History Of Vitamin C:

Two hundred fifty years ago, sailors didn’t know if they would return alive or not because of scurvy. This was because of their eating pattern. Sailors consumed fruits and vegetables early and then served only cereals and meats.

The first nutrition experiment ever performed on a human being was devised in the mid-1700s to find the cause of scurvy. A British physician, James Lind, divides 12 people into six groups. The first one was (Cider), the second one was (Vinegar), 3rd (Sulfuric Acid), 4th (sea water), 5th (Oranges and Lemon), and 6th (Strong laxatives mixed with spices). Each pair received a different supplemental ratio. Those receiving citrus fruits recovered quickly. Nearly 200 years later, that factor was found; it was a six-carbon compound similar to glucose and named “Ascorbic Acid.”

What is vitamin C good for?

Vitamin C as an antioxidant:

Vitamin C can quickly lose electrons; this allows vitamin C to perform as an antioxidant. It defends the body against free radicals. Vitamin C gives up electrons to stop free radical damage, then reaccept them to become re-activated. This recycling of Vitamin C is key to maintaining a reserve of antioxidants in the human body.

Vitamin C is like a bodyguard of the body. In cells and body fluids, Vitamin C protects tissue from oxidative stress. It also enhances Iron absorption by preventing oxidation of Iron.

Vitamin C as a cofactor in Collagen Production:

  • It helps to form the fibrous structural protein of connective tissues, known as collagen. It serves as the matrix in which bones and teeth are formed. 
  • When a person is wounded, collagen glues the separated tissue together, forming scars. Cells are held together by collagen. 
  • It is crucial in artery walls, which expand and contract with heartbeat beat, and in the thin capillaries, which withstand a pulse of blood every second.
  • The body makes proteins by joining the chains of amino acids together. During the synthesis of collagen, a lysine is added to the protein chain. An enzyme adds an OH- group to proline and lysine, and hydroxylate and hydroxyproline are formed. This conversion requires vitamin C and iron. Ironworks as a cofactor and vitamin C protects iron from oxidation and allows it to perform its action.

As a cofactor in other reactions:

  • Vitamin C helps hydroxylation of carnitine, a compound that transports long-chain fatty acids into a cell’s mitochondria for energy metabolism.
  • Vitamin C converts the amino acids tryptophan and tyrosine to neurotransmitters, serotonin, etc.
  • It also assists in making hormones, including thyroxin, which regulates the metabolic rate; when metabolism speeds up in extreme physical stress, the body’s use of vitamin C increases.

In disease prevention:

Vitamin C helps prevent cancer, heart disease, cataract, and other diseases. In one study, they found that a vitamin C supplement or Vitamin C alone reduces breast cancer cases by 23%. So it is effective in cancer because vitamin C reduces the damage that free radical causes. It also lowers blood pressure.
