Three of 12 are on a testing list, and six give 400 IU in one drop
We checked 12 vitamin D drops for babies sold on Amazon. Three are on a third-party testing list, all NSF/ANSI 173: Ddrops in both sizes and Mommy’s Bliss. Six give 400 IU in a single drop: both Ddrops, Mommy’s Bliss, Carlson’s 365-drop and 90-drop bottles, and Dr. Green Mom. Nine hold only D3 and an oil; Enfamil, ChildLife Essentials and Dr. Green Mom add more (water and glycerin, berry flavor, or vitamin K2).
Here are 8 in two groups, our pick first, each group from lowest cost a month. The rest are not on a testing list.
We also read Carlson’s 90-drop bottle, Dr. Green Mom D3 + K2 drops, ChildLife Essentials berry drops and Live Wise Naturals organic drops.

The AAP says 400 IU a day, starting soon after birth
The American Academy of Pediatrics says breastfed babies need extra vitamin D, 400 IU (10 mcg) a day until age one. That covers partly breastfed babies too: the AAP leaves out only babies who drink more than 27 ounces of formula a day. Its policy statement says to start soon after birth (Wagner, 2008). The NIH gives the same 400 IU for birth to 12 months.
Look for D3, 400 IU in one dose, and few ingredients
- Vitamin D3 (cholecalciferol). All 12 we checked use it.
- 400 IU in one drop, so there is nothing to measure. Six of 12 do it.
- Only D3 and an oil. Nine of 12 keep it that simple.
- A dispenser you can use one-handed: a dropper bottle that gives one drop, or a syringe or dropper marked for the dose.
Ddrops’ label says to put the drop on your nipple; Mommy’s Bliss says to mix it into milk or food
The two labels
How to give the drops: follow your bottle’s label
- Ddrops: “Place 1 drop daily onto mother’s nipple or on a clean surface, such as a washed finger, and allow baby to suck for at least 30 seconds. Or mix one drop daily with milk, juice or other food.”
- Mommy’s Bliss: “May be mixed into formula, breast milk, juice, or other foods.” Its label says not to give it straight into the baby’s mouth.
- Zarbee’s: “Deliver 0.25 ml by dropper into mouth or mixed with food or drink.”
- Nordic Naturals: “Using dropper measure 0.25 mL. Add to food, breast milk, or infant formula once daily.”
- Enfamil: “Dispense gently into mouth towards inner cheek,” or mix it with breast milk, formula or food.
Give one dose, once a day, and one vitamin D product at a time. The NIH’s upper limit for babies up to 6 months is 1,000 IU a day from all sources.
Questions people ask
Do breastfed babies need vitamin D drops?
Yes. The NIH says breast milk alone does not give a baby enough vitamin D, and that breastfed babies should get 400 IU (10 mcg) a day.
When should my baby start vitamin D drops?
Soon after birth. The AAP’s policy statement says babies should get 400 IU a day beginning soon after birth (Wagner, 2008).
Does my baby need drops if they also get formula?
Yes, unless your baby drinks more than 27 ounces of formula a day. The AAP gives that as the only exception for babies who get some formula.
Is one drop of Ddrops enough?
Yes. One drop holds 400 IU (10 mcg), the full daily amount for a baby under one.
How much vitamin D should I take while breastfeeding?
The NIH’s daily amount for breastfeeding women is 600 IU (15 mcg). See the best vitamin D supplements for adults. After your baby’s first birthday, the AAP amount for the child rises to 600 IU; more in our vitamin D dosage guide.
