Where is this product made? Where are the ingredients sourced from?

This product is made in Canada. The majority of the ingredients are sourced in Canada as well as the USA.

How long does this take to “kick in”? I have a 20-lb cat and no improvement in almost a month... should I keep giving them to her because it takes a while? The vet told me to get these....

Answer by Chewy • Oct 17, 2020
The amount of time it takes for these chews to have an effect on your pet will vary based on their current condition, weight, and eating habits among other factors. We recommend reaching out to your veterinarian with any questions you have regarding the efficacy of this supplement.

Can dogs with renal insufficiency take these? What is phosphorus content?

Answer by Chewy • May 20, 2021
There are no contraindications for Flexadin Advanced Chews with UCII for Dogs & Cats. The manufacture does not measure for phosphorus content. These chews are only 3 grams each and the directions are to give 1 chew per day for any size cat or dog. It would be a very small amount of phosphorus in each chew.

What is the calorie content of each chew?

Answer by Chewy • Nov 14, 2019
These chews contain approximately 15 calories per chew.

Not a tasty chew

My vet recommends this for my senior's joint support, but the only way he'll eat it is if I put it in the bottom of the pan with a little kibble, then smother it with his home-cooked meal. He'll eat the kibble & inadvertently eat this, too, only because he gets a pup cup for finishing. Why can't good-tasting chews be made? The price point is so high, too. I may or may not continue this in his supplement routine, pending noticeable improvement.

It's only been 3 weeks but this product had no effect on helping with her lameness after vigorous physical activity. I don't want to down rate it though as I have tried more than half dozen hip/joint chews and none have helped.

Our 7 year old dog has arthritis pretty bad, nothing the vet has given us or recommended us to try has worked. I found Flexadin and we’re about through our first month, we’re both loving it! She’s able to walk noticeably better, even running and playing more. Seriously, I’m not one who takes time to write reviews on anything. This stuff works!

You have to give this supplement a good 2 months to fully kick in, but after the two months I really noticed a difference in my senior dog that has hip dysplasia. My vet recommended this supplement because it is actually backed by science, and my old lady is back to playing and running since being on it.

We are using this product with our second elderly dog now and it still works great! It really gives our dog relief to move freely almost like his younger self. Without the supplement he's very unsteady and we are so glad to have discovered this product to help him. I don't think you will be disappointed with your results with this. Highly recommend!

Philly can't take glucosamine products due to digestive distress. Philly was having trouble getting up our steep step from the back yard into the house. From the first day we have him one chew, he was better able to get up the step. As a senior dog, some days are better than others, but he has maintained function over the past 2 months. I highly recommend these chews!

Vet suggested. I'm not a believer on word so I rabbit -holed into learning about collegen for dogs. Different from human so anyone thinking they can just buy the human brand will be wasting money. I give both dogs green lipped mussel as routine. This Flexadin gave the extra boost needed and was quickly noticed.

My 14 year old dog has osteoarthritic changes in her foot/toe bones as see in x-rays. She has been constantly licking it and occasionally stumbling when out on walks. After 6 weeks on this product the licking is mostly gone and she is trotting again! I am very thankful!

This item from Chewy was $50 less for the same quality than what I had paid elsewhere and the convenience of having it delivered,so quickly was amazing.
