We live in a society in which we are in a state of constant fear of diseases. From when we are young we are taught repeatedly to wash our hands before every meal and to eat an apple daily. Moreover, we are catechized on a regular basis to bundle up so we do not catch a cold or pneumonia. Likewise, our doctors advise us to visit them annually to make sure we don’t have deficiency related disorders such as scurvy or anemia. What if there is a vitamin that could aid in preventing the aforementioned illnesses? Would it not be worth a try? Consider this an introduction to vitamin C! Details on this “wonder vitamin” are elaborated in the subsequent paragraphs!
Several unique attributes distinguish vitamin C from other substances. Vitamin C is a snow white, powdery sugar that is water soluble (Nicolaou & Montagnon, 2008). As evidenced from its basic chemical formula of C6H8O6, vitamin C is organic. Additionally, in a more complex analysis, we will find that it is both an alcohol and an acid which has a carbon ring (has 6 carbons) and a double bonded oxygen atom (Dubé, 2011). Two major types of vitamin C exist today, ascorbic acid and dehydroascorbic acid. Ascorbic acid is in a simple, reduced form whereas dehydroascorbic acid is in an oxidized (positively charged) state (Nualart, Rivas, Monticenos, et al, 2003). Vitamin C is prevalent in an amplitude of foods. We can find it in several types of citrus fruits including oranges, tangerines, grapefruit, and clementines. Moreover, green and red vegetables are a rich source for this vitamin. Bell peppers, strawberries, tomatoes, peas, and broccoli all fall into that category. Oranges are one of the best sources with 90 mg of vitamin C per 100 grams. On the other hand, peas and tomatoes have...

The more the merrier right? Overtime people have continuously believed that vitamin supplements help the human body sustain a healthier body and well-being, however, have failed to realize the harm that vitamin supplements can do to the body; this is indicated by Paul Offit, the author of “The Vitamin Myth.” He states that over time researches and various studies have proved that Linus Pauling, the soul of the vitamin myth, statements of what vitamin supplements could do for the human body and or life. For example, the National Cancer Institute in 1994, researched smokers who were given various supplements over a period of time however those who were given supplements eventually showed signs of a more dangerous health state than those who did
UV exposure to skin can generate reactive oxygen species (ROS) that cause direct chemical alteration in collagen and increase matrix metalloproteinase (MMP) production leading to collagen break down. In addition, ROS produce mediators that cause skin inflammation. Vitamin C neutralizes ROS and is equally effective against UVA (320-400nm) and UVB (290-320 nm) that are produced due to UV exposure and causes skin-aging and sunburns respectively. Vitamin C is most effective as it exerts its action interacellularly and extracellularly (7).

A well-balanced diet contains all the necessary vitamins, and most individuals who follow such a diet can correct any previous vitamin deficiencies. However, persons who are on special diets, who are suffering from intestinal disorders that prevent normal absorption of nutrients, or who are pregnant or lactating may need particular vitamin supplements to bolster their metabolism. Beyond such real needs, vitamin supplements are also often popularly believed to offer "cures" for many diseases, from colds to cancer; but in fact the body quickly eliminates most of these preparations without absorbing them. In addition, the fat-soluble vitamins can block the effect of other vitamins and even cause severe poisoning when taken in excess.
