All About Vitamin A

Vitamin A was first discovered back in 1912, by a Polish biochemist named

Casimir Funk. He came up with the word vitamine, which was later given the name
vitamin. Funk was the first to discover vitamins as we know them today, although
vitamin A was actually the first one discovered, hence the letter “A” in the
title of the vitamin.



You can find vitamin A in natural foods such as oranges and yellow fruits. It
can also be found in vegetables as well, such as spinach and fats. When found in
vegetables, vitamin A is water soluble, coming in the form of beta carotene. The
beta carotene form of vitamin A can be eliminated from your body through natural
processes, making it an excellent way to get vitamin A.



Vitamin A is required by the body on an every day basis to maintain healthy skin
and keep your eyesight on track. There are many people who say that carrots
provide enough vitamin A to prevent you from getting night blindness. The fact
is, ancient Egyptian doctors prescribed liver in their time, which they said
contained enough vitamin A to combat night blindness. Vitamin A is also known as
an antioxidant, which makes it ideal to prevent cancer and anti aging. Along
with these benefits, it also helps with your immune system as well.



To get the proper absorption of vitamin A, you’ll need to consume fat. Those of
you who happen to be on a low fat or restricted diet, simply may not be getting
the right amounts of vitamin A from your supplements that you may think. To get
the proper absorption of vitamin A in your diet, you’ll need to consume a high
enough level of protein. Protein combines with vitamin A to make it stronger,
and help it move through your body.



On a normal day, you should be consuming around 5,000 international units (IU)
of vitamin A. Depending on your health and your age, you may need to consume
more or less. The safest form of vitamin A is beta carotene as mentioned above,
and it can be taken in much larger doses. No matter what age you may be, you can
feel safe to consume high amounts of vitamin A in the form of beta carotene.



If you don’t consume enough vitamin A in your diet, you’ll end up with a
deficiency. A deficiency is never a good thing, as it normally results in skin
problems, increased infections, and even night blindness as well. A prolonged
deficiency in vitamin A can put you at a risk for cancer as well, and you’ll
also miss out on any effects of anti aging that the vitamin might have. Although
you should begin taking it immediately if you have a deficiency, the effects
wouldn’t be the same as they would be if you stayed up to date with the right
amount on a daily basis.



On the other hand, if you are getting too much vitamin A, you’ll put yourself at
risk for pain in your joints, abdomen, and your bones. Even though too much or
not enough can cause you serious side effects, you should always get the right
amount in your diet. Vitamin A is very important, and should always be included
in your diet. You can find it in many foods, or take supplements that include
the well needed vitamin. If you are going to take supplements, you should make
sure that they provide the right amounts - with no side effects.
