Overview
Flexadin Advanced is a hip and joint chew built around undenatured type II collagen rather than the more common glucosamine and chondroitin combination, dosed as one chew a day for 60 days per bag.
Each chew supplies 40mg of collagen yielding 10mg of active undenatured type II collagen, alongside omega-3 fatty acids from flaxseed and fish oil and vitamin E. This undenatured collagen approach works differently than glucosamine, targeting the response around joint cartilage rather than supplying raw cartilage-building blocks.
- 60 chews, one a day dosing
- Undenatured type II collagen formula
- Omega-3 fatty acids and vitamin E included
- Suitable for both dogs and cats
Who it's for
Dogs and cats with joint stiffness where an owner wants a once-daily chew rather than a powder or liquid supplement. Not formulated as a treatment for acute injury, only ongoing joint support.
Strengths and trade-offs
Drawn from this product's published specifications.
- Once-a-day dosing, no measuring by weight
- Works for both dogs and cats
- Includes omega-3s alongside the collagen
- Different active ingredient than glucosamine formulas, harder to compare directly
- 60-count bag lasts about two months at one a day
Performance notes
The listing describes the formula's collagen mechanism as clinically studied, and it's dosed at a single chew daily rather than a weight-based multi-chew dose. Sixty chews cover roughly two months at that rate.
