Vitamin D supplementation means giving babies vitamin D drops to support healthy bones and teeth. Breast milk contains little vitamin D, so many health authorities, including the NHS, recommend a daily supplement for breastfed babies from birth.

Key takeaways

  • The NHS recommends 8.5 to 10 micrograms a day for breastfed babies from birth to 1 year.
  • Babies having more than 500 ml of formula a day usually do not need drops, as formula is fortified.
  • Young babies should not be put in direct sunlight to get vitamin D.

What you can do

  • Give the drops daily at the dose your doctor or health authority recommends.
  • Ask your doctor about the right dose if your baby has a mix of breast milk and formula.
