But do not forget that any industrial drug is a product of the pharmaceutical industry and can be classified as a drug.

Ascorbic acid poisoning can cause serious problems in the body and in some cases, when exceeded maximum dose, it can be just harmful. For a complete understanding of the benefits and harms of Ascorbic acid, one should understand its effect on a person.

Vitamin C, which is the main constituent of ascorbic acid, has the following effects:

• Helps regulate carbohydrate metabolism.
• It takes part in redox reactions occurring inside the cells of the body.
• Participates in the normalization of permeability blood vessels.
• It has a stimulating effect on the synthesis of steroid hormones.
• Provides protective functions of the immune system.
• Helps support collagen production.
• Helps strengthen tooth enamel bone tissue.
• Normalizes the process of blood clotting.

Vitamin C intake stimulates fermentation and preservation natural level hormones of the steroid group, which enables the body to cope with stressful situations. Since vitamin C serves as a natural antioxidant, its use helps the recovery process of the body's internal forces and leads to accelerated healing of small wounds or cracks, prevents the development of inflammation and slows down aging.

But these positive features are available only if correct reception. An overdose of ascorbic acid leads to negative consequences and even poisoning.

To whom is the reception contraindicated?

When taken properly, vitamin C cannot cause side effects or cause an allergy to ascorbic acid. But there is a category of people belonging to a peculiar risk group for whom taking Ascorbic acid is contraindicated or its use should be carried out with caution, be sure to monitor the daily dose in order to avoid consequences.

Symptoms indicating an overdose should be a signal to consume a large amount of fluid, which will help to quickly remove ascorbic acid from the body. If a single dose is exceeded, it is required to induce vomiting and clear the stomach, after which it is necessary to take an absorbent.

The use of vitamin C, which is the main component of the drug, is vital for the human body, especially during an epidemic of infectious or colds, in case of poisoning by combustion products and people who abuse alcohol.

But remember that vitamins are substances pharmacological group, which requires compliance with the established dosage during administration. Exceeding the norm can lead to negative consequences, many times greater than the beneficial effect.

Ascorbic acid is a compound organic nature having family ties with substances such as glucose. Ascorbic acid is one of the main acid elements in the human body. The functional abilities of ascorbic acid are aimed at recovery processes and improving the work of metabolic processes.

The main active element in the composition of ascorbic acid is vitamin C, which is essential vitamin to support the body and at a good level. That's why given acid often referred to simply as vitamin C. Ascorbic acid is often found in nature and is found in many fruits and some vegetables.

Ascorbic acid in its properties is a white or light yellow powder, which has a sour taste. In addition, this type of acid dissolves very well in liquids, giving a sour taste to the water in which it will be dissolved.

In 1932, when vitamin C was first discovered, huge plans were placed on its share. But experiments have shown that with the help of ascorbic acid, you can only support the human body and prevent many already clinical cases various diseases.

The main cases of the use of ascorbic acid:

• Usually, ascorbic acid is needed by people who have been poisoned by carbon monoxide or other harmful gaseous substances. In case of serious poisoning, ascorbic acid normalizes the processes associated with oxidation and restores the normal environment in the human body. In cases of poisoning, the dose of ascorbic acid can be up to 0.25 ml per 1 kg of body weight.

• The lack of vitamins during the change of seasons is also a reason for the use of ascorbic acid. It could be like medicinal product, as well as fruits and vegetables containing vitamin C, which must be added to the daily menu. This will help strengthen the immune system and make it easier to endure such a period.
• Pregnancy. During the period, many girls experience a lack of vitamin C. As prescribed by the doctor, the use of ascorbic acid is recommended. On average, a pregnant woman should receive 30% more ascorbic acid than before pregnancy.
• Smoking. As with carbon monoxide poisoning, smoking people an increased dose of vitamin C is needed. This is necessary to restore the acidic environment in the body.

The benefits of ascorbic acid

The benefits of ascorbic acid can be judged by the symptoms of its lack. Lack of adequate amounts of vitamin C can be seen in the following symptoms:

• Pallor skin;
• Weakened immunity;
• Increased wound healing time;
• Bleeding gums, loose teeth;
• General malaise;
• restlessness and poor sleep;
• Pain in lower limbs(especially heels and feet)

Ascorbic acid acts to prevent these symptoms from appearing. It will also be useful if available.

The harm of ascorbic acid

A quality preparation of ascorbic acid in itself is safe. But this does not mean that you can eat ascorbic acid in batches. A number of contraindications to this drug are still available. The basis of the problem is an overdose of vitamin C, in which there is nothing to worry about either, but this is only for healthy people, but for those who have stomach problems (gastritis, ulcers), the use of such an amount of acid can cause a number of complications.

