Vitamins A
Vitamin
A is a family of fat-soluble antioxidant Vitamins
known in its dietary form as retinol. This antioxidant
Vitamin plays a crucial part in vision, bone growth,
reproduction, cell division, and cell differentiation.
It
is known as retinol for a good reason;
this is the best Vitamin to generate pigments
in the retina.
In addition, Vitamin A helps
form and maintain healthy teeth, skeletal
and soft tissue, mucous membranes, and
skin.
Vitamin A is the greatest Vitamin
when it comes to the promotion of good vision,
especially in dim light.
It is no overstatement
to say that Vitamin A allows you to see in
the dark, as this antioxidant Vitamin catalyzes
the production of rhodopsin, the visual pigment
used in low light levels.
Also, Vitamin A aids
the immune system, helping fight off infectionsby making white blood cells
that destroy harmful bacteria and viruses. Vitamin
A particularly helps lymphocytes, a type of white
blood cell, fight infections more effectively.
Likewise, Vitamin A is needed for the production
of red blood cells.
Vitamin A moreover promotes healthy surface linings
of the respiratory, urinary, and intestinal tracts.
This Vitamin adds to the integrity of epithelial
tissues and mucous membranes as a physical barrier
to infection.
In this arrangement, it becomes
more and more complicated for bacteria to penetrate
the body and cause infection.
It may also be required for reproduction and
breast-feeding.
You can buy Vitamin supplements of this at Vitamin
stores and Vitamin shoppes worldwide.
Otherwise,
retinol is ingested in a precursor form, which
can be obtained from natural Vitamin sources like
animal products like milk and eggs.
Animal products like those contain retinyl esters,
whereas plants like carrots and spinach contain
pro-Vitamin A carotenoids.
Breakfast cereals as
well as a majority of fat-free milk and dried
nonfat milk solids sold in the United States are
fortified with Vitamin A to replace the amount
lost when the fat is removed.
Carrots, spinaches and other plant sources of
Vitamin A are not as well absorbed as animal sources.
Otherwise, the market is saturated with liquid
Vitamin A products, let alone puritan Vitamins.
In all, beta-carotene, which has antioxidant
properties, is a commendable precursor to Vitamin
A.
