YuMOVE vs Seraquin for Dogs: A UK Vet's Honest Ingredient-by-Ingredient Comparison

Author: Dr Rebecca Massie MRCVS, Practising UK Veterinary Surgeon

YuMOVE vs Seraquin: Which Dog Joint Supplement Is Actually Better?

Both YuMOVE and Seraquin are widely used in UK vet clinics and both contain real, evidence-backed ingredients. YuMOVE PLUS delivers glucosamine, Green-Lipped Mussel and hyaluronic acid in a tablet. Seraquin offers higher raw glucosamine and chondroitin doses, plus turmeric, also in tablet form. Neither addresses gut health - and that is the gap that limits how much of either product your dog actually absorbs.

Why YuMOVE and Seraquin Both Land on UK Vet Desks

In my practice, two joint supplement names come up constantly: YuMOVE and Seraquin. Both are stocked in vet clinics, both have loyal followings, and both are backed by genuine science on their key ingredients.

But when a client asks me which one to choose, I find myself giving the same answer every time. Not because the question is easy, but because the most important issue is one neither product addresses at all.

Before I get to that, let me walk you through exactly what each product contains, what the research supports, and where each one leaves a gap. This will be a proper ingredient-level comparison - not a marketing summary.

If you want broader context first, our guide to dog joint supplements and the gut-joint axis covers the full landscape in detail.

What Is Seraquin for Dogs - Ingredients, Doses and Fillers

Seraquin is manufactured by Boehringer Ingelheim Animal Health UK Ltd and has been stocked in veterinary practices for years. It is available in two sizes: an 800mg tablet for cats and dogs under 10kg, and a 2g chewable tablet for dogs over 10kg.

The 2g tablet - the version most commonly used for medium and large dogs - contains the following per tablet: Glucosamine HCl 500mg, Sodium Chondroitin Sulphate 380mg, and Turmeric Extract 50mg. The full ingredient list also includes inactivated yeast (Saccharomyces cerevisiae), maltodextrin, hydrolysed chicken protein, pork liver flavouring, sodium chloride, and calcium stearate as a binder.

Dosing for a 30kg dog: 2 tablets daily (maintenance), doubled for the first 4 to 6 weeks as a loading dose.

Seraquin's differentiating claim has always been turmeric. Boehringer Ingelheim positions the curcuminoids in turmeric as natural antioxidants that counteract free-radical-mediated cartilage breakdown - which is a legitimate mechanism with real research behind it. I will come back to the caveats on that.

What Seraquin does not contain: no Green-Lipped Mussel, no omega-3 fatty acids, no hyaluronic acid, no probiotics, no prebiotics, no postbiotics, and no gut support of any kind.

What Is YuMOVE for Dogs - Ingredients, Doses and Fillers

YuMOVE is produced by Lintbells, now trading as Vetnique, a company that acquired the brand from private equity firm Inflexion in 2024. It has been the UK's most recommended joint supplement brand by veterinary volume for a number of years. The range has multiple tiers - for this comparison I am using YuMOVE Joint Care PLUS, which is the higher-strength formula and the one most commonly recommended for dogs with established stiffness.

YuMOVE Joint Care PLUS contains per tablet: Glucosamine HCl 250mg, Green Lipped Mussel Powder (containing Natural Chondroitin) 180mg, N-Acetyl-D-Glucosamine 20mg, Hyaluronic Acid 2mg, Manganese Sulphate 3mg, Vitamin C 12.5mg, and Vitamin E 1mg. The composition also lists Dicalcium Phosphate, Fish Powder, Magnesium Stearate, and Sunflower Oil as part of the tablet matrix.

Dosing for a 30kg dog: 4 tablets daily (maintenance), doubled for the first 4 to 6 weeks.

YuMOVE's key ingredient is its proprietary ActivEase Green-Lipped Mussel - a concentrated GLM extract processed using a patented drying method that Lintbells claims preserves a broader spectrum of Omega-3 fatty acids than standard GLM powder. This is the science that underpins the brand's clinical study at the Royal Veterinary College, which demonstrated significant improvement in joint mobility at 6 weeks.

