When you go to a pharmacy , one can’t but help notice the hundreds of vitamin bottles lined up on the shelves. But do we really need to takes these vitamin supplements at all ?
That’s a difficult question to answer. Are you taking a well-balanced and healthy diet containing fortified rice and bread, meat, green vegetables, citrus and other fruits and fish ? Are you getting enough sunlight ?
Whether or not you need to take supplements will depend on all these factors, and on your current condition. For example, do you have certain disease, are you pregnant ?
But if you don’t take enough of a certain vitamins, this will lead to vitamin deficiency. The word vitamin was actually coined by a guy called Funk. He called it “vital amine” in 1912, when it was discovered that amine extracted from rice polishing could prevent beriberi.
Since then, vitamins are considered essential organic compound for life, because the human body cannot synthesize them. Vitamins A, D, E and K are classified as fat-soluble vitamins, whereas B, C and D are classified as water-soluble vitamins. Vitamin A was the first fat-soluble vitamin to be discovered (that is why it is called A) in 1913.
Vitamin A is essential for vision (especially your eyes` adaptation to dark surrounding) , your immune response (where your body mount its defense against infections), cell growth and repair, bone growth, reproduction, maintenance of the surface lining of the eyes, and maintenance of the surface linings of the eyes, and maintaining the lining of your respiratory, urinary and intestinal tracts.
If you have deficiency of the vitamin, then you’ll get abnormal dark adaptation. When this happens, you will find it difficult to see in the dark. You might have dry skin, dry hair, broken finger-nails, and decrease resistance to infections.
