Many pregnant women experience nausea during the first trimester. This is commonly referred to as "morning sickness," though it can occur at any time of the day. Mild morning sickness may affect up to 85 percent of pregnant woman. There is some evidence that taking B6 supplements may reduce morning sickness. Do not take any supplements during pregnancy without the advice of your doctor.
What is Vitamin B6?
The B vitamins help convert the food you eat into fuel for your body. Vitamin B6 is also called pyridoxine, and it helps your body manufacture hormones that influence your moods and regulate your internal clock. Having adequate levels might reduce your risk of developing heart disease and depression. You can take it as an individual supplement, as part of a multivitamin or in a B-complex vitamin. Dietary sources include poultry, fatty fish, dairy products and whole grains.
Will Vitamin B6 Help?
According to the American Congress of Obstetricians and Gynecologists, taking vitamin B6, with or without the antihistamine doxylamine, is a safe and effective way to reduce your morning sickness. Pregnant women need a minimum of 1.9 mg of vitamin B6 daily, and taking a 50-mg supplement can make you feel better during your first trimester of pregnancy. If you are vomiting constantly, talk to your doctor because you may have a more severe form of morning sickness called "hyperemesis gravidarum."
Other Remedies
In addition to taking vitamin B6 supplements, you can make lifestyle changes that may reduce your morning sickness. Eat small meals often, instead of three large meals per day. Keep a dry, bland snack, such as crackers or dry cereal, near your bed, and eat a small amount before getting out of bed in the morning. Rest often, and take steps to avoid foods and odors that make your nausea worse. Drink liquids to avoid dehydration, but avoid drinking at the same time that you are eating.
Warnings
Always tell your health care provider about any supplements or medications that you take during pregnancy. Do not take more than 100 mg of vitamin B6 without your doctor's supervision. Large doses, over 200 mg daily, can cause neurological problems that may persist for up to six months. Some people have reported an allergic reaction to vitamin B6; if you notice a skin rash while taking this supplement, discontinue it and contact your doctor. Certain medications, including some used for asthma, high blood pressure, depression or infections, may interact with this vitamin.
