Why did I choose a calcium-magnesium supplement for kids?
Once my child turned two, I started paying closer attention to nutrients such as calcium and vitamin D alongside meals. I was interested in something I could incorporate without making our busy routine complicated.
I learned about The Day Tunteun Kids Cal-Mag-D Plus K2 Strawberry Flavor through a recommendation from another mom. This time, I received the product and added it to my child’s nutrition routine.
How was the one-sachet-a-day routine?
Each sachet contained calcium, magnesium, vitamin D3, and vitamin K2. Having one sachet a day reduced the hassle of preparing several different supplements separately.
Mornings are hectic and I am tired in the evenings, so I care about whether my child’s nutrition routine is uncomplicated. This product was simple to prepare, so I reached for it often.
What did I look at in the ingredient formula?
The information saying calcium and magnesium were blended in a 2:1 ratio caught my attention. Along with whether it contained calcium, I also looked at how the magnesium was included.
I was also interested that it contained vitamin D3 and vitamin K2 together. The product information said the vitamin K2 used a trans MK-7 form ingredient.
What I liked was the formula that let me include magnesium and two vitamins alongside calcium.
What did I check in the ingredient information?
Because it was a product for my child, I also looked at the explanation of ingredient origins. It said it did not use ingredients from Japan or China and instead used ingredients from global ingredient companies; I was interested in that kind of sourcing information.
Did my child like the strawberry flavor?
When choosing supplements for my child, I also consider whether they will actually take them well. This one was strawberry-flavored, and my child liked it.
What stayed with me most was the flavor my child liked and the convenience of one sachet a day. It felt less burdensome within our everyday childcare routine.