Overdose of ascorbic acid

An excess of acid badly affects the condition of the stomach and digestive tract, corroding the walls of the stomach. This actual problem for people with indigestion.

If an overdose did happen, then it will be useful to know some of its consequences now.

For example, in pregnant women, metabolism can be disturbed or out of control, which can lead the mother and fetus to certain problems. Future child may become more susceptible to allergies, and the mother may develop stomach problems.

Side effects of taking ascorbic acid

Vitamin C, like all ascorbic acid, is water-soluble, which means that if you take more of it than the body needs, then the excess will simply be excreted. But it can cause indigestion, stomach pain, diarrhea, or cramps if taken in too much. If you plan to take additional vitamin C, you should increase the dose gradually over time to evaluate possible side effects.

What drugs are not compatible with taking ascorbic acid?

Ascorbic acid should not be used in combination with drugs that contain a large amount of iron, caffeine, vitamin B12, folic acid. More complete and detailed information about compatibility is better to read in the annotation, it is in each package.

What should you know before using ascorbic acid?

The use of ascorbic acid depends on specific factors. First, you need medical consultation, secondly, you need to buy ascorbic acid in tablets or liquids in pharmacies of a large network, as counterfeit drugs are increasingly coming across on the shelves.

Use this drug better after eating. Approximate doses for preventive treatment beriberi 50-100 mg for an adult per day. For children, the norm is 25-75 mg. Of course, this dose depends on the person's body weight and age. Larger doses are used for diseases during intensive treatment with the drug.

How much can be taken per day?

How much vitamin C is needed to achieve “tissue saturation” is a complex issue, since different organs contain and store different levels of it.

Adrenals, eyeball, prostate and the brain contain very high concentrations vitamin C in blood plasma, with tissues in which analysis is carried out - less. Because different tissues can metabolize vitamin C differently, it can be argued that blood levels of vitamin C alone cannot provide information about its presence elsewhere in the body.

In the table of the recommendations of the American Office for sanitary supervision of quality food products and Medicines (FDA) for the required daily amount of vitamin C to maintain health and prevent its deficiency:

This is not the only authoritative opinion about the required daily amount of vitamin C, but one of the most common. Some scientists and other organizations talk about numbers in the hundreds (namely, 400 mg per day) for healthy adults, or even 1000 mg per day, divided into 2 doses.

But these recommendations are not intended for athletes. It is widely believed that people with high physical activity clearly need more vitamin C. It is estimated that they need between 500 and 3000 mg of this vitamin per day, depending on their activity. Although there is unequivocal scientific evidence for the benefits of supplementation high doses ascorbic acid for athletes does not exist. Over the past decades, a lot of research has been done on this subject, but the results vary greatly, not only from neutral to positive, but there are even negative ones. Ultimately, it was accepted because genetic predisposition, rigid physical training And psychological factors play essential role in determining performance, and because any potential difference in achievement would be small, it is almost impossible to obtain scientific data on the positive effect of a particular nutrient.

special instructions

Wikipedia states that vitamin C (L-ascorbic acid) is related to glucose organic compound. Its benefits for the human body are enormous - the vitamin performs the function of a coenzyme of a number of metabolic processes, an antioxidant and a reducing agent.

According to the International Pharmacopoeia, the substance has the form of a crystalline powder, almost white or white color with a sour taste. Easily soluble in water, soluble in ethanol (about 750 g/l) TS, practically insoluble in other organic solvents Practically insoluble powder. Belongs to the category of antiscorbutic drugs.

Vitamin C in solution is quickly destroyed by air; even in a light-protected place, it is gradually destroyed in a humid atmosphere. The rate of destruction increases with increasing temperature.

Ascorbic acid is present in all tissues of higher plants and animals. Man, unlike most animals, in the process of evolution, due to mutation, has lost the ability to independently synthesize vitamin C and gets it exclusively from food.

OKPD code for ascorbic acid ( vitamin C ) - 24.41.51.180. For Food Industry the substance is obtained in accordance with GOST 4815-76.

Quantification of a substance

Methods for the quantitative determination of A.k. based on its pronounced restorative properties.

The simplest, most objective and accurate method is the method of determination based on the ability of A. to. reduce ferric ions to ferrous ions.

The amount of Fe2+ ions formed is equimolar to the amount of A.c. in the analyzed sample (the minimum amount of A.K. in the sample is 10 nmol) and is determined by a color reaction with potassium ferricyanide.

