Many people take vitamins as dietary supplements for a variety of reasons, most often due to nutritional deficiencies. Some do it on a doctor's prescription, and others on their own. Vitamins are important for a number of processes in the body, but they are not harmless. If they are overdone, they can cause some conditions, even he alth problems.
What happens in the body if you take too many vitamins?
Vitamin A in large doses can cause dizziness
Vitamin A is a fat-soluble vitamin that is extremely important for he althy cell growth and reproductive he alth. It has powerful antioxidant properties and is important for the synthesis of hormones and neurotransmitters.

Long-term intake of high doses of vitamin A can lead to dry and scaly skin, joint pain, bone pain, headache, diarrhea, thinning of the bones, liver damage.
Too much vitamin C can cause kidney stones
Most people mistakenly think that vitamin C is harmless. This is not so. Like any vitamin, it can be overdone, and this can have its consequences. High amounts of vitamin C may be associated with an increased risk of kidney stones, according to WebMD. Ascorbic acid can cause more stomach problems, from cramps and pain to heartburn, nausea and vomiting.
Vitamin D can reduce bone density
Calcium is needed for normal bone formation and density. Calcium is absorbed in the presence of vitamin D. Most people suffer from a mild or moderate deficiency of vitamin D. Therefore, it is necessary to obtain it through dietary supplements. Paradoxically, large doses of vitamin D have the exact opposite effect – they increase blood calcium levels, which means bones become more fragile, brittle and lose their density. Therefore, if you are taking a vitamin D supplement, it is very important to monitor your blood levels to avoid overdosing.
