Flexadin Advanced with UC•II® Extra Strength is once-a-day joint support for dogs and cats that’s so powerful it is only available from a veterinarian. Flexadin Advanced Extra Strength is equivalent to the amount of UC•II® in two Flexadin Advanced chews. A single chew increases the likelihood of client compliance with daily joint support.

Flexadin Advanced with UC•II® is an innovative supplement that supports healthy joints and flexibility in dogs and cats. UC•II® has been clinically proven to be more effective than glucosamine and chondroitin.*

The breakthrough formula supports healthy joints in dogs and cats of all ages — and sizes. Just one chew, once daily can help any size pet. That makes Flexadin Advanced perfect for homes with multiple dogs and cats.

Flexadin Advanced Extra Strength:

  • Is only available from a veterinarian
  • Helps enhance a pet’s normal repair of cartilage and joints
  • Helps maintain joint function
  • Helps maintain joint mobility and flexibility
  • Works differently than other supplements containing hydrolyzed collagen peptides, glucosamine, chondroitin, or CBD

The unique formula also can ease joint stiffness and promote normal cartilage health.

Joint supplements only work if a pet accepts them — and dogs and cats love the taste of Flexadin Advanced with UC•II®!
