The Dire Effects of Vitamin A

As a means of being aware of you
not to fall trapped to this situation of getting into mess of getting
the sickness of vitamin A deficiency best knows how to avoid that to
affect you.  Well to those of you who weren’t
that much aware of what basically Vitamin A is then, let me be your
knight shine in armor by saying that vitamin A is a compound also known
as Retina more to those who are in the medical fraternity . it is being
defined as a vitamin that is needed by the retina of the eye in the form
of a specific metabolite, the light-absorbing molecule retinal, that is
necessary for both low-light (scotopic vision) and color vision.
Vitamin A also functions in a very different role as an irreversibly
oxidized form of retinol known as retinoic acid, which is an important
hormone-like growth factor for epithelial and other cells. Well like the
headline says, my plan is to dwell more into the deficiency that can be
caused if one don’t take the required amount of foods that will ensure you don’t
get that chance of being a statistics that is being counted as those
who are suffering from that condition. The way this condition is so
endemic, Vitamin A deficiency is estimated to affect approximately one
third of children under the age of five around the world. It is
estimated to claim the lives of 670,000 children under five annually.
Approximately 250,000–500,000
children in developing countries become blind each year owing to
vitamin A deficiency, with the highest prevalence in Southeast Asia and
Africa. Vitamin A deficiency can occur as either a primary or a
secondary deficiency. A primary vitamin A deficiency occurs among
children and adults who do not consume an adequate intake of provitamin A
carotenoids from fruits and vegetables or preformed vitamin A from
animal and dairy products. Early weaning from breastmilk can also
increase the risk of vitamin A deficiency.

Secondary vitamin A deficiency is
associated with chronic malabsorption of lipids, impaired bile
production and release, and chronic exposure to oxidants, such as
cigarette smoke, and chronic alcoholism. Vitamin A is a fat soluble
vitamin and depends on micellar solubilization for dispersion into the
small intestine, which results in poor use of vitamin A from low-fat
diets. Zinc deficiency can also impair absorption, transport, and
metabolism of vitamin A because it is essential for the synthesis of the
vitamin A transport proteins and as the cofactor in conversion of
retinol to retinal. It is no wonder you find this condition in
malnourished populations, as the common low intakes of vitamin A and
zinc increase the severity of vitamin A deficiency and lead
physiological signs and symptoms of deficiency.

That
is just a stern warning and do trust that you will be able to make
conscious decisions to best approach our exclusive vitamin site of

Vitamin A Supplement Benefits

We can all benefit from the vitamin
and if we consume the right dosage then we can stay in a healthy state
and keep it that way. Vitamin A, also called retinol, helps your eyes
adjust to light changes when you come in from outside and also helps
keep your eyes, skin and mucous membranes moist. Vitamin A mostly comes
from animal foods, but some plant-based foods supply beta-carotene,
which your body then converts into Vitamin A. It also has antioxidant
properties that neutralize free radicals in the body that cause tissue
and cellular damage. Eating a normal diet of foods rich in these
vitamins won’t cause a problem. Remember, you only need small amounts of
any vitamin, so you don’t
have to overdo it because that can lead to unforeseen results. In the
case of vitamin A, overconsumption has been linked with an increased
risk of fractures in postmenopausal women. So when you supposed to take
this much you should stick to it and don’t
think otherwise, you will be saving your own life. And if you have a
chronic health condition, ask your doctor about whether your vitamin
absorption will be affected. It’s always important to consult a specialist first before taking anything that might harm you at the end, so do exactly that.

And if
you want to get the most vitamins possible from your food, refrigerate
fresh produce, and keep milk and grains away from strong light.
Vitamins are easily destroyed and washed out during food preparation
and storage. So if you take vitamin supplements, store them at room

