Antinol® is a fast-acting formula that, when taken daily, will help your pet maintain an active lifestyle and help support their joint metabolism.

  • Where is Antinol® manufactured?

    Vetz Petz®︎ Antinol®︎ is manufactured in New Zealand from Perna canaliculus (the Green Lipped Mussels).

  • Does Antinol® have any side effects or allergic reactions?

    Antinol®︎ is safe for long-term daily use.

    Side effects from Antinol® are rare, so if you see any symptoms in your dog/cat, please consult a veterinary surgeon. Rare symptoms may include gastrointestinal signs such as diarrhoea or vomiting. As the capsules are made of gelatin derived from beef, we recommend that you give only the internal contents (the oil) to a dog/cat that is allergic to beef or cow products and not the external soft gel capsule. If you think your pet is having an allergic reaction please consult your vet immediately. Antinol® is made with fatty acids from shellfish (mussels), and though the possibility of an allergic reaction is low, please do not give Antinol® to your dog/cat if you know they are allergic to shellfish. If you have any concerns, please consult a veterinary surgeon.

  • How quickly will I see a difference in my pet?

    Each pet is different! Changes can be seen as early as 3 to 4 days after starting Antinol, but most pet owners will notice a difference within 15 days of use. Sometimes it can take up to 60 days to see the full beneficial effects of Antinol.This may vary depending on the individual situation of your cat or dog, so we recommend that you continue to give Antinol and monitor your pet for 60 days. For the first 15 days, we recommend that you feed double the normal amount of Antinol to reach the appropriate nutritional level.
