Vitamin C - Overview, History, Benefits, Precaution, Dosage

What is Vitamin C?

Vitamin C is widely known as an essential nutrient for beauty. It is a water-soluble vitamin which is known as ascorbic acid in scientific terms. It is an essential vitamin that helps maintain the health of the skin and mucous membranes and has a powerful antioxidant effect.

A healthy level of vitamin C protects from scurvy and makes the skin firm, preventing blemishes, improving immunity and preventing colds, increasing resistance to stress and many more.

The human body is required to intake vitamin C from other sources. Many mammals can synthesise vitamin C from glucose in their bodies, but the human body cannot synthesise vitamin C because they lack the enzymes necessary for synthesis. Humans can find this vitamin with vitamin C name or ascorbic names. It is a scientific name and usually exists in the form of reduced L-ascorbic acid or oxidised L-dehydroascorbic acid.

Absorption of vitamin C

Vitamin C or Ascorbic acid is an essential compound for the production of collagen, an essential protein for the bones and tendons. A lack of vitamin C absorption and a lack of vitamin C in the body means a lack of collagen synthesis resulting in weakened blood vessels and bleeding. This is scurvy. When the body consumes vitamin from a plant or animal source, it is absorbed by the upper part of the small intestine and transferred to the liver. It is transferred or distributed throughout the body by the blood from the liver. As said, humans do not produce vitamin C naturally in their bodies like pigs, and monkeys. We need to consume it to see its benefits for the skin and body. 

Vitamin C is odourless, white and a bit sour. It is easily dissolved in the water and easily damaged by heat, air, etc. Hence, it is ideal to consume vitamin C only in raw form without cooking or heating for maximum absorption of vitamin C.

History of Vitamin C

Vitamin C is discovered as a substance that prevents “scurvy”. It is a disease which is caused by vitamin C Deficiency. In ancient times, about the 16th to 18th centuries, due to a lack of fresh ingredients, many sailors died from scurvy. Scurvy is a scary disease which causes the blood vessels throughout the body to become fragile, causing bleeding from the gums and internal organs, leading to death. It was a hilarious movement. In 1747, British naval physician James Lind discovered that scurvy could be prevented by having sailors eat citrus fruits such as oranges and lemons daily. Hence, a ton of crus fruits is provided to the sailor. Sailors start drinking lime juice and lemon juice every day to prevent scurvy. Likewise, citrus fruits rich in vitamin C are discovered to prevent scurvy. Well, in 1920, British chemist Drummond found the presence of vitamin C in citrus fruits which helps in scurvy.

Next in 1928, Hungarian scientist Alberto St. Gyorgy isolated a new sugar-like substance from the adrenal glands of cattle and named it hexuronic acid. During the same time, some scientists isolated vitamin C from lemons and found that it was the same substance as hexuronic acid. Hence, it is a confirmation of vitamin C. Day by day, the benefits of vitamin C are evolving and now its use is not limited to scurvy. Scientists perform thousands of studies and now it is used for skin, anaemia and many more.

Vitamin C helps to prevent melanin pigmentation by inhibiting the action of tyrosinase and has the effect of maintaining translucent skin. Hence, it helps to get white skin.

The generation of interferons, which have antiviral effects, is aided by vitamin C. The liver enzymes involved in drug metabolism are activated by vitamin C, which also improves detoxification.

Adrenaline is released from the adrenal glands when the human body experiences stress, raising blood pressure and blood sugar to prepare the body for defence. Since vitamin C is required for the production of adrenaline, stress consumes large amounts of vitamin C when it is needed to make up for the shortage. Stress is not just mental stress like pressure, tension, and anxiety. Stress-inducing variables include cold or heat, lack of sleep, noise, and smoking.
