By Dr. Lena Ortiz · Canine wellness writer · Published 2026-05-29 · Updated 2026-06-18
Flexadin Advanced takes a different route from glucosamine, using undenatured type II collagen (UC-II) in a single daily chew, and while its 4.7 star rating looks promising, it has not yet gathered visible written reviews on this listing.
Owners who want a once a day joint chew built on UC-II collagen and omega-3s rather than the usual glucosamine and chondroitin blend, for either dogs or cats.

You want a large body of written owner reviews before buying, or you are looking for a budget option, since this runs pricier than most at nearly $60 for 60 chews.

Overview
Vetoquinol Flexadin Advanced is a once a day soft chew that leans on undenatured type II collagen, known as UC-II, instead of the standard glucosamine and chondroitin approach. Each chew supplies 40mg of type II collagen from chicken cartilage, yielding 10mg of active undenatured collagen, plus 100mg of omega-3 fatty acids from flaxseed and fish oil, vitamin E, and 11mg of EPA.
The one chew a day dosing keeps it simple, and the formula is labeled for both dogs and cats, so multi-pet households can use a single product. The 60 count bottle works out to about a two month supply for one pet.
At roughly $60 for 60 chews, this is one of the pricier joint supplements in the category, and it is positioned as a clinically studied, vet-oriented formula. Note that this listing shows a 4.7 star rating but has not yet accumulated visible written reviews, so early feedback is worth reading closely.

Performance notes
Each chew is formulated around 40mg of type II collagen from chicken cartilage, delivering 10mg of active undenatured collagen (UC-II), paired with 100mg of omega-3 fatty acids from flaxseed and fish oil, 42mg/21 IU of vitamin E, and 11mg of EPA. UC-II works differently from glucosamine and chondroitin and is formulated to support joint comfort and mobility. As always, it supports rather than treats any joint condition, so check with your vet for a diagnosed problem.
What buyers say
This listing shows a 4.7 star rating but has not yet accumulated any visible written reviews, so there is little owner feedback to lean on. The roughly 10,000 units sold in the past month signal strong demand, but with no written reviews yet, it is worth reading early feedback carefully before committing.
What makes Flexadin Advanced different from a glucosamine chew?
Instead of glucosamine and chondroitin, it uses undenatured type II collagen, or UC-II, as its main active, delivered as 10mg of active collagen per chew. It also adds omega-3s and vitamin E. It is formulated to support joint comfort, not to treat arthritis, so talk to your vet about a diagnosed condition.
Can I give this to my cat too?
Yes, the label lists it for both dogs and cats at one chew a day. Because pets vary in size and needs, confirm the right serving with your veterinarian, especially for a smaller cat.
