With the advent of the virus they wrote not one dozen posts and articles with near-scientific, but unproved methods to combat the disease. For example, it was believed that, for example, that a double dose of vitamin C and D with the manifestation of the first symptoms weakens the negative effect of the virus on health. Although the instructions for safe dosing are indicated on most bottles with additives, it is usually customary to take more recommended. Consumers are falling asleep with information on health, which states that the reception of high doses of certain vitamins can benefit their health in many ways. However, the reception of too much some nutrients can be dangerous. This article discusses the safety of vitamins, as well as side effects and potential risks associated with the use of high doses.

Fat soluble and water-soluble vitamins
13 known vitamins are divided into 2 categories - fat soluble and water-soluble.
Water soluble vitamins:
Vitamin B1 (thiamine)
Vitamin B2 (Riboflavin)
Vitamin B3 (niacin)
Vitamin B5 (Pantothenic Acid)
Vitamin B6 (pyridoxin)
Vitamin B7 (Biotin)
Vitamin B9 (folic acid)
Vitamin B12 (Kobalammin)
Since water-soluble vitamins do not accumulate, but are removed with urine, they can with a smaller probability can cause problems even when taking high doses. However, the reception of the megadosis of some water-soluble vitamins can lead to potentially dangerous side effects. For example, the reception of very high doses of vitamin B6 can over time to lead to potentially irreversible damage to nerves, while the reception of a large amount of niacin is usually more than 2 grams per day - may cause damage to the liver.
Fat-soluble vitamins:
Vitamin A
Vitamin D
Vitamin E.
Vitamin K.
Considering that fat-soluble vitamins can accumulate in the body, these nutrients are more toxic than water-soluble vitamins. In rare cases, the reception of too much vitamins A, D or E can lead to potentially dangerous side effects. On the other hand, the reception of high doses of non-secantic vitamin K seems relatively harmless, so the upper level of consumption is not installed for this nutrient. Upper consumption levels are set to designate the maximum nutrient dose, which is unlikely to damage almost all people in the overall population.
Potential risks of reception of too much vitamins
With natural use with food, these nutrients are hardly harmful, even if they are consumed in large quantities. However, if you take concentrated doses in the form of additives, it is easy to take too much, and this can lead to negative health effects.
Side effects of excessive consumption of water-soluble vitamins
When taking abundance, some water-soluble vitamins can cause side effects, some of which can be dangerous. However, as well as vitamin K, some water-soluble vitamins do not have observed toxicity and, therefore, do not have the established norm. These vitamins include vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B5 (pantothenic acid), vitamin B7 (biotin) and vitamin B12 (kobalammin). It is important to note that, although these vitamins do not have noticeable toxicity, some of them can interact with drugs and influence the results of blood test results. Therefore, caution should be taken with all food additives.
The following water-soluble vitamins have installed ULs, as they can cause side effects when receiving high doses:
Vitamin C. Despite the fact that vitamin C is relatively low toxic, high doses of it can cause gastrointestinal disorders, including diarrhea, convulsions, nausea and vomiting. Migraine may occur with a dose of 6 grams per day.
Vitamin B3 (niacin). When applying in the form of nicotine acid, niacin can cause high blood pressure, abdominal pain, violation of vision and liver damage when used in high doses - 1-3 grams per day.
Vitamin B6 (pyridoxine). Long-term excessive consumption B6 can cause serious neurological symptoms, skin lesions, light sensitivity, nausea and heartburn, while some of these symptoms occur when receiving 1-6 grams per day.
Vitamin B9 (folic acid). Reception of too much folic acid or folic acid in the form of additives may affect the mental function, adversely affect the immune system and disguise the potentially serious shortage of vitamin B12.

Please note that these are side effects that may arise in healthy people when taking large doses of these vitamins. People with diseases may experience even more serious reactions to the reception of too much vitamins. For example, although vitamin C is unlikely to cause toxicity in healthy people, it can damage the tissues and fatal heart anomalies in people with hemochromatosis, irrigation of the accumulation of iron.
Side effects associated with excessive consumption of fat-soluble vitamins
Since fat-soluble vitamins can accumulate in your body tissues, they can cause much greater harm when taking high doses, especially for a long time. In addition to vitamin K, which has a low toxicity potential, the remaining three fat-soluble vitamins have an established UL due to their ability to cause harm in high doses. Here are some side effects associated with excessive consumption of fat-soluble vitamins:
Vitamin A. Although the toxicity of vitamin A or hypervitamin can occur as a result of eating foods rich in vitamin A, it is mainly due to additives. Symptoms include nausea, an increase in intracranial pressure, to whom even death.
Vitamin D. Toxicness from taking high doses of vitamin D additives can lead to dangerous symptoms, including weight loss, loss of appetite and irregular heartbeat. It can also increase the level of calcium in the blood, which may result in damage to organs.
Vitamin E. High doses of vitamin E can disrupt blood coagulation, cause bleeding and lead to hemorrhagic stroke.
Although vitamin K has low toxicity potential, it can interact with some drugs, such as warfarin and antibiotics.
Be careful! Before taking vitamins, hand over blood test in the direction of the doctor and come to a doctor for consultation.
