Why it matters
Vitamin D is the nutrient children run short on first.
Half the year without sun
Between autumn and early spring the sun sits too low in Europe for skin to synthesise vitamin D — whatever the weather does.
Immunity, bones, teeth
Vitamin D contributes to the normal function of the immune system in children and to normal growth and development of their bones and teeth.
Food rarely covers it
Oily fish and egg yolks are the main dietary sources. Most children eat them a few times a month, not a few times a week.
The quiz
Where does your child stand?
Six questions, about two minutes. No email needed — your result appears straight away.
Vitamin D check for children
We ask about your child's age, time outdoors, diet and any signs you may have noticed — then show a clear result with an age-appropriate daily dose.
Informational only — not a medical diagnosis.
How old is your child?
This sets the dose we recommend at the end.
On a normal day, how long is your child outdoors?
Skin needs uncovered time in daylight to make vitamin D.
How strong is the sun where you live right now?
Season and latitude decide whether the sun can help at all.
How often does your child eat oily fish or egg yolks?
Salmon, mackerel, sardines, herring or eggs.
Does your child take vitamin D now?
Drops, spray or a children's multivitamin containing D3.
Have you noticed any of these lately?
One infection after another, unusual tiredness, restless sleep, leg or growing pains.
Your result · likely running low
Your child is very likely short on vitamin D
Little daylight, weak sun and a diet without much oily fish is the combination behind most children's deficiency — and nothing in that situation fills the gap on its own. A daily supplement through the whole low-sun season is the simplest fix, ideally with vitamin K2 alongside so calcium ends up in bones and teeth.
Your result · gaps to close
Your child is getting by — with gaps
Some of the basics are in place, but the supply is uneven: sunny weeks and outdoor days help, then a stretch of grey weather or a break in supplementation undoes it. Keeping a steady daily dose is what turns "sometimes enough" into consistently enough.
Your result · in good shape
Vitamin D looks well covered
Plenty of daylight, fish on the plate and a supplement in place — keep it going, especially once the sun gets lower. The nutrient most children in your situation still miss is omega-3 DHA, which works alongside vitamin D for the brain, eyes and immune system.

This quiz gives general guidance based on your answers and is not a medical diagnosis. A blood test is the only way to confirm vitamin D status — if symptoms persist, speak to your paediatrician. Food supplements do not replace a varied diet.

Good to know
Vitamin D for children, answered
Still unsure after the quiz? These are the questions parents ask us most.
When should children take vitamin D?
In most of Europe, supplementation is usually recommended through the low-sun months — roughly October to March — and year round for babies. If your child spends most days indoors, the whole year is worth considering.
Why combine D3 with K2?
Vitamin D helps the body absorb calcium; vitamin K2 helps direct it towards bones and teeth. That is why our Kids Omega 3 + D3/K2 and the family Vitamin D3 + K2, 1000 IU D3 / 25μg K2-MK7 pair the two.
Which is right — drops with omega-3 or plain D3?
If your child eats little oily fish, Kids Omega 3 + D3/K2 covers D3, K2 and DHA in a single daily millilitre. If omega-3 is already handled, Kids Vitamin D3 from €11,99 is the simple, low-cost choice.
Is it suitable for babies?
Kids Vitamin D3 is formulated for the youngest children from 6 months — one drop provides 400 IU. Follow the dosage on the label and ask your paediatrician if your child takes other supplements.
Can the quiz replace a blood test?
No. It maps the everyday factors behind most deficiency — daylight, season, diet, supplementation — so you can act sensibly. Only a 25(OH)D blood test measures actual status.
