At first, I looked at single-ingredient products too. Then products that could cover several ingredients at once caught my eye, and I made this product’s combination of calcium, magnesium, vitamin D, and vitamin K part of my selection criteria. ![Deodei Kalmadi product chosen for a picky eater](https://img.superchart.com/images/theday-teunteun-kids-strawberry-calcium/theday-teunteun-kids-strawberry-calcium-02-1muhe-966.webp) ![Tunteun Kids Kalmadi selected for a child’s nutritional intake](https://img.superchart.com/images/theday-teunteun-kids-strawberry-calcium/theday-teunteun-kids-strawberry-calcium-03-eeqqf-966.webp) ## What is in one daily sachet? It contains calcium, magnesium, vitamin D3, and vitamin K2. Rather than having to keep up with several separate products, it was convenient to give one sachet a day. It was easy to fit into a busy morning or right before bed. ![Deodei Kalmadi product shown with its ingredient combination](https://img.superchart.com/images/theday-teunteun-kids-strawberry-calcium/theday-teunteun-kids-strawberry-calcium-04-1wm5z-966.webp) ![Tunteun Kids Kalmadi shown with its daily serving format](https://img.superchart.com/images/theday-teunteun-kids-strawberry-calcium/theday-teunteun-kids-strawberry-calcium-05-1safj-966.webp) ![Tunteun Kids Kalmadi product shown with its multi-ingredient description](https://img.superchart.com/images/theday-teunteun-kids-strawberry-calcium/theday-teunteun-kids-strawberry-calcium-06-yaqnz-966.webp) ## What did I check about the ingredient balance and sourcing? Looking over the ingredient list, I confirmed that calcium and magnesium were blended at a 2:1 ratio. The description that the blend considered absorption was something that stood out to me while choosing a product. ![Deodei Kalmadi product introducing its calcium and magnesium blend](https://img.superchart.com/images/theday-teunteun-kids-strawberry-calcium/theday-teunteun-kids-strawberry-calcium-07-1lwuw-966.webp) ![Tunteun Kids Kalmadi shown with its ingredient blend description](https://img.superchart.com/images/theday-teunteun-kids-strawberry-calcium/theday-teunteun-kids-strawberry-calcium-08-bjywz-966.webp) Because it was something I would give my child, I also looked into where the ingredients came from. I considered the product’s description that it does not use Japanese or Chinese ingredients, as well as its use of vitamin K2 in the trans MK-7 form derived from natto bacteria culture extract. ## Did my child like the strawberry flavor and powder format? Some supplements I bought before had a medicine-like smell or a gritty texture, and my child did not eat them well. When I opened this one, it had a sweet strawberry scent, and there was very little powder scatter. ![Tunteun Kids Kalmadi shown with the strawberry flavor experience](https://img.superchart.com/images/theday-teunteun-kids-strawberry-calcium/theday-teunteun-kids-strawberry-calcium-09-n1pxa-966.webp) ![Deodei Kalmadi product introducing its strawberry scent and powder format](https://img.superchart.com/images/theday-teunteun-kids-strawberry-calcium/theday-teunteun-kids-strawberry-calcium-10-8vvq2-966.webp) It was good mixed into yogurt or allowed to dissolve in the mouth without water. My child would ask for the strawberry powder first, so there was no need to wrestle with them to get them to take it. ![Tunteun Kids Kalmadi shown with its powder serving method](https://img.superchart.com/images/theday-teunteun-kids-strawberry-calcium/theday-teunteun-kids-strawberry-calcium-11-b6o7o-966.webp) ![Strawberry-flavored Kalmadi product shown with a child’s taste experience](https://img.superchart.com/images/theday-teunteun-kids-strawberry-calcium/theday-teunteun-kids-strawberry-calcium-12-2k7cv-966.webp) I chose it after reading about the ingredient blend and sourcing, but what pleased me most after trying it was that my child took it without resistance. The one-sachet-a-day routine was convenient in everyday life too. ## Products - Deodei Tunteun Kids Kalmadi Plus K2 Strawberry Flavor — 더데이 --- Superchart · https://superchart.com/en/@matter-of-taste/theday-teunteun-kids-strawberry-calcium/ · https://superchart.com/llms.txt
