Question

Which vitamins can be toxic when consumed in excess?

Answer 1

Vitamins are a category of critical nutrients that are necessary for maintaining good health. It's critical to get the appropriate levels to keep your brain, bones, skin, and blood in good shape. Several vitamins also aid in the digestion of meals. The body does not generate many vitamins, thus they must be supplied from food or vitamin supplements.

Complete answer:
The fundamental distinction that affects whether a vitamin is fat-soluble or water-soluble is whether it is fat-soluble or water-soluble. Water-soluble vitamins are utilised by the body as they are digested and are not normally absorbed for a long time in any human tissues.
Vitamins A, D, E, and K are all necessary for good health. These four are fat-soluble, which means the body may retain them for lengthy periods of time in fat deposits.
When consumed in moderate-to-extreme levels, fat-soluble vitamins are swiftly absorbed by the body and might cause immediate health problems.
Because fat-soluble vitamins are retained in the body rather than eliminated in the urine, they are more hazardous when consumed in high quantities. Overdosing on vitamins can cause the following symptoms and diseases:
Vitamin A – Hair loss, blurred vision, and liver disease are all symptoms of liver impairment.
Vitamin B – nerve damage
Vitamin B – jaundice, nausea
Vitamin D – muscular weakness, irregular heart rhythm

Note:
Vitamin poisoning is mostly caused by over ingestion of particular vitamins. A few vitamins are required in small amounts, and their overconsumption causes vitamin toxicity. As a result, it is preferable to have a sufficient number of vitamins in our regular diet.
Fat-soluble vitamins are usually stored in the body and are more harmful than water-soluble vitamins. Vitamin A toxicity, for example, causes headaches, partial hair loss, coarse hair, and dry skin.
