Most people aren’t familiar with the benefits of SAM-e for dogs, but it is becoming increasingly popular amongst pet owners in the know. But what is SAM-e? What does it do? Which version of the supplement is right for your dog? And does it work?

SAM-e is a supplement that helps the liver to create more vital antioxidants which fight against liver damage. The liver cleanses and detoxifies the blood, so it’s important to ensure it is functioning properly.

Like humans, many dogs are also prone to liver problems and pet owners have reported real improvements when using SAM-e.

While liver support is the number one benefit of SAM-e for dogs, it is believed that SAM-e can also help in other ways – including protecting bones and joints, increasing cognitive functions and helping to control pain.

Does SAM-e Work?

This is the $64,000 question. Ask most pet owners who’ve used it and they will say yes, absolutely. There hasn’t been enough clinical research carried out yet to prove anything conclusively and the evidence of the benefits of SAM-e so far are mainly what pet owners report.

That said, SAM-e is prescribed by many vets and the feedback we’ve had from dog owners suggests it does work. Hopefully more clinical trials will be carried out soon to prove provide scientific proof of how effective SAM-e really is for dogs.

The key thing to know is that SAM-e is safe to give to your dog. There are no major side effects if given in accordance with the guidelines on the packaging. We know there have been a few reports of vomiting but this is rare and if it happens you would just stop giving the supplement.

There are several different versions of the supplement and we’ll be looking more closely at each. All these supplements can be found in some good high street pet stores or bought directly from Amazon.

A Complete Guide to SAM-e for Dogs

How does SAM-e work?

SAM-e is the abbreviated term for S-Adenosylmethionine (which is why we just call it SAM-e!). It is a chemical made naturally in the body from a food-derived amino acid called methionine. Even though SAM-e is made in the body, many dogs with poor liver function benefit from an extra booster of it in supplement form to help with the liver, brain and joints.

SAM-e is an intelligent substance. Once it reaches the system, it undergoes transformative processes which convert it into antioxidants. One of these powerful antioxidants is glutathione which helps to cleanse and protect the cells in the liver.

If the liver is not functioning as well as it should then it produces less SAM-e, which means less glutathione antioxidant is produced. Less of this antioxidant means even more of the liver cells get damaged, which means less SAM-e is produced… and so on in a vicious circle.

The idea of using a SAM-e supplement is to help the liver protect itself by allowing it to produce more of the glutathione antioxidant.

Getting these glutathione levels up can make a huge difference in liver function and health and may even help encourage cells to heal and repair themselves. As an additional benefit SAM-e also helps with promoting anti-inflammatory and pain-relieving antioxidants.

Is it right for my dog?

SAM-e has been recommended for various forms of liver disease in animals. These include:

SAM-e could also be useful in helping support the liver of pets that are receiving long term treatment for epilepsy and other diseases where the liver has to metabolize the medication.

There are other reported benefits of SAM-e for dogs.

Protects the bones and joints

Joint health is something many dogs have troubles with. SAM-e is a fantastic supplement to give to dogs with joint issues such as osteoarthritis. SAM-e helps to reduce inflammation and helps the keep the tissue surrounding the joints strong and healthy.

Supports cognitive function

SAM-e is often prescribed to dogs who have cognitive issues such as depression. A sharp, healthy brain will help your dog to ease into his or her later years. SAM-e is great for brain health and cognitive function because it helps to synthesize choline in the body, which is an important macronutrient for brain health.

Helps to control pain

SAM-e has analgesic properties, which means that it helps to relieve pain. Together with its anti-inflammatory and joint-supporting abilities, SAM-e is great at relieving osteoarthritic pain which can be debilitating for dogs.

Because SAM-e helps to prevent damage to cells we have found it has also been recommended for other conditions including:

  • Pancreatitis
  • Diabetes
  • Inflammatory bowel disease
  • Autoimmune disorders
  • Cushing’s disease
  • Some anemias
  • Some heart conditions

There hasn’t been any research into how beneficial SAM-e is for these conditions but hopefully there will be soon.

Is Denamarin the same as SAM-e?

Another popular liver-support supplement for dogs is called Denamarin. It’s a common confusion among consumers and pet owners; is Denamarin the same as SAM-e? Denamarin does contain SAM-e, but it is paired with another ingredient called Silybin. Silybin is an antioxidant, which also helps with liver support. You can find out more about Denamarin here.

How to give your dog SAM-e

Most SAM-e supplements come in the form of tablets, which must be taken on an empty stomach, an hour or so before food. The tablet needs time to break down in the stomach and the SAM-e to be ingested. We all know dogs don’t like taking tablets so one trick is to wrap the tablet in a small treat or piece of food. Please don’t break the tablet. It has a special coating which helps protect the SAM-e from stomach acid.

Fortunately for dog owners SAM-e also comes in powder form, which is easier to give. The powder supplements can be mixed into pet food for a (hopefully) traceless dose.

Storing SAM-e

You need to take a bit of care about how you store the SAM-e as it is very easily damaged by moisture or extreme temperatures. The best advice is to store it in a child proof container at room temperature – kitchens and bathrooms are not great places for storing SAM-e. If the tablets are in foil packs, then only take the tablet out of the foil when you are ready to use it.

SAM-e product supplement reviews

There are many SAM-e supplements designed for pets, each with different features, pros and cons. Some are in tablet form, some are chewable and some are even powdered. Some supplements have added active ingredients such as B vitamins and zinc, while others have SAM-e as their sole active ingredient.

MaxxiSAMe SAM-e Liver Supplement for Dogs & Cats

MAXXI SAM-e Liver Supplement for Cats and Dogs is a powered supplement which can be added to your pet’s food. This supplement contains added nutrients and vitamins to provide pets with ultimate system support.

Features

This SAM-e supplement comes in powder form, which is a great feature for dogs who just cannot tolerate swallowing capsules or pills. The powder is designed to be sprinkled onto, or mixed in with your dog’s food. Most dogs don’t seem to have a problem with this, but some dogs know when something unusual has been added to their food and refuse to eat it.

As well as SAM-e, this powder supplement also contains artichoke, Choline and Inositol.  These ingredients have been chosen because they support the liver and brain.

For SAM-e to be effectively absorbed into the system, it requires the help of B vitamins. B vitamins have been added to the MAXXI SAM-e supplement to assist with fast and effective absorption.

Pros
  • Does not need to be taken on an empty stomach (add powder to food)
  • Contains B vitamins for SAM-e absorption
  • Fast absorption
  • Supports healthy brain function
  • Supports healthy liver function
Cons
  • Some consumers have commented that their dogs refuse to eat their food when this product is added to it. While this is not a fault of the product or company itself, it does show that not all dogs will tolerate a powder being sprinkled on their food and may do better with capsules

Features

Conclusion

As ever, if you’re unsure or want detailed advice about your pet’s specific needs talk to your vet. It may also a good idea to get a set of blood work done to test your pup’s liver levels and function, as this will give you an idea of what he requires in terms of added ingredients.

The liver is such an important organ (for all of us!), so it’s crucial to give it all the support we can. If SAM-e supplements are as effective as people claim then they are one of the best things you can give your dog to keep their liver healthy. You can feel great in the knowledge that you are giving your dog a supplement which will not only support his liver, but also his brain, joints and overall health.
