One stick pack a day provides calcium, magnesium, vitamin D3, and vitamin K2 together. When I had to keep track of several supplements separately for my child, it was easy to miss one, so being able to cover them in one pack made things easier to manage.

My child will not take a supplement if they do not like its flavor or texture. Because of that, there have been plenty of supplements we threw away or that I ended up taking instead.
