Initial loading programme

Average horses and ponies:
Day 1-35 : Give 2 scoops daily

Transition period

Average horses and ponies
Day 36-60: Give 1 scoop daily

55 Synequin for my 17yo ex eventer
Verified Purchase

By on 8 June 2021

This product has really helped my horses joint mobility and also has reduced leg filling when stabled. It takes a couple of months to build up in the system but he has 1 sachet per day in the season and 1 every 2 days in the winter and it works for him.

55 Excellent service from Viovet. Synequin very good
Verified Purchase

By on 22 February 2021

The Synequin product is excellent. My horse has been on it for about 13 years as he was diagnosed with ringbone. I think it has helped enormously. I still ride him most days and he is now 20 yo.

55 Works for my horse but you need to be patient!
Verified Purchase

By on 7 October 2020

This was prescribed by my vet for my horse following diagnosis of DJD in coffin joints of both front feet 5 years ago. Vet warned me it can take sometime to work in my case 18 months (luckily enough the loading period covered by insurance). By then he improved to the point where he can now be gently hacked out twice per week. After the loading dose, the maintenance dose makes this product affordable as a 1kg tub lasts about 8 months. Eats happily in food

55 Effective Supplement for Arthritic Horses
Verified Purchase

By on 3 June 2020

This product changed my horses life - he had begun to have arthritic changes in his hocks about six years ago, when he was aged 19. My vet recommended Synequin and it has been so effective it has prevented the need for any further treatment for the last six years and he has continued to be in full work and low level competitions. He is 25 years old in two days and still going strong. I cannot recommend this product highly enough.

Any adverse impact on Lami risk pony?

Emma Carpenter

  • VioVet customer since 2021
  • From: Worcestershire, United Kingdom

Pony overweight and restricted exercise following soft tissue injury. Never had laminitis but is a circumstantial to use this?

  • VioVet Staff

You will need to avoid high sugar supplements in horses with a laminitic risk. The ingredient list VetPlus have provided for this product does not contain sugar and so this should be safe. Unfortunately VetPlus have a policy of not discussing any of their products with online pharmacies so I cannot confirm the ingredient list for you, if you would like confirmation of this then please contact them direct so they can provide it.

Hi, can you tell me the loading and maintenance dosage for a 700kg horse, thanks

  • VioVet Staff

For horses over 500kg the loading dose is 3 scoops a day for 35 days, followed by a transition period of 1.5 scoops from days 36-60 then reducing gradually to a maintenance dose of 1 scoop every other day. However you should monitor your horse- it may be that 1 scoop every day is required to maintain mobility and comfort depending on their condition.

What is the maximum dose I can feed my 26 yr old TB on a daily basis. He is on one and a half sachets per day but I feel that he was going a lot better when giving him the loading dose of 3 sachets a day. Thanks in advance for your advice. Regards.

  • VioVet Staff

It is safe to continue with the loading dose indefinitely. Usually the dose is reduced because it seems to work pretty much just as well after a while and is of course cheaper. It is safe to continue on the full dose if that is beneficial.

11 July 2015 at 7:08pm

All in one meal?

Jayde davies

Sorry another question the loading period suggests 2 scoops/sachets a day my ponies has one meal a day with turmeric and bute in a syringe can he have the 2 scoops or sachets in one meal or better he has 2 separate meals or syringed if he won't eat it

  • VioVet Staff

These products should be OK mixed together in one meal. If he is not keen on it that way, you might have to split them up a bit. See what works with him.

11 July 2015 at 7:01pm

Combined with other meds

Jayde Davies

Will the product be safe to use with turmeric and bute

  • VioVet Staff

It is safe to give with both turmeric and bute. In fact these products are quite often combined and it is thought that they can work synergistically together, improving overall results.

Will this benefit my pony with arthritis in his coffin joint ?

Jayde Davies

My vet had mentioned this product to me I was just wondering if it would be beneficial for my cob who has arthritis in his coffin joint ? He's been badly lame now for about 2-3 months and recently had a nerve block and has been put on bute to see how he gets on, would this help him at all ? And would he have to come off the bute to have this ?

  • VioVet Staff

This product is safe to give alongside other treatments and is often combined with "Bute". I cannot tell you if it will work for your horse as results seem to vary from one to another, but many horses do improve. Sometimes you need to give it for a few weeks before you see a full response, so do not give up after a few days if it does not work immediately. If it does work then ideally you give it for life, though you might not need to.

Missed transition dosage

Louise Brown

  • VioVet customer since 2013
  • From: West Yorkshire, United Kingdom

Hi - I started using Synequin in April. I completed the loading dose as stated but missed out the transition dosage and went straight onto the maintenance dosage for my 16 2 hh TB. Will it make any difference to the outcome or should I revert to the transition dosage?

  • VioVet Staff

This is unlikely to make any significant difference so I would tend to continue with the maintenance dose. However if your horse has shown particularly severe symptoms of stiffness/discomfort then it would be advised to increase to the transition dose to try and get the maximum benefit possible. Doing this is unlikely to affect the long term outcome at all, but it might give a slightly quicker response.

Loading Dose

Karen Greaves

  • VioVet customer since 2015
  • From: Orkney Islands, United Kingdom

My 19 yr old 17hh Clydesdale X has been on Superflex. I've ordered Synequin - would you still recommend a triple dose for 35 days to start with?

  • VioVet Staff

It should be fine to go straight onto the maintenance dose from the start. If you were to go onto a loading dose initially it would not cause any trouble, but I would not expect you to see any extra benefit from it.

14 January 2015 at 3:54pm

Synequin regular use

Robin nash

Once into maintenance mode, can you feed on 5g every day or does it have to be 10g every other day?

  • VioVet Staff

It is perfectly OK to give 5g daily, instead of 10g every other day.

How long it lasts


i am interested in the synequin for my two horses, both currently on glucosamine but think they need something stronger.
one of the is a lightly built 16.2hh 18 year old tb who is getting generally stiff as he gets older, still leads an active life but finds it more difficult to lift his back legs for the farrier etc
the other is a 17hh ish who has very clicky hocks and although seems fine and happy in himself to lead an active lifestyle he is slightly stiff in the hock too
do you think this would be the most effective product and how long would a 1kg tub last for them?
kind regards

  • VioVet Staff

Synequin has generally been regarded as the gold standard in glucosamine supplementation and is a very good choice, though different horses can seem to respond to different products. At a maintenance dose rate, a 1kg tub contains 100 days worth of medication for 1 horse. Ideally a triple dose is given for the first 35 days for a horse which has not had supplements before.
