I love these and repeat buy these for my kids, they are fast dissolve and easily chewable. the citrus flavor is great too, not too strong but just enough and not tart either. kinda more like Orange flavored. kids will not eat other flavors you would think they would like, lol. my only complaint is they dont put enough of the cotton packing to keep them from crushing so there is sometimes alot of powder at the bottom. They also work within like 30-40 minutes, i give them to my kids at bed time and winthin the hour they fall asleep. definitely recommend.
