Why this is the guidance
Almost any medication you take can cross the placenta, so the question is never just “does it work” but “is the benefit worth any possible effect on the baby at this stage.” Many common drugs have safer pregnancy-friendly alternatives, and the safest choice can change by trimester.
How to enjoy it safely
Prenatal Vitamins is considered a reasonable option, but “safe” still means “at the normal dose, for a real reason.” Use the lowest effective amount for the shortest time you need, and let your provider know what you're taking so it fits the rest of your care.
What about breastfeeding?
Pregnancy and breastfeeding aren't the same — some things that are limited while you're pregnant are perfectly fine once you're nursing, and occasionally the reverse is true. If you're past delivery and wondering about prenatal vitamins while breastfeeding, check with your provider, since the answer can be different from the pregnancy guidance above.
The bottom line
