Vitamin C has a good health-preserving effect on human body, so in real life, many people will supplement vitamin C every day.
Can vitamin C enhance human immunity?
Vitamin C can promote the growth of lymphocytes in vivo, has strong antioxidant capacity, and can prevent the harm of free radicals to human health. In addition, vitamin C can also promote the absorption of iron in the intestine and achieve the effect of preventing and treating iron deficiency anemia.
White blood cells in human body are immune cells, which are rich in vitamin C. When human body is infected by virus or bacteria, vitamin C can enhance the chemotaxis of neutrophils and improve their antiviral ability.
Once vitamin C is lacking in the body, collagen cannot be synthesized normally, and there will be problems in cell connection, which will easily lead to scurvy. If there is a serious shortage of vitamin C in the body, the emergency ability and immunity of the human body will drop rapidly.
It can be seen that vitamin C can really enhance human immunity and achieve the effect of improving antiviral ability. Therefore, people with poor resistance can properly supplement vitamin C under the guidance of a doctor.
So, what are the precautions when supplementing vitamin C?
First, people with weak renal function should use it with caution
Vitamin C can really improve immunity and disease resistance, but if people suffer from kidney disease and weak renal function, they must reduce the frequency of vitamin C supplementation. When people with weak renal function take a large amount of vitamin C, the body can't absorb too much vitamin C, which will be metabolized by the kidneys and then excreted with urine. This will greatly increase the burden of protecting the kidney, thus making the kidney disease more serious.
Second, patients with digestive tract diseases are prohibited.
If you suffer from digestive tract diseases, such as gastric ulcer, duodenal ulcer, hyperacidity, gastritis, etc. Once taking vitamin C, it will lead to hyperacidity and gastric reflux. This will cause a certain burden on the stomach, and it will also lead to the aggravation of inflammatory symptoms in the stomach. In addition, in people with digestive tract ulcers, vitamin C will irritate the surface of the ulcer, leading to the risk of perforation and deterioration of the ulcer.
Third, it is not advisable to take it in large quantities.
When the human body can not absorb too much vitamin C, it will cause diarrhea, abdominal distension, abdominal pain, nausea, pantothenic acid and other stomach discomfort symptoms. Moreover, the excess vitamin C in human body will enter the kidney with blood, which may easily cause kidney calculi's disease or kidney disease. Therefore, when taking vitamin C, you must supplement it in strict accordance with the doctor's advice.
To sum up, vitamin C has many effects on human body, such as antioxidation, whitening, delaying aging and promoting bone development. But also has high antiviral ability. However, when taking vitamin C, you must follow the doctor's advice. The general population can maintain the body's demand for vitamin C by eating more green vegetables and fresh fruits in their diet, without deliberately supplementing them.
