    Glyco Flex II by Bev10/02/2013

    My cats really enjoy this product. Unlike other joint meds we have tried, this is one that they readily consume. It's easy to prepare (1/2 tab for each cat) because the pill is scored for easy breakage. The price is also atttractive.

    This product definitely helped my cat. He is 17 years old and is doing very well on this supplement. He can get up and down steps with less difficulty.

    You must have this! by kitty mama11/13/2009

    Just 2 weeks in and my 10 year old boy is running around like he is a kitten again. Jumping, playing and chasing the other cats. You really must try this, it is an excellent joint product!

    Very very helpful by Katie C. from Langley, B.C. Canada03/19/2013

    My cat had arthritis in her hip joints starting at age 6. When we heard of this product from a vet she was age 10 and we started to give it to her. We noticed she was more active after 10 days, and the improvement continued to increase for 6 weeks until she reached a good level of stability. We have now been using the product for 2 years and she is still much improved over 2 years ago. She can jump higher and has more energy. She moves much more than before we gave them to her. It's a great product I would definately recommend.

    This works for small dogs too! by Lucyloo04/08/2008

    This product makes my 12 year old Papillon act like a puppy again. She is so happy and so much more comfortable when she consistently takes this supplement. Highly recommend.

    She likes It. by charger from St Louis, Mo03/06/2014

    She stopped limping and I am assuming it is because of ( or partly due to) this product. She likes it. It is pretty big even when you use a half pill, so I cut the half in half. She always eats it when I put it on top of her canned food. ( this surprised me a bit). I wish it came in a bigger ( more pills) bottle.

    GLYCO-FLEX II by DJ10/23/2012

    I have been giving glyco-flex II to my 13 year old kitty for 8+ months now and it has really helped the stiffness in her hip area. Plus, she like it! I just break it up (it's kind of big) into 4 pieces and she eats them right up.

    works great by Ilene from california07/31/2013

    My 12-year old male cat was starting to have difficulty with his back legs on cold winter days. He was stiff and some days could hardly move. Shortly after starting on the Glyco-Flex he was back to his old self - running, jumping and playing like he always has. He has been taking 1 pill per day for years now and is still going strong. I recommend this product to anyone with an older cat who is having arthritis-like symptoms.

    Good for one cat, bad for other. by Cresentia from Pittsburgh, PA06/23/2013

    I feel these would be good if you have a cat with joint issues. I gave to my two older cats to prevent joint issues but they made one of them regurgitate a lot more frequently while on them. The other cat tolerates them fine (but she rarely regurgitates her food). They both like the glyco flex I better as far as willingness to eat them.

    excellent product by cecil from durham nc10/23/2012

    My oldest cat had trouble moving and jumping, but after giving her the Glyco Flex she is a lot more mobile. She doesnt care to eat the pill whole, but the taste is fine-I just crush it and add it to her wet food..