What YuMOVE does not contain: no probiotics, no prebiotics, no postbiotics, and no gut support of any kind.

YuMOVE vs Seraquin: Full Ingredient Comparison for a 30kg Dog (e.g. a Labrador or Golden Retriever)

I am using a 30kg dog as the reference point - the most clinically relevant weight for the large UK breeds most likely to need joint supplementation: Labradors, Golden Retrievers, German Shepherds, and Springer Spaniels. At this weight, Seraquin requires 2 tablets, YuMOVE PLUS requires 4 tablets, and Juno Daily requires 2 scoops daily. Here is what each product delivers.

Glucosamine: Seraquin delivers 1,000mg as HCl. YuMOVE PLUS delivers approximately 1,080mg of glucosamine-type compounds across 4 tablets. Juno Daily delivers 600mg of pure bioavailable glucosamine powder.

That gap requires an explanation - and it is actually evidence of the problem with tablet supplements, not a weakness in Juno's formula. A 2016 study in the Journal of the American Animal Hospital Association (Maxwell et al.) showed that tablet glucosamine formulations delivered only 38% to 56% of the peak plasma concentration achieved by a powder or liquid equivalent. Tablet manufacturers compensate by loading far more raw glucosamine into the dose than will ever reach the bloodstream. Juno's 600mg is delivered in a format with no compression losses, no binders slowing dissolution, and a full pre-, pro- and postbiotic system actively maintaining the gut environment that absorbs it. In practice, 600mg of pure bioavailable powder may well deliver more to your dog's joints than 1,000mg compressed into a tablet with maltodextrin and calcium stearate.

Chondroitin: Seraquin provides 760mg sodium chondroitin sulphate directly. YuMOVE provides chondroitin within its 360mg GLM powder - the exact fraction is not separately quantified. Juno Daily delivers 300mg as pure powder. Research published in the American Journal of Veterinary Research (2019) found oral bioavailability of chondroitin in dogs at 4.8% to 5% for single tablet doses - meaning the headline figures for both tablet products substantially overstate what is absorbed. Juno's 300mg in powder format, supported by a healthy gut environment, may deliver comparable effective chondroitin to a considerably higher tablet dose.

Anti-inflammatory support: YuMOVE's ActivEase GLM contains omega-3 fatty acids including ETA, which has real research behind it for joint inflammation. Seraquin uses standard turmeric extract (100mg curcuminoids across 2 tablets) - a legitimate mechanism with a significant bioavailability caveat I will return to. Juno delivers 200mg Omega-3 DHA plus 1,000mg Spirulina, a natural antioxidant and immune-support layer with no absorption limitations from a tablet matrix.

Joint lubrication: YuMOVE PLUS contains 8mg Hyaluronic Acid across 4 daily tablets. Seraquin contains none. Juno Daily contains none.

Gut support: Neither Seraquin nor YuMOVE contains any. Zero. In both products. I will explain why this is the most important thing missing from both formulas.

*Juno's glucosamine and chondroitin figures are lower on the label because they do not need to compensate for tablet absorption losses. Research shows tablet glucosamine formulations deliver only 38-56% of the peak plasma concentration achieved by powder equivalents (Maxwell et al., JAAHA 2016). A pure active powder with an intact gut-support system means more of every milligram actually reaches your dog's joints.

To understand what glucosamine and chondroitin actually do at a structural level, our article on what chondroitin does for dogs covers the molecular detail - as does our guide to glucosamine for dogs, including the bioavailability issue that affects both products equally.

What Does the Clinical Research Actually Say About These Ingredients?

I want to be careful here. Good marketing can make the line between "evidence supports this ingredient" and "this specific product is clinically proven" look much thinner than it is. Let me take each key ingredient in turn.

Green-Lipped Mussel (YuMOVE): The evidence for GLM in canine osteoarthritis is reasonably solid. Randomised controlled trials have demonstrated improvements in veterinarian-assessed mobility and pain scores compared to placebo in dogs with radiographic OA. GLM is not a painkiller and does not act quickly - it supports the body's own processes over weeks and months. YuMOVE also has a specific Royal Veterinary College study supporting its particular ActivEase formulation. This is one of the stronger evidence bases in the UK supplement market.

