Vitamin C, also known as vitamin C, is an indispensable vitamin in the daily diet. The health effects of vitamin C have been recorded in a long history. As early as 400 AD, Hippocrates, the father of Western medicine, described in the literature the symptoms of scurvy caused by vitamin C deficiency. It was just that people did not know that the culprit of scurvy was actually the lack of vitamin C.
Vitamin C is an essential nutrient. Deficiency causes scurvy and is related to many physiological functions.

What works in the body is left-handed and right-handed vitamin C.
Take vitamin C from natural foods and don’t worry about overdose. However, excessive intake of nutritional supplements may cause a risk of stones.
Vitamin C may interact with many drugs. People who supplement from food need not worry too much, but people who take supplements should pay attention.
How to eat vitamin C? How much should I eat? Please directly compare the table in the text.

What is Vitamin C? What are the physiological effects?
Vitamin C (also known as vitamin C, ascorbic acid) is a water-soluble vitamin. It is usually contained in fresh vegetables and fruits. However, because it is unstable, it will be affected by the storage state and cooking method. The final vitamin C content of food. For example, high temperature and excessive cooking will destroy many vitamin C. In addition to being common in natural fruits and vegetables, vitamin C is also often added to foods. The purpose is usually to act as an antioxidant to protect food, or as a nutritional additive for humans.

Vitamin C plays a fundamental role in human beings. In other words, if vitamin C is not supplemented from the outside, the body will have problems or even die. Most of the vitamins are essential nutrients for humans, which means that the human body cannot make these nutrients. Interestingly, some human essential nutrients are not necessarily necessary for other animals! But vitamin C is not only something that humans cannot synthesize on their own. For example, monkeys and guinea pigs, like us, cannot synthesize themselves. They have to ingest it from food.

What effect does the lack of vitamin C have on the body
Most of the problems caused by vitamin C deficiency will come from its related physiological functions. Long-term lack of vitamin C may cause scurvy, fatigue or laziness, weakened connective tissue and fragile microvessels.

The initial symptoms of vitamin C deficiency may include fatigue (probably because carnitine synthesis is blocked), general weakness, and gum inflammation. If it continues to lack, the structure of the synthesized collagen will be damaged.

In addition, vitamin C deficiency may also lead to iron deficiency anemia because of increased bleeding and vitamin C deficiency, which affects the absorption of non-blood iron. In children, bone disease may also occur.

The relationship between vitamin C and disease and human health
Vitamin C is often considered to have miraculous effects. Some friends of the natural remedies often suggest that "extra" vitamin C supplementation can prevent or even treat cancer. The extra mentioned here refers to the intake of nutritional supplements other than "natural food". But what is going on? Let's take a look directly at the related research!

Cancer prevention
So far, there is inconsistent evidence that whether vitamin C in the diet can affect cancer risk. The results of most clinical studies support the appropriate supplementation of vitamin C alone or with other nutrients, and they do not provide any cancer prevention benefits.
In such studies, the concentration of vitamin C in the blood before or after supplementation is usually not measured, and this may affect the researchers' interpretation of the results. We mentioned earlier that the concentration of vitamin C in plasma and tissues is tightly controlled in the human body. Taking more than 100 mg of vitamin C a day seems to saturate the cells. In addition, when taking more than 200 mg a day, the plasma concentration will only increase slightly. If the subject's vitamin C concentration is close to saturation when entering the study, the effects of supplementation may be limited, or even the difference cannot be measured.

Cancer treatment
Research in the 1970s supports that high-dose vitamin C has a positive effect on the quality of life and survival time of patients with advanced cancer. However, some subsequent studies did not support it. Studies have shown that patients with advanced colorectal cancer supplement 10 grams of vitamin C or placebo daily, and the results are not significantly different.
New research suggests that the way vitamin C is administered, oral and intravenous, can also explain the contradictions between past research results. Most of the interventional trials are only oral trials. Oral vitamin C, even given a large dose, can only increase the blood concentration to 220 micromol/L, but intravenous injection can increase this concentration to 26,000 micromol/L.
