Description
Flexadin Advanced with UC•II Extra Strength Chews for Dogs and Cats
  • Flexadin Advanced with UC•II® Extra Strength is an innovative supplement that supports healthy joints and flexibility in dogs and cats.
  • One Chew Per Day: Adult cats and dogs of any weight only need to take one chew per day, making it easier on owners to administer.
  • Contains UC-II®: Undenatured type II Collagen (UC-II®) works more effectively than other joint supplements that contain chondroitin and glucosamine.1
  • Highly Palatable: 94% of dogs and 73% of cats enjoy the taste of Flexadin Advanced with UC-II.2
  • Flexadin Advanced with UC•II® Extra Strength contains 80 mg of UC-II® for more advanced joint support and is available in 30-count and 60-count bags.

Flexadin Advanced with UC•II® Extra Strength is once-a-day joint support for dogs and cats that’s so powerful it must be used under the supervision of a veterinarian.
Flexadin Advanced with UC•II® Extra Strength is equivalent to the amount of UC•II® in two chews of Flexadin Advanced with UC•II®. Based on a study, 80 mg of UC•II® can help pets more quickly.2 Plus, a single chew makes it easy to deliver extra strength joint support.
Flexadin Advanced with UC•II® Extra Strength is the right choice for dogs requiring advanced joint support, including high-impact competitors and high-risk breeds.
