Of the various products I have given my child, they took this one especially well and liked it enough to try to have two or three more a day. ![The Day Cal-Mag-D strawberry product given to my child](https://img.superchart.com/images/theday-kids-calcium-strawberry-powder/theday-kids-calcium-strawberry-powder-02-vk86f-900.webp) ![The Day Tunteunki즈 Cal-Mag-D strawberry product](https://img.superchart.com/images/theday-kids-calcium-strawberry-powder/theday-kids-calcium-strawberry-powder-03-185wd-900.webp) ## Were the individual packets easy to open and take? When I first opened the delivery box, the red packaging caught my eye. Its design brought strawberries to mind, and my child was curious about it too. ![Cal-Mag-D Plus and Strong multivitamin products](https://img.superchart.com/images/theday-kids-calcium-strawberry-powder/theday-kids-calcium-strawberry-powder-04-chpsf-900.webp) *Cal-Mag-D Plus is on the right, and the Strong multivitamin introduced alongside it is on the left.* ![Cal-Mag-D packaging reminiscent of strawberry flavor](https://img.superchart.com/images/theday-kids-calcium-strawberry-powder/theday-kids-calcium-strawberry-powder-05-1qhlw-900.webp) ![Red packaging of The Day Cal-Mag-D strawberry flavor](https://img.superchart.com/images/theday-kids-calcium-strawberry-powder/theday-kids-calcium-strawberry-powder-06-fnevs-900.webp) It comes in individual packets with easy-cut notches, so I could tear them open by hand without scissors. I also liked the condition and finish of the packaging, and I could check the nutrition information on the back of the box. ![Nutrition facts panel on The Day Cal-Mag-D packaging](https://img.superchart.com/images/theday-kids-calcium-strawberry-powder/theday-kids-calcium-strawberry-powder-07-113ye-900.webp) *The nutrition facts panel on the back of the product.* ![The Day Cal-Mag-D product information from the official website](https://img.superchart.com/images/theday-kids-calcium-strawberry-powder/theday-kids-calcium-strawberry-powder-08-12mqg-900.webp) *Source: official website product-detail description.* ## What did I check when choosing the ingredients? When choosing supplements, I tend to look at the country of origin of the ingredients first. The information saying that this product does not use Japanese or Chinese ingredients had a major influence on my choice. ![Information about The Day Cal-Mag-D ingredients](https://img.superchart.com/images/theday-kids-calcium-strawberry-powder/theday-kids-calcium-strawberry-powder-09-6zixw-900.webp) *A Cal-Mag-D product whose ingredients I reviewed.* ![The Day Cal-Mag-D with ingredient origins reviewed](https://img.superchart.com/images/theday-kids-calcium-strawberry-powder/theday-kids-calcium-strawberry-powder-10-rpplt-900.webp) Because it was a product for my child, I also checked the statement that no coloring was added. The information about ingredients and additives matched the criteria I consider important when choosing a product. ![Cal-Mag-D introduced with additive information](https://img.superchart.com/images/theday-kids-calcium-strawberry-powder/theday-kids-calcium-strawberry-powder-11-1s5gc-900.webp) When I tried it myself, the powder particles felt fine and consistent. I also liked that it did not clump in the mouth and melted softly. ![The Day Cal-Mag-D product description from the official seller](https://img.superchart.com/images/theday-kids-calcium-strawberry-powder/theday-kids-calcium-strawberry-powder-12-qy4hc-900.webp) *Source: The Day Cal-Mag-D official seller.* ## Which nutrients does it contain? The product description presents it as a product with four functional ingredients: calcium, magnesium, vitamin D3, and vitamin K2. I also checked the information that the calcium-to-magnesium ratio is 2:1 and that the vitamin K2 is in Trans MK-7 form. ![Cal-Mag-D ingredient information from The Day official seller](https://img.superchart.com/images/theday-kids-calcium-strawberry-powder/theday-kids-calcium-strawberry-powder-13-1ealu-900.webp) *Source: The Day official seller.* ![Information on calcium and magnesium formulation in Cal-Mag-D](https://img.superchart.com/images/theday-kids-calcium-strawberry-powder/theday-kids-calcium-strawberry-powder-14-9qqkx-900.webp) *I reviewed the calcium-to-magnesium formulation ratio.* I liked having several ingredients in one packet. I thought it would be more convenient than giving separate products one by one. ![Cal-Mag-D product introduced with its nutrient combination](https://img.superchart.com/images/theday-kids-calcium-strawberry-powder/theday-kids-calcium-strawberry-powder-15-1qe8k-900.webp) ![The Day Tunteunki즈 Cal-Mag-D product introduction](https://img.superchart.com/images/theday-kids-calcium-strawberry-powder/theday-kids-calcium-strawberry-powder-16-8ufw6-900.webp) ## Did my child like the strawberry flavor and powder format? To my taste, it was closer to a mild, sweet strawberry flavor than an artificial syrup taste. My child would ask first, saying, “Please give me strawberry powder!” Although it is a powder, it melted softly in the mouth and was easy for my child to take. ![Cal-Mag-D introduced with strawberry flavor experience](https://img.superchart.com/images/theday-kids-calcium-strawberry-powder/theday-kids-calcium-strawberry-powder-17-z5f3e-900.webp) ![Cal-Mag-D introduced with powder-format experience](https://img.superchart.com/images/theday-kids-calcium-strawberry-powder/theday-kids-calcium-strawberry-powder-18-10vrd-900.webp) In our home, not only my child but also my spouse and I took it. The two of us had two packets a day, which was simply how we used it at home. ## Why would I buy it again? What satisfied me most was that my child did not refuse it and instead asked for it first. I would consider buying it again because I also liked the hand-tearable individual packets and the combination of several nutrients. ![The Day Cal-Mag-D product tried by the family](https://img.superchart.com/images/theday-kids-calcium-strawberry-powder/theday-kids-calcium-strawberry-powder-19-1xc0r-900.webp) ![Cal-Mag-D introduced with repurchase thoughts](https://img.superchart.com/images/theday-kids-calcium-strawberry-powder/theday-kids-calcium-strawberry-powder-20-1liw8-900.webp) ## Products - The Day Tunteunki즈 Cal-Mag-D Plus K2 Strawberry Flavor — 더데이 - 더데이 공식 브랜드 스토어 — 온라인 구매 --- Superchart · https://superchart.com/en/@kettle-and-key/theday-kids-calcium-strawberry-powder-58ce/ · https://superchart.com/llms.txt
