An overdose of vitamin C is rare, but it can cause a lot of discomfort to a person. Many people take this substance uncontrollably, considering it safe. However, an excessive amount of vitamin adversely affects the state of the body. How to determine an overdose?
The benefits and harms of the vitamin
Vitamin C is an essential element in the human body. Unfortunately, it is not produced independently, but only comes from the outside with food and drink. The element has many beneficial effects on organs and systems.
Actions:
- Takes part in collagen synthesis, carbon exchange,
- It is necessary for normal blood formation,
- Promotes normal blood clotting,
- Reduces inflammation, promotes rapid recovery,
- Essential for gums, teeth, bones,
- Reduces the risk of developing allergic reactions,
- Helps relieve stress,
- Has a beneficial effect on the immune system,
- Essential for the absorption of other vitamins.
Lack of vitamin C leads to disruption of many body systems. If a person has bad habits, the minimum level of the element is diagnosed, therefore, an increased dosage is allowed.
However, in some cases, vitamin C can be harmful and negative. When is an element dangerous?
Occasions:
- The presence of cataracts
- High blood pressure,
- Diabetes,
- Tendency to form blood clots
- Kidney disease
- Salt diet.
In these situations, excess vitamin C can be harmful. For women during pregnancy, it is recommended to take the element after consulting a specialist in order to avoid rejection of the fetus.
The norm of vitamin "C" per day
What is the normal dosage of vitamin C in adults and children? How much element is needed for the normal functioning of the body?
On average, up to 80 mg of the substance is allowed per day for adults and up to 40 mg for children. The maximum value should not exceed 90 mg per day. However, the amount of the vitamin is allowed to change in some special cases.
During pregnancy, it is allowed to consume up to 100 mg of the substance per day, and during lactation - up to 120 mg. The dosage depends on many factors - ecology, bad habits, place of work, age, gender.
It is required to take preparations with vitamin C with meals. The dosage should be changed gradually, the therapeutic amount in some cases can reach 1500 mg. Maximum - intramuscular injection of 10 ml in the form of a solution.
Reception for a couple of days once more than 30 g of the substance can lead to a serious overdose and death.
When is an overdose possible?
Why is it possible to develop an overdose? What can provoke intoxication and cause discomfort? In most cases, an excess of vitamin C does not cause much harm, however, in the presence of some factors, the appearance of an overdose and negative symptoms is not excluded.
Factors:
- Lack of control when taking ascorbic acid, especially in children,
- Simultaneous use of foods with a high content of the element and vitamin complexes,
- A single dose of an increased dosage.
With a systematic intake of more than one gram per day, the appearance of hypervitaminosis and overdose is possible.
Symptoms of an excess of vitamin c
What are the symptoms of excess vitamin C in the body? How is an overdose of an element characterized? With prolonged use of an increased dosage in adults, various changes in the functioning of the body are diagnosed.
Signs:
- Pain in the head
- High blood pressure,
- Unpleasant sensations in the kidneys
- Irritation of the urinary tract mucosa, manifested by signs of cystitis,
- Allergic rashes on the skin,

In case of an overdose of such a substance in the body, the presence of various disorders of the functioning of organs and systems is noted. The formation of stones is possible in the kidneys and gallbladder, there are malfunctions of the heart system.
With prolonged use of an increased dosage, the development of irreversible changes in the work of the kidneys, adrenal glands, and pancreas is not excluded. If signs of an overdose of vitamin C appear, you need to contact a medical institution.
Methods and methods of treatment for overdose
How is an overdose of ascorbic acid treated? The victim needs to be given more water to drink. Vitamin C dissolves well, therefore, when fluid is consumed, its concentration will decrease and the excess will be excreted by the kidneys.
When taking a large volume of a substance at a time and diagnosing an overdose, it is required to provide the victim with first aid.
- Gastric lavage is performed with a large volume of water,
- An overdose victim is given activated charcoal, it will help to quickly remove toxic substances.
- It is recommended that the patient give more water to drink in case of an overdose, such an action will speed up the process of removing excess element.
The method of further treatment of an overdose after first aid is chosen by a medical professional. In case of mild poisoning, therapy at home is allowed, a severe degree requires careful treatment in a medical institution. The actions carried out in the hospital are aimed at reducing the level of the vitamin in the body and improving the functioning of internal organs.
Consequences and prevention
Vitamin C poisoning is rare, but it can have quite serious consequences and complications. What can cause such an overdose?
Complications:
- Diabetes,
- Diseases of the stomach and intestines,
- Weakness in the body

Crystal Eyes is the best way to restore vision at any age.