Turmeric / Curcumin (Seraquin): Curcumin has genuine anti-inflammatory and antioxidant properties, and there is research supporting its use in canine osteoarthritis - including a study published in PMC (PMC8162585) demonstrating that a phytosomal form of curcumin (CurcuVet) reduced pro-inflammatory cytokines including TNF-a and IL-1b in arthritic dogs. However, the crucial caveat is bioavailability. Standard curcumin has notoriously poor oral absorption due to low aqueous solubility and rapid metabolism. The phytosomal formulations used in clinical research significantly outperform standard turmeric extract in terms of bioavailability. Seraquin uses a standardised turmeric extract at 50mg per tablet - not a phytosomal complex. The clinical benefit of 50mg of a standard turmeric extract at this dose level has not been independently established in peer-reviewed canine studies to my knowledge.

Glucosamine and Chondroitin (both): The research picture here is well-established but nuanced. A 2016 study published in the Journal of the American Animal Hospital Association (Maxwell et al., DOI: 10.5326/JAAHA-MS-6267) demonstrated that liquid glucosamine formulations produced significantly higher peak plasma concentrations than tablet formulations in dogs. The dose-normalised maximum plasma concentration for liquid was 5.5 micrograms per ml, compared to 3.1 and 2.1 for the two tablet formulations tested. In other words, tablet binding agents and the compression process itself reduce how much active ingredient reaches the bloodstream.

For chondroitin, research published in the American Journal of Veterinary Research (2019) found oral bioavailability in dogs for single doses ranges from 4.8% to 5%. That means for every 760mg of chondroitin across 2 daily Seraquin tablets, your dog may absorb as little as 36 to 38mg. This is not a reason to stop using chondroitin - cumulative effects with repeated dosing have been reported - but it is a reason to think carefully about the gut environment your dog brings to every daily tablet.

A 2024 study published in Frontiers in Veterinary Science (Wang et al., DOI: 10.3389/fvets.2024.1272711) confirmed that glucosamine supplementation itself alters gut microbiome composition in dogs. The gut is not a passive delivery tube for these ingredients - it actively interacts with them. A dog with a compromised or depleted microbiome may receive a genuinely inferior effective dose, regardless of what the label says.

Why Neither YuMOVE Nor Seraquin Solves the Real Problem: The Gut-Joint Axis

This is the conversation I have most often in clinic - and it is the one both YuMOVE and Seraquin leave owners completely unprepared for.

You can give your dog the finest glucosamine and chondroitin money can buy. But if the gut lining is compromised, the microbiome is depleted, or intestinal inflammation is active, you are pouring those ingredients into a system that cannot use them properly. Treating the joint without treating the gut is like pouring water into a leaky bucket. The joint is the outcome. The gut is the system that determines how much of any supplement actually reaches it.

I see this in clinic regularly. A dog has been on a reputable joint supplement for months with minimal improvement. The joints are structurally reasonable for the dog's age. But the gut health is not. There is a history of antibiotics - from ear infections, skin infections, UTIs - that has depleted the microbiome. There is intermittent soft stool. There is chronic low-level gut inflammation. Once we address that, the response to joint supplementation often improves noticeably.

Prebiotics, probiotics and postbiotics work together to maintain gut barrier integrity, support the microbial environment that these nutrients must pass through, and reduce intestinal inflammation that disrupts absorption. They are not a nice extra. They are arguably the foundation everything else rests on. Our guide to the dog gut-immune connection covers this in depth, and our article on postbiotics for dog gut health explains the newest and most compelling piece of this puzzle.

Neither Seraquin nor YuMOVE contains a single prebiotic, probiotic, or postbiotic ingredient. For any dog with a history of antibiotic use, gut sensitivity, dietary transitions, or chronic stress - which, in my experience, describes the majority of dogs presenting with joint concerns - this is a structural problem that no amount of glucosamine overdosing can compensate for.

Does Seraquin's Higher Glucosamine Dose Actually Mean It Works Better?

