Vitamins: What Are They?

Scientifically speaking, vitamins are chemical substances that are essential for the release of energy within the body. It is an organic compound( substance formed from two or more elements chemically united in fixed proportions)required as a nutrient in tiny amounts by an organism. a compound is called a vitamin when it cannot be synthesized in sufficient quantities by an organism and must be obtained from the diet. [1]

Why Vitamins Are Important

Millions of people pop a multivitamin every day with little evidence that it does any good. Yet many researchers say a multivitamin has a role as a very expensive insurance policy, says David Shardt, a senior nutritionist at the Center for Science in the Public Interest. Certain vitamins like vitamin C helped combat and thwart off scurvy and rickets. These diseases have nearly disappeared in this country and other developed ones.[2]

There's a lot of controversy about what to take and how much to take. We know they're important for growth and development and for the healthy maintenance of our cells, tissues, and organs. If we are lacking certain vitamin, a deficiency can occur which can lead to illness and disease. But their importance has been questioned because some people do not take vitamins and exhibit the signs of a healthy body.

Some Research

One study suggested not taking singular vitamins because they may deplete another. For example, folic acid supplementation may deplete Zinc, and vitamin B6 supplementation may reduce magnesium levels. Zinc and magnesium each play an important role in both cardiovascular health and brain function.[3] This might suggest taking a multivitamin to ensure a proper balance of each vitamin.

Another study suggests that 7/10 children in the United States have low levels of vitamin D, raising their risk for bone and heart disease. This equates to about 7.6 million children with a deficiency and well over 50.8 million have levels considered insufficient.[5]

A Shortcut to Health?

But some people think that if you take vitamin pills by the handful, you dont have to bother watching what you eat. It is easy to see the attraction of an approach whereby you can exist on junk food, have a terrible lifestyle and still be 'healthy'. Other people take a less extreme view and try their best to follow the prevailing health advice. They recognize that they will fall short of the ideal and take vitamins as a kind of insurance policy. Doctors, too, thought this was a good idea. After all, in laboratory tests vitamins E and C had a powerful effect on the 'free radicals' that are linked to all sorts of medical problems from cancer to heart disease. Many studies have since shown that vitamins from supplements do not act on the body in the same way as vitamins from foods.[4]

I have known of people being cured of various sicknesses due to a vitamin deficiency so I do think they are helpful. I don't think they should be used in place of a healthy diet. - jennyhooah (twitter) 0

Vitamins definately help your body if used in the right proportions. Vitamins should be taken "as needed" and not for the sake of it as too much of a certain vitamin is also harmful. - _fraz_ (twitter) 0
