[EX Q]: We have been giving our 100 pound shepherd/lab/collie/husky mix Hip Action since he was a pup. Our vet believes this is realy going to help him prevent all the hip problems that shepherd's usually have. Eventhough I cannot buy it locally, I make sure to buy it on line so my boy will remain healthy and happy!
[EX A]: Negative

[EX Q]: I decided to purchase this product based on a blog by one of the supplement oriented doctors on the internet, hyping erythritol as superior to xylitol, which I use regularly and find the closest to sugar in taste with almost no aftertaste and no side effects to my knowledge. The problem I find with erythritol is its lack of flavor. On cereal, I barely notice any real sweetness, even when I put as much as a tablespoon and a half on a normal size bowl. When I use Ideal, the name of the xylitol brand I use, it has the same sweetness as sugar in the same proportion. Don't get me wrong, erythritol isn't unpleasant, it just has very little sweetness relative to how much you use. Not worth the price unless you want just a hint of sweetness compared to what you get with sugar or xylitol.
[EX A]: Negative

[EX Q]: My grandma buy these HUGE plastic bins full of Folders ground coffee. Puroast tastes like the very last pot she makes from a plastic bin - weak, stale and bitter. My daughter is coffee connoiseur, so I gave her a cup, she took a sip and asked me where I managed to find such low quality coffee. Going wihout coffee is better than drinking this.
