The importance of Vitamin C for the immune system

29 April, 2021

Immune system and Vitamin C

The immune system is essential for life: it represents a complex security system that makes use of organized components and mechanisms and is necessary to face various adversities. These defense mechanisms can be traced back to two main categories: non-specific immunity and specific immunity.

  • non-specific or innate immunity represents the first line of defense against aggression. It places the immune system in a state of alert and promotes the specific immune response. It also takes advantage of the natural barriers of our body such as the skin and certain types of tissues to prevent the entry of external agents;
  • specific, acquired or adaptive immunity represents a more targeted and effective response for the immune defenses. T lymphocytes and B lymphocytes are those directly involved.

This better response is maintained over time, allowing the immune system to respond more effectively whenever it encounters that particular danger or harmful agent.

Factors that put a strain on the immune system

Several factors can cause a lowering of the immune system and so can increase the risk of developing a disease, including:

  • stress: the correlation between psychophysical stress and lowering of the immune defenses is well known;
  • sleep disorders: sleeping poorly and badly can cause a decrease in immune defenses;
  • incorrect diet: a diet low in fruit and vegetables, and rich in fats and sugars can lead to a lack of vitamins and minerals, such as Vitamin C deficiency, and consequently a lowering of the immune system.

The best vitamin for the immune system: Vitamin C

The main nutrient for strengthening the immune system and preventing infections is Vitamin C. It was isolated in 1921 and extracted from pine needles, lemon, and green plants. Nowadays, Rosehip and Acerola are the reference plants, as after extraction they contain 40 to 80 times more Vitamin C than kiwi and citrus fruit. It is a water-soluble substance with a powerful immunostimulating and antioxidant action; the minimum recommended daily requirement is between 70 mg and 90 mg.

Vitamin C and the immune system

A function known to be attributed to Vitamin C is to modulate the immune response, especially in colds, for example by reducing the duration of the cold itself. The right amount of this substance through food is sufficient to reduce the risk of respiratory tract infections. However, in times of stress, fatigue, infections, surgery, exposure to cigarette smoke, its need increases, and it’s recommended to take it through a dietary supplement.

Being a substance very sensitive to oxygen, heat, and light, there is a risk that food, once cleaned and treated for large-scale distribution, will lose a lot of Vitamin C, leading to a vitamin deficiency. Having a specific effect against disease related to the respiratory tract, it is recommended to increase the intake of Vitamin C in particular during the winter period, where we generally eat less raw foods, especially fruit and vegetables.

Furthermore, Vitamin C supplements can be used in the treatment of various ailments:

  • Infections
  • Hypoimmunity
  • Presence of free radicals
  • Tendency to bleed
  • Anemia (Vitamin C is essential for the absorption of other nutrients such as iron, folic acid, vitamin E)
  • Fragility of the blood vessels
  • Vasculopathies
  • Disorders of the epicutaneous adnexa and tissue repair (Vitamin C is necessary for the formation, protection and stabilization of collagen)
