If you have been giving your dog a joint supplement and are thinking about changing, you are in good company. Owners look for an alternative for all sorts of sensible reasons. The dog won't eat it, the label doesn't quite match what they were hoping for, or they simply want to see what else is out there.
This guide is not here to tell you which product to buy. It is here to help you compare like with like, using what each manufacturer publishes, so you can have a better conversation with your vet and make a calm, informed choice.
One thing to say from the start: a supplement supports joints and everyday mobility. It sits alongside your vet's diagnosis, a healthy weight and sensible exercise. It never replaces any of those.
Moving on from Riaflex? Start with the actives count
When owners look for a different joint supplement, the most useful thing to compare is what each formula actually declares. The table below puts that on one page, starting with a score for the six key joint actives.
MedPaw Hip & Joint Chews Max is our own product, so we have shown exactly how it measures up against five other UK options, including where they differ in format and guarantee.
Key joint actives in the UK's leading dog joint supplements

✓ = included, ✗ = not listed. Key joint actives: glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and Boswellia. Taken from each manufacturer's published information, September 2026.
The top row is the one to read first. MedPaw is the only product of the six that declares all six key joint actives: glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and Boswellia serrata. The next highest score is 4 of 6, and the rest sit at 2 or 3.
If you are switching because the mix on your current label was not quite what you hoped for, that is the gap worth closing. One daily product covers every active in the table, with omega-3, vitamins C and E and zinc alongside.
Format matters too, because a supplement only helps if your dog actually takes it. MedPaw is a soft chew many dogs treat like a snack, so there is no powder to measure or tablet to hide. There is a 60-day money-back guarantee, and Subscribe & Save if you would like a steady routine.

What owners usually mean by "alternative"
When people search for an alternative to an established joint range, they are usually in one of four situations. Knowing which one is yours makes the decision much simpler.
- They want a different format, such as a soft chew instead of a powder, tablet or capsule.
- They want a different ingredient mix.
- They want a different guarantee or way to buy, such as a longer trial or a subscription.
- They want to know whether a product suits a dog with other needs, such as a dog already on medication.
Some established ranges are built around several separate products. A typical set might include a base glucosamine and chondroitin formula, a collagen product, an omega-3 oil and an optional herbal powder. That can work well for some households, but it also means more products to buy, measure and remember. If simplicity is what you are after, a single daily product is simply a different kind of choice, not a lesser or greater one.
Think about format first
Joint supplements are given day after day for months. So the best format is often the one your dog takes reliably. A product left in the bowl does very little for anyone.
Common supplement formats and what to consider
| Format | Often suits | Worth considering |
|---|---|---|
| Powder mixed into food | Dogs that eat anything from their bowl | Fussy eaters may reject it. Dry kibble may need a little water so it sticks. Scoop measuring needs care. |
| Tablet | Dogs that take tablets easily, or owners who hide them in food | Some dogs spit them out or pick them from a meal. |
| Capsule | Owners happy to open or hide capsules | Can be fiddly for small or suspicious dogs. |
| Soft chew | Dogs that treat it like a snack | Needs counting by weight band. Keep out of reach, as dogs may think it is a treat. |
For guidance only, not a diagnosis.
A note on fussy eaters
If your dog has refused powders on kibble, a chew may feel easier to give. If your dog happily swallows a tablet in a spoonful of food, you may not need to change format at all. Be honest about what really happens at mealtimes, because that is what decides whether the routine lasts.
Compare ingredient lists, not slogans
Phrases such as "high strength" sound reassuring, but they are marketing language, not a measured standard. Some manufacturers contrast their approach with "underdosing", yet a claim like that is not independent evidence that one product works better than another. A more useful approach is to read what is actually listed.
Here are some questions to ask of any product:
- Which joint-related ingredients are listed, and are they named clearly?
- Does the pack state amounts, and does it give a feeding guide by weight?
- Is it sold as a complementary feed for dogs?
- Is the guarantee clear, and how long does it last?
