How much to eat ascorbic acid. Vitamin C for colds, what loading dose of ascorbic acid is needed. Dosage of ascorbic acid during pregnancy

One of the most important elements for the normal functioning of the body is; how much vitamin C can be taken per day, not everyone knows. It is believed that this vitamin is very useful and vital for humans, but its wrong dosage can lead to bad consequences.

According to its properties, ascorbic acid is very similar to glucose. This is also an organic compound that is necessary for the bone and connective tissue of the human body. Vitamin C is a powerful antioxidant that slows down oxidative processes in tissues and organs. A large dose of ascorbic acid is found in fresh vegetables and fruits, most of all in sour berries and citrus fruits.

This compound was discovered at the beginning of the twentieth century, but even before that time, mankind suspected that the insufficient daily requirement of vitamin C was fraught with such a terrible disease as scurvy. Lack of ascorbic acid leads to insufficient production of collagen and, as a result, tissue destruction. Most sailors suffered from scurvy. They did not eat fresh fruit for several months. Mass diseases of scurvy occurred during lean years and wars, when there was not enough food. In the modern world, scurvy is much less common. The lack of ascorbic acid is experienced by residents of the north and desert regions, sailors, and prisoners.

Why does the body need ascorbic acid?

Vitamin C is perhaps the most essential trace element for the human body. Since ancient times, ascorbic acid has been considered a good help for the main treatment of many colds and infectious diseases. Vitamin C is not a medicine and cannot cure or even alleviate the disease on its own. Ascorbic acid can be taken to support and prevent the body during the growth of colds.

Recent studies have shown that chemically derived ascorbic acid does not have such a positive effect as the vitamin found in fruits and berries.

There are several functions of ascorbic acid that many people are not aware of.

Healing and restorative functions. Ascorbic acid favorably affects the production of collagen. The fibers of this element are responsible for the condition of the skin, bones and connective tissue. With an insufficient amount of acid in the body, wounds heal much more slowly. Vitamin C is also needed for people with fragile bones prone to frequent fractures.

Vitamin C as an antioxidant. With a lack of ascorbic acid in the human body, redox processes can be disturbed, veins and arteries become clogged with dangerous cholesterol. Vitamin C literally dissolves plaques that can lead to clogging of blood vessels, reduces their elasticity and increases the possibility of thrombosis.

hematopoietic function. the body absorbs iron worse, which leads to anemia - weakness, decreased immunity, and inhibition of the basic functions of the body.

cleaning function. Ascorbic acid in large doses must be taken by people whose work is associated with heavy metals, as well as residents of large industrial areas. Vitamin C breaks down and removes compounds of chromium, lead, mercury, etc. from the body.

Restorative function. By increasing the release of interferon and antibodies to many diseases, ascorbic acid improves immunity and is a prophylactic in the fight against cancer.

metabolic function. It has been proven that when consuming citrus fruits, the body's metabolism increases significantly, metabolic processes are accelerated, and adipose tissue is split.

Daily requirement for vitamin C

The daily need for ascorbic acid depends on many indicators: age, gender, body condition, previous diseases, the epidemiological situation in society, and the need for other vitamins.

The daily intake of vitamin C is more than other vitamins. This is due to the great need and participation of ascorbic acid in many body processes. It is necessary for the absorption of other vitamins and minerals. The daily requirement of an adult is 100 ml (for men) and 75 ml (for women). A slight excess of consumption cannot lead to pathologies in the body and cause severe hypervitaminosis. Conversely, the maximum dose of pure ascorbic acid may be increased to 1 g per person per day in the following cases:

increased physical activity at work or due to sports training;
the period of acute respiratory diseases (the period of frequent colds - from late October to December and from late February to April);
during an influenza epidemic;
with alcohol and nicotine addiction;
during pregnancy and lactation, especially if several children are expected and the mother's body requires not a double, but a triple norm of vitamin C.

Usually ascorbic acid is sufficient in fresh fruits and berries, juices, compotes and fruit drinks. It is enough for children to eat a few citrus fruits, apples or a handful of berries per day to prevent vitamin C vitamin deficiency. In some cases, the acid is not enough, its dosage can be increased with the help of special preparations. This is ascorbic acid in the form of small spherical dragees for resorption, as well as vitamin C with glucose. Vitamin C may be present in some medicinal and prophylactic products as an auxiliary element.

