What Glucosamine Actually Does Inside Your Horse's Joints

Glucosamine is a naturally occurring amino sugar found in the connective tissue of all mammals — including horses. It is a nutritional compound, not a pharmaceutical drug. Horse owners who are uncertain whether this sits in the supplement or medication category can be reassured: glucosamine is a building block your horse's body already produces and uses. What changes with age and workload is how much the body makes on its own.

The Joint Health Crisis Horses Face as They Age and Train

Precision Equine Solutions addresses a very specific biological problem: equine joints face enormous mechanical stress every day. Training, competition, and even routine movement grind cartilage surfaces against each other under substantial load. A young horse compensates by synthesising generous amounts of glucosamine internally — but that synthesis declines steadily with age.

Think of a joint that is running dry. When glucosamine supply falls, cartilage thins because the raw material for repair is absent. Synovial fluid — the lubricant that cushions every stride — loses viscosity. The joint loses its natural shock-absorption capacity, and every footfall transfers more impact to subchondral bone and surrounding connective tissue.

Horses can begin showing measurable joint degradation as early as their mid-teens. Working horses — those competing, breeding or doing regular ridden work — face an accelerated timeline because load accumulates faster than the body can offset it. This is not a scare story. It is the biological context that makes supplementation a rational, proactive choice rather than a desperate reaction.

How Glucosamine Supports Cartilage, Synovial Fluid and Connective Tissue

Our approach at Precision Equine Solutions centres on one mechanism: glucosamine is a precursor to glycosaminoglycans. Glycosaminoglycans are the structural components that build and maintain both articular cartilage and synovial fluid. When you supplement glucosamine at therapeutic doses, you give the body the raw material to synthesise and repair these structures.

Three functional roles matter most. First, glucosamine stimulates chondrocytes — the cells that maintain cartilage — to produce more proteoglycans, the key structural proteins in healthy cartilage matrix. Second, it contributes to the viscosity of synovial fluid, helping restore the lubricating quality that reduces friction between joint surfaces. Third, glucosamine shows mild anti-inflammatory properties that may reduce joint inflammation without the systemic side effects associated with long-term NSAID use.

Glucosamine Sulfate vs Glucosamine HCl — What the Difference Means

Glucosamine sulfate is the form with the largest body of research across mammals. The sulfate group itself may provide additional joint-support benefits, and most veterinary studies reference this form. Glucosamine HCl contains a higher concentration of pure glucosamine per gram but carries less research specifically in horses.

The PJS formula uses Glucosamine HCl, delivering dense therapeutic amounts per serving. Both forms are used in equine supplements. Glucosamine is derived naturally — typically from crustacean shells or fermented corn — making it a compound your horse's body already recognises.

What the Science Really Says: Veterinary Research on Equine Glucosamine

The evidence base for equine glucosamine is smaller than for human or canine use — and that is a legitimate point to acknowledge rather than dismiss. Owners who ask hard questions deserve honest answers.

What the research does support is meaningful. In vitro studies on equine cartilage cells confirm glucosamine stimulates proteoglycan synthesis — the mechanism is real at the cellular level. Pharmacokinetic studies confirm that orally administered glucosamine reaches equine joints, though absorption rates vary by form and dose.

In Vitro Cellular Evidence

Laboratory studies on equine cartilage cells show glucosamine directly stimulates proteoglycan synthesis — the biological mechanism is confirmed at the chondrocyte level.

Pharmacokinetic Confirmation

Studies confirm oral glucosamine reaches equine joints at detectable concentrations. Loading doses of 10,000–20,000 mg/day are required to achieve meaningful plasma levels in a 500 kg horse.

Veterinary Consensus

Many equine veterinarians consider mechanistic evidence and cross-species data sufficient to justify glucosamine use. Large-scale equine RCTs are limited, but the evidence base is growing steadily.

Which Horses Benefit Most from Glucosamine — Conditions, Life Stages and Timelines

Understanding the mechanism is one thing. Knowing whether your horse fits the profile for meaningful benefit is another. Not every horse responds identically. Life stage, underlying condition and accurate expectations all determine the outcome.

Joint Conditions Where Glucosamine Shows the Most Promise

Precision Equine Solutions formulated PJS to serve horses across a wide range of joint and connective tissue challenges. Here are the conditions where glucosamine for horses shows the strongest rationale for use — along with honest guidance on what to expect from each.

