Vitamin B6 for Morning Sickness
Studies suggest that taking vitamin B6 for morning sickness greatly improves nausea, though not vomiting, for many pregnant women. There has been no sign of harm to the fetus with vitamin B6 use.
A typical dose of vitamin B6 for morning sickness is 10 mg to 25 mg, 3 times a day.
Talk to your health professional before you take vitamin B6 for morning sickness.
Intake of more than 100 mg a day of vitamin B6 can cause temporary nerve damage.