Additional doses of vitamin C in the form of ascorbic acid tablets can be prescribed:

with frequent colds and flu;
with a lack of other vitamins and malnutrition;
small children with a lag in growth from their peers;
with long-term complex infectious diseases (fever, chronic infection, weakening of the body after prolonged use of antibiotics);
with burns and other skin lesions;
with some diseases of the gastrointestinal tract;
after operations and injuries;
after severe stress;
during pregnancy and especially after childbirth;
in the treatment of alcohol and nicotine addiction.

Ascorbic acid plays an important role in the functioning of our body. This vitamin is important not only for the functioning of the immune system. We draw part of ascorbic acid from food, but sometimes we have to take pharmaceutical products containing such an element. Do you know how many ascorbic acid you can eat per day?

Without vitamin C, it is impossible to imagine the full-fledged work of the human body at any age. Sweetish taste with a slight sourness leaves no one indifferent. And often both children and adults can gobble up a dozen dragees at once. And how many pills of ascorbic acid can be taken per day? The amount of ascorbic acid allowed to be taken in one day differs depending on the age category and can vary from 40 to 90 mg.

Admission rules:

newborns under the age of one year - 40-50 mg;
children aged one to three years - 40 mg;
from four to eight years - 45 mg;
up to 13 years - 50 mg;
from 14 to 18 years old - 65-75 mg;
older age - from 75 to 90 mg.

Moreover, representatives of the strong half of humanity aged 14 years and older require more ascorbic acid to satisfy the body's daily need for this vitamin.

And how many ascorbic acid can a child eat per day? Care must be taken to ensure that the child does not overeat. Of course, nothing terrible will happen even from eating 50 dragees; in extreme cases, an allergic reaction may occur.

But if you systematically exceed the allowable daily dosage, then the absorption of vitamin C will decrease and the substance that has entered the body will be excreted almost in full with urine.

Important! Doctors warn that the abuse of ascorbic acid can cause the development of negative consequences. Therefore, at first glance, harmless pharmacy goodies still need to be taken in doses.

In some cases, the daily dosage can be exceeded. So, for example, the established norm will not be enough for a smoking person. This addiction destroys vitamin C and there is an acute shortage. Also, a deficiency of ascorbic acid can be observed in women during the period of gestation. But an increase in the daily norm is always better to coordinate with a specialist.

If we talk about a pharmaceutical product, then it is produced from glucose. Basically, we draw such a substance from food. The concentration of ascorbic acid in different treats is different, but most of all this component is found in fruits and vegetables.

Everyone, without exception, needs ascorbic acid in the off-season, when the body is weakened and the immune system needs support. In this case, doctors advise taking an additional pharmacy drug in order to regularly meet the body's daily need for this vitamin.

List of indications:

ailments of an infectious nature;
intoxication of the body;
cholecystitis;
radiation disease;
stomach ulcer;
helminthic invasions;
burn wounds;
mental or physical fatigue.

A person, even without a medical education, will be able to determine when his body is in dire need of ascorbic acid. There are certain signs that indicate a deficiency of ascorbic acid.

Signs:

frequent incidence of viral and acute respiratory ailments;
excessive fatigue;
constant sleepiness;
the appearance of wounds on the skin and cracks;
hair loss;
dullness of curls;
pain and discomfort in the muscle and joint tissue;
gum disease;
sudden mood swings;
nervousness;
excessive irritability.

If a person shows at least a few signs of the above, it is likely that his body lacks vitamin C. This means that such a component will have to be drawn from pharmaceutical products, observing the prescribed dosage.

Vitamin deficiency is just as bad as too much. If you eat ascorbic acid in an unlimited amount, uncontrollably, this will lead to the accumulation of excess vitamin C in the body and provoke the appearance of side effects.

As medical practice shows, the primary symptoms appear after a couple of hours after taking a huge amount of ascorbic acid. At first, there is a feeling of anxiety that arose suddenly, dizziness, as well as pathological weakness. After a short time, the heart rate increases.

