What did I choose for my growing niece or nephew?
I prepared supplements to look after my family’s health during Lunar New Year. For my growing niece or nephew, I chose The Day Tunteun Kids Cal-Mag Plus K2 Strawberry Flavor. I liked that it combines calcium, magnesium, vitamin D, and vitamin K2.

Since my niece or nephew is still growing, I became interested in keeping everyday nutrition balanced. When choosing a product, I looked beyond the calcium content and checked the nutrients included alongside it.

Did children like the strawberry flavor?
Even if the nutrient combination looks good, it is hard to keep up with if a child will not eat it, right? This one has a sweet strawberry flavor with almost no resistance, and I hear children reach for it first like a snack. Hearing that there was no need to force it made me glad I chose it.


What nutrients are in each sachet?
According to the product description, each sachet contains calcium, magnesium, vitamin D3, and vitamin K2. The amounts listed in the original post are calcium 220 mg, magnesium 110 mg, vitamin D 10 μg (400 IU), and vitamin K2 70 μg. I liked being able to take care of several nutrients in one sachet.

The calcium-to-magnesium ratio is 2:1. The product explains that this formulation takes calcium absorption into account. Rather than looking at the amounts alone, I was interested in which nutrients were blended together.


What did I check in the ingredient and additive information?
The ingredient information says that it uses microencapsulation technology, which makes the calcium into fine particles and then coats it once more with lecithin. I found the explanation of how the ingredients were processed impressive.

I also looked at the explanation that vitamin D3 and vitamin K2 in the trans MK-7 form are blended together. It let me check the ingredients included alongside calcium.

It also caught my eye that the origins of both the main and secondary ingredients are disclosed, and that it states no Japanese or Chinese ingredients are used. There was also a claim that it is free of five types of additives. Since it was for a child, I checked the information on ingredients and additives together.


Is the packaging easy to open, and is it simple to take?
The easy-cut type was convenient because even children with weak grip strength can open it easily.


It is a powder that melts softly in the mouth, with a sweet strawberry flavor and a clean finish without the chalky taste typical of supplements. The product description says it contains a mixed powder of seven berry concentrates. Taking one sachet a day as is or with water makes it easy to keep up with.
