All That You Need To Know About Vitamin C – The Immunity-Boosting Nutrient

In the realm of health and well-being, few nutrients stand out as prominently as Vitamin C. This essential nutrient plays a crucial role in supporting our immune system, acting as a shield against various illnesses and infections. 

As we delve into the world of Vitamin C, let’s uncover its secrets and understand why it’s hailed as a cornerstone for robust immune health.

What is Vitamin C?

Vitamin C, scientifically known as ascorbic acid, is a water-soluble vitamin found in various fruits and vegetables. Its chemical properties make it a vital component for the proper functioning of our body. While commonly associated with oranges, Vitamin C is present in a wide array of natural sources.

The Role of Vitamin C 

Vitamin C plays an essential role in many body functions. From boosting your immunity to improving your skin, this nutrient can do wonders for you.

1. The Role of Vitamin C in Immune Health

Our immune system serves as the body’s defence mechanism against pathogens. Vitamin C plays a pivotal role in this system by supporting the production and function of white blood cells, the frontline soldiers in our immune response. Ensuring an adequate intake of Vitamin C is, therefore, essential to fortify our natural defences.

2. Stimulation of White Blood Cell Production

Vitamin C plays a pivotal role in supporting the production and function of white blood cells, particularly lymphocytes and phagocytes. These cells are fundamental components of the immune system, responsible for identifying and neutralising pathogens. Research highlights the essential role of Vitamin C in the differentiation and maturation of white blood cells, contributing to an effective immune response. 

Vitamin C enhances the function of immune cells by supporting their migration to sites of infection and improving their ability to engulf and destroy pathogens. Studies indicate that Vitamin C can shorten the duration of respiratory infections, further emphasising its positive impact on immune function. 

3. Antioxidant Properties

Beyond its role in immune function, Vitamin C boasts powerful antioxidant properties. Acting as a scavenger for free radicals, it helps protect our cells from oxidative stress. This supports overall health and contributes to the prevention of chronic diseases.

4. Benefits for Cold and Flu Prevention

Numerous studies have explored the connection between Vitamin C and the prevention of colds and flu. Regular and sufficient Vitamin C intake has been linked to a reduced risk of falling ill, making it a popular choice during flu seasons. Understanding the recommended daily intake becomes crucial for those looking to bolster their immune defences.

5. Wound Healing and Collagen Production

Another remarkable aspect of Vitamin C is its involvement in collagen synthesis. Collagen, a protein that provides structure to our skin, plays a key role in wound healing and tissue repair. Ensuring an ample supply of Vitamin C accelerates these processes, contributing to healthier skin and faster recovery.

Vitamin C Deficiency

Despite its importance, Vitamin C deficiency is not uncommon. Recognising the symptoms, such as fatigue, muscle weakness, and joint pain, is crucial for early intervention. Risk factors, including poor dietary choices and certain medical conditions, can contribute to low Vitamin C levels.

Best Ways to Consume Vitamin C

Dietary choices form the primary source of Vitamin C. Including citrus fruits, strawberries, broccoli, and bell peppers in your meals can significantly boost your intake. Supplements like Route2Health’s Vitamin C should be considered for those with specific needs or challenges in obtaining sufficient Vitamin C from food alone. However, it’s essential to strike a balance and avoid excessive doses.

Recommended Daily Intake

Guidelines for Vitamin C intake vary across different age groups. Infants, children, adults, and pregnant women have distinct requirements. Achieving the recommended daily intake through a combination of foods and, if necessary, supplements ensures optimal immune support.

According to the National Institute of Health, the RDA for Vitamin C across various ages is 

0–6 months40 mg*40 mg*
7–12 months50 mg*50 mg*
1–3 years15 mg15 mg
4–8 years25 mg25 mg
9–13 years45 mg45 mg
14–18 years75 mg65 mg80 mg115 mg
19+ years90 mg75 mg85 mg120 mg
Smokers Individuals who smoke require 35 mg/day more vitamin C than nonsmokers.

Interactions with Other Nutrients

Vitamin C doesn’t work in isolation; its interactions with other nutrients influence its effectiveness. 

  1. Vitamin C and Vitamin E: Vitamin C helps regenerate Vitamin E, another powerful antioxidant. When Vitamin E neutralises free radicals, it becomes oxidised, and Vitamin C steps in to restore its antioxidant properties. This interaction enhances the overall antioxidant capacity of the body, providing better protection against oxidative stress.
  2. Vitamin C and Iron: Vitamin C enhances the absorption of non-heme iron (the type of iron found in plant-based foods) from the digestive tract. It converts iron into a more absorbable form, facilitating its uptake. Combining Vitamin C-rich foods with iron sources improves iron bioavailability, making it especially important for individuals with vegetarian or vegan diets.
  3. Vitamin C and Zinc: Vitamin C facilitates zinc absorption in the intestines and supports the maintenance of its structural integrity. Zinc, in turn, influences the absorption and utilization of Vitamin C. This interaction is vital for immune function, wound healing, and DNA synthesis, as both Vitamin C and zinc play crucial roles in these processes.
  4. Vitamin C and Vitamin A: Vitamin C supports the conversion of provitamin A carotenoids (found in fruits and vegetables) into active Vitamin A. This conversion is essential for maintaining vision, immune function, and skin health. The collaboration between Vitamin C and Vitamin A promotes optimal functioning in various physiological processes.
  5. Vitamin C and Vitamin B12: Vitamin C may enhance the absorption of Vitamin B12, especially in individuals with low stomach acid or compromised digestive function. This interaction can benefit individuals at risk of Vitamin B12 deficiency, such as older adults or those with certain medical conditions.
  6. Vitamin C and Copper: Vitamin C is involved in the absorption of copper in the gastrointestinal tract and assists in its transport within the body. Copper is essential for the formation of red blood cells, connective tissues, and the function of enzymes, making the collaboration with Vitamin C crucial for these processes.

Understanding these interactions underscores the importance of a well-balanced and varied diet. Incorporating a diverse range of nutrient-rich foods ensures that these synergistic relationships contribute to overall health and vitality.


In the grand tapestry of nutrition, Vitamin C emerges as a vibrant thread, weaving its way through the fabric of our immune health. You can have your daily dose of this marvellous nutrient by taking Route2Health’s Vitamin C supplement that provides 1000 mg of the nutrient.

3. Can Vitamin C prevent all illnesses?

Vitamin C is a valuable immune booster, but it doesn’t guarantee complete immunity. A balanced lifestyle is key to overall health.

4. What are the signs of Vitamin C deficiency?

Fatigue, muscle weakness, and joint pain are common signs. Consult a healthcare professional if you suspect a deficiency.

5. How can I incorporate Vitamin C into a vegetarian or vegan diet?

Citrus fruits, berries, and vegetables like bell peppers and broccoli are excellent sources of Vitamin C for vegetarians and vegans.