  • Osteoarthritis

    The most widely supported use. Glucosamine addresses the degenerative process itself — stimulating cartilage repair and restoring synovial fluid quality — rather than simply masking pain. This is where the evidence is strongest and the mechanistic case most compelling. Long-term supplementation is appropriate because the condition is progressive.

  • Navicular Disease

    Glucosamine may support the digital cushion and navicular bursa connective tissue, which are structurally relevant to navicular syndrome. This is a supportive role alongside veterinary management — not a cure. Horses with diagnosed navicular disease benefit from glucosamine as part of a multi-modal management plan.

  • Ringbone

    Periarticular new bone growth in the coffin or pastern joint. Glucosamine may slow cartilage degradation at these joint surfaces, helping maintain comfort as the condition progresses. Results are typically most visible in horses supplemented early in the disease course.

  • Sidebone

    Ossification of the lateral cartilages of the foot. Glucosamine's role here is preventative and supportive rather than reversing established ossification. Early supplementation in horses showing predisposing conformation is a rational preventative step.

  • Kissing Spine

    Impingement of the dorsal spinous processes involves both bony and synovial joint components. Glucosamine addresses the synovial joint component and may reduce inflammation at the facet joints of the spine. Note that kissing spine has multiple contributors — glucosamine is one element of a comprehensive management plan, not a standalone treatment.

  • OCD / Osteochondrosis

    A developmental joint condition in young horses where cartilage-to-bone conversion is disrupted. Glucosamine may support cartilage matrix integrity during growth phases. Use in young horses with confirmed OCD should always be guided by a veterinarian.

  • Laminitis Recovery

    Glucosamine supports joint integrity in horses whose movement is compromised by chronic laminitis. Important caveat: glucosamine does not address lamellar tissue damage, which is the primary laminitis lesion. Its role is supporting the associated joint mechanics in horses with altered loading patterns.

  • Tendon Injuries

    Glucosamine contributes glycosaminoglycan precursors relevant to tendon matrix, which shares structural similarities with cartilage. Useful as part of post-injury recovery protocols, particularly where the tendon-bone interface is involved.

  • Post-Surgical Recovery

    Glucosamine is increasingly included in post-operative joint care protocols. The rationale is straightforward: surgery places significant demand on cartilage repair processes, and supplying the raw materials for that repair is mechanistically sound.

Horses often present with multiple concurrent conditions — this is common in older sport horses. Glucosamine is generally compatible with most management plans, but always confirm with your vet before supplementing a complex case, particularly if other medications are already in use.

Glucosamine Across Life Stages: Senior Horses, Young Horses, Broodmares and Elite Competitors

We work with horses at every stage of life. The rationale for glucosamine shifts depending on what the horse is facing — but the underlying biology connects them all.

Senior Horses (15+ Years)

Natural glucosamine synthesis declines significantly. Visible stiffness after rest, shortened stride, and reluctance to trot or turn tightly are common indicators supplementation should begin — or continue if already started. Expect a loading phase before visible change.

Young Horses and Foals

Used preventatively, particularly in breeds with high OCD incidence. Evidence for foal supplementation is limited — veterinary guidance is recommended before starting in horses under two years. In young sport horses entering work, glucosamine supports cartilage integrity during the physical stress of early training.

Broodmares

Pregnancy weight gain places significant load on all four joints. Current evidence does not show harm from glucosamine during gestation, but always consult your vet before supplementing a pregnant mare. Post-foaling, broodmares returning to work benefit from glucosamine to support joint recovery from months of elevated loading.

Competition Horses

Glucosamine is permitted under FEI rules (see Section 5 for full competition compliance details). Start loading four to eight weeks before competition season, then maintain throughout. Frame glucosamine as a performance longevity tool — it keeps joints healthy through a season rather than acting as an acute performance enhancer.

Owners should consider starting glucosamine before visible symptoms appear, especially in performance horses over eight years old. Prevention costs less — in every sense — than recovery.

How Long Before You See Results — and Signs It Is Working

The PJS loading phase works on a defined timeline. Set your expectations accurately: glucosamine is not an analgesic. It does not produce immediate pain relief the way an NSAID does. What it does is rebuild the biological environment inside the joint.

Weeks 2–4

Synovial fluid changes begin at the cellular level. Not yet visible externally.

Weeks 4–8

Owner-observable mobility shifts: more willing to move forward, less stiffness after rest.

Weeks 8–12

Full loading phase complete. Structural effects on cartilage and synovial fluid established.

Month 3+

Maintenance efficacy established. Step down to maintenance dose and maintain consistently.