Check the label, not the retailer blurb
Retailer descriptions can differ from the ingredient panel on the pack. A short product description might mention herbs that do not appear in the actual ingredient list. When the two disagree, trust the label you receive, and ask the manufacturer if anything is unclear.
Herbal ingredients need extra care
Devil's claw is a herbal ingredient found in some powders sold as joint products. Products containing it tend to carry specific cautions. The manufacturer guidance we have seen says such a product should not be given to pregnant bitches. It is also not recommended for dogs on blood thinners or with a history of stomach ulcers or irritation, and may not suit long-term use alongside NSAIDs. Vet approval is advised for dogs new to supplements or on prescription medication.
None of this means herbal products are unsuitable for every dog. It simply means a quick conversation with your vet matters most with these, before you start or switch.
How published ingredient lists differ
Going by each manufacturer's published information (September 2026), the lists vary quite a lot. The differences are factual, and none of them makes one product better than another.
- NutraPaw Joint Support is a tablet listing glucosamine, MSM, green-lipped mussel, hyaluronic acid, turmeric and collagen, with omega-3 from the mussel and manganese. It does not list chondroitin or Boswellia. It has a 90-day guarantee.
- YuMOVE Joint Support PLUS Max is a tablet listing glucosamine, green-lipped mussel, hyaluronic acid and fish oil, with chondroitin only via the mussel, plus vitamins C and E and manganese. It does not list MSM, Boswellia, turmeric or collagen. It has a 6-week guarantee.
- Seraquin Joint is a chewable tablet listing glucosamine, chondroitin and turmeric. It does not list MSM, green-lipped mussel, hyaluronic acid, Boswellia, omega-3 or collagen.
- Synoquin EFA comes as a tablet or capsule and lists glucosamine, chondroitin and krill oil, plus vitamin C and zinc.
- Nutraquin+ is a capsule listing glucosamine, chondroitin and Boswellia, plus vitamin C and zinc.
For Seraquin, Synoquin EFA and Nutraquin+, no guarantee is stated in the information we have. Seeing the lists side by side shows why "which is best" is the wrong question. A better one is "which combination of ingredients, format and terms suits my dog and my routine".
Where MedPaw Hip & Joint Chews Max fits
MedPaw Hip & Joint Chews Max is a daily soft chew, sold as a complementary feed for dogs. It is made to support healthy joints and everyday mobility, alongside veterinary care.
Its joint-related ingredients are glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and Boswellia serrata. It also contains omega-3 from green-lipped mussel and flax seed, vitamins C and E, and zinc, and it is made with rapeseed oil and glycerine.
Comparing it fairly with the lists above, here are the factual differences:
- MedPaw lists chondroitin as a direct ingredient. NutraPaw does not list it, and YuMOVE includes it only via the mussel.
- MedPaw lists Boswellia serrata. Among the products above, Nutraquin+ also lists it.
- MedPaw lists MSM, as does NutraPaw. The other products above do not list it.
- MedPaw is a soft chew. The others above are tablets, a chewable tablet or capsules.
It does not contain devil's claw, so it is a different kind of product from a herbal powder, not a like-for-like swap.
Feeding guide
The amount depends on your dog's weight. Follow the pack rather than guessing.
- Up to 4kg: 1 chew a day
- 5 to 17kg: 2 chews a day
- 18kg and over: 2 to 3 chews a day
The amount is doubled for the first three weeks. We recommend daily use for 2 to 3 months, so it suits owners who are happy to build a steady routine rather than expect quick changes. There is a 60-day money-back guarantee, and Subscribe & Save is available if you would rather not reorder each month.
Switching sensibly: a few practical steps
Changing supplements is simple when you take it calmly. These steps make it easier to see how your dog is getting on.
- Speak to your vet first. This matters most if your dog takes prescription medication, is pregnant or nursing, or has a medical history.
- Write down what your dog takes now. Note the product, the daily amount and how long they have been on it.
- Change one thing at a time. If you switch supplement, diet and exercise together, you will not know which one made the difference.
