The main vitamins that nourish the brain nerves include vitamin B1, vitamin B12, niacin, folic acid, etc., all of which have good nutritional effects on the nervous system. If a patient lacks these vitamins, the patient’s nervous system may develop abnormally and develop neurological disorders. In particular, a lack of folic acid during fetal life can affect the development of the nervous system and lead to neurological disorders such as spina bifida and cerebral palsy. Therefore, supplementation with essential vitamins is still very important for human health and for maintaining normal physiological functions of a person. Vitamin supplementation should be a dietary supplement, with more vitamin-rich foods such as fresh fruits and vegetables, but medications should also be considered to supplement the appropriate vitamins when necessary.
