Historical Development
Vitamin B12 is also an essential element of nutrition. It has a great effect on human metabolism. Looking back to the past, the world did not know about this thing at the beginning. In modern times, with the advance of science and technology, researchers began to pay attention to exploring. At the beginning, it was isolated from the liver, and its structure was later known. At that time, extraction was difficult, the yield was scarce, and the price was also high.
However, researchers have been unremitting, and they have been studying for many years. Gradually understanding the path of its biosynthesis, it can be achieved by artificial methods. Since then, vitamin B12 has been mass-produced and widely used. In medicine, it treats anemia diseases; in food, it is a strengthening agent; in animal husbandry, it promotes the growth of livestock and poultry. Its application is becoming more and more popular due to the efforts of researchers and the progress of science and technology.

Toxicity Research
In modern times, the product of vitamin B12 has been studied, and its toxic properties are very harmful. I often think about it. So I conducted toxicity research by ancient methods. Take several doses of vitamin B12 and divide it into various substances to try. After the mice were taken, they stopped as usual at the beginning, and they may have a state of fatigue, eating less and moving less. And flowers and plants are planted in the soil where this agent is applied, and their leaves gradually wither and their vitality is not prosperous. From this point of view, although vitamin B12 has its uses, excessive application of it also shows toxicity. It can disturb the mice, but it can damage the life of flowers and plants. Researchers should be careful and understand its advantages and disadvantages. The only way to use the drug is to make this agent beneficial and harmless to the health of the world and the life of all things.

3. ** Other **: Some leavened foods, such as fermented bean curd, etc., or contain a small amount of vitamin B12. However, due to the small content, it is used as the main source of vitamin B12. But fermented bean curd has a special taste, which adds color to the food, or it can also add a little bit of this vitamin.
What are the symptoms of vitamin B12 deficiency?
If people are deficient in vitamin B12, all kinds of diseases occur.
Qi and blood diseases are the most common. Vitamin B12 is very important for hematopoiesis, and megaloblastic anemia occurs when it is deficient. Patients often feel exhausted, their complexion is yellow and dull, their lips are pale and unproud, they are panting at every turn, and their hearts are often palpitated.
The nervous system is also affected by it. The brain is disnourished, people may see dizziness, memory is sharply reduced, they are in a trance, and sleep is disturbed. And the limbs may feel numbness and tingling, and when walking, they may step on cotton wool, and their steps are unstable. This is all due to blocked nerve conduction.
The disease of the digestive system cannot be ignored.
If a child lacks vitamin B12, it will hinder growth and development. Intellectual development is delayed, movement is clumsy, language is delayed, body size is short, and bones are weak.
If a woman lacks vitamin B12 during pregnancy, fetal development may be affected, and there is a risk of deformity and premature birth.
In summary, vitamin B12 is of great significance to human health. If there is any doubt of deficiency, seek medical treatment as soon as possible, and make up for it with drugs or diet to restore peace to the body.
How to Supplement Vitamin B12 Properly
If you want to correct vitamin B12, follow a reasonable method. Vitamin B12 is very important to human beings, and it is important for blood creation, spiritual transformation, etc. If it is lacking, it will cause illness or health, such as blood and spiritual function.
If you want to get enough vitamin B12, the first way to promote diet. It is mostly stored in physical foods, such as meat, beef and sheep. Meat is included; poultry eggs are also the source, such as eggs, eggs, etc.; sea food such as rice, especially rich in this nutrient. Daily food, it is appropriate to eat such foods to meet the needs.
However, if it is due to special reasons, such as vegetarians, because their food does not contain this nutrient, or if they have stomach diseases and malabsorption, the diet should not be enough. In this case, it can be used to fill the body. According to the instructions of those who can follow, it is appropriate to fill the vitamin B12, and take it according to the amount. Do not increase the body weight by yourself to avoid harm.
In addition, human absorption of vitamin B12 requires the help of factors. Factors are produced by the cells in the stomach wall. If the stomach is sick, factors are generated or affected, resulting in poor absorption. Therefore, the stomach is also an important factor. Daily food, avoid overeating, and eat less spicy, cold, and oily things, so as not to damage the stomach.
