Arthritis in Horses – What You Need to Know
15th Dec 2025
Noticed your horse moving stiffly after a workout, or hesitating before that jump they used to sail over? It's worth looking into before it becomes a bigger issue. Arthritis affects over 60% of horses with lameness issues, and catching it early makes all the difference between a comfortable retirement and years of chronic pain.
Here's what matters most: arthritis in horses can't be cured, but it can be managed brilliantly with the right approach. But are supplements like 4CYTE good for horses? Let’s explore how it plays a proven role in arthritis management.
Key Takeaways
- Arthritis is progressive joint inflammation causing cartilage breakdown, most common in hocks, fetlocks, knees and pasterns.
- Early signs include subtle stiffness that improves with movement, reluctance to move, and reduced range of motion.
- The active ingredient, Epiitalis, is scientifically proven to stimulate healthy cartilage production and reduce inflammation, making 4CYTE good for arthritis.
- Management combines veterinary care, appropriate exercise, and targeted joint support to maintain your horse's quality of life.
What is Arthritis in Horses?
Arthritis is inflammation within the joint that damages the protective cartilage cushioning your horse's bones. Think of the cartilage as shock absorbers. Once they wear down, the bones can rub against each other, making movement painful.
There are three main types you'll encounter:
- Osteoarthritis (the most common) develops gradually from normal wear and tear. Performance horses, older horses, and those with poor conformation (improper physical structure) are most at risk. It's progressive and accounts for the majority of arthritis diagnoses.
- Traumatic arthritis follows an acute injury, either from a bad landing, a kick, or repetitive stress. Young athletic horses can develop this surprisingly early in their careers.
- Septic arthritis occurs when infection enters the joint, often through a wound. This is an emergency requiring immediate veterinary attention.
The joints that take on the hardest workload – hocks, fetlocks, knees and pasterns – are most vulnerable. These structures endure massive forces every time your horse moves, jumps or performs.

Spotting the Early Warning Signs
Watch for:
- Stiffness that eases with movement. They start off tense but loosen up as they warm up.
- Hesitation before jumping, reluctance to work, shortened stride, or unwillingness to move forward.
- Subtle lameness, which is especially noticeable after flexion tests or on hard ground.
- Swelling or heat around joints (more obvious in acute cases).
- Difficulty after lying down, particularly in older arthritic horses who may struggle to stand.
Performance horses might simply feel "not quite right" before obvious lameness appears. Trust your gut – if something's off, get it looked at. Early intervention is crucial in slowing the progression of arthritis and preventing further joint damage.
Is 4CYTE Good for Arthritis?
Yes, 4CYTE is good for arthritis in horses, and there's solid science backing it up.
The 4CYTE horse supplement contains Epiitalis® – a patented active ingredient and plant seed oil extract from Biota orientalis (also known as the Chinese 'healing tree'). It stimulates healthy cartilage production, slows breakdown, and suppresses anti-inflammatory properties that cause poor joint function and pain.
4CYTE is good for horses for multiple reasons, but particularly for:
- Horses with diagnosed osteoarthritis showing stiffness or reduced performance
- Post-surgical recovery (many vets recommend it after arthroscopy)
- Prevention in performance horses before problems start
- Older horses needing ongoing joint support
Several studies have demonstrated the benefits of 4CYTE in managing osteoarthritis, reducing inflammation, and improving mobility – with visible improvements evident within one week.
Australian equine veterinarians regularly recommend 4CYTE because it works in conjunction with other treatments, such as NSAIDs, joint injections, or physiotherapy. Unlike long-term NSAID use (which can cause gastric ulcers), 4CYTE is safe for daily, ongoing use.
It's essential that when you’re combining treatments, you consult a professional veterinarian.
Supporting Your Horse's Joint Health
Is 4CYTE good for arthritis as a standalone treatment? It's powerful, but works best as part of a comprehensive approach:
- Exercise matters. Contrary to what you'd think, arthritic horses need regular, moderate movement to keep joints mobile and prevent stiffening.
- Weight control is non-negotiable. Every extra kilogram puts added stress on already compromised joints. Keep your horse at a healthy body condition score.
- Quality footing reduces shock. Use arena surfaces that provide cushioning without being too deep.
- Regular hoof care (every 4-6 weeks) ensures balanced weight distribution across joints.
Combining these management strategies with targeted supplement support from vet-approved products gives your horse the best shot at staying comfortable and sound.

Working with Your Vet
An arthritis diagnosis requires professional expertise. Your vet will perform lameness exams, flexion tests, potentially nerve blocks and imaging to pinpoint the problem. They'll create a tailored treatment plan that might include joint injections, medications, and rehabilitation protocols.
Don't wait for obvious lameness. If something feels off, book a vet visit immediately. Early intervention prevents irreversible damage, ensuring your horse is healthy, comfortable, and able to perform longer.
