This infant vitamin D spray delivers 400 IU (10 mcg) of **vitamin D3** per dose — exactly the daily amount pediatric guidelines (AAP and the NHS) recommend for breastfed and partially breastfed babies, who don't get enough vitamin D from breast milk alone. It's delivered as cholecalciferol (D3), the form your baby's body uses most effectively, and the spray format means you can dose a baby who can't yet swallow drops or pills by spraying directly onto the inside of the cheek.
At 400 IU, this isn't an over- or under-dose: it's the standard requirement for supporting healthy bones, developing teeth, and immune function in the first year. The one note on fit — if your baby is formula-fed and taking at least 1 litre (about 32 oz) of fortified formula a day, they may already be getting enough vitamin D, so check with your pediatrician before adding more.
