Why do I need thiamine?
Thiamine, also known as vitamin B1, converts carbohydrates into energy for both mother and baby essential for your baby's brain development. It also aids the normal functioning of the nervous system and the heart. If a pregnant woman is thiamine-deficient, her infant is at risk for beriberi, a serious heart ailment.
How much do I need?
You need a third more thiamine when you're pregnant, from an RDA (recommended daily allowance) of 1.1 mg up to 1.5 mg. If you're nursing, you'll need a bit more, 1.6 mg.
Should I take a supplement?
Chances are you'll get enough thiamine by eating well, but a good multivitamin will supply you with most of your recommended daily allowance.
