Protexin Denamarin. High level support for the liver.

Denamarin provides multi-faceted high level nutritional support for the liver due to its synergistic combination of S-adenosylmethionine (SAMe) and silybin.

Denamarin contains:

A stabilised form of the S,S-SAMe isomer, the predominant form synthesised in cells and the isomer which is biologically active
Silybin complexed with phosphatidylcholine, which has been shown to be more bioavailable than silymarin alone.

The enteric coating of Denamarin protects the SAMe from degradation. Denamarin is also blister packed to prevent oxidation of the SAMe to the non-biologically active R,S-SAMe isomer. The product is manufactured to high quality standards to ensure the label claim is met.

Denamarin is available in three sizes to make it easy to give to your cat or dog:

For cats and small dogs up to 5kg
For medium dogs 5-15kg
For large dogs over 15kg.

Directions for use:

Weight Cats and Small Dogs Medium Dogs Large Dogs
<5kg 1 tablet    
5-15kg   1 tablet  
15-30kg     1 tablet
30-55kg     2 tablets
>55kg     3 tablets

Tablets should be given on an empty stomach at least one hour before a meal for optimum absorption (an overnight fast is preferred). The number of tablets administered may gradually be reduced, or increased, at any time at the recommendation of your veterinary surgeon.

Store in a cool, dry place. Keep tablets in original blister pack until used. The tablets should not be split or crumbled.

Protected my dog’s liver function throughout her chemotherapy. Very slow to digest and rather a difficult size, but my dog got into a routine of taking them and they did the job.

I can only reiterate what I have said when reviewing previously. An excellent product which I am sure has played a major part in keeping Ben going for the last four years.

Four years since diagnosis, Ben is still going strong, having had these tablets throughout. They used to make chewable, but I haven't been able to get them for some time, so have use these instead- hence only good rather than excellent.
