Is Vitamin D safe in pregnancy?
Generally safe
Yes — 10 micrograms (400 IU) daily throughout pregnancy.
What the evidence says
Vitamin D is actively recommended in pregnancy. The NHS advises 10 micrograms (400 IU) daily, year-round, for all pregnant and breastfeeding women. Many pregnancy multivitamins include this amount.
Why this matters
Vitamin D supports the baby’s bone and tooth development. Most UK adults are insufficient in vitamin D for part of the year.
