Antinol
Antinol is a vet-channel joint and mobility supplement for dogs and cats built around PCSO-524, a stabilised green-lipped mussel lipid extract, now paired with krill oil in the upgraded EAB-277 blend sold as Antinol Plus (the successor to the original PCSO-524 capsule and the interim Antinol Rapid). It is a single-purpose marine-lipid soft-gel rather than a broad multi-ingredient joint formula, with a genuine peer-reviewed evidence base behind the active. In Australia it is sold mainly through the brand's own website on subscription, through vet clinics and pet pharmacies, and via Pet Circle. It sits at the premium end of the joint-supplement shelf on price.

Antinol is a strong choice if…
- ✓Dogs and cats needing focused daily joint and mobility support
- ✓Owners who prefer a clean, single-active marine-lipid supplement over multi-ingredient blends
- ✓Pets that struggle with tablets, via the Easy-Feed cut-and-squeeze capsules
May not be the best fit if…
- —You want the lowest cost-per-day and are comparing against value joint chews
- —You prefer a broad multi-ingredient joint stack with glucosamine, chondroitin and green-lipped mussel combined