Despite the fact that ascorbic acid is considered safe, it should not be overused. Preventive measures will help avoid overdose and unpleasant consequences.
Measures:
- Do not take more than the prescribed dosage,
- Store vitamin C out of the reach of children, monitor the number of tablets eaten,

Vitamin C plays an important role in the body, participating in many life support processes. It is necessary for the normal functioning of the blood supply system, helps to strengthen the immune system. In women, this substance affects the nature of the course of menstruation. It is taken for medicinal as well as prophylactic purposes to enhance the body's resistance to adverse factors. However, like any other medicine, ascorbic acid cannot be consumed uncontrollably. A significant excess of the dose of vitamin C can lead to poisoning.
The role of vitamin C is as follows:
- It actively participates in the creation of immune cells necessary to suppress the harmful effects of viruses and bacteria.
- It is an antioxidant, suppresses the action of free radicals. Acting as a catalyst for redox reactions, vitamin C protects cells from "overoxidation" leading to their destruction and malignant transformation.
- It has a calming effect on the nervous system, improves brain function.
- Improves vision.
- Helps strengthen the walls of blood vessels, prevents bleeding and inflammation of the gums (scurvy).
- By accelerating protein and fat metabolism, it maintains skin and hair nutrition.
- Increases resistance to various allergens.
- Improves the absorption of iron and calcium, as well as the elimination of harmful compounds of copper, lead and mercury from the body.
- Prevents the deposition of cholesterol in the blood vessels.
Vitamin C is able to increase blood clotting, so it is prescribed for women suffering from uterine bleeding.
The body's daily need for ascorbic acid
Ascorbic acid is highly soluble in water. Entering the body, it is partially consumed, satisfying the needs of the body, partially deposited in the tissues "in reserve", the rest of the substance is excreted in the urine. Improper intake of vitamin C is dangerous for overdose and the occurrence of harmful consequences.
The body's need for this substance depends on the woman's age, the nature of the loads, the presence or absence of bad habits, the physiological state, and climatic conditions.
The body's need for vitamin C (table)
When the need for vitamin C rises
Vitamin C is not produced in the body. Its stock must be constantly replenished. Daily consumption of fresh vegetables and fruits may well satisfy the daily requirement of a healthy person's body for this substance, even allowing it to accumulate in a small excess. At those moments when the load on the body increases, the consumption of ascorbic acid increases. Its intake with food is not enough, an additional intake of a synthetic drug in the form of pills, tablets or injections is required.
This happens in the following cases:
- during and after illness, as well as during epidemics of viral diseases;
- with intense physical and mental activity;
- after poisoning with toxic substances;
- when replenishing hypovitaminosis in the winter-spring period;
- in an unfavorable climate;
- during puberty, if a girl develops anemia due to the appearance of juvenile bleeding;
- with uterine bleeding in adult women;
- in old age, when the absorption of useful food elements by the body worsens;
- when using hormonal contraceptives, which cause a decrease in the concentration of ascorbic acid in the blood;
- during pregnancy and breastfeeding;
- in the presence of bad habits (smokers and alcohol abusers have no supply of vitamin C).
Recommendation: It is necessary to eat so that a sufficiently high dose of vitamin C is constantly maintained in the body during the day. It is useful to satisfy the daily requirement not at one time, but in several doses, especially with the additional use of synthetic vitamin.
As a rule, taking the drug in increased doses is prescribed for colds, inflammatory and infectious diseases, in the treatment of cancer. The use of this substance (in combination with hormonal drugs) is recommended for women who have delayed menstruation. The dose of vitamin C is increased during pregnancy planning.
Contraindications and restrictions
Contraindications to the use of synthetic vitamin C is only the presence of an allergy to ascorbic acid.
Those patients in whom an overdose of vitamin C is of particular danger should be prescribed with caution, in individual doses, taking into account the possible side effects of the drugs. This category includes pregnant women, as well as people suffering from hypertension, diseases of the kidneys, digestive organs, liver, diabetes mellitus, vascular and blood diseases, cataracts.
Consequences of hypervitaminosis
An overdose occurs when more than 1 g of vitamin C is systematically consumed. At the same time, the excess of the substance does not have time to be excreted from the body in the urine, it accumulates in an amount that significantly exceeds the required supply. Another factor contributing to the oversaturation of the body is its accidental use in a dose that is many times higher than the maximum allowable (2.5 mg / kg of body weight).
