Vitamin B group is one of the essential nutrients to maintain the normal function of human beings. Vitamin B includes Vitamin B1, vitamin B2, vitamin B6, vitamin B12, nicotinic acid, pantothenic acid, folic acid, etc. So, when the body lacks B vitamins, what symptoms will appear? Let's take a look today.

1. Decreased immunity

Vitamin B2, in the form of coenzymes, participates in many metabolic redox reactions and plays a role in energy production in the cellular respiratory chain. Seborrheic dermatitis, epithelial keratosis, seborrheic alopecia and neurological disorders may occur in the absence of seborrheic dermatitis, resulting in impaired metabolism of energy, amino acids and lipids, which can seriously lead to low immune function.

2. have beriberi

Vitamin B1 mainly maintains normal metabolism in vivo, inhibits the activity of cholinesterase, promotes gastrointestinal peristalsis and the role of nerve tissue. If lacking, beriberi is the most common disease.

3. anemia

Vitamin B6 is involved in the metabolism of neurotransmitters, heme, steroids, nucleic acid, glycogen and sphingomyelin, and amino acid metabolism. It has the function of maintaining immune function, nervous system function and reducing homocysteine. Deficiency can lead to typical seborrheic dermatitis, depression, anemia, etc. Vitamin B12, in the form of coenzyme, plays a physiological role in the body, participates in the body's biochemical reactions, lacking common vegetarians, will manifest as erythrocyte anemia and hyperhomocysteinemia.

4. Easily fatigued

Nicotinic acid, namely vitamin PP and nicotinic acid, mainly exists in various tissues of the body in the form of coenzymes. It is a component of the glucose tolerance factor. It protects the cardiovascular system. Lack of nicotinic acid can cause skin diseases, such as weight loss, fatigue and fatigue, poor memory and insomnia.

These are the manifestations of vitamin B deficiency. In life, if the body has these manifestations, it should pay attention to, because it may be lack of vitamin B, we should pay attention to vitamin B supplementation.