If your horse is not responding, the most common reasons are straightforward: under-dosing (check the product provides 10,000 mg or more per day during loading), stopping before the loading phase completes, or using a product where labelled glucosamine content is not verified. Horses with severe, irreversible joint damage may show limited response regardless of dose — this is biological reality, not product failure.

How to Choose the Right Glucosamine Supplement — Formulation, Ingredients and Quality Signals

The glucosamine supplement market is overwhelming. Dozens of products make similar claims at wildly different price points. This section gives you three sequential tools to evaluate any product independently — format, ingredient combinations, and label quality — so you can make a decision based on evidence rather than marketing.

Glucosamine Forms: Powder, Pellet, Liquid and Paste — Which Works Best?

Our PJS All-In-One Leg Solution is available in formats designed to suit horses of different temperaments and management routines. Here is how the formats compare across the market.

  • Powder

    Most cost-effective, highest dose-per-gram flexibility. Palatability varies — fussy horses may refuse it in dry feed. Dampening into chaff or a small amount of soaked hay cube usually resolves resistance. Best for owners feeding the same ration twice daily.

  • Pellets

    More palatable for most horses. Pre-measured servings reduce under-dosing risk. Slightly higher cost per dose than bulk powder but the improved acceptance rate often makes the difference between a horse getting their full dose and a horse leaving it in the bucket.

  • Liquid

    Fastest theoretical absorption rate. Easy to mix into wet feed. Requires refrigeration after opening and has a shorter shelf life. Effective for horses with dental issues who struggle with solid formats.

  • Paste

    Used primarily for short-term loading or travel. Not ideal for long-term daily use — the cost per dose is significantly higher than other formats and compliance over weeks becomes impractical.

  • Treats

    Highest palatability. Ideal for fussy horses or horses where concealing the supplement is difficult. Check glucosamine concentration per treat carefully — many treat formats require multiple units to reach a therapeutic daily dose.

What About Human Glucosamine Supplements?

Human glucosamine products are formulated for a 1,500 mg daily dose — appropriate for a 70 kg person. A therapeutic equine loading dose requires 10,000–20,000 mg per day. Scaling human products to equine doses makes them impractical and often more expensive per effective dose than a purpose-formulated equine supplement.

SUPPLEMENT FORMATS Powder Pellets Liquid Paste Treats Choose based on your horse's palatability and your daily management routine

Combination Ingredients That Multiply Results: Chondroitin, MSM, Hyaluronic Acid, Collagen and More

The PJS All-In-One Leg Solution includes the proven combination ingredients that work synergistically with glucosamine. Here is why each one matters — and how they interact at the joint level.

Chondroitin Sulfate

Inhibits enzymes that break down cartilage while glucosamine stimulates repair — these two work by complementary mechanisms. The glucosamine-chondroitin combination is the most widely studied pairing across species and is considered the baseline standard for quality joint support.

MSM (Methylsulfonylmethane)

Provides bioavailable sulphur, a structural component of connective tissue. MSM also has well-documented anti-inflammatory properties that complement glucosamine's structural role. Together they address both structure and inflammation more completely than either alone.

Hyaluronic Acid

A glycosaminoglycan itself. Oral HA has demonstrated bioavailability in horses and contributes directly to synovial fluid viscosity — the lubricating quality that reduces friction between joint surfaces. Particularly valuable for horses with diagnosed synovitis.

Hydrolysed Type II Collagen

Provides the structural framework for cartilage matrix. Hydrolysed type II collagen may also stimulate the immune system to produce more cartilage-protective compounds — a mechanism distinct from and complementary to glucosamine's direct precursor role.

Turmeric (Curcumin)

An anti-inflammatory herb that may reduce joint inflammation. Absorption requires a carrier fat or piperine. Important note: turmeric appears on some competition restricted substance lists — verify with your governing body before use in competing horses.

Omega-3 Fatty Acids

Systemic anti-inflammatory effect. DHA and EPA from marine sources are the most bioavailable forms. Linseed/flaxseed provides ALA, which horses convert to EPA/DHA less efficiently. Best used as a complement to — not replacement for — the glucosamine-chondroitin-MSM core.

The Evidence-Backed Triple Combination

Glucosamine + Chondroitin + MSM is the most evidence-supported combination for equine joint health. This is the starting point for any quality supplement evaluation. Additional ingredients — hyaluronic acid, collagen, omega-3s — build on this foundation but do not replace it.

