Why did I start giving calcium-magnesium to my five-year-old?
When my child turned five, they moved to a new daycare. I worried about whether they would adjust well after leaving a familiar place, so I paid closer attention to their usual meals and basic nutrition.



It was also a busy period for me, going back and forth between work and home while preparations for enrollment and graduation overlapped. I thought my child would feel nervous about the unfamiliar environment too, which made me want to take even better care of them.



The product I started giving them then was The Day Tunteun Kids Calcium Magnesium Plus K2. In the mornings, I had to handle my child's meal and get ready for work, so it mattered that it would be easy to manage even in a busy routine.

When I spoke with parents of children the same age who were also changing daycares, we had similar concerns about adjustment. I looked at the product's composition because I wanted to support my child's bone health and basic nutrition.

What did I look for in the ingredients and materials?
I noticed that each sachet contained calcium, magnesium, vitamin D3, and vitamin K2. I also considered the product's stated 2:1 blend ratio and four functional claims when choosing it.



Since it was a product for my child, I also checked the information about the ingredients. I liked the guidance stating that it did not include ingredients from Japan or China, as well as the explanation that it uses vitamin K2 in trans MK-7 form.

Did my child take it well, and was it easy to manage?
After work, I picked up my child, gave them dinner, and then gave it to them. When I suggested having the pink product, my child liked it enough that they now took it on their own.


My child held the product tightly in their hand and took it well. One sachet a day was convenient for me during busy days, and I liked how willing my child was to take it on their own.
