With the beginning of autumn and winter people become weaker, appear stresses, depressions, viruses, diseases. We start taking different vitamins to help our organisms to overcome illnesses. Vitamins are like guardians for our bodies, which protect in the most difficult situations. Without proper amount of vitamins we do not feel good, we feel weakness, apathy.

Vitamin A is very important for the human body. This vitamin is important for healthy bone growth. We shouldn't forget and neglect the importance of this vitamin for eye vision and immune system. It is like a shield that protects your organism from dangerous bacteria.

That is why when fresh fruits and vegetables appear in the big amount and the price is affordable for all people we buy them to fulfill the missing vitamins in our bodies.

But even vitamins should be taken carefully. The deficiency or overdose can cause serious problems to people, starting from rash and ending, unfortunately, with death. Always consult a professional, especially if your child is weak or easily catches cold or other diseases and infections.

What are the risks for your health of overdose of vitamin A? Too much of vitamin A in your organism may lead to different vitamin A side-effects such as birth defects, osteoporosis, vitamin A toxicity and disorders of central nervous system.

The symptoms of vitamin A toxicity are headache, dizziness, vomiting, muscular incardination and blurred vision.

What are the reasons of accruing of the overdose of vitamin A? This problem may appear when you consume too much of liver. Still, this is not the only reason. Most frequently overdosing appears in cases of taking big amounts of the supplementary nutrients.

Vitamin A can be converted from provitamin A carotenoids, which are found in dark pigments of plant foods. But too many of these carotenoids can also be risky for your health. For example, overdosing of provitamin A carotenoids may turn the color of your skin to yellow. But such side-effect is not dangerous for your health.

As it has been said in the beginning, in some cases the overdose of vitamin A can be very harmful or even fatal for a person. Sometimes we are not even able to control it. For example, one amount of vitamin A can be absolutely normal for animals, while for people the same amount can cause vitamin A toxicity.

This should be really important and useful information for people who have decided to go into some polar expeditions. The livers of animals living there contain such an amount of vitamin A that could kill a person. The first case of death due to overdose of vitamin A that was documented happened with a Swiss scientist Xavier Mertz while an Antarctic Expedition in January 1913... The supplies of food were poor, but nobody wants to die; so he began to eat his sled dog's livers. The amount of vitamin A was too much for the scientist.

So remember - vitamins are good for you, but only when taken as directed.
