I chose this product because it was the only product that was not coated in sugar in the kids' chewable gummy vitamin section. I was pleasantly surprised that there was a variety of colours and flavours in the bottle that kept my kids interested. One day it was only green teddies and the next, only red teddies. I am not sure how EFFECTIVE the vitamin is (kids will fall sick, no matter what you do) but the acceptable sugar content and colour and flavour varieties made it easy for my kids to consume them. I'm on my third bottle now.
