They are quite good.
Item Package Quantity: 1
I used to take flintstone chewable vitamins ( yes I’m an adult, but I prefer chewable vitamins). I don’t like the way they get so discolored before I can use the whole bottle. Decided to try these. The formula is a bit different, but sufficient for me. I actually found I like them a lot. Yes they ate all orange flavored, but quite nice. A bit softer than the others, and smaller. I think these will be my go to vitamins now.