How to Read a Supplement Label and Spot Under-Dosed or Low-Quality Products

The label is where marketing and reality diverge. Six checkpoints tell you everything you need to know about whether a product is worth your money.

Equine Supplement Facts — Sample Panel
Serving Size: 60g (2 scoops)
Glucosamine HCl 1 10,000 mg 2
Chondroitin Sulfate 2,500 mg
MSM 5,000 mg
Hyaluronic Acid 50 mg
Inactive Ingredients 5
Natural flavours, rice bran
NASC Certified 4 3rd Party Tested 6
  • 1 Form declared — HCl or sulfate, not just "glucosamine"
  • 2 Milligrams per serving — 10,000 mg minimum for loading
  • 3 No proprietary blend — each ingredient listed separately
  • 4 NASC seal — independent manufacturing audit
  • 5 Inactive ingredients — no artificial colours or high-sugar carriers
  • 6 Third-party testing claim — verifiable by CoA on request

Use these six checkpoints on every product you evaluate — including PJS.

  • Glucosamine form declared. The label must state glucosamine sulfate or glucosamine HCl. "Glucosamine" without qualification is a red flag. You cannot verify potency or bioavailability without knowing the form.
  • Milligrams per serving. A therapeutic loading dose for a 500 kg horse is 10,000–20,000 mg per day. If a single serving delivers 1,000–2,000 mg, the product is under-dosed. This is the most common cause of supplement failure.
  • No proprietary blend. Proprietary blends list a combined weight without disclosing individual ingredient amounts — making it impossible to verify whether any single ingredient is present at a therapeutic dose. Avoid this labelling practice for core joint ingredients.
  • NASC certification. The National Animal Supplement Council Quality Seal confirms independent auditing of manufacturing practice and label accuracy. Not mandatory, but a meaningful trust signal.
  • Inactive ingredients check. Avoid artificial colours and high-sugar carriers — particularly relevant for metabolic horses. Fillers that exceed 30% of total serving weight dilute the active content significantly.
  • Third-party testing claim. Look for language referencing independent assay or certificate of analysis availability. This confirms the manufacturer will put label claims to external verification.

Dosage, Safety and Feeding Your Horse Glucosamine Every Day

Two failure modes end more supplementation plans than anything else: under-dosing to save money, and skipping the loading phase because results feel slow. This section covers how to get both right — plus honest guidance on safety for metabolic horses and practical day-to-day administration tips.

Getting the Dose Right: Loading Phase, Maintenance and Adjusting for Your Horse's Weight

Our protocol requires a loading phase because glucosamine must accumulate in joint tissue to a therapeutic concentration before structural effects begin. This is not a marketing concept — it is a pharmacokinetic reality confirmed in equine bioavailability studies.

Light horse / Pony (<400 kg)
6,000–10,000 mg loading
Average horse (400–550 kg)
10,000–15,000 mg loading
Heavy horse / Warmblood (550 kg+)
15,000–20,000 mg loading

Load for four to eight weeks at the higher dose — or up to twelve weeks for horses with diagnosed arthritis before stepping down to a maintenance dose of 5,000–10,000 mg per day. Choosing a product with a smaller serving size to save money nearly always means under-dosing, which is the single most common reason owners report no benefit from glucosamine supplementation.

Glucosamine has a wide safety margin in horses. There are no documented cases of acute toxicity from standard loading doses. The only documented side effect at very high doses is occasional loose stools, which resolves when the dose is reduced.

Is Glucosamine Safe for Horses with EMS, Cushing's Disease or Metabolic Conditions?

This is one of the most important questions for a large and growing group of horse owners — and it deserves a real answer rather than a reflexive "ask your vet."

The concern about glucosamine and metabolic horses originates from the structural relationship between glucosamine and glucose. Early theoretical concerns suggested glucosamine might contribute to insulin resistance. Current equine research does not support that concern at therapeutic doses.

Key Guidance for Metabolic Horses

  • Studies in horses with equine metabolic syndrome (EMS) have not found clinically significant increases in blood glucose or insulin levels from glucosamine supplementation at therapeutic doses.
  • The real metabolic risk in many equine supplements is the carrier or base — molasses-heavy products that deliver significant sugar alongside the joint ingredients.
  • For horses with Cushing's disease (PPID), the glucosamine molecule itself is not contraindicated — but review the full product formulation for sugar and starch content.
  • For horses with active laminitis episodes, discuss any dietary change including supplementation with your vet before starting.
  • Always consult your veterinarian before supplementing a horse with a diagnosed metabolic condition. This is non-negotiable regardless of what the research shows at a population level — your horse's individual case matters.