Seraquin's 1,000mg glucosamine across 2 daily tablets (for a 30kg dog) is higher on paper than the 600mg delivered by 2 scoops of Juno Daily. This deserves an honest explanation rather than a marketing deflection.

High glucosamine doses in tablet supplements exist partly to compensate for the absorption inefficiency of the tablet format itself. When a dose-normalised comparison study shows tablets deliver between 38% and 60% of the plasma concentration achieved by a liquid formulation (Maxwell et al., 2016), the logical commercial response is to put more active ingredient in the tablet and hope enough gets through.

A pure bioavailable powder does not require this same overcorrection. The physical format means the active ingredient is not embedded in a compressed matrix with magnesium stearate and dicalcium phosphate slowing dissolution. And when that powder is paired with a comprehensive pre-, pro- and postbiotic system, the intestinal environment is actively supported for better nutrient uptake - meaning more of what is in the formula actually reaches circulation at therapeutically useful concentrations.

This is why I do not look at raw milligram numbers in isolation. The number on the label is not what your dog absorbs. What your dog absorbs depends on formulation format, gut health, and the microbiome environment at the time of dosing.

Which UK Dog Breeds Does the Absorption Gap Affect Most?

The bioavailability question applies to all dogs, but it is more clinically significant in certain breeds - particularly those that are genetically predisposed to both joint problems and gut sensitivity.

Labrador Retrievers are the classic example. They carry significant risk of hip and elbow dysplasia and are also prone to dietary indiscretion, food sensitivities, and gut disruption. A Labrador on antibiotics for a recurrent ear infection - a common presentation in my clinic - may be a dog whose joint supplement is delivering far less than the label suggests, at exactly the time it is needed most.

Cocker Spaniels present a similar profile. High energy, gut-sensitive, and with a particular vulnerability to ear infections requiring antibiotics. Our dedicated guide on Cocker Spaniel joint care goes into more detail on breed-specific considerations.

French Bulldogs face an even more complex picture. Their compressed anatomy, tendency toward spinal issues and gut dysbiosis, and frequent antibiotic exposure through puppyhood mean that conventional joint supplementation alone may be genuinely insufficient. See our French Bulldog mobility guide for breed-specific guidance.

German Shepherds, Golden Retrievers and Rottweilers all carry well-documented joint predispositions - and all benefit significantly from a supplementation strategy that treats the gut and the joint as the connected system they actually are. Our guide to Golden Retriever hip support is worth reading if you own one of these breeds.

The Complete Alternative: Why I Recommend Juno Daily Over Both

Both YuMOVE and Seraquin are approaching the same problem from the joint outward - and stopping there. Juno Daily was formulated to treat both the gut and the joint together, because the science increasingly shows that gut health directly determines how much of any joint supplement your dog actually absorbs.

Per 2 scoops (the daily dose for a dog over 30kg), Juno Daily delivers: Glucosamine 600mg, Chondroitin 300mg, Omega-3 DHA 200mg, Prebiotics - Chicory Root 500mg and MOS 700mg, Probiotics - Calsporin Bacillus velenzensis 4 Billion CFUs, Postbiotics - Inactivated Lactobacillus helveticus and Lacticaseibacillus paracasei 30 Billion Cells, Spirulina 1,000mg, Slippery Elm 400mg, L-Carnitine 150mg, and Vitamin E 20mg.

No fillers. No binders. No maltodextrin. No magnesium stearate. No dicalcium phosphate. 100% active ingredient powder - meaning every milligram of every ingredient is doing something useful.

The dosing is straightforward: under 10kg takes half a scoop daily, 10-20kg takes 1 scoop, 20-30kg takes 1.5 scoops, and over 30kg takes 2 scoops.

The gut support system - prebiotics, probiotics and postbiotics working together - maintains the intestinal environment that joint nutrients must pass through. Slippery Elm soothes the gut lining. Spirulina provides a natural antioxidant and immune-support layer. L-Carnitine supports cellular energy metabolism. The formula treats the whole dog, not just one joint mechanism.

This is what I mean when I say the question of "YuMOVE vs Seraquin" is, in a sense, the wrong question. Both are joint products. Neither is a system. Our guide to whether all-in-one supplements are good for dogs gives a balanced breakdown of why a single comprehensive formula often outperforms stacking multiple single-function products.

