Synoquin ® EFA Synoquin EFA Large Breed for Stiff Joints in Dogs

Synoquin ® EFA

Synoquin EFA, our leading joint care supplement aids stiff joints and promotes mobility.  Synoquin EFA contains Dexahan, a unique source of Omega 3 Essential Fatty Acids (EFAs).  Omega 3 EFAs are an excellent supplement to add to your pet’s diet as they have lots of health benefits and are often used to aid in the management of joints.  Dexahan is a concentrated source of krill, a tiny crustacean with an especially big nutritional benefit!  The EFAs in krill oil are more easily digested and utilised by the body than those from other sources. They come from an environmentally friendly source, are packed with antioxidants and don’t cause your pet to get fishy breath.

What Else Can I Do?

There are a number of measures you can take that can support your dog’s quality of life and help maintain healthy joints

  1. Keep your dog fit and at the correct weight by feeding an appropriate diet. Excess weight can put extra strain on a joint, increasing the risk of damage. Speak to your vet for advice on feeding or weight loss diets
  2. Take your dog for three or four short walks a day rather than one long walk
  3. Walk your dog on a flat surface rather than steep inclines
  4. Provide a soft, comfortable and draught free bed
  5. Avoid slippery surfaces. Walking on polished wooden, tiled or linoleum floors can be difficult and increases the risk of injury
  6. Minimise the need to use stairs wherever possible

Why Should I See My Vet?

At VetPlus we believe vets are best placed to advise the best course of action for your pet. Joints provide the body with natural flexibility and shock-absorbing ability to allow your dog to cope with daily activity. The joints are extremely complex and your vet will be able to perform checks to ensure they’re healthy.

Feeding Guidelines

Synoquin EFA is available in different forms and sizes to suit the size of your dog.

Available in Three Sizes

Synoquin EFA comes in a tasty chewable tablet or capsule and in three different sizes to suit the needs of every breed of dog.

It may require an initial loading programme, after which the daily intake can be reduced to maintenance level. This will depend on your dog’s response and you should consult your vet for guidance specific to your dog.

Weight Initial Loading Maintenance
Under 10kg 2x small breed 1x small breed
10-25kg 3x medium breed 1x medium breed
26-40kg 3x large breed 1x large breed
Over 40kg 4x large breed 2x large breed


Synoquin EFA contains a unique combination of:

  • Chondroitin sulphate – a key nutrient for healthy cartilage and joint fluid
  • Glucosamine hydrochloride – one of the basic building blocks for cartilage and joint fluid
  • Dexahan – a highly purified form of krill oil that acts as a rich source of omega 3 fatty acids as well as providing astaxanthin, a potent antioxidant
  • Zinc – important in the metabolism of cartilage and bone
  • Vitamin C – a water soluble antioxidant vitamin

The Krill used in Synoquin EFA is fished sustainably via a Marine Stewardship Council (MSC) accredited supplier.
