Is Vitamin C helpful in cold prevention?

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 provides the synthesis of collagen from procollagen (violations of this process manifest a well-known, but rarely occurring disease - scurvy, when teeth fall out, gums are bleeding, etc.).

But what role does vitamin C play for 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 on the basis of the studies conducted, it was decided not to include vitamin C 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. In the body, there will be exactly as much vitamin as is required - and not a single tissue will be stored “in reserve”, the surplus will simply be displayed with natural items. Therefore, before the cold season to drink ascorbic acid does not make sense.

The same applies to vitamin complexes. If a person does not have a deficiency of some water-soluble vitamin (and most of them, except 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 nature of the metabolism of vitamins, some of them may interfere with the absorption of others, which is often not taken into account in dietary supplements.

Vitamins are taken with their deficiency, and only. Just so, for "strengthening the body," they are unsuitable.