YuMOVE vs Seraquin: Value for Money and What You Are Actually Paying For

Both Seraquin and YuMOVE are ongoing monthly costs that add up significantly over the years, particularly for larger breeds. Neither is cheap, and the cost-per-day for a large dog on a loading dose can be substantial.

Seraquin is widely available through vet practices and online pharmacies. YuMOVE is accessible via subscription directly from Lintbells/Vetnique as well as pet retailers, which brings the cost down. Both are genuine products and neither is a scam.

The question I ask my clients is this: if you are spending on a joint supplement every month for years, and a significant portion of the active ingredient never reaches the bloodstream because the gut environment is not optimised to receive it, how much of that spend is actually translating into clinical benefit for your dog? That is the calculation worth making.

Our piece on the best all-in-one dog supplements in the UK gives further context on what genuine value looks like in this category.

My Vet's Verdict: How YuMOVE, Seraquin and Juno Daily Rank

1. Juno Daily (vet-formulated all-in-one powder): Addresses both the gut and the joint in a single 100% active formula. The only product in this comparison that treats the absorption problem rather than ignoring it. No fillers, no binders, no wheat or soy or gluten. Made in the UK. The gut-joint axis is treated as the integrated system it actually is.

2. YuMOVE Joint Care PLUS: A solid, well-researched UK product with strong clinical evidence behind its ActivEase GLM extract. The addition of hyaluronic acid for joint lubrication gives it an ingredient advantage over Seraquin. Its limitations are the tablet format's effect on bioavailability, the presence of binding fillers, and the complete absence of any gut-microbiome support. The brand's acquisition by Vetnique and US manufacturing shift is worth noting for UK buyers.

3. Seraquin: Higher raw glucosamine and chondroitin doses than YuMOVE PLUS, and the turmeric inclusion is a genuine attempt at antioxidant-mediated cartilage protection. However, the bioavailability of standard turmeric extract at 50mg is genuinely limited without a phospholipid complex to enhance absorption - the research supporting curcumin in dogs has typically used phytosomal forms at higher doses. Seraquin is a respectable vet-clinic product, but it is a narrower formula than YuMOVE and leaves the same gut-absorption gap unaddressed.

If you are weighing other alternatives, our review of the best YuMOVE alternatives for UK dogs and our comparison of YuMOVE vs Nutraquin Plus cover additional products in the UK market.

Is YuMOVE or Seraquin Safe for Long-Term Daily Use?

Both Seraquin and YuMOVE are formulated for long-term daily use and have good safety profiles. Dogs with shellfish sensitivities should approach the GLM content in YuMOVE with care. Seraquin's turmeric content is at a level generally considered safe, though dogs with known sensitivities to turmeric or those on anticoagulants should be discussed with their vet first.

Any supplement - however well formulated - should be discussed with your vet before starting, particularly if your dog is on prescription medication or has a known digestive condition. If your dog is showing significant signs of joint pain or lameness, please seek a clinical examination rather than relying on supplementation alone.

Frequently Asked Questions

Is Seraquin stronger than YuMOVE?

On raw glucosamine and chondroitin doses, Seraquin delivers more per daily dose for a 30kg dog - 1,000mg glucosamine and 760mg chondroitin versus approximately 1,080mg glucosamine compounds in YuMOVE PLUS. However, YuMOVE includes Green-Lipped Mussel with a broader omega-3 anti-inflammatory profile, plus hyaluronic acid, which Seraquin lacks entirely. "Stronger" depends which mechanism you are measuring.

Can I give my dog Seraquin and YuMOVE together?

Combining them is unlikely to cause harm and would produce meaningful glucosamine and GLM overlap. The more important question is whether either product - or both together - is addressing the gut-absorption gap that limits how much your dog benefits from any joint supplement. Stacking two joint products without addressing gut health is a costly approach with uncertain returns.

Does Seraquin really work for dogs?

