences, Engineering, and Medicine is as follows:

  • Adult men: 90 milligrams per day
  • Adult women: 75 milligrams per day
  • Pregnant individuals: 85 milligrams per day
  • Breastfeeding individuals: 120 milligrams per day

Can you overdose on vitamin C?

While Vitamin C is essential for good health, it is possible to consume too much of it. Excessive intake of Vitamin C, typically through supplementation, can lead to several potential adverse effects:

  • Gastrointestinal Distress: Consuming large doses of Vitamin C, especially in the form of supplements, may cause gastrointestinal discomfort such as diarrhea, nausea, and abdominal cramps. This occurs because Vitamin C is water-soluble, and excess amounts are excreted through the urine, drawing water into the intestines and potentially leading to loose stools.
  • Kidney Stones: High doses of Vitamin C can increase the excretion of oxalate in the urine, which may contribute to the formation of kidney stones in susceptible individuals. This risk is higher in individuals with a history of kidney stones or those predisposed to oxalate accumulation.
  • Iron Overload: Vitamin C enhances the absorption of non-heme iron (the type of iron found in plant-based foods and iron supplements). While this can be beneficial for individuals at risk of iron deficiency, excessive intake of Vitamin C may lead to iron overload in certain individuals, particularly those with hereditary hemochromatosis or other iron storage disorders.
  • Potential Interactions with Medications: High doses of Vitamin C may interact with certain medications, including blood thinners such as warfarin, increasing the risk of bleeding. Individuals taking medications should consult their healthcare provider before starting Vitamin C supplementation.
  • Increased Oxidative Stress: In some cases, high doses of Vitamin C may paradoxically act as a pro-oxidant rather than an antioxidant, especially in individuals with pre-existing conditions associated with oxidative stress, such as diabetes or cardiovascular disease.

The role of vitamin C supplements

The role of vitamin C supplements

While getting vitamin C from a well-balanced diet is ideal, some individuals may benefit from supplements— especially those with dietary restrictions or who are unable to eat a variety of fruits and vegetables. Additionally, those with certain diseases may have increased needs for vitamin C.

How does vitamin C interact with other nutrients?

Vitamin C assists in metabolizing other nutrients. It enhances iron absorption and also helps regenerate vitamin E, another antioxidant, enhancing its effectiveness in the body. However, it's important to note that high doses of vitamin C can interfere with the absorption of certain medications.

Latest research findings on vitamin C

Recent research continues to highlight the importance of Vitamin C for our health. A study from the Journal of the American College of Cardiology found Vitamin C supplementation may decrease cardiovascular disease risk through improved endothelial function and reduced inflammation.  

Another study in the Journal of Clinical Virology indicates that Vitamin C could reduce the severity and duration of cold symptoms. Furthermore, research in the Journal of the American Medical Association suggests that elderly individuals could see a reduced risk of pneumonia with Vitamin C supplementation.

From boosting our immune system to promoting skin health and aiding iron absorption, the benefits of vitamin C are vast and varied. Incorporating a variety of fruits and vegetables into your diet can help ensure you get adequate amounts of this essential nutrient.

However, if you fall into one of the higher-risk groups or have specific dietary restrictions, supplementation may be necessary - always after consulting with a healthcare professional. Remember, while vitamin C has many health benefits, it should be part of a balanced diet and not a substitute for a healthy lifestyle.
