Morning sickness

It's as much a part of pregnancy as painting the nursery

Vitamin B6 can help treat pregnancy-related nausea and vomiting1,2

Nausea and vomiting are common in early pregnancy, affecting 70% to 85% of moms-to-be.1 Treatment of morning sickness symptoms in the early stages can be beneficial in supporting a healthy pregnancy.2

Vitamin B6 can help treat pregnancy-related nausea and vomiting,1,2 and is recommended by the American Congress of Obstetricians and Gynecologists (ACOG) as a safe and effective first-line treatment for pregnancy-related nausea and vomiting.2

PreferaOB ONE® has the vitamin B6 found in other prenatal vitamins—and then some.

Most prenatal vitamins contain vitamin B6, but it may not be in high enough concentrations to address the morning sickness you may experience. The 50-mg dose of vitamin B6 found in PreferaOB ONE® is one of the highest doses available in a prenatal vitamin, and can help treat pregnancy-related nausea and vomiting.1,2

Vitamin B6 is good for you—and it's essential for your baby

For all it does to help treat your morning sickness, vitamin B6 is even more important in your baby's development, playing a key role in3:

  • Normal physiological function
  • Supporting macronutrient (fat, proteins, and starches) metabolism
  • Red blood cell, antibody, and neurotransmitter synthesis

For this reason, it is also vital to fetal brain and nervous system development.4 The vitamin B6 in PreferaOB ONE® helps ensure mom and baby are provided for.1,2
