What is the function of vitamin B

Vitamin B is a very important nutrient for the human body. We basically need to get vitamin B every day. It is also a very important substance for maintaining life metabolism. So what are the functions of vitamin B? Let me introduce it to you below.

All B vitamins must work at the same time, which is called the fusion effect of VB. When one type of VB is ingested alone, the activity of cells increases, thereby increasing the demand for other VBs. Therefore, the effects of various VBs are complementary, which is the so-called "barrel principle". Dr. Roger Williams pointed out that all cells have exactly the same requirements for VB.

Benefits of B vitamins

B vitamins are the key to releasing energy from food and are also essential nutrients for all human tissues. They have many common characteristics, such as they are all water-soluble vitamins that can hardly be stored in the body and must be replenished daily; they are all coenzymes and participate in the metabolism of carbohydrates, proteins, and fats in the body, and are therefore listed as a "family". Each type of B vitamin has its own characteristics and plays an important physiological role.

Common B vitamins

Vitamin B1

Vitamin B1, also known as thiamine, constitutes a coenzyme, maintains normal metabolism in the body, promotes gastrointestinal motility, and maintains the normal functions of the nervous and circulatory systems.

Vitamin B1 deficiency can cause slow gastrointestinal motility and loss of appetite; beriberi is manifested by weakness in the lower limbs, muscle aches, anorexia, constipation, etc., and is accompanied by neurological symptoms such as fatigue, headache, insomnia, restlessness, irritability, depression, and forgetfulness.

Vitamin B2

Vitamin B2, also known as riboflavin, participates in energy metabolism in the body as a coenzyme and is closely related to the antioxidant defense system. It plays an important role in promoting normal growth and development and maintaining the integrity of the skin and mucous membranes.

Common symptoms of vitamin B2 deficiency include chapped lips, angular cheilitis, glossitis, edema and congestion of the oral mucosa, seborrheic dermatitis of the nose and face, and inflammation of the skin around the mouth and vulva; eye symptoms include blepharitis, photophobia, tearing, blurred vision, and even immunodeficiency and fetal malformations.

Vitamin B6

Vitamin B6 participates in all amino acid metabolism as a coenzyme, and plays an important role in the synthesis of neurotransmitters and hemoglobin, and homocysteine ​​metabolism.

Vitamin B6 deficiency can lead to fatigue, insomnia, stomatitis, seborrheic dermatitis and certain neuropsychiatric symptoms; damage DNA synthesis and affect immune function. Vitamin B6 deficiency will also increase the level of homocysteine ​​in plasma, increasing the risk of chronic diseases such as fatty liver and hyperlipidemia; and vitamin B6 also plays an important role in growth and cognitive development.

Vitamin B12

Vitamin B12 can promote DNA synthesis in red blood cells and prevent megaloblastic anemia; it participates in the metabolism of homocysteine, helps to lower the level of homocysteine ​​in the blood, thereby preventing cardiovascular and cerebrovascular diseases.