An overdose of ascorbic acid leads to the development of an allergy to it, a change in the composition of the blood (destruction of leukocytes). One of the most dangerous consequences of poisoning is vascular thrombosis. Excessive use aggravates the course of neurological diseases, as well as rheumatism, heart disease.
With an excess of vitamin C, the acidity of the gastric environment increases, therefore it is not taken together with drugs that irritate the mucous membranes (such as aspirin, indomethacin, reserpine). Acid taken in excess can cause exacerbation of gastritis, stomach ulcers or pancreatic ulcers.
This substance increases the acidity of urine. Its overdose accelerates the formation of kidney and ureteral stones. Ascorbic acid, entering the body in excess, is capable of destroying vitamin B12. In turn, the lack of this substance in the body leads to the appearance of anemia and neurological disorders (headaches, insomnia).
Vitamin C, entering the body in large doses, interferes with the production of insulin, so its excessive intake is unacceptable in diabetes mellitus.
Warning: An overdose of vitamin C is undesirable for those who drive vehicles or perform work that requires precise manipulation, since with an excess of it in the body, visual acuity decreases and coordination of movements is impaired.
Overdose symptoms
Due to poisoning due to an overdose of ascorbic acid, as well as irritation of the digestive tract and the appearance of anemia, the following symptoms occur:
- weakness;
- nausea, vomiting, dizziness;
- heartburn, abdominal pain, indigestion;
- allergic skin rash;
- headache;
- deterioration of vision;
- rapid onset of muscle fatigue;
- increased irritability;
- insomnia;
- increased urination;
- decreased blood sugar concentration.

Consequences of a vitamin overdose during pregnancy
During this period, vitamin C is necessary for normal metabolism, weakening the manifestations of early toxicosis in a pregnant woman, protecting teeth from decay, maintaining a normal blood composition, and preventing bleeding during childbirth. If a woman did not have hypovitaminosis before pregnancy, then the body's need for ascorbic acid may well be satisfied by the consumption of foods of natural origin (for example, 2 oranges a day).
Synthetic vitamin preparations during pregnancy can be taken only as directed by a doctor, since even a small excess of ascorbic acid can lead to impaired fetal development. Enhanced production of enzymes and excessive acceleration of metabolism in the body contribute to the development of vitamin deficiency in the mother and fetus. After birth, the baby develops a disease called "rebound scurvy."
The use of high doses of vitamin C by a pregnant woman leads to an addictive effect in the newborn. His body will feel a lack of this substance, which will cause a delay in development.
The intake of ascorbic acid in increased quantities provokes a miscarriage (this, in particular, is the basis for the popular method of terminating an unwanted pregnancy).

Reasons for exceeding the norm
The occurrence of an overdose of vitamin C in the body is possible when, for example, it is used in high doses to prevent colds and viral diseases. Some people mistakenly believe that the more it is taken, the less likely it is to get sick.
The reason for exceeding the norm is the increased intake of pills simultaneously with the use of foods rich in this substance. In some cases, an overdose occurs due to non-compliance with the doctor's recommendations on the use of a synthetic vitamin preparation for medicinal purposes.
Especially often oversaturation occurs in those who consume the vitamin in the form of "harmless" dragees, reminiscent of candy in taste.
How to deal with symptoms of an overdose
To avoid overdose, the following rules must be observed:
- Do not use synthetic drugs if the diet contains enough plant foods, especially raw vegetables, herbs, fruits (this vitamin is also found in animal by-products, but since they are boiled or fried, the vitamin in them is almost completely destroyed).
- Do not use vitamin C uncontrollably, "just in case."
- Remember that to meet the needs of an adult's body, it is enough to take 1 tablet of vitamin C per day. When using it in other forms, it is necessary to observe the doses indicated in the instructions.
When symptoms of an overdose appear, first of all, it is necessary to stop taking the synthetic drug and limit the use of foods containing it in large quantities (such as spinach, tomatoes, citrus fruits, salad greens, green peas, black currants), as well as freshly squeezed juices , rosehip infusion. Food should be high-calorie in order to increase the consumption of ascorbic acid for its processing.
It is necessary to drink plenty of water to stimulate the excretion of this substance in the urine. With a significant deterioration in well-being after taking a large dose of vitamin, it is necessary to immediately induce vomiting and make a gastric lavage, as well as take adsorbing agents such as activated carbon or smecta.
The norm is considered to be up to 90 mg for an adult and up to 30 mg for a child per day.... This is usually written on the prescription for the drug.
