Vitamin D Kids - Sunshine and Beyond

vitamin D kids

{Guest post on Love Child Organics} All this sunshine that we’ve had lately has me thinking about Vitamin D. Vitamin D’s nickname is ‘the sunshine vitamin’ because our bodies make it from exposure to the sun. However, our bodies don’t make it when we wear sunscreen. So if you’re choosing to have your kids be sun safe, you need to rely on vitamin D kids from food and supplements. Our bodies also don’t make it at the latitude of Canada or the northern United States from September through March – even on a sunny day.

Vitamin D’s Role in Our Bodies

Vitamin D is involved in building and maintaining strong bones and teeth. You’ve also likely heard about how it’s being investigated by the scientific research community for a wide variety of other roles in our bodies. While there isn’t enough evidence yet of vitamin D’s involvement in all these other roles, the research strengthens the idea that we want to make sure that babies and kids (and us adults too) get the recommended amount of vitamin D.

Here are the current recommendations:


Recommended Intake

Safe Upper Level

Birth to 6 months

400 IU


6 to 12 months

400 IU


1 – 3 years

600 IU


4 – 8 years

600 IU


9 – 70 years

600 IU


Over 70 years

800 IU


Pregnant + Breastfeeding

600 IU


Vitamin D For Babies Less Than 12 months Old

Breastmilk is naturally low in vitamin D (yes, even if you’re taking vitamin D yourself). Therefore, if you’re breastfeeding your baby, it’s recommended that you give your baby 400IU of vitamin D drops every day.

Formula does have vitamin D in it. If your baby takes 1000mL (32ounces) of formula a day then you don’t need to give your baby vitamin D drops. If your baby takes less than 1000mL (32 ounces) of formula a day (for example, if you do both breastfeeding and formula), then it’s recommended that you give your baby 400IU of vitamin D drops per day.

Vitamin D - Kids and Teens

At 12 months, the recommendations increase to 600IU of vitamin D per day. This may be from a combination of food and vitamin supplements (e.g. drops, pills, gummies).

Vitamin D in Food

Vitamin D isn’t found in many foods. I have a number of the best sources of vitamin D listed below. Note that while fluid cows milk has vitamin D in it, most yogurts and cheeses are made with cow’s milk without vitamin D in it so they aren’t sources of vitamin D. However, some yogurts are starting to be made with vitamin D fortified cow’s milk. Read the labels to find out if the yogurt you like is made with vitamin D.

While many kids are happy to drink lots and lots of glasses of milk, this usually crowds out other foods resulting in an unhealthy balance and not enough of other important nutrients (such as iron). Because of this, it’s recommended that kids drink a maximum of 2 glasses of milk a day. Goat’s milk, soy milk, almond milk, and other alternative milks may or may not have vitamin D added to them. Read the labels to find out.

Kids Vitamin D Supplements (Including Drops) 

Since sunshine and foods end up playing a small role in providing vitamin D, most kids need to continue to get vitamin D from a supplement.

The amount (i.e. number of drops) that you need to give your baby, child, or teen is different with the different types and brands of drops. Read the label on your package to find out how many drops you need.