Types of Foods that has Vitamin A

You love chewing and munching
anything that passes through your mouth and some of those foods you love
eating might have some of the most beneficial results for your
wellbeing which you would gladly love to see that taking place. Well my
initial intention roundabout here is to review about Vitamin A complex
which is hugely required in our bodies at all times because if you do
so, you will be able to keep the abreast with the ideal things that
holistically keeps you as healthy as a fiddle. Vitamin A is a generic
term for a large number of related compounds. Retinol (an alcohol) and
retinal (an aldehyde) are often referred to as preformed vitamin A.
Retinal can be converted by the body to retinoic acid, the form of
vitamin A known to affect gene transcription. Retinol, retinal, retinoic
acid, and related compounds are known as retinoid. Beta-carotene and
other carotenoids that can be converted by the body into retinol are
referred to as provitamin a carotenoids. The way it functions, this
vitamin complex it plays a vital role in the growth and repair of body
tissues, and is particularly important in maintaining good eyesight and
healthy skin, as well as aiding in bone and teeth formation. Recent
research suggests that it may also function as an anti-oxidant which its
basic function deals with the retina is located at the back of the eye. When light passes
through the lens, it is sensed by the retina and converted to a nerve
impulse for interpretation by the brain. Retinol is transported to the
retina via the circulation and accumulates in retinal pigment epithelial
cells (diagram). Here, retinol is esterified to form a retinyl ester,
which can be stored. When needed, retinyl esters are broken apart
(hydrolyzed) and isomerized to form 11-cis-retinol, which can
be oxidized to form 11-cis-retinal. 11-cis-retinal can be shuttled
across the interphotoreceptor matrix to the rod cell where it binds to a
protein called opsin to form the visual pigment, rhodopsin (also known
as visual purple). Rod cells with rhodopsin can detect very small
amounts of light, making them important for night vision.

In
terms of the foods sources, be in the know that Free retinol is not
generally found in foods. Retinyl palmitate, a precursor and storage
form of retinol, is found in foods from animals. Plants contain
carotenoids, some of which are precursors for vitamin A (e.g.,
alpha-carotene, beta-carotene, and beta-cryptoxanthin). Yellow and
orange vegetables contain significant quantities of carotenoids. Green
vegetables also contain carotenoids, though the pigment is masked by the
green pigment of chlorophyll. A number of good food sources of vitamin A
are listed in the table below along with their vitamin A content in
micrograms of retinol activity equivalents (mcg RAE). In those foods
where retinol activity comes mainly from provitamin A carotenoids, the
carotenoid content and the retinol activity equivalents are presented.

So
there you have it then guys and I kindly insist that if you would like
to pair yourself with knowledge of this kind which by the way is so in
abundance through our very own site vitamin-a.co.za to stick with this
very same site as you will just get that…which is what you have
bargained for. 

You can benefit from Vitamin A

Vitamin A is important for the immune system and it keeps skin and mucous membrane
cells healthy and when membranes are healthy they stay moist and
resistant to cell damage. Healthy cells are also resistant to cancers
and Vitamin A fights cancer by inhibiting the production of DNA in
cancerous cells. It slows down tumor growth in established cancers and
may keep leukemia cells from dividing. Blood levels of vitamin A are
often low in people with viral illnesses. After receiving additional
amounts of this vitamin, the body is able to mount its defenses, often
resulting in a quicker recovery.  Stroke victims
who have high levels of vitamin A in their systems are less likely to
die or suffer disabilities from the stroke and eating plenty of fruits
and vegetables is a good defense against
stroke and its complications. Vitamin A taken orally and applied
topically looks promising in preventing and possibly even treating skin
cancers. It may be helpful, too, in lightening liver spots, those dark
spots that often appear on aging skin. And probably what you didn’t
know was that Vitamin A derivatives are used to treat skin disorders,
Isotretinoin acne medicine is an oral medication used for severe cystic
acne. Because of the possibility of such serious side effects as liver
damage and elevated blood triglycerides, a doctor must closely monitor
treatment with this medication.

Any woman capable of becoming pregnant needs to use reliable birth control when
taking this medicine because it can cause spontaneous abortion or
serious birth defects. Pregnant women must avoid it and other sources of
high-dose vitamin A. Now that you know its
benefits and that you can benefit from it you can now take good care of
your health. Since I gave you the information that can benefit you, you
can perhaps teach others too.

And you can change your family to
follow you in your new path of changing your eating habits, you might
not see it immediately but you will see the difference at the end of the
day.

What is Vitamin A?