In practical terms, this means that:
- infants who are breastfed do not need additional intake of the substance;
- the daily dose for children under 3 years old is 15 mg;
- preschoolers will need 25 mg;
- will be most effectively protected from colds when consumed 45 mg per day;
- female adolescents - 65 mg, male - 75 mg;
- the norm for an adult woman is 75 mg. (during lactation + 10 mg, + 30 mg);
- the norm is 90 mg.
Smokers can safely increase their dose of ascorbic acid by 35 mg every day.
Also the need for vitamin C increases during physical activity (+30 mg). Do not forget that the daily dose includes not only the drug itself, but also all the ascorbic acid that is available to the body. Diet is the main medicine in this matter.
Its role in the body
Vitamin C affects:
- protection against free radicals;
- the course of the lion's share of biochemical processes (synthesis of hemoglobin, collagen, etc.);
- digestibility,;
- the course of many diseases and special conditions (ulcer, infectious diseases, neurodermatitis, increased physical activity, lactation period in women, etc.).
With its catastrophic deficiency, a person falls ill with scurvy.... An overdose of vitamin C as a reverse condition is also unpleasant, and even dangerous. A one-time intake of 30 g of the substance (without its excretion, which is possible only with complete disruption of the kidneys), leads to death.
Oversupply: symptoms and signs
When taking large amounts of vitamin C orally for a long period of time a person may notice the following symptoms of an overdose:
- dizziness;
- digestive problems: heartburn, nausea and vomiting;
- sleep problems;
- fatigue;
- itchy skin, rash;
- in women - menstrual irregularities.
Particular attention to their condition and diet during the regular intake of ascorbic acid should also be taken by people who suffer from kidney disease.
The consequences of exceeding the dosage
Since ascorbic acid affects the formation of hemoglobin and is excreted by the kidneys, then due to exceeding its concentration, there may be:
- various failures in the functionality of the kidneys and pancreas;
- gastritis and ulcers (while taking aspirin);
- allergic reactions;
- nervous irritability (the effect may be delayed for months or even years);
- complications with thrombophlebitis;
- the threat of miscarriage during pregnancy;
- increased blood pressure.
What threatens children?
Psychologists who have been studying nervous reactions in childhood and adolescence for a long time argue that "shock" doses of ascorbic acid, consumed from early childhood, in addition to benefits for immunity can harm the nervous system.
For this reason, one should refrain from pampering children, limiting consumption to 30 mg. Moreover, both pills and foods that the offspring eat should be taken into account.
For example, in the summer, while collecting black currants or when taking rosehip decoctions, ascorbic acid in pharmacological form should not be consumed at all.
How is it treated?
What to do in case of an overdose of ascorbic acid? Excess substance is excreted from the body on its own, through additional stress on the kidneys.
For a healthy body, it will be enough just to follow the drinking regime (drinking at least three liters of warm water per day) and eat in a balanced way.
If possible, exclude from the diet foods in which the concentration of vitamin C is increased. These include rose hips, black currants, bell peppers, dill, etc. People with kidney disease should immediately contact their doctor and report the symptoms.
Generally, overdose of vitamin C is a common occurrence, for most people passing is not noticeable and without symptoms... But experts say that the abuse of sweet balls can not only aggravate existing diseases, but also affect human health in later life.

Content
Ascorbic acid (or vitamin C) is necessary for our body because it participates in many processes and supports our immunity. It affects the state of the circulatory system, helps the body to maintain its tone and slows down the aging process. But with the thoughtless use of ascorbic acid, an overdose of vitamin C can occur. As a result, the properties of this substance will cease to benefit the body, but will turn into harm.
Can there be an overdose of vitamin C?
We are used to perceiving ascorbic acid as an absolutely harmless element we need. It is easy to buy at the pharmacy. Acid is a water-soluble substance: excess vitamin C is excreted from the body along with urine. But with a systematic excess of the daily requirement, this process does not have time to occur, then an overdose becomes possible. This happens in specific cases:
- In winter or early spring, when the intake of ascorbic acid is dictated by the prevention of viral diseases and seasonal vitamin deficiency.
- During illness, when the norms of the daily needs of the body are not observed.
- With the joint intake of vitamin C and multivitamins.
- In cases where a person's diet is rich in foods with a high acid content, but he takes synthetic substances.
It's important to keep track of your diet. To maintain health and immunity, you must eat foods rich in vitamin C:
- rosehip;
- bell pepper;
- sea \u200b\u200bbuckthorn;
- kiwi;
- black currant;
- brussels sprouts;
- viburnum berries;
- orange;
- grapefruit;
- lemon.
