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.