Side effects:

bouts of nausea;
vomiting reflex;
excessive accumulation of gases in the intestinal cavity;
insomnia;
flatulence;
excessive excitability;
rashes on the skin.

All excess from our body, as a rule, is excreted through the urinary system. If there is no failure in the work of the kidneys, then the consequences of overeating ascorbic acid may not occur. But this does not mean that this can always be practiced. These are isolated cases.

Complicated consequences

Some people take vitamin complexes or individual elements on the principle: the more the better. If, with a single overdose of ascorbic acid, side effects occur for some time, which are not difficult to cope with, then regular consumption of vitamin C in excess of the norm can lead to the development of serious consequences for the body.

With an excess of ascorbic acid, the work of internal systems and organs is disrupted. With a sharp deterioration in well-being, doctors advise immediately performing a gastric lavage and provoking an artificial gag reflex.

Effects:

hormonal imbalance;
lowering the level of digestibility of ascorbic acid by the body;
persistent intolerance to the vitamin component;
increased blood pressure;
failure of the cycle of menstruation;
violation of the functioning of the pancreas and kidneys;
exacerbation of gastric ulcers or gastritis;
blood clotting disorder.

As you know, vitamin C is one of the most important vitamins involved in almost all life processes of the human body. It acts as the main assistant in the fight against colds, perfectly strengthens the immune system and improves metabolism. The main "carrier" of this vitamin is ascorbic acid - the main acidic element in the human body.

Content:

Since ascorbic acid is directly involved in almost all vital processes of the body, its benefits can be fully appreciated when there is a shortage of it. Namely, symptoms such as pale skin, constant fatigue, poor sleep and appetite, frequent colds, decreased immunity and pain in the limbs, in most cases indicate that the body lacks acid in the required volumes.

Regular intake of vitamin C contributes to:

strengthening the immune system;
normalization of cholesterol levels;
prevention of diseases of the respiratory system;
increase hemoglobin and improve blood composition;
strengthening the cardiovascular system;
improving the general condition of the body, including skin, hair and nails;
body rejuvenation.

IMPORTANT! Ascorbic acid is part of almost all drugs that contribute to the rapid recovery of the body. However, it can even be harmful if used incorrectly, without adhering to certain dosages.

Dosage of ascorbic acid for colds or how much ascorbic acid can be eaten per day

Before using ascorbic acid, you need to familiarize yourself with some of the nuances. Vitamin C can be used in three varieties: tablet form, intramuscularly or intravenously.

IMPORTANT! The daily maximum dosage for each vitamin variety should be prescribed by a qualified physician.

Of course, ascorbic acid is most often prescribed in tablets, since it is more pleasant and comfortable to take it in this form, both for children and adults. The dose of the vitamin depends on the age and body weight of the person. It is better to use it after meals.

As a rule, the daily dose of ascorbic acid required for a person ranges from 0.05 g to 100 mg. However, it should increase with increasing physical activity, during colds (infectious) diseases, during pregnancy, emotional and mental stress. The therapeutic dose of vitamin per day is from 500 mg to 1500 mg.

Ascorbic acid dosage for adults:

In tablets. For the prevention and general maintenance of ascorbic acid in the body, it is prescribed to adults at 0.05 g - 0.1 g twice a day. During treatment, the dose of vitamin C is almost doubled - 1 tablet 3 times a day.
In dragee. The maximum possible dose of ascorbic dragees for adults is 1-2 pieces of 0.05 g each. For medicinal purposes, the number of dragees can be increased to 5 per day.
In powder form. For prophylactic purposes, vitamin C in powder is taken: from 50 ml to 100 ml per day, during treatment: from 300 ml to 500 ml. At the same time, 1000 mg of the powder is dissolved in 1 liter of pure water and taken after eating.
in ampoules. In the case of intramuscular (intravenous) use, a 5% solution of vitamin (sodium ascorbate) is used. The therapeutic dose is 1-5 ml from one to three times a day. As a rule, for the prevention of deficiency, tablet forms of ascorbic acid are used or in the form of dragees.

