Great product

Posted by Reviewer2483880 on Aug 22, 2013

I have purchased this product repeatedly and find it to be very good and of high quality. The tablet size is average, so no huge horse pill! Just keep in mind that the tablets aren't coated so they are a little more difficult to swallow because of that. Oh, and it tastes pretty bad and bitter. But I put up with it because I like how I feel when I take it!

Love this product, I actually take it myself and give it to my dog that has had a bad shoulder, and we love it because it works, it may take a couple of weeks to see and feel a difference.
