Antinol

Antinol, daily joint supplement for dogs and cats

Antinol is a pet supplement brand that markets a daily formula for dogs and cats based on PCSO-524, a patented marine lipid complex cold-extracted from New Zealand green-lipped mussels (Perna canaliculus). The company presents the product as support for animals' everyday mobility and vitality, as well as for their skin and coat care. The brand operates in the UK market through its online store and offers a 60-day money-back guarantee.

What PCSO-524 is and where it comes from

The active ingredient in Antinol is PCSO-524, described as a concentrated oil extract rather than a conventional mussel powder. According to the brand, this complex is obtained from green-lipped mussels sustainably farmed in New Zealand waters and contains omega-3 fatty acids, including ETA, DHA and EPA, plus a broad spectrum of marine lipids. The company states that each capsule concentrates the equivalent of 15 to 18 green-lipped mussels.

The formulation was developed in New Zealand and, according to the brand, is backed by more than 25 years of research. Antinol states that it is used and recommended in veterinary clinics in the UK and other countries, and that it has distributed more than one billion capsules worldwide.

Formats for dogs and cats

The range is organised into two main lines that share the same PCSO-524 base, adapted to the daily needs of each species:

• Antinol for dogs: daily supplement in capsules; one capsule a day to support joints, coat and general vitality.
• Antinol for cats: the same PCSO-524 formula adapted for cats of all ages and breeds, including indoor cats and those with outdoor activity.

The brand also offers an Antinol Puppy Pack and starter packs for dogs and cats. According to the commercial information gathered, each starter pack includes capsules for 60 days, a free 15-day booster pack and the 60-day money-back guarantee, with free shipping.

Life stages and usage profiles

The Antinol catalogue segments the product according to the animal's life stage or activity level:

• Puppies: starting joint and coat care from the very first days.
• Active adults: support to maintain mobility at their prime.
• Seniors: daily care tailored to the needs of older animals.
• Sporting and working dogs: a formulation aimed at animals with greater physical demands.

Relationship with the veterinary and sporting environment

Antinol is presented as a product developed in collaboration with veterinary professionals and manufactured to high quality standards in New Zealand. The brand states that vets in the UK and other countries use and recommend it.

In the sporting and events field, the company identifies itself as an official partner of Crufts 2026 and runs programmes aimed at breeders, dog clubs and veterinary nursing staff, as well as sponsorships and collaborations with hydrotherapy centres and feline sanctuaries.