Ascorbic acid during pregnancy

Ascorbic acid is one of the first drugs prescribed to pregnant women. It affects many processes associated with the normal growth and development of the baby, and is also an excellent prevention of possible bleeding during childbirth. The maximum allowable dose for women in an "interesting" position in the second and third semesters is 60 mg.

IMPORTANT! An overdose of the drug during pregnancy (especially in the first trimester) has a very bad effect on the health of the baby and can lead to the development of ascorbic disease, scurvy and, in rare cases, abortion.

How to take vitamin C for pregnant women:

In tablets. If there are no contraindications, then pregnant women should take 2 to 4 tablets per day (1 tablet - 25 mg). In the first months, the daily intake of the vitamin should not exceed 60 mg.
In dragee. During pregnancy, it is recommended, starting from the second semester, to take 1-2 tablets of vitamin C, where one tablet contains 50 mg of acid.
In powder form. During the period of gestation and lactation, no more than 60 ml and 80 ml of vitamin C solution should be consumed, respectively. It is necessary to prepare the solution, strictly following the instructions: dissolve 2.5 g of the powder in 2.5 liters of clean boiled water. Drink after meals.
in ampoules. For injections, a 5% acid solution is used. Pregnant women are prescribed 1-1.5 ml of a 5% solution once a day (1 ml of the solution contains 50 mg of ascorbic acid).

IMPORTANT! During pregnancy, the need to take ascorbic acid, the dosage and duration of use is prescribed exclusively by a doctor!

Ascorbic acid dosage for children

- In tablets. Therapeutic dose for children from 3 to 7 years - 2-4 tablets (50-100 mg) per day, for children aged 7 to 10 years - 4 tablets (100 mg) per day, for children from 10 to 14 years - 4-6 tablets (100-150 mg) per day. Askorbinka should not be given to children under 3 years of age. For prevention, vitamin C should be consumed by children from 3 to 14 years old, 1 tablet per day.
- In dragee. The recommended professional dose for children over 5 years old is 1 tablet per day, with medical therapy - 2-3 tablets per day.
- In powder form. For prophylactic purposes, children over 6 years of age are recommended to use the drug after meals, in the form of a ready-made solution up to 50 ml per day. The therapeutic dose is up to 10 ml per day.
- In ampoules, children are prescribed: at the age of 6 months - 0.4-0.6 ml of 5% solution, 6-12 months - 0.7 ml of 5% solution, 1-3 years - 0.8 ml of 5% solution, 4-10 years - 0.9 ml of a 5% solution, 11-14 years old -1 ml of a 5% solution, over 15 years old - 1.2-2 ml of a 5% solution once a day.

As mentioned above, ascorbic acid is an essential vitamin for human health, taking part in almost all life processes. Remarkably, vitamin C is also important for animals, including cats, dogs, pigs, birds, horses, etc. It improves immunity, removes toxins, normalizes metabolism, and is also indicated for fractures, injuries, poisoning, pathologies of the kidneys, intestines, etc. Often "ascorbic acid" is prescribed to pregnant animals.

Vitamin C is given to cats or dogs in three ways: intramuscularly, intravenously, or injected under the skin. Apply a 5% solution of "ascorbic acid" in ampoules or in powder. The dosage is prescribed exclusively by a veterinarian, taking into account the weight of the animal and its condition. As a rule, the dose is 0.1-0.2 ml per 1 kg of body weight. In powder, animals are prescribed from 50 to 200 mg of weight per 1 kg of weight. Powdered vitamin C is given mixed with feed.

Vitamin C in combination with glucose is a powerful natural antioxidant that takes part in many biochemical processes in the body. It has a beneficial effect on the state of the liver and kidneys, removes toxins, has antihistamine and anti-inflammatory properties, activates blood circulation processes, improves iron absorption and speeds up metabolism.

Usually, ascorbic acid paired with glucose is prescribed to increase the protective functions of the body, for the proper production of adrenal and thyroid hormones. The dose of the drug is prescribed by the doctor, based on the age, weight of the person, his condition and the complexity of the disease. For preventive purposes, adults and children from 14 years old are recommended to take from 50 to 100 mg per day, children under 14 years old - up to 50 mg per day. Therapeutic maximum allowable dosage of vitamin C and glucose for children from 6 to 14 years old is no more than 150 mg per day (2-3 tablets per day), for adults - 50-100 mg of the drug 3 times a day. The duration of treatment should not exceed more than two weeks.

