Vitamin B6 is an indispensable substance for cell growth and is closely related to fetal development. Generally speaking, 1 ~ 2 mg per day is enough for the fetus: if pregnant women use vitamin B6 too much, the baby will have symptoms such as excitement, crying anxiety, panic and nystagmus. If not treated in time, the baby will not gain weight within six months, and in severe cases, there will be sequelae of mental retardation.

Therefore, if pregnant women have pregnancy reaction, they must follow the doctor's advice and use vitamin B6 in moderation, and must not take it indiscriminately.
