What Does Vitamin C Do?

Vitamin C is the most widely spread dietary supplement, a very important nutrient, which can be obtained from a variety of plants, and through animal liver. Vitamin C is internally synthesized by almost all animals, except humans, chimpanzees, gorillas, guinea pigs, bats, and some species of birds

Humans can obtain vitamin C only from foods. The recommended daily intake of vitamin C for adult women is 75mg, and for adult men is 90mg, but, generally, the need for a vitamin C depends on several different factors, the age, the health condition, and some people need 10 times more of the vitamin C than the others.

Vitamin C has a very important protective role in our bodies. It is widely known that vitamin C helps our bodies fight the cold and flu, but it also plays a role in cold and flu recovery. It does not mean that it eliminates the risk of either of the two. It boosts immune system by synthesizing minerals, such as calcium. It is also important for brain functioning. It rebuilds bones, tissue and blood vessels, and plays a huge role in the healing processes.

It is a powerful antioxidant that neutralizes free radicals. Free radicals are by-products of cell metabolism, which cause lack of oxygen in cells. Lack of oxygen in cells causes collagen breakage. Free radicals can also attack DNA and fats and proteins in our body. This is why vitamin C is believed to help fight cancer, since the damage to DNA is believed to be one of the causes of it. Whereas vitamin C helps fighting cancer, it is also proven that cancer cells do not respond as well to chemo-therapy when high dosage of this vitamin is present in a human body.

It helps several enzymatic reactions, and is especially important for collagen production in the skin. It has been proven that people who take more vitamin C in their diet have fewer wrinkles, do not have problems with skin dryness, which is related to the old age, and generally look younger than those who don’t.

Vitamin C has a preventive role in heart diseases, cataract, joint diseases, which are all more or less associated with vitamin C deficiency. Vitamin C prevents hardening of the arteries, which leads to atherosclerosis, which happens when cholesterol, fat, and other substances form the so-called plaque, the hard structures that build up in the walls of arteries.

Vitamin C also plays a role in iron absorption, and in regenerating one’s vitamin E supplies. In the past it was most popular for treating the illness called scurvy, when it was discovered that vitamin C has antiscorbutic factor, hence vitamin C is also known as L-ascorbic acid or L-ascorbate. Scurvy used to be very frequent disease among sailors, which is why the ships used to be loaded with lime, in order to prevent this disease. This is why British sailors used to be called “limeys” in the past.

Vitamin C kills candida, viruses, parasites, bacteria. It supports the good bacteria in our gut. It can neutralize bacterial and environmental toxins. It fights stress, and can also act as an antidepressant. It also helps lowering high cholesterol.

Vitamin C deficiency can cause oral health problems. Vitamin C helps gums be healthy and strong, and prevents gum bleeding.

The human body is not designed to function on a single high dose of vitamin C a day, because this vitamin does not remain in a body for very long. Vitamin C is disposed of through urine in just a few hours. Therefore, it is important to obtain vitamin C throughout a day, through food, or health supplements.

  1. Vitamin C is the most important vitamin when common cold is in question. It makes our immunity stronger.

  2. Common cold can be prevented successfully with the combination of vitamin C and Zinc. They also reduce wound recovery time and are great for the skin. Their antioxidant features are very well known.

  3. Vitamin C will boost your immunity and can prevent some infectious diseases and improve the efficiency of some medicines. It is a vitamin which is not stored in our body. Therefore it is important to take it regularly through food or supplements.

  4. Normally, our vitamin C levels are low all the times. I have been taking high doses of vitamin C when I had cold, but to be honest, it didn’t make any difference whether I take high doses of vitamin C or not. I can only recommend to take Zinc together with vitamin C.

  5. When the allergy season begins I start taking 500 mg/day. I also don’t have the habit to eat vegetables; otherwise I wouldn’t be worried about my vitamin C intake.

  6. Both vitamin C and vitamin D can prevent oxidative damage. However, vitamin D deficiency is much more frequent that vitamin C deficiency. The cause for this is that people don’t get enough sunlight exposure and the number of foods rich in vitamin D is not so high. On the other hand, there are many foods rich in vitamin C. Both these vitamins are really valuable but the real problems occur when a person is deficient in any of them.

  7. It is difficult to say whether high doses of vitamin C will help you or not. In my case, poison oak leads to severe allergic reactions. Only an oral antihistamine seems to work. You should also learn more about vitamin D. It is very important to prevent vitamin D deficiency, but at the same time some studies have shown that it can prevent up to 17 types of cancer.

  8. Although vitamin C is mainly used in the treatment of cold and other respiratory problems, its use is still controversial. There have been massive studies concerning the effects of daily intake of vitamin C in the prevention of common cold. There was no evidence that it was useful. The people who got cold while taking vitamin C every day still had the same symptoms, but they lasted a bit shorter. However, another study conducted among people who live and work in extreme conditions reduced the risk of getting cold by 50%.

  9. Is there a difference between ascorbic acid and citric acid or are the two the same?

  10. If a persons blood work has on lab results “ALERT! NO VITAMIN C ” how could they only develop tiredness and weakness and no other symptoms ? They have had this for 2 + years.
