How to take vitamin C with cold: recommended dose
Does Vitamin C help with colds? The common cold is the most common infection in the world of the upper respiratory tract, caused by a large group of viruses. Transmitted mostly by airborne droplets, pathogens penetrate the larynx, nasal cavity, pharynx, where they actively multiply and cause cell death. In parallel, into the blood are secreted toxins that cause intoxication, which is accompanied by fever, joint aches, headache and general malaise. Under normal immunity, a cold affects a person on average 1-2 times a year, with weakened body protection - from 3 to 4 times.
The role of vitamins in the cold
Vitamins in the cold season are a necessary component of quality treatment, as they:
- have immunomodulatory properties that accelerate the process of producing antibodies and destroying colds;
- does not allow the penetration of pathogens into epithelial cells;
- are involved in the repair of virus-damaged cells in the mucous membrane of the respiratory tract.
Does Vitamin C cure a cold?
Most useful is for colds of vitamin C, stimulating the synthesis of interferons, which are responsible for antiviral immunity. At one time it was even thought that he was able to cure a cold. Is it so? Myth, which arose in the 70's and encouraged parents to feed the children to "ascorbic" almost in place of sweets( in other words, for the common cold, vitamin C was used everywhere), was debunked some time ago. The results of the studies showed that in high doses ascorbic acid can shorten the duration of the disease by only half a day. That is, patients who took vitamin C during a cold, were ill as long as those who did without it. Therefore, it is unlikely that this tool plays a decisive role in the cure of the patient. More effective substance in the fight against pathogenic viruses by American scientists was recognized zinc, the use of which in increased dosage reduced the recovery time by almost 2 times.
Or helps quickly recover?
Nevertheless, such a disappointing conclusion, contrary to the generally accepted opinion, does not at all point to the fact that vitamin C is unhelpful for colds.
Ascorbic acid, which helps cells of the immune system to cope with infection more actively and is a powerful antioxidant, is necessary during the illness itself, as it facilitates the process of recovery. Vitamin E also works as an antioxidant in the body. If the task of ascorbic acid is to fight free radicals in the intercellular fluid, then vitamin E "hunts" them at the cellular level. The daily requirement for this element, contained in meat, liver, lettuce, nuts, is 10 mg.
Products containing vitamin C
Belief in the miraculous nature of vitamin C as a cold remedy is firmly present among parents, each of whom during the period of illness tries to fill the diet of the child with lemons and oranges - products containing ascorbic acid in their composition. This substance is a component not only in citrus fruits, but also in vegetables( melon, Bulgarian pepper, tomatoes, peaches), fruits( apples, apricots, peach), berries( strawberries, black currants).Of the products of animal origin, useful substance is rich in kidneys and liver. Also vitamin C is present in herbs: ocharynka, lucerne, hops, yarrow, parsley, raspberry leaves, peppermint, burdock root, fennel.
Many people mistakenly believe that vitamin C should be consumed in winter, at the height of the cold season. This is not correct, because in the off-season the body's strengths are also weakened and need reinforcement. The break can be done in the summer, with its abundance of greenery, fresh vegetables and fruits.
When should I take vitamin C?
It should be noted that daily intake of vitamin C reduces the risk of colds by 50%.The need for ascorbic acid occurs more often in comparison with other vitamins. This is because with cold manifestations such an element creates an acidic environment, uncomfortable for viruses. For prevention, a dosage of 15-20 mg is recommended. Shock dose of vitamin C for colds - 1000-1500 mg per day. The most effective for its use is the initial period of the disease, characterized by malaise, nasal congestion, and throat swelling.
Increased demand for vitamin C occurs:
- during pregnancy and lactation;
- increased physical exertion;
- restorative process after a serious illness;
- poisoning the body;
- the presence of the risk of infectious diseases.
Consequences of lack of ascorbic acid in the body
What is the danger of a deficiency in the body of ascorbic acid? The deficit of vitamin C is first of all indicated by the skin of a person who, literally before his very eyes, will begin to grow old and grow old. Also, the lack of ascorbic acid can be determined by prolonged healing of wounds, scratches and other mechanical damages. Ascorbic acid deficiency is still evident:
- muscle pain,
- general weakness,
- gum bleeding,
- suppressed state,
- small-point hemorrhages in the area of the hair follicles( most of the legs),
- tooth loss,
- pain in the areaheart,
- by hypotension( low blood pressure),
- by abnormalities of the stomach.
What dose of vitamin C for a cold is considered harmless to the body? The daily requirement for ascorbic acid for the male half of the population is 64-108 mg, for women this figure is 55-79 mg. At the first manifestations of the common cold, the recommended dose is up to 1200 mg of vitamin per day. But it is worth remembering that the abuse of this substance with normal nutrition can lead to an overdose, expressed in nausea, vomiting, diarrhea, headache, insomnia and excessive excitability. In some cases, the kidney and pancreas may be affected. Also, an excess of vitamin C negatively affects the tooth enamel and gastric mucosa. Therefore, in order to avoid possible complications, it is recommended to take it in the form of a drink, preferably through a tube.
