Introduction:
Vitamins are substances our bodies can’t make. Therefore they need to be obtained through our diet. If we didn’t get vitamins in our diet we would die or be seriously ill. (Precision Nutrition, 2014)
Vitamin supplements are mostly artificial tablets, powders, injections and liquids. They are intended to enhance vitamin intake or supply vitamins to the body that you are unable to ingest through your diet. 54% of women and only 46% of men globally, take vitamins and/or mineral supplements daily. (Precision Nutrition, 2014)
Over 56% of Americans with an annual income of over $90,000 take vitamin supplements. Although 70% of Americans with an income of lower than $24,000 don’t take them. (Gallup Well Being, 2014)
That means that the less wealthy can’t always afford vitamin supplements. But do they need them? Here are all the different types of vitamins (see table below). It could be argued that the general public don’t know the difference between all of them, or even know there were that many.
How does Vitamin C work?
Vitamin C is a vitamin found in sources of fruits and vegetables, especially citrus fruits.
Historically Vitamin C was used for preventing and treating scurvy. Scurvy is rare now a days but sailors, astronauts, pirates and people who spend long periods at sea without fruit and vegetables are more prone to Vitamin C deficiency, which leads to scurvy. (NASA, 2013)
Today people take Vitamin C supplements to prevent the common cold and infections. Although that isn’t always factually true. One scientist from Australia said, “It doesn’t make sense to take Vitamin C tablets 365 days a year to lessen the chance of catching a cold.” (Professor Harri Hemila, 2013)

In 2011, the University Of Minnesota took women who take vitamins daily and studied them(Offit, Paul., 2013). The result was the same in that there was no supporting evidence that favors Pauling’s claims and statements. In conclusion, the general public believed the words of a man who had no specific evidence to support his own claims over researches done by trusted establishments who had evidence towards their own claims against Linus Pauling. Vitamin D is essential in many aspects especially during growth periods such as adolescents and infancy as indicated by Winston Koo and Nitin Walyat who are the respective authors of “Vitamin D and Skeletal Growth and Development”.

When it comes to supplements, I feel that there is a lot of misleading health benefits from actually taking them. As I learned from monitoring my own nutrient intake, our diet sometimes is lacking of important vitamins and minerals. There are so many supplements that promise curse and longevity by taking their pill, however, their claims have not been to my standards scientifically supported. In contrast, vaccines still have a negative stigma or attitude concerning side-effects which sway parents away from having their children receive these lifesaving vaccines. There is volumes of clinical research that supports the benefits of vaccines against deadly diseases and dispels most concerns over any serious
The body can manufacture only vitamin D; all others must be derived from the diet. Lack of them causes a wide range of metabolic and other dysfunctions. In the U.S., since 1940, the Food and Nutrition Board of the National Research Council has published recommended dietary allowances (RDA) for vitamins, minerals, and other nutrients.
Vitamin C also known as ascorbic acid is needed for growth and maintenance of healthy tissues, especially skin, blood vessels, bones, gums, teeth. Vitamin C aids in resistance against infection and healing of wounds. It also helps the body absorb iron from food. Vitamin C can be found in green vegetables, potatoes, tomatoes and citrus fruits such as oranges and lemon. A lack of vitamin C can cause scurvy, iron deficiency and poor wound healing. A healthy diet should include a high amount of vitamin C because the human body cannot produce its own vitamin C.
When one hears the three words: vitamins, nutrients, and minerals, they think of one thing-being healthy and noticing what your intake is daily. Nutrition is all about vitamins and nutrients.

A well known and commonly used in commercials for orange juice vitamin is vitamin C. Vitamin C or ascorbic acid is important in the synthesis and maintenance of connective tissues. The lack of vitamin C will result in a sickness called scurvy. Scurvy harms the gums, mucous membranes, and the skin. Another well-known vitamin and is also used to commercial to give more information about this beverage is the vitamin in milk. The vitamin in milk is vitamin D.

Secondly, nutrients are how the body assimilates certain compounds. Nutrients are classified in 5 major groups: proteins, carbohydrates, fats, vitamins, and minerals. One of the five nutrients is carbohydrate. The carbohydrate group principally consists of sugar, starch, dextrin, cellulose, and glycogen. In more basic terms, carbohydrates are sugars needed by human and other living organisms. Some types of foods that contain carbohydrates would be candies, ice cream, fruit juice, soda, chocolate bars etc. Lastly, vitamins are connected to minerals. Minerals are also a very important part of a healthy person. There are 11 major groups of minerals. They are: calcium, chromium, copper, iodine, iron, magnesium, manganese, phosphorous, potassium, selenium, and zinc. All these terms look very familiar if one has taken chemistry. These are the elements of our world. One of the more common minerals that most people have heard of is calcium. Calcium also helps with the structure and strength of teeth and bones. Vitamins and minerals work together to help humans maintain a healthy body. For example, vitamin D works with calcium to help for and maintain the strength of teeth and bones.
