Synoquin EFA, one of the leading joint care supplements aids stiff joints and supports 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.

For horses there is the palatable powder Synequin Equine.

Synoquin for cats


  • VioVet customer since 2018
  • From: , Hungary

Looking for a glucosamine product for my 11 yr old cat just diagnosed with cauda equina. Vet suggested Synoquin but fuzzy on the details re: dosing, etc. and which is appropriate for cats, also whether it comes in tablet or capsule form. Would prefer a capsule. Can you advise? Thanks!

  • Veterinary Advisor

You will need the Synoquin Cat EFA Capsules (at the top of the drop down menu). They come in capsules which can be given whole or opened and mixed with food. Feeding guidelines:

Initial programme (6 weeks):
2 capsules daily in the morning and in the evening

Maintenance programme (long term):
All cats respond differently to supplementation. However, in general, after the initial loading programme the daily intake can usually be reduced to 1 capsule per day.

Can I crush the tablets?



My dog is very clever and even stuffing a tablet in a juicy sausage she will refuse it and somehow eat the sausage and spit the tablet out. Can you crush the tablets or open the capsule and sprinkle in food?

  • Veterinary Advisor

Yes you can do either of these things. It would be easiest to use the capsules so all you have to do is sprinkle them on the food and so avoids wastage as with crushing tablets.

Could i feed 'puppy growth tablet' for my dog?

Jenny Lee

I send this email because i have some questions about feeding guideline.

1. My puppy is 5months old, so what is better for my puppy? Small breed tablets or puppy growth?

2. If 'puppy growth' is better for my dog now, When should i change 'puppy growth' to 'small breed tablets'? Maybe 1 year old?

3. If i change the medicine, should i feed 2 tablets for everyday during 6-8weeks?

I'm wating your reply.
Thank you for your kindness.

  • Veterinary Advisor

The puppy growth tablets would be ideal until your puppy is 12-18 months old when you can switch to the small breed tablets. The recommended feeding guideline for the puppy growth tablets is one tablet twice per day.

I ordered this product yesterday and would like to know about the Feeding guidelines.
People said they need to feed this supplement to their dog twice a day. (They said one for morning and one for evening.)

My dog weights about 12-13kg, and I purchased Medium Breed Tablets Pack of 120. How many and how often should I feed him per a day?

  • Veterinary Advisor

Medium Breed Tablets (Dogs between 10 - 25kg)

  • Initial Loading rate for six weeks: 3 tablets daily (2 morning, 1 evening)
  • Maintenance rate for long term use: one tablet daily

All dogs respond differently to supplementation. If the reduction causes your dog`s condition to regress, intake can safely be increased until an optimum level is reached.

Puppy Growth or Small Breed?

amy pixie

My pixie is 11 months old with weight 3.2kg which one should i order for puppy growth or small breed?

  • Brand Manager

Generally, very small breeds of dogs have finished growing, and are regarded as adults from about 10 months of age. I recommend putting your dog onto the Small Breed tablets/capsules.

My girl (11.5kg) is taking another brand joint supplement for a while and would like to change to Synoquin instead. In this case, should I just give the dosage as "Maintenance" or need to start from "Initial"? Thank you.

  • Veterinary Advisor

It really depends on which joint supplement you previously used. If the ingredients are very similar (which most joint supplements tend to be) then starting on the maintenance dose of one tablet daily should be sufficient.

How much protein does synoquin contain?


My old girl is currently on a prescription kidney diet. I've been advised that she needs reduced protein. How much protein is in synoquin?

  • Non-Executive Director

On a percentage basis, Synoquin is high in protein (38% of the 1.1g capsules for example, mostly down to the gelatin capsule itself). However this is not the point because you are not feeding her whole meals consisting of mainly Synoquin. The total amount of protein in a capsule is less than half of a gram, which is completely negligible as a contribution to the protein level of the overall diet. As long as you are using Synoquin at the sort of dose levels advised, you do not need to worry about its protein content.

My cat was recently diagnosed with ckd. We are managing this through diet and sub cuts. She also suffers from arthritis and has been on synoquin long term. We have just managed to get her eating again. Can you let me know if it safe to start the synoquin again in light of the ckd?

  • Non-Executive Director

Synoquin should be perfectly OK to give her as long as she is eating and drinking reasonably well. If either of these are not adequate, the they are more important and you have to concentrate on them. Otherwise it is a good plan to help her joints as much as you can.

Brian Holland

Can Buddy, a staffordshire bull terrier 13 yrs of age, take SYNOQUIN whist taking prescibed ant-inflammatory tablets.

  • Brand Manager

The ingredients in Synoquin are unlikely to react with those of prescribed medication but it would be worth checking with your vet for Buddy's specific medication. A lot of supplements can be used very safely alongside anti-inflammatory medications.

Synoquin EFA


Hi, wondering if my dog can consume Synoquin EFA as she having liver issues & one of the ingredients –krill really concern me. Thanks a lot.

  • Non-Executive Director

Synoquin EFA is probably the leading brand for canine joint supplements. The krill component is an oily extract from the krill which is high in omega-3 fatty acids, as well as antioxidants. These things are thought often to be beneficial in liver disease, though it depends to a certain extent on the precise nature of the disease process occurring in the liver. My initial reaction would be to say that Synoquin EFA is probably a good choice for your dog. If you are still concerned then a brand like Cosequin is very similar in other ways, but does not have the krill extract.
