Denosyl contains SAMe (S-Adenosylmethionine) to help support liver and brain health.

How it Works Tablets


How does Denosyl® work?

Denosyl has been shown to markedly increase liver levels of glutathione,1,2 an important compound for liver health formed when SAMe (S-Adenosylmethionine) is metabolized. Denosyl has also been shown to help protect liver cells from cell death3,4 and may help cell repair and regeneration.5

While best known for supporting the liver in dogs and cats, research has shown that the SAMe in Denosyl may help support cognitive function in dogs.6 Denosyl provides SAMe in a stabilized form to help with brain health and act as a neuroprotector.7-9



Administration of Denosyl Tablets

Because the tablet must be kept intact to prevent destruction by moisture, administration range is based on the nearest whole-tablet. The chart below is provided as a guide for administration. Daily administration may also be calculated based on 20 mg/kg of body weight and rounded to the closest tablet size or combination of sizes.

For optimal absorption, tablets should be given on an empty stomach, at least one hour before feeding, as the presence of food decreases the absorption of S-Adenosylmethionine. Studies have shown that, in many cases, tablets or capsules given as a “dry swallow” do not pass into the stomach in cats but may become lodged in the esophagus. It is recommended for pet owners to administer 3-6 cc of water immediately following any tablet administration to speed passage of the tablet into the stomach.10,11 Denosyl 90 mg tablets are ideal for cats because of their small size. If the pet is to receive more than one tablet daily, the total number of tablets may be divided between morning and evening for ease of administration. For example, a daily administration of three tablets could be divided into two tablets in the morning and one tablet in the evening.

Frequently Asked Questions

What formulations of Denosyl are available?

Denosyl is available enteric-coated tablets for cats and dogs.

How much Denosyl should I give my pet?

Your veterinarian will advise you as to the amount to initially administer. Depending on your pet’s response and status, your veterinarian may eventually adjust this amount to meet your pet’s individual needs. Remember, Denosyl enteric-coated tablets should not be broken. When increasing or decreasing their administration, adjustments should be done in full tablet increments. Some pets are given Denosyl only for a short period of time, although Denosyl may be used longer in other animals.

What should I look for when I give Denosyl?

While response varies, owners may note a change in their pet’s appetite, activity, and attitude.

How will my veterinarian monitor my pet's response while on Denosyl?

Your veterinarian will likely recommend follow-up examinations, blood work, and/or other laboratory work to check on how well your pet is doing with Denosyl and how it may be helping to support your pet’s liver function.

Are there any side effects?

Denosyl has been shown to be well-tolerated by both dogs and cats with a wide margin of safety.

Can Denosyl be used with other products?

Yes, your veterinarian may recommend combining Denosyl with other products and/or dietary modifications. There are no known adverse interactions of Denosyl with drugs or other supplements. Denosyl may even protect against negative effects on the liver caused by some medications.

Are other brands the equivalent to Denosyl?

While other S-Adenosylmethionine (SAMe) products are available, there can be a significant variance in product quality and activity levels of SAMe. Denosyl is produced using high-quality, researched ingredients and under strict manufacturing standards.

Since S-Adenosylmethionine is made from methionine, should I give my pet methionine?

Administration of methionine is not recommended. Providing high levels of methionine to pets with liver compromise may not increase the production of natural S-Adenosylmethionine and has been shown in some cases to increase liver damage.