What threatens an overdose of ascorbic acid - overdose symptoms

It should be noted that an overdose of ascorbic acid is no less dangerous than its lack. And all because, due to its large accumulation, intoxication of the body occurs, or simply poisoning.

IMPORTANT! The dosage of vitamin C must be reduced or completely eliminated when adding a large amount of citrus fruits to your daily diet - tangerine, orange, grapefruit, greens - parsley, dill, spinach, berries - red and black currants, gooseberries.

You should be alert for symptoms such as:

nausea, frequent dizziness, general weakness of the body;
irritability and increased nervousness;
bad sleep;
bowel problems: pain, cramps, disorders;
vomiting, stomach cramps;
skin rashes.

because they may indicate an excess of vitamin C in your body. In order to prevent an overdose of the vitamin, it is very important to establish for yourself an individual daily intake of the drug and balance the intake of ascorbic acid with products containing it in large volumes.

Ascorbic acid was first discovered in its pure form by the chemist Zilva at the beginning of the last century, who synthesized it from lemon juice. According to its main characteristics, it is a white crystalline substance, sour in taste and rapidly decomposing in water.

An organic compound (C 6 H 8 O 6), or vitamin C, is found in many plants in varying amounts. With its help, many oxidative and reduction processes occur, and with a lack of vitamin in the human body, the development of scurvy, hypovitaminosis, which entails other disorders, is possible. It is needed to produce lymphocytes that destroy infected cells and maintain the function of white blood cells (leukocytes). The ability of the body to cope with infections depends on their readiness.

Vitamin C must be constantly supplied to the human body.

The consumption of ascorbic acid is especially relevant in the following cases:

poisoning by chemicals when inhaled;
development of hypovitaminosis;
a growing organism, since the absence of a useful substance can lead to pathology of the skeletal structure;
during pregnancy;
with active smoking, as tobacco removes it from the body.

Beneficial features

When using vitamin complexes, many people do not fully realize how useful ascorbic acid is, and often neglect it, preferring more expensive drugs.

The beneficial properties of ascorbic acid include the following:

It helps to increase the endurance of the body.
Performs a protective function in colds, participating in collagen biosynthesis and in the production of lymphocytes that destroy infected cells.
Vitamin C contributes to the regulation of carbohydrate metabolism and blood clotting.
Acceleration of the process of wound healing and bone fusion.
The participation of vitamin C in the synthesis of collagen protein promotes the growth of muscle, bone, and cartilage cells.
As an antioxidant, it removes toxins from the body by regulating redox processes. Including promotes the removal of heavy metals (copper, lead) from the body.
Restoration of exocrine function of the pancreas, thyroid glands.
Regulation of hematopoietic processes, normalization of capillary permeability.
Reduction of intoxication of the body with frequent use of alcohol and smoking.
Serves as a general tonic for various diseases.
It has a positive effect on mental performance, mental state, helps to cope with stress.
Promotes the activation of enzymes in the liver, increasing the ability to cleanse the body.
Normalizes cholesterol levels.
Helps to maintain firmness and elasticity of the skin, protecting against premature aging.
Participates in synthesis.

Vitamin C is included in the complex therapy in the treatment of many diseases. It is very important to give it in tablets to children, since a lack of vitamin C in a growing body can affect changes in the skeletal structure.

Warnings and indications for use

How much and how to take ascorbic acid? The daily norm is 100 mg. The synthetic form of the vitamin should be taken after meals.

By itself, vitamin C is not dangerous, but if it is abused, an allergic reaction is possible - the appearance of itching, a small rash and other phenomena. If there are problems with the gastrointestinal tract, then vitamin C, or ascorbic acid, consumed in large quantities, can lead to a number of complications. An overdose of ascorbic acid can cause abdominal pain, diarrhea, indigestion.

Contraindications to taking ascorbic acid are diabetes mellitus and thrombophlebitis: it has an identical composition with glucose, and this can provoke an increase in blood sugar levels. Caution should be taken in its use for those who have renal failure, anemia, leukemia, and progressive malignant tumors. Given that ascorbic acid has contraindications, the intake and daily dose should be determined by the doctor.

