Why New Zealand Green Lipped Mussel is incredibly powerful
The Māori Secret
In the 1970s, researchers noticed something strange. Coastal Māori people in New Zealand had virtually no arthritis – even into old age. Inland Māori and Europeans did. The only difference? Coastal Māori ate raw green lipped mussels daily. This discovery launched decades of research.
Found Nowhere Else On Earth
The Green Lipped Mussel (Perna canaliculus) is endemic to New Zealand. It cannot be farmed or replicated anywhere else. The mussels grow in the Marlborough Sounds – fed by nutrient-rich currents flowing directly from Antarctica. Each mussel filters 360 liters of this pristine seawater every single day.
Contains A Compound Fish Oil Doesn’t Have
While fish oil contains 2–3 omega-3s, Green Lipped Mussel contains over 30 – including ETA, a rare omega-3 found in no other marine source. ETA works at the gene level to block inflammation, making it hundreds of times more potent than the EPA in fish oil.

Ingredients come first
Every single ingredient in the tub is added with one purpose: To get your grip on IVDD as fast as possible and keep them mobile long term. Making sure IVDD episodes never return or never happen. All ingredients are added in the most bioavailable and nutrient rich form: Unlike all other brands that use cheap synthetic glucosamine in too low doses.
What’s inside GLM
- ETA Omega-3 – A rare fatty acid that blocks inflammation at the source. Works like prescription pain meds, without the side effects.
- EPA & DHA – The omega-3s that calm swelling and soothe the sore spine.
- Glycosaminoglycans (GAGs) – Rebuilds worn discs and provides the “oil” needed to keep everything moving smooth.
- Natural Chondroitin – Acts like a cushion between bones so movement doesn’t hurt.
- Vitamins & Minerals – Zinc, copper, manganese, and vitamins E & C to help the body repair faster.
- Carotenoids & Antioxidants – Protects discs from further damage and slows down wear and tear.

Simple, 30-second ritual
So easy even your dog will remind you
Used by 8,000+ dog owners with amazing results
Powder – every morning
Sprinkle the powder on your dog’s food every morning. One scoop for dogs under 35 lbs, two scoops for larger dogs. The powder is tasteless – most dogs don’t even notice it. Mix it into wet food or sprinkle on kibble.
Consistency – daily use
Use it daily for best results. The Green Lipped Mussel builds up in your dog’s system over 2–4 weeks. Don’t skip days during the initial period. After 4 weeks, you can reduce to every other day for maintenance.
No other supplements needed
Don’t waste money on other supplements. The PetFormulary powder contains everything your dog needs – Omega-3s, Glucosamine, Chondroitin, and GAGs. Adding more supplements won’t speed up results and may upset your dog’s stomach.
The Science
Pubmed has over 200+ studies about Green Lipped Mussel for IVDD. It has been used in traditional medicine for 100s of years. Some results from 3rd party studies:
showed improved mobility
(vs. only 7% in the control group)
had less stiffness and pain
after 4 weeks
were significantly more active
after 60 days
The Proof
I was skeptical at first, but after just 2 weeks I noticed Rosie was greeting me at the door again. By week 4, she was walking around the house like she used to. By week 6, she jumped on the couch for the first time in months. I wish I had found this sooner.

“I can finally sleep in peace now!”

We're about 2 weeks in and I'm already seeing him get up easier in the mornings. He used to just lay there until I helped him. Now he's up on his own. Cautiously optimistic but this is more progress than we saw with the chews after 2 months.
Ollie has had two IVDD episodes and after the second one I was terrified of a third. Three weeks into this and he walked up the stairs on his own for the first time in months. I stood there and just cried.
My dachshund Pepper was dragging her back legs after her last flare up. We added this at week two. By week four she was walking on her own again. The difference from where she was is night and day.
My Corgi is only three and the vet told me he is already at high risk because of his build. No episode yet but I started this as a preventative measure two months ago. The stiffness he had after long walks is basically gone.
Real customers, real results
Finally walking normally again
Started this after our second IVDD scare. Six weeks in and he's moving like he did two years ago. I don't say that lightly.
My vet asked what changed
She noticed the difference at his checkup before I told her anything. Asked me what I'd changed. That was all the proof I needed.
Worth every penny
Tried three other supplements before this. The chews did nothing for months. This one I could see working by week three.
He jumps on the couch again
Small thing but it means everything. He hadn't done it in almost a year. Now he does it every evening like nothing happened.
Easy to give, no fuss
Just goes on the kibble. He doesn't even notice it's there. I was worried about that because he's incredibly picky.
Second tub already
Ordering my second one. Not stopping this. The mornings are completely different now, he gets up on his own.
Started as prevention
Her breed puts her at risk so I started before anything happened. Two months in and she's noticeably more fluid after long walks.
Real difference by week four
Nothing happened the first two weeks and I nearly gave up. Glad I didn't. Week four is when it clicked.
Less stiffness in the mornings
The stiff first few steps are basically gone. That was the thing that worried me most and it's the first thing that improved.

Great for a senior dog
I was so skeptical because we tried everything for our dachshund. Glucosamine chews did nothing. This is the first thing that actually worked to get her walking again.
Like · Reply · 3mMy 3 year old Frenchie was struggling to get up in the mornings. Started this 3 weeks ago and yesterday he ran to the door when the mailman came. Haven't seen him do that in over a year.
Like · Reply · 8mJust ordered my 3rd jar. My vet noticed the difference before I even told her what I was giving him. She asked what changed because his mobility improved so much. That says everything
Like · Reply · 12mMy sweet girl is 14 and I thought her slowing down was just age. Tried this because my neighbor recommended it for her dog. 2 weeks in and she's back to following me around the house again.
