Increase the utilization rate of folic acid and promote the metabolism of carbohydrates, fats and proteins.
3. It can promote the synthesis of protein, which plays an important role in the growth and development of infants and young children. 4. Eliminate irritability, concentrate attention, enhance memory and sense of balance. 5. It is an indispensable vitamin for the sound function of the nervous system and participates in the formation of a lipoprotein in nerve tissue.
Symptoms of vitamin B12 deficiency 1. Pernicious anemia (insufficient red blood cells). 2. Irregular menstruation. 3. Yellowing of the eyes and **, local (very small) redness and swelling (no pain or itching) and accompanied by molting.
4. Nausea, loss of appetite, weight loss. 5. The lips, tongue and gums are whitish and the gums are bleeding. 6. Headache, memory loss, dementia.
7. It may cause people's mental depression. 8. Cause nucleated macrocytic anemia (pernicious anemia). 9. Deformation of the spinal cord and degeneration of nerves and peripheral nerves.
10. Inflammation of the mucous membranes of the tongue, mouth and digestive tract. 11. If there are symptoms such as loss of appetite, indigestion, inflammation of the tongue, loss of taste, etc., it is a warning sign of vitamin B12 deficiency. 12. The early manifestations of vitamin B12 deficiency in children are abnormal mental and emotional conditions, sluggish expression, less crying and less fussing, slow response, love to sleep and other symptoms, and finally cause anemia.
13. Increase the risk of heart disease. Dosage of vitamin B12 1. Intramuscular injection: 50-200 g each time, once a day or every other day.

Vitamin B12 is abundant in animal feeds and microbial fermented feeds. Vitamin B12 is a coenzyme that transports methyl groups and is involved in many metabolic processes, most importantly in the biosynthesis of nucleic acids and proteins, promotes the development and maturation of red blood cells, maintains the normal hematopoietic function of the bone marrow, and promotes the production of choline. There is no vitamin B12 in plants, but microorganisms distributed everywhere can synthesize vitamin B12 (sulfonamides and antibiotics can inhibit microbial synthesis of vitamin B12), and adult ruminants are less likely to develop B12 deficiency, and only cobalt supplementation is needed to meet the needs of vitamin B12.
Pigs and poultry often need vitamin B12 supplementation, and when deficient, protein deposition is reduced, growth retardation, anemia, dermatitis and hind limb movement is uncoordinated, and sows show reduced fertility rate. Inflammation of the musculogastric mucosa, poor growth of chicks, decreased hatchability of eggs, poor feather growth, etc.
Dosage Vitamin B12 injection is mainly used for anemia caused by deficiency and growth retardation of young animals. The specifications of the preparation are 1 ml of mg, 1 ml of mg, etc. Intramuscular injection once, 1 2 mg for horses and cattle; sheep and pig milligrams; Dogs, cats mg.

Vitamin B12 is the only vitamin that needs the help of intestinal secretions to be absorbed. Some people lack this endogenous factor due to gastrointestinal abnormalities, and even if the diet is sufficient, they will suffer from pernicious anemia. Vitamin B12 is largely absent from plant foods.
It stays in the intestine for a long time and takes about three hours to be absorbed. The main physiological function of vitamin B12 is to participate in the production of bone marrow red blood cells and prevent pernicious anemia; Prevents damage to the nerves of the brain. Vitamin B12 is the latest of the B vitamins to be discovered so far.
Vitamin B12 is a polycyclic compound containing 3-valent cobalt, and 4 reduced pyrrole rings are linked together to form 1 gooline macrocyclic ring, which is the core of the vitamin B12 molecule. Therefore, compounds containing such rings are called gogolines. Vitamin B12 is a light red needle-like crystal, soluble in water and ethanol, the most stable under the condition of weak acid at pH value, decomposed in strong acid (pH<2) or alkaline solution, it can be damaged to a certain extent when heated, but the loss of high-temperature disinfection in a short period of time is small, and it is easy to be destroyed in case of strong light or ultraviolet rays.
About 30% of the loss is lost in the ordinary cooking process.

Vitamin B12 has two main functions, the first is as a cofactor of methyltransferase, which participates in the synthesis of proteins and amino acids in the human body, so it helps the protein in our body to be biosynthesized and utilized, ensuring the normal development of infants and young children. The second is to protect the transfer and storage of folic acid within the cell. Therefore, when vitamin B12 is deficient, people are prone to folic acid-related anemia and neurological impairment associated with folate deficiency.

Vitamin B is a large family, mainly including vitamin B1 (thiamine, anti-beriberi vitamin), vitamin B2 (riboflavin), vitamin PP (nicotinic acid or niacin, anti-leprosy vitamin), vitamin B6 (pyridoxine, anti-dermatitis vitamin), pantothenic acid (pertothenic acid), biotin, folic acid, vitamin B12 (cobalamin, anti-anemia vitamin), their effects are described as follows:
1.It is a key substance in the process of glucose metabolism. The body's muscles and nerves are most susceptible to carbohydrates for energy.
If VB is sufficient, the nerve cells are full of energy, which can relieve anxiety and tension, and increase the tolerance to noise. On the contrary, it leads to a decline in the ability to cope with stress, and even neuritis.
Heart function is affected by the deposition of pyruvate and lactate. Lack of energy in the stomach and intestines, weakness of peristalsis, weakened digestive function, and constipation.
In severe cases, it can cause beriberi. Its evolution process is: weakness - tiredness - irritability, depressed mood - constipation - neuritis - heartache - heart failure - edema.
In 1897, Dutch doctors discovered that eating polished rice could cause beriberi. Mainly because of the lack of vitamin B1, so B1 is also called the anti-beriberi vitamin.
2.It is closely related to the metabolism of sugar, protein and fat. Maintain and improve the health of epithelial tissues, such as the epithelial tissues of the eyes and the mucosal tissues of the digestive tract.
In severe deficiency, there will be visual fatigue, corneal hyperemia, angular cheilitis, etc. When angular cheilitis occurs, doctors often ask people to take riboflavin, which is B2.
3.Poor fat metabolism can cause seborrheic dermatitis, acne, acne, and vitamin B supplementation has a good effect.
4.Lack of B group, resulting in weak gastrointestinal peristalsis and poor secretion of digestive juices, resulting in indigestion, constipation, bad breath, and foul stool.
The coenzyme that constitutes dehydrogenase in the body plays an important role in the metabolism of carbohydrates, proteins, and fats, and when it is severely deficient, it causes neurological, **, and digestive tract lesions, which is called leprosy and also called triple demia, which is manifested as dermatitis, diarrhea and dementia.
6.Helps body tissues use oxygen, promotes oxygen gain in nails, hair tissues, and removes or improves dandruff.
7.Removes toxins such as alcohol and nicotine, soothes headaches, migraines, and protects the liver.
The deficiency will affect the synthesis of thymine, purine, etc., causing DNA synthesis disorders. Eventually, the nucleus of red blood cells becomes immature, resulting in the formation of ineffective red blood cells, which is called megaloblastic anemia.
9.If there is a lack of folic acid in the first 3 months of pregnancy, it can lead to fetal neural tube malformations, which can increase the incidence of split encephalitis and anencephaly.
Vitamins (mainly vitamin B1) have a special smell and are the most hated vitamins for mosquitoes, so they have a certain degree of mosquito repellent effect.
