My dog has regained more mobility and runs more than before. I am so happy. There is still a little pain, but the progress is good.

Skeptical at the start, I have to admit that my mixed-breed of 47 kg walks better after a month and a half. The only downside is the price!!!!

Osteoarthritis sits high on the hind paw, but the effect takes a minimum of 2 months to show. Treatment started with a half dose and then moved on to 420. That now makes 3 months of treatment in total. The effect fades when the doses are reduced, but the results are clearly there.

To help your dog move more comfortably again, PERNIXOL® combines two extraordinary marine oils, chosen to target what really matters
the root cause of stiffness
the joints' natural cushion

Found nowhere else on Earth

Patented technology
Sourced from the pristine waters of New Zealand, the green-lipped mussel oil used in PERNIXOL® stands out for its unique profile of Omega-3s and antioxidants that are naturally active and highly bioavailable.


At the origin of marine life, microalgae naturally concentrate DHA.
Grown in a controlled environment, this rare strain gives PERNIXOL® a pure, stable marine source of DHA (docosahexaenoic acid) — with zero impact on ocean biodiversity.

Every course of PERNIXOL® begins with a loading phase to build up sufficient Omega-3 reserves.

Giving PERNIXOL® is quick and easy thanks to its liquid formula and graduated pipette. Just 1ml a day helps support your dog's joint mobility.

PERNIXOL®420 is a joint supplement for dogs rich in the Omega-3 fatty acids EPA and DHA. It provides fast support for joint health in dogs weighing 20 kg or more.
Keep PERNIXOL® refrigerated

The star active ingredient in PERNIXOL®, green-lipped mussel oil, comes from a species found only in New Zealand. Packed with Omega-3s (EPA, DHA, ETA) and rare antioxidants, it is sourced from hand-selected mussels farmed in protected waters. Supercritical CO₂ extraction locks in its precious actives, renowned for supporting joint comfort.
Developed in Gironde, France, this fermented microalgae oil relies on patented technology and DHA-rich strains. Fermentation boosts their growth, while solvent-free extraction delivers up to 50% DHA. A highly concentrated source that supports healthy joints and overall well-being.
French-grown and certified organic, oleic sunflower oil is rich in Omega-9 and low in Omega-6. It is a natural source of vitamin E, helping shield the Omega-3s and keep them working at their best.
Natural vitamin E works as a preservative in PERNIXOL®, keeping the formula stable over time.