- Give it time. Joint supplements are a steady, daily part of a routine rather than an overnight change, and each product has its own guide, so follow the pack.
- Keep a simple mobility diary. Once a week, jot down how your dog manages stairs, getting up after rest, walk length and mood. Short videos of your dog moving can help your vet too.
Support the basics alongside any supplement
Whichever product you choose, the everyday basics do a great deal of the work, as our complete guide to dog joint health explains. Many of them cost very little to put in place.
- Keep your dog lean. Extra weight adds load to the joints, and your vet can help you set a realistic target.
- Offer steady, lower-impact exercise. Several short walks are usually kinder than one long weekend outing.
- Make the home easier to move around. Non-slip flooring, a supportive bed, and ramps or steps for the car and sofa all help.
When to see your vet
A supplement should never delay a vet visit. If you notice any of the signs below, book an appointment rather than waiting to see whether a new product helps.
How quickly to act on changes in your dog
Mild, occasional stiffness
Slow to get going after rest, or a little hesitant on stairs. Mention it at the next check-up and start your mobility diary.
Regular or worsening signs
Limping, reluctance to jump or climb, licking at a joint, or changes in mood or gait. Book a vet appointment soon.
Sudden or severe signs
Sudden or severe lameness, yelping when touched, a hot or swollen joint, or refusing to move. Call your vet promptly.
It is also sensible to check with your vet before giving any supplement if your dog is on NSAIDs or other prescription medicines, has a history of stomach ulcers or digestive upset, is pregnant or nursing, or has an existing health condition.
If your dog develops vomiting, diarrhoea, loss of appetite or any other unusual reaction after starting a new product, stop it and call your vet. Choosing an alternative is a perfectly reasonable thing to do. With a clear view of format, ingredients, guarantee and your vet's advice, you can make the decision with confidence.
Why do owners look for a Riaflex alternative?
The usual reasons are format, ingredient mix, the length of the guarantee and how the product is bought. Some dogs simply take one format more reliably than another. Check Riaflex's own UK product page for its current composition and feeding guide, then compare it with other labels like for like.
What are the main joint supplement alternatives available in the UK?
Going by each manufacturer's published information (September 2026), options include NutraPaw Joint Support (tablet), YuMOVE Joint Support PLUS Max (tablet), Seraquin Joint (chewable tablet), Synoquin EFA (tablet or capsule) and Nutraquin+ (capsule). MedPaw Hip & Joint Chews Max is a daily soft chew. Their ingredient lists differ, so read each label rather than relying on a headline claim.
How does MedPaw Hip & Joint Chews Max differ from tablets and capsules?
It is a soft chew, sold as a complementary feed for dogs to support healthy joints and everyday mobility. It lists glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and Boswellia serrata, plus omega-3 from green-lipped mussel and flax seed, vitamins C and E, and zinc. It has a 60-day money-back guarantee, and Subscribe & Save is available.
How many MedPaw chews does a 20kg dog need, and how long does a tub last?
For dogs of 18kg and over, the label says 2 to 3 chews a day, doubled for the first three weeks. At 20kg that means 4 to 6 chews a day at first, so a 60-chew tub lasts roughly 10 to 15 days. After that, 2 to 3 chews a day makes a tub last 20 to 30 days. Daily use for 2 to 3 months is recommended, and the pack guide always comes first.
If my dog is doing well on Riaflex, should I switch anyway?
Not necessarily. If your dog takes it reliably, the format suits your routine and your vet is happy with it, there may be no reason to change. A switch makes more sense if the dog refuses it, or the label or terms no longer suit you. If you do change, alter one thing at a time and keep a simple mobility diary.
Do I need to speak to my vet before changing my dog's joint supplement?
Yes, it is sensible to check first, especially if your dog takes prescription medicines such as NSAIDs, has a history of stomach problems, is pregnant or nursing, or has a health condition. A supplement never replaces veterinary care. If your dog is limping, struggling to get up or seems in discomfort, book a vet appointment rather than waiting to see whether a new product helps.