The practical takeaway: scrutinise the carrier ingredients as carefully as the active ingredients. A low-sugar, clearly labelled product with verified glucosamine content is the appropriate choice for metabolic horses — not blanket avoidance of glucosamine itself.

Practical Feeding Tips: Fussy Horses, Timing, Mixing and Storage

The PJS All-In-One Leg Solution is designed for daily use. These practical guidelines ensure your horse gets the full therapeutic benefit — not half a dose left at the bottom of a bucket.

  • Mix into a small carrier first. Add powder or liquid to a small amount of chaff or dampened feed before adding to the full ration. This prevents the horse from sorting through and leaving the supplement behind.
  • Consistency over timing. Glucosamine can be given at any time of day. Choose a feeding that happens reliably every day without exception. Missed days interrupt the accumulation of plasma concentration.
  • Build up for fussy horses. Start at one-quarter of the full dose and build up over one to two weeks. Most resistance is palatability-driven and resolves with gradual introduction.
  • Switch format before giving up. If a horse rejects powder consistently, try pellets or paste before concluding the horse will not accept supplementation. Format acceptance is individual and unpredictable.
  • Store correctly. Sealed container, away from direct sunlight, cool and dry location. Humidity accelerates degradation in both powder and pellet formats. In hot or humid climates, buy in smaller quantities more frequently rather than bulk-storing.
  • Daily consistency is everything. It is the single biggest determinant of whether a horse achieves and maintains therapeutic plasma concentration. One missed day a week is equivalent to a 14% dose reduction over the loading period.

How Glucosamine Compares — Alternatives, Vet Opinions and Competition Rules

This is the impartial comparison resource owners search for when weighing glucosamine against everything else available — injectable treatments, other oral supplements and complementary therapies. Where glucosamine has limitations, this section says so. Where it excels, it explains why.

Glucosamine vs Other Joint Supplements and Treatments

Each comparison uses the same structure: what the alternative does, how it differs from glucosamine, and the recommended approach.

  • MSM

    Anti-inflammatory and structural support via bioavailable sulphur. MSM works best alongside glucosamine rather than instead of it. The combination addresses both structure and inflammation more completely than either alone — this is why quality equine joint supplements include both. Not a substitute for glucosamine's glycosaminoglycan precursor role.

  • Chondroitin Sulfate

    The closest partner to glucosamine in the supplement world. Inhibits cartilage-degrading enzymes while glucosamine stimulates repair — these two mechanisms are complementary, not overlapping. The glucosamine-chondroitin combination is more effective than either individually per the available cross-species research. This is a combination ingredient, not an alternative.

  • Hyaluronic Acid

    Directly improves synovial fluid quality and viscosity. Oral HA has demonstrated equine bioavailability. Glucosamine primarily supports cartilage structure while HA addresses joint fluid quality — they target different aspects of the same problem and work well together. Particularly valuable for horses with confirmed synovitis.

  • Devil's Claw

    A herbal anti-inflammatory — harpagoside is the active compound. Effective for pain reduction. However, Devil's Claw is a restricted substance under FEI rules and many national governing bodies.

    It is not a structural joint support compound and does not provide the glycosaminoglycan precursor benefits glucosamine delivers. Use with caution in competing horses.
  • Green-Lipped Mussel

    Provides glycosaminoglycans, omega-3s and chondroitin naturally. Research in horses is limited compared to dogs. Constituent ingredients are proven effective — but dosing precision is difficult compared to isolated glucosamine.

    A useful natural source to consider as part of a broader nutritional plan. Not a direct substitute for therapeutic-dose glucosamine.
  • Joint Injections

    Corticosteroid or HA intra-articular injections produce faster, more potent anti-inflammatory results than oral supplements. However, repeated corticosteroid injections carry documented risks of cartilage degradation over time. Oral glucosamine is best positioned as the long-term structural companion to — not replacement for — injection protocols.

    Cost: a course of equine joint injections typically costs several hundred dollars per joint per treatment. Long-term oral supplementation represents substantially lower ongoing cost for preventative maintenance.

What Vets Say and How Glucosamine Fits Into a Broader Joint Care Plan

Veterinary opinion on glucosamine is not uniform — and honesty about this serves horse owners better than false consensus. Some vets are enthusiastic proponents. Others remain skeptical due to limited large-scale equine RCT data. A growing number take a pragmatic position: glucosamine is safe, not expensive relative to alternatives, and mechanistically credible enough to recommend as one component of a broader joint management plan.

