Children

Nutrients for children in a child-friendly form: juices, drops and pastilles with vitamin D, iodine, calcium, iron and vitamin C. Vitamin D is needed for normal growth and development of bone in children. Read the guide below to see what matters at which age. Read the guide ↓

Between their first birthday and their final school exams, a child grows by a good metre.

Every centimetre needs building blocks: calcium and vitamin D for the bones, iodine for growth, iron for cognitive development. The biology is the same as it was fifty years ago, only everyday life has changed: less time at the family table, more ready meals, more screen time and hardly any sun in winter.

Here you can find out which nutrients often run low at which age, which claims the EU has authorised specifically for children and how the children's juices, drops and pastilles in our range differ.

Four stages of growth, four priorities

Children are not small adults. Up to their second birthday they grow 10 to 12 centimetres a year, and during puberty up to 10 centimetres a year once again. With every stage, the nutrients that matter most shift. Vitamin D and iodine often run low in all age groups, calcium joins them in schoolchildren and teenagers, and iron in girls from puberty onwards.

Good to know: From October to March, the sun in Austria is too low for the skin to make any real amount of vitamin D. From food alone, children get only a small part of the 20 µg that the D-A-CH reference values state for this time.

What children are missing today, what the snack box check reveals and how to recognise a child-friendly supplement is explained in detail in our blog guide What children need to grow up healthy.

Vitamin D is needed for normal growth and development of bone in children (all four). Iodine contributes to the normal growth of children, and iron contributes to normal cognitive development of children (Body Basic Omega+, Kids vitamins). Vitamin C, vitamin D and zinc contribute to the normal function of the immune system (Body Basic Omega+, Kinder-Fit, Kids vitamins).

Three myths that refuse to go away

Myth 1
“A glass of fruit juice is as good as a piece of fruit.”
Fact: Juice has lost its fibre, yet it packs the fruit sugar of several fruits into one glass. Water as the main drink and fruit to bite into make the better combination.
Myth 2
“In summer my child stocks up on vitamin D for the winter.”
Fact: The body can only store a limited amount of vitamin D. From October to March, the skin in Austria makes hardly any more, which is why many families keep vitamin D in mind all year round, especially in these months.
Myth 3
“Half an adult tablet will do just as well.”
Fact: Children need different amounts and have their own upper limits. Children's supplements are made for exactly that: with an age guideline, the right dose and a form children are happy to take.

Good to know when giving supplements

✓
Check the age guideline
Every children's supplement states the age it is intended for and how much to give. The Dr. Wunder drops are intended from 1 year, Body Basic Omega+ and Kinder-Fit from 3 years.
✓
Add up instead of doubling up
Vitamin D is often found in several products. EFSA sets the tolerable upper intake level from all sources at 50 µg a day for children aged 1 to 10 and 100 µg from 11 years. Add everything up before you combine.
✓
Make it part of breakfast
Vitamins D and K are fat-soluble and go well with a meal containing a little fat, such as bread and butter, yoghurt or muesli with milk. If you keep the bottle next to the breakfast plate, you are less likely to forget it.
✓
You measure, your child takes it
Children's supplements also belong out of the reach of children. Keep juices in the fridge once opened and check the shelf life on the label, which for Body Basic Omega+ is 4 weeks.

Kinder-Fit is the classic Cosmoterra recipe for children from 3 years, with vitamins and trace elements. Body Basic Omega+ is intended from 3 years and for the whole family, and also contains linseed oil, calcium, magnesium, iron and iodine.
My child will not swallow tablets. What are the options?+
Juices by the spoonful such as Kinder-Fit and Body Basic Omega+, drops for yoghurt or muesli, liquids to measure out such as Jodavit and Magnetovit, plus chewable tablets and pastilles to suck.
How much iodine does a child need?+
The D-A-CH reference values state 100 µg a day for children aged 1 to 3, rising to 200 µg for teenagers. Iodine contributes to the normal growth of children. Good sources are iodised salt, sea fish and dairy products.
Are there vegan supplements for children?+
Yes. Body Basic Omega+ is vegan, with its omega-3 coming from linseed oil. The Dr. Wunder D3 + K2 Kids Duo drops contain vitamin D3 from lichen.
In short
For every centimetre, children need the same building blocks as they always have, but everyday life makes it harder to get them all onto the plate. The EU has authorised claims specifically for children for vitamin D, calcium, iodine and iron. Family meals, exercise and sleep remain the foundation, and a child-friendly supplement fills the gaps in between.
KEY POINTS
  • Keep vitamin D in mind all year round.
  • Iodised salt in the kitchen, calcium above all between 10 and 18 years.
  • Child-friendly means: an age guideline, the right amount and a form your child likes.
  • Add up the amounts from all products.