What is ascorbic acid for?

The substance is involved in the processes of biotransformation of other , education , as well as education and exchange And norepinephrine in the medulla adrenal glands , supplies hydrogen for the formation of nuclear DNA, reduces the body's need for B-group vitamins , increases the immunobiological resistance of the body, affects the activity leukocytes ; improving the absorption of Fe, thereby enhancing the synthesis hemoglobin and maturation erythrocytes , neutralizes toxins released by pathogenic microflora, accelerates wound healing and postoperative sutures and healing of fractures.

Ascorbic acid in urine is important indicator body health. Small amount vitamin C in urine may indicate a malfunction of the internal organs or the development tumor process. An increased concentration of ascorbic acid can signal an imbalance in the diet and the likelihood of kidney stones.

According to FDA classification, injection forms ascorbic acid belong to group C on a scale of possible risks to the fetus. The introduction of the solution can be prescribed to a pregnant woman only in case of emergency.

The use of high doses vitamin C for intravenous administration during pregnancy may cause miscarriage.

The minimum requirement during breastfeeding is 0.08 g / day. Theoretically, there are certain risks for the child if a nursing woman uses too high doses vitamin C .

When scientists discovered ascorbic acid in the twenties of the last century, they had high hopes for the compound. And they weren't wrong. Vitamin C has brought a lot to mankind useful action. And at the same time, almost no one guessed what an overdose threatened.

After much research, it became clear that ascorbic acid is beneficial and harmful to people at the same time. Let's find out what's what.

What is harmful ascorbic acid

Yes, that's what we used to call flat white tablets or round yellow dragees. Remember how desirable they were in childhood. And, having found the treasured bubble at home, who refused to gobble up several things at once? So how could we hurt ourselves?

Ascorbic acid itself is harmless. Its overdose brings unpleasant consequences. And only when using a synthetic product (injections or tablets). Excess vitamin found in fruits and vegetables is almost completely excreted by the body.

So, the harm of ascorbic acid:

1. It greatly increases blood clotting. Therefore, there is a high risk of blockage of all vessels with large and small blood clots. Who has not heard the terrible word blood clot?
2. Excess ascorbic acid causes severe pain in the stomach. There may be heartburn, pain, nausea. Because acid quickly corrodes the walls of the stomach.
3. Promotes the formation of sand and stones in the kidneys. This is with regular overdose.
4. The work of the pancreas is disrupted.
5. An excess of ascorbic acid disrupts the metabolism in pregnant women. And this is fraught backfire for the future child. He may already be born with allergies.
6. An allergic reaction may occur.

Who benefits from ascorbic acid

However, despite all the unpleasant moments described above, beneficial features ascorbics are simply invaluable. Naturally, only a qualified specialist can accurately prescribe the dosage necessary for the correct effect.

So, the benefits of ascorbic acid:

1. Recovery. Vitamin C takes an active part in the synthesis of collagen fibers. Thanks to him, cuts and wounds heal faster. Bones grow together much better if you take ascorbic acid.
2. Hematopoiesis. No, of course not directly. But helping the absorption of iron in the body, ascorbic acid is indirectly related to the synthesis of hemoglobin.
3. Immunity boost. This is due to the fact that ascorbic acid helps the body produce antibodies. Therefore, vitamin C is the first remedy for flu and colds.
4. Participation in metabolism. Ascorbic acid enhances the action of essential vitamins (A, E), which allows you to bring the metabolism to an almost ideal state.
5. Vessel cleansing. Recently, everyone has known terrible cholesterol. But for those who like to indulge in ascorbic acid, he is not afraid. Vitamin C significantly strengthens the walls of blood vessels, making them strong and elastic. And, like a stiff brush, it cleans all the plaques and blockages from the cardiovascular system.
6. Help with poisoning. Ascorbic acid has the ability to bind and remove free radicals from the body and heavy metals. Therefore, it is often prescribed for many types of food poisoning.

And yet, oddly enough, without ascorbic acid, all cartilage in the body becomes brittle and crumbling. Remember what old heavy smokers look like. They have a haggard appearance, plus they are very difficult to move around.

This is because one smoked cigarette neutralizes about 25 mg of vitamin C in the human body. And without it, normal absorption of other vitamins and good job cartilaginous body of the joints.

As you can see, the benefits of ascorbic acid are incomparably great in some cases. And the harm is often obtained only from excessive use.

How to understand that there is not enough vitamin C