It is a vitamin and it is used for
treating vitamin A deficiency, it is also used to reduce complications
of diseases such as malaria, HIV, measles, and diarrhea in children with
vitamin A deficiency. And it can be found in many fruits, vegetables,
eggs, whole milk, butter, fortified margarine, meat, and oily saltwater
fish. It can also be made in a laboratory. Women use vitamin A for heavy
menstrual periods, premenstrual syndrome (PMS), vaginal infections,
yeast infections, “lumpy breasts” and to prevent breast cancer. Some
women with HIV use vitamin A to decrease the risk of transmitting HIV to
the baby during pregnancy, childbirth, or breast-feeding and men use it
to raise their sperm count. Some people use vitamin A for improving
vision and treating eye disorders including age-related macular
degeneration glaucoma, and cataracts. It is also used for
gastrointestinal ulcers, Crohn’s
disease, gum disease, diabetes, Hurler syndrome
(mucopolysaccharidosis), sinus infections, hayfever, and urinary tract
infections (UTIs). Vitamin A is also used for shigellosis, diseases of
the nervous system, nose infections, loss of sense of smell, asthma,
persistent headaches, kidney stones, overactive thyroid, iron-poor blood
(anemia), deafness, ringing in the ears, and precancerous mouth sores
(leukoplakia). Vitamin A is applied to the skin to improve wound
healing, reduce wrinkles, and to protect the skin against UV radiation.

Vitamin A is required for the
proper development and functioning of our eyes, skin, immune system, and
many other parts of our bodies. And bear in mind that taking large
amounts of vitamin A might harm the liver. Taking large amounts of
vitamin A along with medications that might also harm the liver can
increase the risk of liver damage. Do not take large amounts of vitamin A
if you are taking a medication that can harm the liver. So take your
supplements with caution and you will not come across any trouble, you

Vitamin A Overdose

There is a reason why people shouldn’t
overdose and it is because it is a fat-soluble vitamin and that simply
means that it gets stored in your body so taking too much Vitamin A is
something to be careful of. Vitamin A overdose and toxicity “danger
levels” start to develop when taking in around 25,000IU or more of
Vitamin A per day for a long time. And if you wondering how does the
overdose occur? Well it occurs by either consuming too much preformed
Vitamin A or by taking too many supplements with preformed Vitamin A and
it is absorbed quickly and eliminated slowly. Vitamin A toxicity can
also be from long-term low intakes or short-term high intakes. And
children are more vulnerable to Vitamin A overdose and toxicity than
adults because children can reach toxic Vitamin A levels at smaller
doses. And also be careful if you’re
pregnant, too much Vitamin A, especially Vitamin A supplements, can
cause birth defects. Talk to you doctor first and a safer bet is to take
beta carotene instead, but they do have some minor side effects and the
only side effect know by taking too much vitamin. A beta carotene is
your skin starts to turn colors. It becomes like a yellow-orange tint
and no one wants to look like that, so it would be best to consult with a
professional and they will tell you how many to take and so on. And the
extra beta carotene gets stored in the fat under your skin and will
show through.

Following instruction is the best key; if you do you have any trouble at the end of the day and if you don’t you will face certain results. It’s
best you do what the doctor says and you will not come across any
concern. To avoid any complications in your pregnancy its best to check
with your doctor first and let them decide on which ones are good for
you to take.

Vitamin A overdose side effects

Taking a multivitamin can play a
vital role in promoting your overall health, as with any substance,
taking more than the recommended amount can cause mild to severe health
problems. And some individuals may have unique vitamin and mineral needs
that fall below the traditional nutrient recommendations set forth by
the Food and Drug Administration (FDA). So now you are aware of the
dangers of overdosing and the signs of it are not that pleasing, no one
should go through that. An overdose of vitamin A can lead to hair loss,
headaches, yellow pigmentation, blurred vision and liver damage.
Consuming doses more than 25,000 IU, which is five times the RDA, can
cause all these problems which is considered an overdose. Symptoms of
overdose include low grade fever, dry skin, and sore mouth, bleeding
gums, drowsiness, diarrhea and severe vomiting. These symptoms disappear
on withdrawal of the vitamin. Overdosing on some vitamins can throw off
your body’s ability to absorb and/or use other nutrients, putting you
at an increased risk of suffering from both an overdose of one vitamin
and a deficiency of another. And if you do suspect that you suffering
from these symptoms I would seriously suggest that you visit a doctor
and let him/her know what you dealing with and then they can take it
from there.

Don’t just sit and say it’s
just a minor problem and it will go away, its best to act now upon a
problem than dealing with it later when it has caused a whole lot of
