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.
