Vitamins are traditionally considered something beneficial and vital. They are available over the counter, and people often take them for prevention even if they have no ailments. What is wrong with vitamin tests and who really needs them Signs of Hypervitaminosis Vitamin A An excess can result from consuming large doses of supplements or a large amount of foods rich in this substance (such as animal liver). Acute manifestations include headache, nausea, vomiting, drowsiness, vision problems, and seizures. With prolonged accumulation, dry skin, hair loss, cracked lips, aching bones and joints, and headaches are possible. Vitamin D Its excess leads to calcium deposition in tissues and blood vessels, which can cause kidney stones, heart rhythm disturbances, and bone problems. General lethargy, nervousness, apathy, drowsiness, loss of appetite, nausea, vomiting, diarrhea or constipation, and dry, itchy skin also occur. Vitamin E In large quantities, it negatively affects the immune system and blood clotting, increasing the likelihood of bleeding. More details Vitamin C Frequent consumption of more than 1–5 g causes abdominal pain, diarrhea, headaches, irritability, and an increased risk of kidney stones in men. B Vitamins B6. An excess leads to impaired muscle control or coordination of voluntary movements (ataxia), heartburn and nausea, increased sensitivity to sunlight (photosensitivity), and numbness. The ability to feel pain or extreme temperatures is also reduced. B3. Overdose manifests as skin redness, impaired liver function, rapid heartbeat, and upper abdominal pain. Redness of the face, neck, and hands, a feeling of heat, and itching may be observed. Elderly people should be particularly cautious with vitamin supplements. With age, the processes of absorption, breakdown, and excretion of components from the body can change, so a standard dose of a vitamin in an elderly person can result in a higher substance level in the blood. For example, taking excessively large doses of vitamin D can provoke a decline in mental abilities. Healthy individuals who adhere to a balanced diet usually do not need to take vitamin supplements. Studies show that most people taking vitamins are already getting the required amount from food. Sources of vitamins: Vitamin A: dairy products, eggs, and fish; Vitamin B3: chicken, beef, fish; Vitamin C: fruits and vegetables; Vitamin D: the body produces it under the influence of sunlight; it is also present in fatty fish and egg yolk; Vitamin E: found in nuts, seeds, and oils. “The main rule is: vitamins should only be consumed with confirmed deficiency and as prescribed by a doctor, and daily needs are best covered by a balanced and varied diet. Vitamins are beneficial only when there is exactly the amount the body needs, and not more,” the doctor reminds us. Autumn Avitaminosis: A Diagnosis from Advertising or a Real Problem Summary An excess of vitamins, especially fat-soluble ones (A, D, E, K), can be risky. They accumulate in the body and can cause problems with the liver and kidneys and cardiovascular system disorders. In the elderly, an excess of vitamin D can lead to impaired mental function. Water-soluble vitamins (C, group B) are usually excreted, but with constant intake of large doses, they can also cause side effects. Signs of hypervitaminosis depend on the specific vitamin: nausea, lethargy, seizures, bone pain, and heart and vascular problems. The main postulate is to consume vitamins only with proven deficiency and upon a doctor’s recommendation. Daily needs are best met with a balanced diet.
