Laminitis can develop rapidly, cause significant pain, and in severe cases lead to permanent damage to the hoof. Understanding the causes, recognising the early signs, and implementing the right management strategies are essential for every horse owner.
What is Laminitis?
Laminitis is an inflammation and weakening of the sensitive laminae within the hoof. These structures connect the hoof wall to the pedal bone and play a vital role in supporting the horse’s weight. When the laminae become damaged, the connection can weaken, leading to pain, lameness, and in severe cases, rotation or sinking of the pedal bone.
Common Causes of Laminitis
Several factors can contribute to laminitis, including:
- Excessive intake of rich grass, particularly during spring and autumn.
- Equine Metabolic Syndrome (EMS).
- Pituitary Pars Intermedia Dysfunction (PPID or Cushing’s disease).
- Obesity and insulin dysregulation.
- High-sugar or high-starch diets.
- Stress, illness, or severe infections.
- Excessive concussion on hard surfaces.
Many modern cases are linked to metabolic issues, particularly insulin resistance, making diet and weight management crucial.
Early Warning Signs
Recognising the signs early can significantly improve outcomes. Watch for:
- Reluctance to move or turn.
- A shortened or “pottery” gait.
- Increased digital pulse in the feet.
- Warm hooves. Shifting weight from foot to foot.
- Leaning back onto the hindquarters to relieve pressure on the front feet.
If you suspect laminitis, contact your veterinarian immediately.
Managing Laminitis
Successful management typically involves:
- Veterinary assessment and treatment.
- Restricting access to high-sugar grass.
- Feeding a low-sugar, low-starch diet.
- Weight management where appropriate.
- Corrective farriery and hoof care.
- Monitoring underlying metabolic conditions.
Alongside these measures, some supplements may provide valuable nutritional support.
Supplements That May Support Horses Prone to Laminitis
Magnesium
Magnesium plays a role in glucose metabolism and insulin function. Some horses with metabolic issues may benefit from magnesium supplementation, particularly when dietary intake is inadequate.
Biotin
Biotin is widely recognised for supporting healthy hoof growth and hoof horn quality. While it will not treat laminitis itself, it may help improve hoof integrity during recovery.
Zinc and Copper
These essential trace minerals contribute to hoof strength, skin health, and overall metabolic function. Many UK forage analyses show deficiencies or imbalances in these nutrients.
Herbal Support
Some supplements include herbs such as cinnamon, milk thistle, or fenugreek, which are often used to support metabolic health. However, scientific evidence varies, and owners should seek professional advice before relying on herbal products.
Choosing the Right Supplement
Not every horse prone to laminitis requires the same nutritional support. Factors such as forage quality, body condition, workload, and underlying health conditions should all be considered.
When selecting a supplement:
- Look for products from reputable manufacturers.
- Avoid supplements containing unnecessary sugars or molasses.
- Consider a forage analysis where possible.
- Discuss supplementation with your vet or an equine nutritionist.




Prevention is Better Than Cure
While supplements can play a supportive role, they should never replace good management. Careful grazing control, maintaining a healthy body condition, regular exercise where appropriate, and routine veterinary care remain the cornerstones of laminitis prevention.
By understanding the risks and providing targeted nutritional support, horse owners can help reduce the likelihood of laminitis and support long-term hoof health.