Speaking about the benefits of using vitamin C, we must not forget that its excess in the body can lead to the appearance of:

diarrhea;
nausea;
vomiting;
heartburn;
bloating and spasm;
headache;
insomnia;
the formation of kidney stones.

In large doses, ascorbic acid will work not for good, but for harm. Uncontrolled use can contribute to the appearance and accelerate the development of atherosclerosis, in children - to injure the renal tubules, provoking the development of nephrolithiasis. Therefore, you need to know what daily rate is suitable for each person. The dosage of the norm differs for adults and children, which is why specialist advice is needed.

Dosage

To consume vitamin C per day, according to experts, you can at least 90 mg for men and 75 mg for women. More accurate dosages of the substance per day for people engaged in physically hard work, professional sports, during pregnancy or breastfeeding are established by the doctor, taking into account the characteristics of the body.

Daily doses for younger patients are as follows: adolescents take 65-75 mg, children - about 35-50 mg. It will be convenient to use with a content of 25 mg of vitamin in 1 pc. The recommended maximum daily dose is 2000 mg, but some modern scientists advise increasing the daily dosage to 3000 mg in order to prevent cancer.

This useful vitamin is, and therefore does not accumulate in the body and is excreted in the urine. So drink it, eat it or taken as tablets daily is recommended. He useful as recommended by doctors dosage people of all ages, with the exception of certain conditions. If an adult or child ate fruits and vegetables rich in ascorbic acid regularly in a healthy state, then at the first symptoms of respiratory diseases, it is necessary to increase their number and supplement the intake of synthetic forms of vitamin C.

The presence of useful substances in natural products

Many vegetables and fruits are rich in ascorbic acid. If the need for a vitamin cannot be met with natural sources, additional drugs may be prescribed.

A large amount of ascorbic acid is found in the following products:

rose hip;
black currant;
sea buckthorn;
apples;
red bell pepper;
orange, lemon, tangerine, kiwi;
cabbage, carrot, tomato, cucumber;
dill, parsley.

Abuse of the synthetic form of ascorbic acid will only bring harm. And fruits and vegetables can be eaten in almost unlimited quantities, if there are no allergies or other contraindications. Eating right, you can provide the body with useful substances in sufficient quantities.

Ascorbic acid is a chemical organic compound belonging to the group of water-soluble vitamins. The chemical compound was isolated in its pure form in 1928 by the Hungarian scientist Albert Szent-Györgyi. Ascorbic acid is mainly used in the pharmaceutical and food industries. In the first case, as a drug or dietary supplement, in the second case, as a preservative.

Importance of Vitamin C

Vitamin is very important for the human body. The main physiological processes in which the substance takes part are:

Regulates oxidative and reduction processes.
Takes part in the synthesis of catecholamines, collagen, steroid hormones.
Stimulates the exchange of folic acid and iron.
Participates in the processes of blood clotting.
Strengthens the walls of blood vessels and normalizes capillary permeability.
Increases resistance to bacterial and viral pathogens.
Increases stress resistance.
Reduces the risk of atherosclerosis by affecting lipid (fat) metabolism.

Need for a vitamin

Ascorbic acid does not have the ability to accumulate in the body, so a constant supply of the vitamin from the outside is required. The need for a vitamin is individual for each person and largely depends on a number of factors: age, gender, health, physiological state, intensity of physical activity, and the presence of bad habits. Average daily doses are:

babies up to a year - 30-35 mg;
children from one year to 10 years - 40-45 mg;
adolescents from 11 to 18 years old - 50-60 mg;
adults - 60 mg.

The need for the vitamin increases during pregnancy and during breastfeeding. Ascorbic acid stimulates the production of elastin and collagen, and, therefore, is a good preventive measure for the development of vein diseases and skin defects (stretch marks). Since the substance is able to influence the elasticity of the skin, the extensibility of tissues increases during the course, which is important in the process of childbirth. Also, sufficient intake of the vitamin by a pregnant woman ensures the normal development of the unborn child. The need for ascorbic acid in pregnant women is 70-80 mg per day.

