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.
