Kids’ calcium supplement morning routine: The Day Tunteun Kids
In short
The Day Tunteun Kids Kalmadi Plus K2 is a children’s calcium supplement I chose for my elementary school-age son in Korea. Its individual packets made it easy to keep up with, and he now takes it himself each morning, though I am focusing on the habit rather than noticeable changes.

Why did I start giving my elementary school-age son a calcium supplement?
My elementary school-age son usually eats well, but there are days when he rushes through breakfast before heading out. I was also concerned that he often snacks on cookies at school or at his academy. Since he has also been consistently doing jump rope and playing basketball lately, I wanted to make sure he was eating well.

To me, my son seemed smaller in height and build than other children his age. Wanting him to grow well made me pay closer attention to his usual nutrient intake.

I wanted to provide balanced meals, but preparing them every day without missing one was not easy. So I looked into a children’s calcium supplement that he could take without feeling burdened.

Which ingredients and conditions did I consider?
As I looked through several products, I first considered the ingredient combination and whether my child could take one consistently. That is how I came across The Day Tunteun Kids Kalmadi Plus K2.


Rather than choosing it based only on expectations about height, I considered whether the ingredients were ones my child needed. This product introduced calcium, magnesium, vitamin D, and vitamin K as its main ingredients.

I looked at the fact that it included magnesium and vitamin D along with calcium. I found myself looking at the combination of several ingredients rather than just one.

The inclusion of vitamin K2 also caught my attention. Still, I distinguish between why I chose it after looking at the ingredients and any changes that actually appear in my child.

How was it to keep up with every day?
Because it comes in individual packets, it was convenient to keep up with.

When choosing a product, my criteria were whether it had unnecessary additives or artificial coloring, the balance of calcium with vitamins D and K, and whether my child could take it comfortably over a long period. It felt like it met my criteria, so I have been giving it to him consistently.

Were there any noticeable changes after taking it?
There was no noticeable difference after taking it for a day or two. For now, I am focusing on establishing a routine of taking it consistently rather than looking for short-term changes.


These days, my child takes it by himself every morning. As a parent, I felt reassured seeing him take care of it himself.
