Samylin is a food supplement used where there are concerns regarding liver function. Samylin contains SAMe which is a precursor of glutathione. This is known to be required by the liver and elevated levels are able to increase the effective functioning of the liver. Other ingredients include the antioxidant and thiol donor Silybin (found in Milk Thistle), Vitamin E and Vitamin C. Samylin is used at a rate of one sachet per 5kg of bodyweight per day, mixed with food. The tablets should be given whole, it is not recommended that they are crushed before being fed.

55 Effective treatment of liver problem
Verified Purchase

By on 22 March 2019

Our dog (miniature schnauzer) was diagnosed with liver malfunction at the age of 12 (after repeated incidents of sickness without eating anything bad) and local vets recommended Samylin supplement (which I bought from Viovet online). Indeed, it had a fantastic effect - our dog's sickness incidents stopped and never repeated, as we kept giving him a half of recommended dose daily for the rest of his life. He lived almost 16 years.

55 Wonderful product for a poorly pooch
Verified Purchase

By on 31 July 2018

This was recommended by my vet as my beloved Whippet,Ptolemy suffers from almost permanent Pancreatitis of varying degrees of seriousness. That and an Auto Immune disease take a heavy toll on his fragile body. This really helps to boost his compromised liver ,and our Vet is pleased with his blood-work at the moment. Well worth considering to help your best furry friend. The only small downside s that there is quite a lot of very fine powder in the sachets which he's not too keen on licking up with his food, or hiding in boiled chicken he also discovers this "paste"by then and licks around it. I've just ordered the capsules for easier administration!

Q & A

Below are some recent questions we've received regarding Samylin Liver Supplement for Dogs, including answers from our team.

Side effects on very senior dog taking Samylin?

April Young

Just been given Samylin tablets for my 16yr old terrier to boost his liver function after ultrasound at vets. No leaflet with the box of tablets. Want to know what to look out for in my dog in response to these supplements to be taken for 6 wks. Thank you

  • VioVet Staff

Samylin is a supplement so there are no listed side effects for the product, like you would find with a licensed medication. However similar to any food your dog could be allergic/intolerant to one of the ingredients. This can show as skin or gastrointestinal issues (vomiting/diarrhoea). If any of these occur then you should see your vet to discuss further.

Prescription or over counter?


I have received Samylin Medium from the vets today. I am unsure if it was on prescription - does it have to be?

  • VioVet Staff

Samylin is a supplement and so can be bought over the counter without prescription.

Diabetic vs Samilyn

Wena Cintiawati

is it okey to give samilyn to my senior diabetic mini dachshund?

  • VioVet Staff

There are no specific ingredients in this supplement that are a cause for concern with diabetics. However any change in diet can affect your dog's insulin requirements so you should run the use of this supplement past your vet to be safe.

Dosage for dogs

Monica Gunawan

Hi I have 9 kilo dog, it says to give 2 small instead of 1 medium. For the sake of purchasing (giving two means double the price) is it safe to give one medium tablet instead maybe with longer interval days ? Thank you

  • VioVet Staff

I recommend contacting the manufacturer direct (VetPlus) regarding your query as unfortunately they won't discuss customer queries with us. They should be able to advise on this.

Any good for gallbladder problems?

Kerry Dean

  • VioVet customer since 2016
  • From: West Yorkshire, United Kingdom

Hi, my beagle has been diagnosed with sludge in his gallbladder and is taking various meds but the vets has said this may also help. With it mainly making reference to helping with liver complaints, do you know if it can help the gallbladder? Thanks

  • VioVet Staff

The gallbladder is contained just within the liver lobes, with the bile duct closely involved with the liver itself. For the gall to be produced normally the liver must be working effectively so it is highly likely that this close relationship is why your vet has recommended the product. If the gall bladder is affected then it could have a knock on effect on the liver. I advise asking your vet this question too so they can provide a more specific answer for you.

Samylin tablets

M gillingham

Does samylin tablets require a vets prescription? So I can purchase.

  • VioVet Staff

Samylin tablets are over the counter supplement tablets, they do not require a written prescription and they are not classed as medications.

Crushing tablets

Helen Gilbert

Having difficulty getting my dog to swallow the medium tablet now. Can I crush it and add to food? Thanks

  • VioVet Staff

Yes it is fine to crush the tablet and give it in food. Samylin is also available in powder form which might be easier the next time you buy it.

Use in cats?

Patricia Hickey

  • VioVet customer since 2016
  • From: Greater Manchester, United Kingdom

I've just ordered Samylin Liver Supplement for dogs is it okay to give to cats because my have it to me last time

  • VioVet Staff

Samylin is marketed just for dogs by the manufacturer and so we have to follow this lead and advise that it is intended just for dogs. However all the active ingredients are sometimes used in cats and the main ingredient is indeed regarded as helpful and very safe for cats with liver trouble. If you choose to use it in a cat this is up to you, but I think it would be safe.

Feed with other supplements

Chen Chi (josefa) Hsu

  • VioVet customer since 2015
  • From: , Hong Kong

hi, doc, i bot samylin for years and always mixed with food and other supplements like fish oil, probiotic and vitamin c. my dog has been ok and didnt have any stomach upset. i am wondering if this way of feeding is ok and any restriction when feeding samylin. thank you!!

  • VioVet Staff

Samylin is usually given with food and it can certainly be given with the other supplements you mention. I do not see any problem with you doing this. There are some supplements which can potentially cause trouble in themselves, particularly those containing vitamins A or D. Overdosing those can cause trouble. As long as you avoid that and you generally only give supplements in the quantities recommended by the manufacturer, it should be safe. You might not need to be giving so many supplements; most dogs do not need them if the general diet is good quality. However this is up to you. Obviously check with your own vet if you are unsure about anything, or about your dogs medical conditions generally.