It is also important to take a vitamin during breastfeeding. With breast milk, a nursing mother gives the baby most of the vitamins, including vitamin C. Therefore, in order to provide the baby with a sufficient amount of ascorbic acid and prevent deficiency in the mother's body, it is necessary to consume up to 100 mg of vitamin per day.

Hypovitaminosis - lack of vitamins

With a lack of ascorbic acid in the body, regardless of age, gender and physiological state, hypovitaminosis develops, which can manifest itself as follows:

Decrease in the body's defenses, which leads to frequently recurring respiratory infections.
Increased fatigue, drowsiness.
Long healing of small wounds and cracks in the skin.
Brittleness, dullness and hair loss.
Pain in joints and muscles.
The appearance of bruises and hemorrhages, even with minor injuries.
Inflammatory gum disease, which can lead to tooth loss.
Bad mood, nervousness, depression.

Sources of ascorbic acid

These symptoms can be especially acute in the autumn-spring period. When hypovitaminosis occurs, the appointment of a vitamin in the form of medicines is indicated. On the modern pharmaceutical market there are quite a lot of drugs, which include ascorbic acid.

The most commonly prescribed drugs for hypovitaminosis:

Ascorbic acid in ampoules in the form of a solution for intramuscular and intravenous injections. It is prescribed for therapeutic purposes in conditions associated with acute vitamin C deficiency, in diseases of the stomach and intestines, if necessary, parenteral nutrition.
Ascorbic acid, dragee. The dosage form contains 50 mg of vitamin C. It is prescribed for adults and children during the period of seasonal respiratory infections, during the treatment of viral infections, as well as for pregnant and lactating women to prevent hypovitaminosis.
Ascorbic acid with glucose. The composition of each tablet contains 100 mg of vitamin C. The indications are the same as for the drug in the form of a dragee.
Vitamin C, effervescent tablets containing 1000 mg of ascorbic acid. One tablet contains a loading dose of ascorbic acid. The drug is recommended for use at the first signs of an acute viral disease (ARVI). 1000 mg is the maximum dose recommended for taking colds.

Ascorbic acid is also part of some combination drugs that are used to treat various pathologies:

Sorbifer Durules. The drug Iron sulfate and Ascorbic acid. Assign a remedy for iron deficiency in the body. In the presence of vitamin C, iron is absorbed much better.
Askorutin. The drug contains Ascorbic acid and Rutozid. It is prescribed for vascular diseases, ulcerative skin lesions, metabolic disorders.
Various combined multicomponent preparations for relieving symptoms of influenza and SARS. With a cold, vitamin C stimulates immune processes, thereby helping the body fight infection. These drugs include Maxicold, Theraflu, Vicks Active Symptomatic, Rinzasip, Coldrex and others.

In addition to the above drugs, almost all vitamin-mineral complexes contain Ascorbic acid in their composition. Ascorbic acid is also found in most dietary supplements.

In addition to synthetic sources of vitamin C, ascorbic acid is found naturally in many foods.

The main foods containing vitamin C are: red bell pepper (260 mg), strawberries (67 mg), lemon (55 mg), sorrel (65 mg), cauliflower (70 mg), tangerine (35 mg), gooseberries (45 mg), red currant (40 mg), spinach (35 mg), white cabbage (45 mg), orange (55 mg), tomatoes (40 mg), apples (35 mg), cranberries (20 mg), dried rose hips ( 1200 mg), turnip (25 mg), green onion (30 mg), radish (45 mg), melon (15 mg). This number of mg in the products is based on 100 g of the product.

The daily dose of ascorbic acid can enter the body in the process of nutrition, subject to the rules of rational nutrition:

Eat more fresh vegetables and fruits without heat treatment.
Drink freshly prepared vegetable and fruit juices without adding salt or sugar.
Additionally fortify food by adding ascorbic acid, or take complex vitamin preparations, especially in autumn and spring.

During the heat treatment of products in the process of cooking, Ascorbic acid is partially destroyed. Most of the vitamin is stored in the preparation of dishes by steam processing, baking and without heat treatment. The destruction of vitamin C occurs during prolonged boiling of the dish and frying.

