Does the supposed immunostimulating action of vitamin C rest on scientific grounds?
The protective effect of vitamin C against infectious diseases is still controversial. On the other hand, it is clear that the deficiency of this vitamin, whose scientific name is ascorbic acid, is associated with a greater predisposition to infections, a symptom that was once found in people suffering from scurvy.
Various factors also increase the need for vitamin C, with a consequent risk of deficiency: stress, smoking, pollution, taking various medications (including some frequently used such as aspirin and oral contraceptives), alcohol and caffeine abuse, intense physical activity etc.
While the preventive action of ascorbic acid sometimes arouses some diffidence, its effectiveness in the treatment of infections has been demonstrated by more than twenty clinical studies.
Equipped with an antibacterial and antiviral action, this substance acts by stimulating not only the synthesis of white blood cells (responsible for the production of antibodies), but also that of interferon, which prevents the penetration of viruses into the cell.
It goes without saying that when it comes to prophylaxis or therapy with a nutrient, it is necessary to resort to doses far greater than those of the average requirement.
It is mostly recommended to take one gram of vitamin C as a preventive measure, more grams per day in case of full-blown infection, if possible from the onset of the first symptoms.
Some of you might think
I don’t understand how our body can benefit from supplementation with a vitamin which, in case of excess, is eliminated with urine …
It is true that water-soluble vitamin C is not stored by the body. However, it is equally true that fabrics can become impregnated with them like a sponge that soaks in water, without rejecting the slightest part of it until they have retained everything necessary to satisfy their needs which, as we have seen, increases in different situations.
Does Vitamin C Have Other Properties?
Absolutely Yes, many. To name just a few, it counteracts fatigue and stress, improves the assimilation of calcium and iron, strengthens blood vessels, accelerates wound healing, is effective against allergies, prevents premature aging and degenerative diseases (arthrosis, arteriosclerosis, cataract etc.).
