Four jobs, one chew
What the formula is actually doing
Glucosamine, type II collagen and chondroitin — what cartilage is actually made of.
Boswellia at 65% boswellic acids and turmeric at 95% curcuminoids.
Hyaluronic acid and green-lipped mussel, for the fluid the joint glides on.
Piperine alongside the curcumin, because curcumin alone barely absorbs.
Eleven actives. Every one on the label.
Most joint tubs declare two or three and hide the rest inside a blend total. Here is what is in the chew that the front of the pack usually leaves out.
Remaining actives: glucosamine 200 mg, green-lipped mussel 150 mg, boswellia serrata 75 mg, turmeric extract 60 mg, vitamin C 30 mg, vitamin E 2 mg. All amounts per 3 g soft chew.

The headline six
Standardised extracts, not raw powders
A label that says “turmeric” and a label that says “turmeric extract, 95% curcuminoids” are selling you two completely different things.
200 mg
Glucosamine
Raw material for cartilage and joint fluid.
- Declared, not hidden in a blend
- Shellfish-derived
150 mg
Green-lipped mussel
Marine source of omega-3s and glycosaminoglycans.
- Almost never included at this level
- Works alongside the glucosamine
60 mg
Turmeric extract
Standardised to 95% curcuminoids — not the 3% kitchen spice.
- Paired with piperine for absorption
- An ingredient, not a decoration
75 mg
Boswellia serrata
Standardised to 65% boswellic acids.
- Supports a normal inflammatory response
- Absent from most competing chews
30 mg
Vitamin C
Cofactor the body needs to synthesise collagen at all.
- Supports the collagen in the same chew
- Antioxidant role alongside vitamin E
2 mg
Vitamin E
Antioxidant support for tissue under repetitive load.
- d-alpha-tocopheryl acetate
- Also keeps the chew stable
Other ingredients: inactivated brewer’s yeast, potato starch, vegetable glycerin, dried apple pomace, tapioca flour, refined coconut oil, hydrolyzed animal protein, sorbic acid, flaxseed meal, tocopherol extract. Contains shellfish. No corn, wheat or soy. Ingredient photography is illustrative.
Side by side
Against a typical joint chew
| Typical drugstore chew | Mobility Plus | |
|---|---|---|
| Glucosamine | 100–250 mg, often unstated | 200 mg, declared |
| Green-lipped mussel | Almost never included | 150 mg |
| Type II collagen | Rare outside premium tiers | 100 mg |
| Boswellia | Absent | 75 mg at 65% boswellic acids |
| Hyaluronic acid | Rare | 10 mg, high molecular weight |
| Actives declared | Two or three at best | Eleven, every one in mg |
Comparison is against commonly sold joint chews in the US market. Read the label of whatever you are comparing — if the amounts are not printed, that is the answer.
Why Mobility Plus works
Five mechanisms, and the ingredient doing each job.
Rebuilds the cartilage matrix
Cartilage is largely glucosamine, chondroitin and type II collagen. The body makes all three, just more slowly each year while the load stays the same. This supplies all three at declared amounts rather than one of them at a token level.
Supports a normal inflammatory response
Boswellia at 65% boswellic acids and turmeric at 95% curcuminoids. Worn cartilage irritates the joint capsule, which inflames, which wears cartilage faster — this is the part of the loop nutrition can reach.
Thickens the fluid the joint glides on
Hyaluronic acid gives synovial fluid its viscosity, and it declines with age. Green-lipped mussel brings glycosaminoglycans and marine omega-3s alongside it.
Absorption engineered in, not assumed
Curcumin on its own absorbs poorly, so there is piperine next to it. Vitamin C is there because collagen synthesis does not happen without it. The formula accounts for what the body does with the ingredients, not just what is in the tub.
Nothing hidden inside a blend
Eleven actives, eleven milligram figures. If a competitor will not tell you the amount, you cannot compare it — and that is usually the point.
Veterinary input
Reviewed by a vet. Not fronted by one.
Our formulas are reviewed by a practising veterinarian before they go to manufacture. She has asked not to be named publicly, and we are not going to invent a face or a quote in her place. What we can show you is the part you can actually check.
Amounts, interactions and contraindications, looked at by a practising vet before the batch is made.
Printed on the label, so your own vet can read it in thirty seconds and tell you what they think.
Email us the code on your tub and we send that batch's analysis - potency, heavy metals, microbials.
Sudden lameness, one leg only, worse week over week: that is a diagnosis. It is in the FAQ below, not buried.
We would rather show you a label you can verify than a testimonial you cannot.

Daily directions
Given with food, once a day
The doubled amount over the first four to six weeks builds tissue levels faster. After that you stay on the maintenance amount for good.
- Up to 25 lb 1 chew a day. Give 2 a day for the first 4 to 6 weeks, then drop to 1.
- 26 to 50 lb 2 chews a day. Give 4 a day for the first 4 to 6 weeks, then drop to 2.
- 51 to 100 lb 3 chews a day. Give 6 a day for the first 4 to 6 weeks, then drop to 3.
- Over 100 lb 4 chews a day. Give 8 a day for the first 4 to 6 weeks, then drop to 4.
Day to day
Where this shows up in everyday life
The rise after a nap is usually the first thing owners notice, somewhere in week four to six.
The half-second pause at the bottom of the stairs is the clearest early marker, in both directions.
The day after a long walk matters as much as the walk. That gap is where most owners see the change.
Brewer’s yeast base, taken from the hand by most dogs. No capsule to hide in cheese.
From under 25 lb to over 100 lb, the label tells you exactly how many and for how long.

The honest version
What to expect, and when

Boswellia and turmeric may take the edge off sooner, but the structural work has not started. This is the stage most owners quit on.

Less hesitation on stairs, shorter recovery after activity. The first changes an owner actually reports.

Collagen and hyaluronic acid reach the levels that matter. This is the dog offering to walk further.
This is the pattern and the biology behind it, not a guarantee for your dog. Maintenance slows the decline; stopping means starting the clock again.

Before you buy
Frequently asked questions
Can I give both?
No — you would be doubling the same actives. Pick one.
My dog is on an NSAID from the vet.
Talk to them before adding this. Boswellia and turmeric act on the same pathway, and that is a conversation for the person who wrote the prescription. Every amount is printed on our label, so take it to the appointment.
When should I see a vet instead?
Lameness that came on suddenly, affects one leg only, or is getting worse week over week is a diagnosis — a cruciate tear, an infection, an injury. A supplement does not address any of those, and starting one instead of booking the appointment costs your dog time.
How long does a tub last?
For a 50 lb dog on maintenance: 30 days for the 60-count, 60 days for the 120-count. The first four to six weeks go through it twice as fast, because of the doubled starting amount.
Allergens?
Contains shellfish (green-lipped mussel). No corn, wheat or soy. Not for pregnant or lactating dogs. If your dog has a diagnosed food allergy, check the full ingredient list above before starting.