The ingredients in Seraquin - glucosamine HCl, chondroitin sulphate, and turmeric - each have scientific support for joint health. Many owners report positive results, and the product has a long track record in UK vet clinics. Like all tablet-format supplements, the effective dose absorbed is lower than the label suggests, which is particularly relevant for dogs with compromised gut health.

How long does YuMOVE take to work in dogs?

YuMOVE recommends a loading phase of doubling the daily dose for the first 4 to 6 weeks before assessing results. GLM-based products work gradually by supporting the body's own anti-inflammatory processes - they are not painkillers. Most owners notice meaningful changes by 6 to 8 weeks, consistent with the Royal Veterinary College study supporting the brand.

Which is better for an older dog with arthritis - Seraquin or YuMOVE?

For established arthritis in an older dog, YuMOVE PLUS or YuMOVE Max Strength is likely the better choice between these two, given the clinical evidence behind ActivEase GLM and the addition of hyaluronic acid for joint lubrication. That said, an older dog is also more likely to have a history of antibiotic use and gut compromise - making the gut-joint axis argument even more relevant.

Is turmeric in dog supplements actually effective?

Curcumin, the active compound in turmeric, has genuine anti-inflammatory properties and has shown promise in canine osteoarthritis studies - particularly when used as a phytosomal complex that enhances bioavailability. Standard turmeric extract, as used in Seraquin at 50mg per tablet, has much poorer oral absorption. The clinical benefit at this specific dose has not been independently established in peer-reviewed canine trials to my knowledge.

My dog has been on YuMOVE for months with no improvement - why?

This is one of the most common questions I get in clinic. When a dog shows minimal response to a well-formulated joint supplement, gut health is often the factor worth investigating. A depleted microbiome - from antibiotics, diet changes, stress, or chronic gut inflammation - significantly reduces absorption of glucosamine, chondroitin, and other active ingredients. Supporting the gut alongside the joint often produces improvements that months of joint supplementation alone did not achieve.

Does Seraquin need a vet prescription?

No. Seraquin is classified as a veterinary nutritional supplement in the UK, not a prescription medicine. It is widely available through vet practices, online veterinary pharmacies such as VioVet and Pet Drugs Online, and at Boots. No prescription is required, though speaking to your vet before starting any supplement for a dog with existing health conditions is always advisable.

Is Seraquin or YuMOVE better for a dog recovering from surgery?

Post-surgical dogs - particularly following cruciate ligament repair or joint procedures - often have depleted microbiomes from perioperative antibiotics. In that context, a supplement with gut support alongside joint ingredients is likely to deliver better effective absorption than either Seraquin or YuMOVE alone. Joint cartilage support from glucosamine and chondroitin remains relevant post-surgery, but the gut environment at that stage is frequently compromised in ways that limit how much reaches circulation.

Can puppies take YuMOVE or Seraquin?

YuMOVE has a specific young dog formula, and Seraquin can be used in younger dogs on a reduced dose. For large-breed puppies with genetic joint risk - Labradors, German Shepherds, Golden Retrievers - starting proactive joint support early is a conversation I have regularly with owners. The breed-specific gut sensitivity that often develops through puppyhood makes the gut-joint argument particularly relevant from a young age.

Does YuMOVE contain Green-Lipped Mussel and is that better than chondroitin in Seraquin?

Yes - YuMOVE's GLM powder is the primary source of chondroitin in its formula, alongside a range of Omega-3 fatty acids including ETA that have documented anti-inflammatory effects. Seraquin delivers chondroitin directly as sodium chondroitin sulphate at 380mg. The GLM approach offers broader anti-inflammatory coverage; the direct chondroitin approach offers higher measured doses. Neither is definitively superior - the clinical relevance depends on the individual dog's condition, gut health, and the bioavailability of both at the time of dosing.

What is the main difference between YuMOVE and Seraquin?

The clearest differences are: YuMOVE includes Green-Lipped Mussel (a source of Omega-3 fatty acids and chondroitin) and hyaluronic acid, which Seraquin lacks entirely. Seraquin delivers a higher direct glucosamine dose (500mg vs approximately 270mg) and includes turmeric extract for antioxidant support, which YuMOVE does not. Both are compressed tablets with binding fillers, and neither contains any gut support.
