SAMe liver and cognitive support for medium dogs – Nutramax Denosyl provides 225 mg of S-Adenosylmethionine (SAMe) per tablet, supporting the liver’s production of glutathione, one of its key antioxidants, and supporting cognitive function in older dogs. Made in the USA, available in the UK at Boss Pets.

How to give it – SAMe products are generally given on an empty stomach, around an hour before food, and the enteric-coated tablet should be swallowed whole rather than crushed or split. Follow the label or your vet’s instructions.

Used under veterinary direction – Liver problems are diagnosed by blood tests and monitored over time. Abnormal liver results, jaundice, vomiting or appetite loss should be investigated by your vet rather than managed with a supplement.

Key Features

225 mg of SAMe per tablet – S-Adenosylmethionine, the active ingredient, for dogs of 13–34 lb (6–15 kg).

Supports the liver's antioxidant defences – SAMe is used by the body to make glutathione, one of the liver's key antioxidants.

Supports cognitive function in older pets – SAMe has also been studied for age-related changes in alertness and awareness.

Enteric-coated tablet – The coating protects the SAMe from stomach acid, so tablets are swallowed whole rather than crushed or split.

Given on an empty stomach – Generally around an hour before food, which is how the tablets are designed to be absorbed.

From Nutramax Laboratories – A long-established name in companion animal supplements. Sized for medium dogs.

Benefits

Ideal for Dogs with Liver Conditions – Supports the liver during illness, medication use, or aging.

Encourages Mental Alertness & Focus – Beneficial for dogs with signs of cognitive decline.

Easy to Administer Daily – Small, coated tablets are designed for effectiveness and ease.

Reliable USA-Made Formula – Now available in the UK at Boss Pets.

How to Use

Dog Weight & Daily Dosage:
13 – 34 lbs – 1 tablet daily

Give on an empty stomach, ideally 1 hour before or 2 hours after food.
Do not crush or split tablets, as the enteric coating is essential for proper absorption.

How It Works

S-Adenosylmethionine (SAMe 225 mg) – Boosts liver-protective antioxidants and supports neurotransmitter activity for mental clarity and energy.

Enteric Coating – Protects the tablet until it reaches the small intestine for maximum absorption and effectiveness.

Why Choose

A single-ingredient SAMe product – Denosyl contains SAMe alone; Denamarin adds silybin. Your vet can advise which fits your pet.

Strength matched to size – 225 mg tablets for dogs of 13–34 lb (6–15 kg), rather than splitting a larger tablet.

Studied in veterinary use – SAMe has been researched for liver antioxidant support and for cognitive function in older animals.

Used alongside veterinary care – Liver problems are diagnosed by blood tests and monitored over time, not judged by how a pet seems.

A specialist UK stockist – Boss Pets carries an extensive Nutramax range, with fast UK delivery.

FAQs

Can Denosyl help with early liver disease? – Yes, it helps manage liver conditions by increasing glutathione levels and supporting detox.

Will it improve my dog’s focus or memory? – Yes, SAMe also supports brain function and is helpful for senior pets with cognitive decline.

Can it be combined with other liver supplements? – Yes, but consult your vet to confirm safe combinations.

How quickly will I see results? – Many dogs show improvements in 2–4 weeks of daily use.

Where can I buy Denosyl in the UK? – From Boss Pets, your trusted UK source for USA veterinary supplements.

FAQs

What is the difference between Denosyl and Denamarin?

Denosyl contains SAMe. Denamarin contains SAMe plus silybin, a concentrated and more absorbable component of milk thistle.

How much SAMe is in each tablet?

225 mg, which is the medium dog strength. Small dog and cat tablets contain 90 mg, large dog tablets 425 mg — use the one matching your dog’s weight banding on the pack.

How should I give it?

On an empty stomach, around an hour before food, swallowed whole. The tablets are enteric-coated, so crushing or splitting them undermines how they work.

What if my dog will not take it on an empty stomach?

Ask your vet. Giving it with food reduces absorption, so it is worth getting their advice rather than changing the routine yourself.

Can I give it with other medication?

Tell your vet everything your dog is taking, particularly if they are on prescribed liver medication.

When should I see my vet?

Jaundice, vomiting, appetite loss, lethargy or abnormal liver blood results all need veterinary investigation.