Glucosamine is most effective when combined with appropriate exercise management — avoiding concussive surfaces, maintaining consistent low-impact work to preserve synovial fluid circulation — along with physiotherapy and cold therapy post-exercise, and targeted nutritional support.

For owners who have been told their vet "doesn't believe in supplements": the conversation is often more productive when framed around the specific mechanism — glycosaminoglycan precursor supply — and the horse's specific diagnosis rather than "should I give supplements generally." A mechanism-first conversation changes the dynamic.

Glucosamine PJS Formula Veterinary Treatment Exercise Management Physio & Cold Therapy Nutrition & Diet Surface & Load Mgmt

Always have a vet assess a horse showing lameness before starting supplementation. Glucosamine does not replace a diagnosis — it supports a horse whose diagnosis has been established. When vets do recommend specific equine joint products, the differentiating factors between leading brands and lesser-known alternatives are typically glucosamine concentration per serving, ingredient form, and manufacturing transparency — not brand prestige alone. Our equine joint supplement meets the highest standards on all three.

"The mechanistic case for glucosamine in equine joint health is sound. Glycosaminoglycan precursor supply declines with age and training load — replenishing it orally at therapeutic doses is a rational response to a real biological deficit. The quality of the product matters more than the concept itself: dose, form, and formulation transparency are the variables that determine clinical relevance." Consensus position — equine veterinary community on therapeutic glucosamine use

Competition and Racing: Is Glucosamine Permitted Under FEI and Other Governing Bodies?

The direct answer: glucosamine is not currently a prohibited substance under FEI rules. As a naturally occurring compound, it is not subject to withdrawal period requirements in most equestrian disciplines. Competing horses can remain on glucosamine supplementation through competition season without triggering a rule violation.

Three important nuances apply.

  • FEI

    PermittedFEI — Fédération Equestre Internationale

    Glucosamine is not listed on the FEI Equine Prohibited Substances Database. However, verify that every other ingredient in your chosen product is also compliant — combination products containing Devil's Claw or certain herbal anti-inflammatories are restricted under FEI rules even if glucosamine itself is not.

  • RACING

    Verify FirstRacing Jurisdictions (BHA, Racing Australia, USEF)

    Racing rules vary by jurisdiction. The British Horseracing Authority, Racing Australia and the USEF each maintain their own detection thresholds and permitted substance lists. Always check the current list from the relevant authority before competing under racing regulations — rules are updated periodically.

  • !

    Important"Competition Safe" Labels Are Not Regulatory Certifications

    Any product claiming to be "competition safe" is making a marketing assertion — not a regulatory certification. Always verify against the governing body's own published prohibited substances list rather than relying on the manufacturer's self-declaration. The FEI's Equine Prohibited Substances Database is the authoritative reference for international competition horses.

Find the Right Glucosamine Solution for Your Horse

You have done the research. You understand what glucosamine actually does inside a joint — how it supports cartilage through chondrocyte stimulation, restores synovial fluid viscosity, and provides the structural building blocks a working horse's body needs more of than it can make alone. What comes next is simpler: choosing a product built to the standards this guide has described, from a team that genuinely understands equine joint health.

Precision Equine Solutions built PJS All-In-One Leg Solution because the supplement market offered horse owners an uncomfortable choice between products that were under-dosed and products that were opaque about what was inside them. Our owners — owners who watched horses go from barely walking to playing in the pasture — deserve a product that does what the label says, at the dose that actually works.

My 26-year-old boy could barely walk — his stifle and hip on his left hind kept getting worse. I started Precision around eight months ago and he has significantly improved. He can go out and enjoy the pasture with his friends again, even through a cold winter. Giving him PJS has definitely given me more time with him.

Deborah G. — 26-year-old gelding with stifle and hip deterioration

My mare has struggled with hock arthritis since she was young. On PJS she moves much more freely and shows less discomfort at the trot and canter. I now use it for my younger horse as a preventative too. I highly recommend it.

Alison K.R. — mare with diagnosed hock arthritis

My horse was lame front left — grade 1, clean x-rays, no diagnosis, three months off work. The only change I made was adding PJS to his feed. One month later we were back to light work. Two weeks after that, we were competing again.

Melissa N. — Cowboy Mounted Shooting competition horse

I have taken my horse off PJS a few times thinking he was doing better with his locking stifle. Within a week each time, he was much worse. I have sworn never again will he go without it. It truly works.
