Why did I choose a children’s calcium-magnesium supplement?
Once my child turned two, I started paying closer attention to nutrients such as calcium and vitamin D alongside meals. I was drawn to something I could fit into a busy day without making things complicated.

A mom around me recommended The Day Tunteun Kids Cal-Mag Plus K2 Strawberry Flavor, which is how I found it. This time, I received the product and added it to my child’s nutrition routine.

What was taking one sachet a day like?
Each sachet contained calcium, magnesium, vitamin D3, and vitamin K2. Being able to take care of it with one sachet a day meant less hassle than preparing several different products separately.


Mornings are hectic and I am tired by evening, so I really value a nutrition routine for my child that is not complicated. This one had such a simple process that I reached for it often.


What did I look at in the ingredient formula?
The information saying that calcium and magnesium were formulated at a 2:1 ratio caught my eye. Along with whether calcium was included, I also looked at how the magnesium was formulated.


I was also interested in the fact that it contained both vitamin D3 and vitamin K2. The product information says the vitamin K2 ingredient is in trans MK-7 form.

What I liked was the formula that lets me cover magnesium and two vitamins along with calcium.


What did I check in the ingredient information?
Since this is something I give my child, I also looked at the explanation of where the ingredients came from. The information said it does not use Japanese- or Chinese-sourced ingredients and uses ingredients from global ingredient suppliers, and that kind of sourcing explanation matters to me.

Did my child like the strawberry flavor?
When choosing supplements for my child, I think it is important whether my child will actually take them well. This one was strawberry flavored, and my child liked it.
What stayed with me most was a flavor my child enjoyed and the convenience of one sachet a day. It felt like less of a burden within our everyday parenting routine.
