Many are aware that vitamin C is good for the body. Also, many have heard that if a runny nose, a cough, a rise in temperature has begun, then the best remedy would be to drink vitamin C. And even better - before the upcoming rise in the incidence of colds, drink a vitamin complex as a prophylaxis. However, not all so simple.
Interesting fact: Ascorbic acid (or vitamin C) is an indispensable nutritional factor only for humans, monkeys, guinea pigs and bats.
Ascorbic acid is a natural antioxidant, it is important for the condition of the connective tissue, as it ensures the synthesis of collagen from procollagen (it is when this process is disturbed that a well-known, but today rare disease manifests itself - scurvy, when teeth fall out, gums bleed, and so on).
But what role does vitamin C play in immunity? It improves the immunological status of the body by enhancing the activity of immune cells. However, in the recommendations for the treatment of ARVI, based on the studies conducted, it was decided not to include vitamin C intake in the prevention of colds.
The fact is that vitamin C is a water-soluble vitamin. This means that it does not accumulate in the body. The body will retain exactly as much vitamin as is required - and not a single tissue will store it "in reserve", the surplus will simply be excreted with natural discharges. Therefore, it makes no sense to drink ascorbic acid before the cold season.
The same applies to vitamin complexes. If a person does not have a deficiency of some water-soluble vitamin (and most of them, except for four - A, D, E, K), then there will be no benefit from vitamin complexes. This is in addition to the fact that due to the peculiarities of the metabolism of vitamins, some of them can interfere with the absorption of others, which is often not taken into account in dietary supplements.
Vitamins are taken when they are deficient, and nothing more. Just like that, for "strengthening the body" they are unsuitable.
