Does my baby need vitamin D drops?
Last updated October 5, 2026
If your baby is breastfed, NHS guidance recommends vitamin D drops from birth. For formula-fed babies, the recommendation depends on daily formula intake. For vitamin D, the recommended range of 8.5–10 micrograms narrows to 10 micrograms from age 1. Below are those UK recommendations and a checklist for the bottle you have at home.

Does feeding type change whether drops are needed?
Yes. The NHS distinguishes breastfed babies from babies taking more than 500ml of infant formula a day, because formula already contains vitamin D. For babies under one year, use this table to identify the recommendation or the question to take to your health visitor.
| Your baby's feeding | NHS guidance or next step |
|---|---|
| Breastfed, without infant formula | Daily vitamin D supplement from birth, containing 8.5–10 micrograms |
| Formula-fed, more than 500ml a day | Vitamin D supplements are not recommended while intake stays above 500ml; check again if feeds change, for example during weaning |
| Formula-fed, less than 500ml a day | Daily supplement containing 8.5–10 micrograms, throughout the year |
| Mixed feeding, or formula intake at or near 500ml a day | Ask your health visitor how the guidance applies to your baby's feeding |
The NHS recommends a supplement for breastfed babies and for formula-fed babies having less than 500ml a day. The formula exception applies only above 500ml.
Both NHS pages (vitamins for children and vitamin D) say “more than 500ml” for the formula exception and “less than 500ml” for supplementation, so a baby on exactly 500ml falls between them. Ask your health visitor rather than picking a rule from the table, and take your baby's age and formula intake with you, especially if feeds have changed during weaning.
How much vitamin D is recommended at each age?
The NHS recommends 8.5–10 micrograms daily for babies under one who need a supplement, and 10 micrograms daily throughout the year for children aged 1–4. NHS: vitamin D
Labels may show micrograms as µg or mcg, or use international units (IU). The NHS gives the conversion as 1 microgram = 40 IU, so 10 micrograms = 400 IU. That is an amount of vitamin D, not a number of drops. If a label says 400 IU per dose, that dose contains 10 micrograms. Use your product's label to check the dose; ask a pharmacist if the units or instructions are unclear. NHS: vitamin D
The NHS also recommends daily vitamins A, C and D for children aged 6 months to 5 years, with an exception for babies having more than 500ml of infant formula a day. The NHS says one supplement on its own is enough, as long as it contains the recommended dose of vitamin D, so the aim is one product that supplies the vitamin D amount, not stopping vitamin D. Ask a pharmacist which supplement suits your child's age and feeding. NHS: vitamins for children
If you are thinking of changing products when your baby reaches six months, ask a pharmacist first. The NHS advises against giving two supplements at the same time. NHS: vitamins for children
What should you check before giving the drops you bought?
Follow the label and leaflet for the actual product you are using, and ask a pharmacist to explain any unclear instructions. The NHS advises keeping to the label dose and avoiding two supplements at the same time. NHS: vitamins for children
Before your next pharmacy visit, note:
- Your child's age, feeding pattern and daily formula intake.
- The product name, its vitamin D amount per stated dose, and its instructions.
- Any other vitamin products your child is already taking.
Bring the bottle or a photograph of its label. If drops were missed, spilled or vomited, ask the pharmacist about that product before deciding what to do. If your child has a prescribed supplement plan, check changes with the team that gave you that plan.
Can food replace the recommended supplement?
The NHS says it is difficult to get enough vitamin D from food alone, and recommends that young children still have vitamin drops even when they spend time outdoors. Oily fish such as salmon and egg yolks are food sources, but choosing a meal does not change the supplement recommendation above. NHS: vitamins for children and NHS: vitamin D
For first-food choices, see iron-rich first foods. If you are starting baby-led weaning, keep the supplement question on your list for your health visitor.
Can you get vitamin drops free?
Families who qualify for Healthy Start can get free vitamin drops, according to the NHS. Ask your health visitor where to get them; the Healthy Start programme explains who qualifies. NHS: vitamins for children
