[ Properties of vitamins and their overdose
Retinol (vitamin A)
When there is not enough of this vitamin in the body, a person may have decreased salivation, as well as inflammation of the mucous membranes of the mouth. To prevent this, vitamin A is prescribed in slightly higher doses, especially for smokers, who especially suffer from dry mouth and vulnerability of the oral cavity.
If you have identified symptoms such as increased dryness of the mucous membrane, excessive hair loss, peeling nails and skin, aching bones, or toothache, this may be due to a lack of vitamin A, that is, retinol.
Ergocalciferol (vitamin D2)
It helps the body better absorb calcium, promotes the accumulation of calcium in bone tissue, and also removes harmful lead compounds from the body.
Vitamin D deficiency results in brittle bones and teeth, pale flaky skin, and dull whites of the eyes.
Excess vitamin D is a risk of developing such an unpleasant disease as osteoporosis, a decrease in the intake of minerals into the body (this vitamin in large doses inhibits their absorption), poor functioning of the heart valves, and fragility of blood vessels.
Tocopherol (vitamin E)
In case of inflammation, erosion and ulcers of gums and other tissues of the body, this vitamin is used in increased doses. But only temporarily, so that the tissues heal and the inflammation subsides.
An overdose of vitamin E can cause increased fatigue, visual impairment, and constant weakness.
Vitamin K or menaquinone
This is a vitamin that the human body itself produces. Its location is in the intestines. However, vitamin K must also be obtained from outside, using pharmaceutical preparations.
Vitamin K is prescribed for increased bleeding gums, as well as other diseases of the oral cavity. In particular, it helps well with decreased blood clotting, periodontitis and gingivitis.
Thiamine (vitamin B1)
If your body lacks vitamin B1, you may feel dry mouth, ulcers and cracks may appear in your mouth. If you see these signs, see a doctor immediately for examination and prescription of vitamin therapy in the doses you need.
If, on the contrary, you overdo it with vitamin B1, it can cause increased fatigue, drowsiness, even nausea and shortness of breath.
Vitamin B1 in doses above average is prescribed for facial nerve disease, neuritis, stomatitis, glossitis. It helps very well!
Riboflavin (vitamin B2)
If you have cracks in your lips and mouth, as well as soreness of the papillae of the tongue, you will most likely be prescribed vitamin B2, or riboflavin. Allergies to it are rare, this drug is usually well tolerated, although overdoses are dangerous due to increased fatigue and weakness.
Pyridoxine (vitamin B6)
If the body lacks this vitamin, wrinkles may appear around the eyes and mouth even at a young age. In addition, you may have anemia, diseases of the mucous membranes, periodontitis, glossitis.
Vitamin B6 is the first medicine for all these diseases.
If you overdo it with the doses, you risk increasing the level of hydrochloric acid in the stomach, as well as numbness in the arms and legs. Sometimes unexpected cramps can bother you, but this is with a very high dose of vitamin B6 administered intramuscularly.
Cyanocobalamin (vitamin B12)
This famous vitamin can help with dry mouth, gum disease, unexplained numbness and astringency of the tongue, and a change in the color of the mucous membrane to bright red.
This means that you currently lack vitamin B12 in your body. It is used to treat anemia and even radiation sickness, as well as neuralgia.
Vitamin C (folic acid)
If your body lacks this vitamin, you may suffer from gingivitis, periodontal disease, and ulcers may be found in your mouth. All of this is a lack of vitamin C.
Overdose of this vitamin leads to malfunctions of the immune system, a decrease in the level of vitamin B12 in the blood. And this is anemia and increased fatigue, metabolic disorders. Therefore, it is necessary to carefully observe the dosage of vitamins.
Nicotinic acid (vitamin PP)
If you have a lack of vitamin PP in your body, it can be visible even externally. The oral cavity changes color to bright red, the tongue also becomes a rich red color, swells, becomes flaccid and swells. Headache and lethargy are also possible.
A deficiency of vitamin PP leads to increased salivation with dry mouth, ulcers, discomfort on the tongue, and redness of the skin.
