[EX Q]: What I liked the most about using these Gelatin Vitamins was how quickly my nails started to grow and the strength of them. I always have had thin and brittle nails but now they are finally starting to harden. I also started noticing how much my skin has cleared up on face!
[EX A]: positive

[EX Q]: I have been buying these candies for years and years, and now it is so convenient to buy them online. Great flavors. Love that the cinnamon has a "little burn" to it.
[EX A]: positive

[EX Q]: My puppies shed like crazy! These allowed us to go outside and pet them for a half an hour and they love it and we create quite the tumble weed of dog fur. Much less intimidating for the dogs and much easier to use for us. No need to keep pulling off like a traditional brush
[EX A]:
positive
