Best Joint Supplements for Dogs in the UK, Compared

Last updated: 31 October 2026

Some links on this page are affiliate links. We earn commission on Your Pet Nutrition products (Canine Prime and Flexi Protect) at no extra cost to you, and it hasn’t changed how we rank them. This guide is general information and isn’t a substitute for advice from your vet.

Joint supplements cost anything from under 10p to £4 a day, and most brands don’t make it easy to compare them. We compared 8 that are widely sold in the UK on what they cost for your dog’s weight, how much of each ingredient they contain, and what the research says those ingredients do.

How we compared them: we haven’t tested these on our own dogs. We used each brand’s published feeding guide, ingredient amounts and prices, checked on 31 October 2026, and published veterinary research. No brand paid to be included.

Our picks

Best for most dogs: YuMOVE Joint Support for Adult Dogs
Published amounts of green-lipped mussel and glucosamine, easy to buy, and good value on its bulk subscription. From £0.48 a day for a 17kg dog.
Best evidence: Antinol Joint Care Pro
The only product here with an independent published trial in dogs with arthritis. From £0.48 a day for a 17kg dog.
Best budget vet brand: Seraquin for dogs
Cheapest per day of the vet brands, with high published doses, though its main ingredients have the weakest evidence. From £0.33 a day for a 17kg dog.
If your dog won’t take tablets: Pet Gently Joint Care Dog Chews
A soft chew with published amounts of green-lipped mussel, glucosamine and chondroitin. From £0.72 a day for a 17kg dog.
Best all-in-one: Canine Prime
If you want joints, digestion and coat covered in one daily scoop. It doesn’t publish its joint ingredient amounts, so if joints are your main concern, a dedicated supplement is better value. From £1.40 a day for a 17kg dog. See Canine Prime vs YuMOVE.

What will it cost for your dog?

Bigger dogs need more tablets or chews, so the cheapest product for a terrier isn’t always the cheapest for a Labrador. Enter your dog’s weight to see the daily cost of each one.

What’s in them

Three of the eight don’t publish how much of each ingredient they contain, so you can’t tell whether a dose is meaningful. Here’s what a 17kg dog gets each day from the rest.

Per day, 17kg dog	Dose	Green-lipped mussel	Glucosamine	Chondroitin
YuMOVE Joint Support for Adult Dogs	2 tablets	300mg	500mg	Not published
Antinol Joint Care Pro	1 capsule	50mg as concentrated oil	None	None
Seraquin for dogs	1 tablet	Not published	500mg	380mg
Synoquin EFA	1 tablet	Not published	Not published	Not published

Flexi Protect	4 chews	Not published	Not published	Not published
Joint Aid for Dogs	5g	None	120mg	None
Canine Prime	1½ scoops	Not published	Not published	Not published

Antinol uses a concentrated oil extracted from green-lipped mussels, so its 50mg isn’t comparable with the mussel powder in the others. YuMOVE’s figure is its ActivEase blend of green-lipped mussel and hoki fish oil.

What the evidence says

Joint supplements aren’t regulated like medicines, and the research behind their ingredients varies a lot. A 2022 review and meta-analysis of the studies on diets and supplements for arthritis in dogs and cats is the most thorough summary so far.

Omega-3 has the best evidence. Fish oil (EPA and DHA) and green-lipped mussel came out best. Canine Arthritis Management, a UK vet-led group, says green-lipped mussel needs a high dose and 2 to 3 months to work.
Glucosamine and chondroitin have the weakest. The review found they didn’t relieve pain, and said they should no longer be recommended for pain relief, even though they’re in most joint supplements.
Turmeric is unproven. The one controlled study in dogs found no measurable effect.

So when comparing products, look for green-lipped mussel or omega-3 with a published dose, rather than the longest ingredient list. None of the products here contains enough omega-3 to match the amounts used in fish oil studies. If your vet recommends omega-3, a dedicated fish oil such as a Scottish salmon oil (affiliate link) may be the simplest way to get it.

Supplements don’t replace a vet. If your dog is limping, stiff after rest or slowing down on walks, see your vet. Keeping your dog slim, regular gentle exercise and pain relief where needed make more difference than any supplement.

How to choose

Talk to your vet first if your dog is already stiff or limping, so any pain is treated.
Look for published doses. If a brand won’t say how much is in it, you can’t compare it.
Prioritise green-lipped mussel or omega-3, which have the best evidence.
Work out the cost for your dog’s weight, including any loading dose, using the calculator above.
Pick a format your dog will take every day: a supplement only works if it gets eaten.
Give it 6 to 12 weeks, note how your dog moves before you start, and use the money-back guarantee if there’s no difference.

Frequently asked questions

Do joint supplements for dogs work?

Some do, for some dogs. The strongest evidence is for omega-3 fatty acids, including green-lipped mussel. A 2022 review of the research found glucosamine and chondroitin did not relieve pain and said they should no longer be recommended for pain relief. Supplements work best alongside weight control, regular exercise and any pain relief your vet prescribes, not instead of them.

What is the best joint supplement for dogs in the UK?

For most dogs we’d choose YuMOVE Joint Support: its doses are published, it contains green-lipped mussel, and it costs about £0.48 a day for a 17kg dog on its bulk subscription. Antinol has the best independent evidence. Seraquin is the cheapest vet brand. Use the calculator above to compare costs for your dog’s weight.

How long do joint supplements take to work?

Give any joint supplement at least 6 weeks, and green-lipped mussel 2 to 3 months, before deciding whether it helps. Keep a note of how your dog moves now, for example how easily they get up or manage the stairs, so you’re not relying on memory.

Can I give a joint supplement with Metacam, Librela or other arthritis medicine?

Joint supplements are generally considered safe to give alongside prescribed pain relief, and many vets recommend both. Tell your vet which supplement you’re using, especially if your dog has a health condition, a shellfish allergy or takes other medicine.

Is there a cheaper alternative to YuMOVE?

Seraquin and Joint Aid for Dogs both cost less per day, but they contain different ingredients and no green-lipped mussel. YuMOVE itself is much cheaper per tablet on its 300-tablet subscription than on a single pack, so that’s worth checking first.

Is Canine Prime good for joints?

Canine Prime contains glucosamine, chondroitin and green-lipped mussel, but it’s an all-in-one supplement and doesn’t publish how much of each it contains. If joints are your main concern, a dedicated joint supplement is better value. See our Canine Prime vs YuMOVE comparison.
