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!

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

  • 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.

Because dog is higher levels of liver saemilli
to be eating falls was bad liver numbers, Could you recommend if you have anything
better. We ask, please! "please"

  • VioVet Staff

Samylin is regarded as one of the best liver supplements and it is likely to be as good as any supplement of this type. Some liver conditions can respond to antibiotics or steroids or other prescription medication, so your own vet can advise you on these. Ideally you need to make a precise diagnosis and then treat that condition as well as you can. Raised liver enzyme levels usually indicates liver damage, but tells you nothing about why that damage has occurred. This should be investigated. Sometimes it can be caused by a bad reaction to other medication which has been given, so if your dog is on any other medication which could be causing the damage, you should consider stopping that immediately.

Samylin tablets

MRS S POUND (dupon2141)

  • VioVet customer since 2013
  • From: SURREY, United Kingdom

Are these given on an empty tummy as there are no details in the box.. I assume the powder is sprinkled on the food but are the tablets also to be taken with food
Thank you

  • VioVet Staff

This product is normally taken with food. The tablets can be given whole or crushed, but some food is normally given at the same time or afterwards. The powder is much better given with some food.

If the dog stops taking this can it damage it thanks

  • VioVet Staff

Hi Maryann,

If the vet has recommended you stop giving this to your dog then that's fine. Otherwise the dog would just not be getting any liver support.

Hope this helps,

Ym Heo

What is the difference between small and medium breed?Is it only capacity of difference or there are other differences or ingredients?

  • VioVet Staff

The difference is purely in the amount of ingredients per sachet, they are the same otherwise.

Right dosage for a heavy cat.

Allan Feliciano

My cat weighs seven kilos and his ALT has been so high. We have been giving him two packs of samylin for months. Should we be giving him ONE or TWO?

  • VioVet Staff

It is safe to give 2 sachets for such a large cat, but I would be tempted to give just one sachet daily from now on. I would also suggest that if your cat is overweight (it certainly sounds like it must be) then very gradual weight loss would be very helpful too. Fat builds up in the liver and is not a good thing.
