Smartship is the way to go. When I first switched to the Glycanaid HA and saw how my dog was acting like a puppy again I knew he would be staying on the supplement. I signed up for smartship so I wouldn’t have to remember to order it. I have a large pit bull (85 lbs) who has had both CCL’s surgically repaired. He’s happier and more active than he was before I switched to the Glycanaid HA.