Ascorbic acid is useful for children and adults in age dosages. Daily intake of vitamin C during a period of high morbidity will help adults and children of all ages survive the cold season without colds and ailments.

The formula C6H8O6 is not known to all people, but perhaps everyone has heard about ascorbic acid - vitamin C. It is a water-soluble vitamin that is involved in a variety of oxidative and reduction processes in the body. The benefits of ascorbic acid are invaluable, because it even plays an important role in the formation of deoxyribonucleic acid.

Although people could not do without vitamin C even in ancient times, it was only in 1928 that scientists managed to obtain it in its pure form. But four years later, it was also possible to prove that the lack of ascorbic acid is fraught with many diseases, including scurvy.

Dosage of Vitamin C

Doctors say that men need at least 90 mg of vitamin C per day, but women need 75 mg. In some cases, the dosage of the vitamin can be significantly increased (up to 1000 mg per day). So, athletes, as well as people who work in physically hard work, the intake of the vitamin can be increased. The need for this substance also increases during pregnancy and lactation.

The size of the daily dose of ascorbic acid is increased to 1000 mg and at the first manifestations of respiratory diseases. The maximum daily dose of the vitamin should not exceed 2000 mg. An overdose is possible when taking 12,000 mg per kilogram of a person's weight.

Interestingly, some scientists argue that for the prevention of cancer, it is necessary to increase the intake of vitamin C to 2000-3000 mg per day.

Sources of ascorbic acid

In pharmacy kiosks, you can find vitamin C in a concentrated form - in tablets. However, natural products are rightfully considered the best sources of this substance. It is in this case that you can count on the fact that the benefits of ascorbic acid will be maximum.

Most of the vitamin C in these foods:

rose hip;
green parsley;
black currant;
spinach;
sea buckthorn;
apples;
red bell pepper;
citrus fruits (oranges, lemons, tangerines);
wild garlic;
dill.

In small doses, this vitamin is also found in other fruits and vegetables, so you need to include them in your diet. At the same time, the dose of ascorbic acid received by their products is sufficient to fill the daily need of the body for this substance.

With a respiratory disease, you need to increase its consumption; for this, pharmacy preparations are purchased.

The benefits of ascorbic acid

Why does the body need ascorbic acid?

Recent studies have shown that chemically derived ascorbic acid does not have such a positive effect as the vitamin found in fruits and berries.

There are several functions of ascorbic acid that many people are not aware of.

hematopoietic function. the body absorbs iron worse, which leads to anemia - weakness, decreased immunity, and inhibition of the basic functions of the body.

Restorative function. By increasing the release of interferon and antibodies to many diseases, ascorbic acid improves immunity and is a prophylactic in the fight against cancer.

metabolic function. It has been proven that when consuming citrus fruits, the body's metabolism increases significantly, metabolic processes are accelerated, and adipose tissue is split.

Vitamin C is an antioxidant. One of the purposes of this vitamin is the regulation of redox processes in the body. This substance also controls coagulation, regulates the permeability of the walls of blood vessels, and exhibits anti-inflammatory and anti-allergic effects.
Is ascorbic acid necessary and why? The description of this item will answer all your questions.

He is an agent of protecting the body from the results of stress. Multiplies the healing and restorative work, raises the level of resistance to infections.
Significantly reduces the effects of a variety of allergens. There is evidence that it can be used to prevent cancer.

It is well known that in cancer patients, due to the exhaustion of useful reserves, signs of vitamin deficiency often appear, which requires their additional intake.
Ascorbic acid promotes better absorption of calcium and iron, removal of harmful elements from the body.

It is essential that, in the presence of the required volume, the stability of vitamins B1, B2, A, E, pantothenic and folic acids is fundamentally enhanced.
This substance protects low-density cholesterol from oxidation, and hence the blood vessels from cholesterol plaques. Ascorbic acid is an invaluable assistant in overcoming the effects of stress and physical stress.

The adrenal glands, which secrete hormones so necessary to influence stress, contain more sodium ascorbate than any other organ.
This vitamin promotes the production of stress hormones and keeps the body free from unhealthy metabolic factors.

Since this substance, the element is water-soluble, it is not reserved and its excess is removed with urine - therefore, it must be taken with food every day.