In this way, the positive vitamin B12 requires food, food, and health, and the spleen and stomach. In this way, the body can be fully and healthily.
What are the dangers of excessive intake of vitamin B12?
The harm of excessive intake of vitamin B12 has been known since ancient times.
A woman's body is a body that reconciles yin and yang, and has smooth qi and blood. Although vitamin B12 is necessary for the human body, it has great contributions to hematopoiesis and the health of the nervous system. However, the extreme will be reversed, and excessive intake is also a scourge.
If you eat it too much, it will disturb the state of blood first. Blood is the river of life, its flow is orderly, and its quality is balanced. Excessive vitamin B12 into the body may cause the blood to be sticky like a paste and stagnant. In the veins, the blood is difficult to travel, the light ones are dizzy, the body is tired, just like clouds and fog covering the sun, and the yang energy cannot be stretched; in severe cases, blood stasis is endogenous, blocking the veins, and the orifices of the heart and brain are congested. Stroke, thoracic paralysis may occur, endangering life, such as rivers bursting their banks and flooding.
And it is also harmful to the nervous system. The brain is the palace of the primordial spirit, and the spirit moves with qi, and qi nourishes with blood. Excessive vitamin B12 can cause nerve conduction disorders and the loss of divine power. Patients often feel numb limbs, like ants walking on them; or there are muscle tremors, unable to be autonomous, such as candles in the wind, swaying unpredictably. What's more, the mind is dizzy, the memory is gradually lost, the consciousness is in a trance, the wisdom of the past is no longer there, the family is worried, and the society is suffering.
Furthermore, the functions of the viscera are also affected by it. The spleen and stomach are the foundation of the day after tomorrow, the source of qi and blood biochemistry. Excessive intake of this substance, the spleen and stomach transport and lose their faculties, the stomach is stunned, nausea and vomiting, the diet is difficult to eliminate, the source of qi and blood biochemistry is deficient, and the organs are defective. The kidney is the foundation of the congenital nature, and the main collection of essence. The essence of the kidney may be damaged due to it, the waist and knees are weak, the ears are ringing and deafening, and the reproductive function is also disturbed by it. The plan of reproduction is related to the family and the country, so how can Although vitamin B12 is good, it should be taken in moderation to protect the body from excessive damage.
Which groups of people are susceptible to vitamin B12 deficiency?
"Tiangong Kaiwu" says: "Human life also depends on food to nourish its qi, and food is based on grain, and grain is born from soil." Those who nourish qi, not only grain, but also rely on various nutrients, among which vitamin B12 is particularly important. However, there are all kinds of people, and it is easy to lack this person for survival.
One of them is vegetarians. "The Analects of Confucius" says: "Although there is a lot of meat, it is not better than eating qi." This advises people to celebrate meat, but today's vegetarians give up the fishy smell of meat. Vitamin B12 is mostly found in animal foods, such as meat, eggs, and milk. Vegetarians eat less of this kind, and it is easy to cause its deficiency for a long time.
The second is for the elderly. The Yellow Emperor's Nei Jing says: "At the age of forty, the yin and qi are self-sufficient, and the daily life is declining." The old man's stomach is gradually weakening, and the absorption function is declining. Even if the diet is normal, the absorption of vitamin B12 by the stomach is not as good as before, so it is often on the verge of deficiency.
The third is patients with gastrointestinal diseases. Those with the stomach are affected by the valley of water, and the compound is secreted and distinct from the turbid place. If there are gastrointestinal diseases, such as enteritis, gastric ulcers, etc., their digestion and absorption can be disrupted. "On the Spleen and Stomach" says that the spleen and stomach are the foundation of the day after tomorrow, and the source of qi and blood biochemistry. Gastrointestinal diseases interfere with its transportation and
The fourth is long-term drinkers. Alcohol, the "Shang Shu" has the commandment of "indulging in alcohol, using random destruction of morality". Long-term drinking can damage the liver and stomach. Alcohol interferes with the metabolism and absorption of vitamin B12 in the body. Over time, vitamin B12 in the body gradually decreases, and eventually it is deficient.
All these groups of people should pay attention to vitamin B12 supplementation, or adjust their diet, or supplement with drugs to prevent various diseases caused by lack of this maintenance.