The average daily requirement of a healthy adult for ascorbic acid does not exceed 100 mg. During the period of illness or vitamin deficiency, this indicator increases significantly, up to about a thousand mg per day. At such a time, it is not enough for a person to simply follow a correct, healthy diet. There is an urgent need for additional measures.
However, here you should take into account your gender, age, nature of the disease. The human body changes greatly throughout life. To take vitamin C correctly, you need to know the purpose of prescribing the drug, to analyze your own health. All this information can be obtained from the attending physician by contacting him for advice or by watching the following video.
For a long time, medicine has not recognized that an overdose of vitamin C is dangerous for humans. They treated ascorbic acid somewhat carelessly, took it uncontrollably, adjusting the rate, according to their own considerations about it. So, in childhood, many of us ate yellow pills like candy. Recent research has refuted this theory. Now we know how to recognize a threat.
Overdose symptoms and signs
The increased content of ascorbic acid in the human body often leads to negative consequences. While taking vitamins, you need to pay special attention to your well-being, analyze it. The following signs may indicate an overdose:
- nausea;
- dizziness;
- insomnia;
- persistent vomiting;
- spasmodic pain;
- stomach upset;
- heartburn;
- rashes on the skin.
The appearance of any of these symptoms can be a signal of an overdose. In this case, you must immediately stop taking medications and consult a doctor. But all these signs can also be the result of various diseases or arise for other reasons. Sometimes it is difficult to pay attention to them and associate ailments with an increased content of vitamin C in the body.
Why is excessive consumption of vitamin C dangerous?
Uncontrolled intake of synthetic vitamin C, like other substances, causes toxicosis, disrupts vital processes, and leads to the development of serious diseases. For many people, this element is an allergen: a reaction to an overdose manifests itself as irritation of the skin, the appearance of spots and foci of inflammation, and causes disruption of the kidneys and gallbladder.
Do not combine the intake of ascorbic acid with aspirin or drugs that contain aluminum. Aspirin will promote the rapid elimination of vitamin C from the body, while aluminum, on the contrary, will lead to its accelerated absorption and possible toxicosis. Pregnant women and children need to take ascorbic acid carefully, because for them an overdose when taking vitamin C is especially dangerous.
During pregnancy
During the period of bearing a child, a woman is responsible not only for herself. The health of the unborn baby depends on how the expectant mother will eat and take care of herself. Previously, medicine did not find a connection between congenital diseases, defects in infants and an excess of vitamin C. But modern studies have shown that excessive use of ascorbic acid during pregnancy can harm the fetus in the form of:
- scurvy;
- avitaminosis from the first days after birth;
- pathologies;
- cleft lip;
- heart disease.
An overdose of vitamin C in some cases leads to miscarriage. To avoid this condition and the terrible consequences, you need to know and take into account the daily rate of ascorbic acid. For a pregnant woman, this is approximately 80-90 mg, but only the attending physician can indicate the exact value. It is important to get accurate advice from him and follow them.
In children
Children are especially sensitive to any changes in the body. This is due to the fact that their defense mechanisms are not yet fully formed. The child's body is constantly growing, changing, and with it his need for various substances increases. An excess of ascorbic acid often causes the development of diabetes mellitus and negatively affects the work of other organs.
The daily requirement of children for vitamin C depends on age:
- For children from one to 3 years old - 15 mg.
- At the age of three to eight - 25 mg.
- For children 8 - 12 years old - 45 mg.
In such quantities, ascorbic acid is most easily obtained from food. To do this, you should develop a balanced diet and adhere to it. There must be special reasons for taking special drugs and exceeding this norm. For example, viral diseases. Ascorbic acid should be given to children only as directed by the attending physician.
The consequences of exceeding the dose
Periodic excess of the body's daily requirement for vitamin C is dangerous for humans, as it can have a variety of consequences. Some may appear only after a while, and at the initial stage they may be invisible. In any case, an overdose of ascorbic acid will negatively affect your health. A significant, systemic excess of the dose causes such diseases as:
- hyperglycemia or excessive blood sugar;
- the development of stones inside the kidneys;
- diabetes;
- dysfunction of the adrenal glands;
- leukopenia or lack of white cells.
This does not mean that it is necessary to stop taking ascorbic acid altogether. It is important to observe the dosage, and increase it only on the recommendation of a doctor. A short-term excess of the norm during periods of illness, stress is not dangerous, and the excess is easily removed with a large amount of fluid. Avoid the constant use of high doses of vitamin C, which can be harmful to health.
