B vitamins are a group of water-soluble vitamins, including vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B3 (niacin), vitamin B5 (pantothenic acid), vitamin B6 (pyridoxine), biotin (vitamin B7), folic acid (vitamin B9), and vitamin B12, etc. They play important roles in the human body and a deficiency of B vitamins can lead to various health problems. 

B vitamins, as a crucial group of nutrients in the human body, the consequences of their deficiency should not be underestimated. When there is a lack of B vitamins, the body will send out a series of warning signals.
01. Affecting skin and oral health

Firstly, skin problems become the primary victims. A deficiency in B vitamins, especially vitamin B2 and vitamin B6, can lead to dry skin, peeling, and even seborrheic dermatitis. Additionally, oral health is also affected, such as oral ulcers and cheilitis, all of which are related to the insufficient intake of vitamin B2 and B12.

02. Affecting nervous system health

Secondly, the nervous system is also affected. A deficiency in vitamin B1 (thiamine) can cause beriberi, characterized by numbness in the limbs and muscle weakness. In severe cases, it can even affect the heart function. A deficiency in vitamin B12 can lead to anemia, accompanied by fatigue, dizziness, and an increased risk of neurological diseases, such as peripheral neuropathy.
03. Affecting digestive system health

In addition, the deficiency of B vitamins may also affect the digestive system, leading to symptoms such as loss of appetite and indigestion. A lack of vitamin B3 (niacin) can cause pellagra, characterized by rough skin and diarrhea.
At the same time, the deficiency of vitamin B6 is also associated with weakened immune function, mood swings, and other issues. Long-term lack of B vitamins may also increase the risk of chronic diseases such as cardiovascular diseases and diabetes. Therefore, maintaining adequate intake of B vitamins is crucial for maintaining good health.

The functions and effects of the B vitamins are as follows:
