Does vitamin B6 affect the fetus

Moderate supplementation of vitamin B6 by pregnant women usually does not affect fetal health, but can help alleviate pregnancy reactions. Vitamin B6 is a water-soluble vitamin, and excessive amounts can be excreted in urine, but long-term high-dose consumption may lead to dependence or neurotoxicity. It is recommended to supplement reasonably under the guidance of a doctor and avoid self overdose. Vitamin B6 is involved in protein metabolism and nervous system function in the body, with a slightly increased demand during pregnancy. Meat, whole grains, bananas, and other foods in a normal diet can provide sufficient amounts of vitamin B6. Additional supplementation is only necessary in special situations such as severe vomiting during pregnancy. The commonly used clinical dosage is 10-25 milligrams per day, and short-term use is relatively safe. Some multivitamin preparations already contain this ingredient, so it is important to avoid repeated intake. If the daily intake of vitamin B6 exceeds 200 milligrams for a long time, it may cause abnormal development of the fetal nervous system or peripheral neuropathy in pregnant women. There have been cases reported abroad where pregnant women have been taking excessive doses of vitamin B6 for several months, leading to seizures in newborns. People with special physical conditions may have differences in their ability to metabolize vitamin B6, and genetic polymorphism may affect their conversion and utilization rates. Supplementing nutrients during pregnancy should be prioritized through a balanced diet. Foods such as animal liver, fish, and nuts are rich in vitamin B6 and have high absorption and utilization rates. When severe morning sickness occurs, vitamin B6 preparations can be taken for a short period of time under the guidance of a doctor, while monitoring the excretion of methylpyridine acid in urine. It is recommended to undergo regular prenatal check ups. If abnormal symptoms such as numbness in the hands and feet are found, seek medical attention promptly to avoid interaction with other medications.
