We are exploring glucosamine today.

About a decade ago, glucosamine was marketed and sold as a joint supplement for horses. It is still available for joint support in dogs and humans, but seldom as a supplement for horses. 

In this episode, I discuss my experience with glucosamine, sharing its origin and clarifying some of the holistic principles it breaks.

Nutrients vs. Nutraceuticals

Nutrients are the vitamins, minerals, and essential fatty acids that are essential for life and must come from food. Glucosamine is a nutraceutical, a non-essential compound found naturally in cartilage that can help manage joint inflammation. It is not a dietary requirement, and it does not address deficiencies.

Doubt Around Glucosamine

Glucosamine was once widely used in equine joint supplements, often combined with MSM or chondroitin. However, many horse owners and practitioners saw no real benefits. Its popularity was due to marketing and general concerns about joint health and mobility in horses.

Inflammation 

Supplements alone cannot cure joint inflammation. Often, underlying factors (stress, poor diet, and excessive sugar) play a role. If those issues go unaddressed, even the best supplements will be inneffective.

Insulin-Resistant Horses

Glucosamine is an amino sugar that contains a glucose molecule, which raises red flags for insulin-resistant horses or those with a sluggish, congested liver. Those horses are already prone to inflammation and joint pain, and adding glucosamine may further burden their liver’s ability to metabolize.

Long-Term Supplementation

Long-term use of glucosamine without addressing nutrient deficiencies may do more harm than good. The liver metabolizes everything that enters the body, so long-term supplementation could overburden it, especially if the supplement is unnecessary or of low quality.

Source Matters

Most glucosamine gets sourced from shellfish, which violates holistic principles for horses, as they are strict herbivores. Using animal-based ingredients for horses is not considered species-appropriate and should always be avoided unless the supplement is truly effective.

Glucosamine Forms and Sulfur Sensitivity

Glucosamine comes in different forms- either glucosamine sulfate or glucosamine HCl. As the sulfate version can cause sensitivities, like hives or respiratory issues, glucosamine HCl may be a safer option for horses with sulfur sensitivity.

Evaluating Supplement Effectiveness

To assess whether a supplement is truly helping, always consider whether mobility is improving and inflammation is decreasing. If you cannot see or measure any benefit, reconsider its use. Addressing nutrient deficiencies will likely lead to more effective and lasting results.

Study Limitations 

Scientific studies on glucosamine are inconclusive and often based on other species (like rats, mice, or humans), so they may not reflect the realities of insulin-resistant or metabolically compromised horses. Ultimately, the individual history and response of the horse should guide your decisions.

Final Considerations

Although glucosamine is not inherently harmful, its long-term use should be questioned, especially for horses with insulin resistance. Glucosamine is not an essential nutrient, and it may place unnecessary strain on the body. 

Always prioritize foundational nutrition before turning to nutraceuticals.

Today, we cover three foods to avoid for better horse health. This topic ties into our last discussion, where we explored toxicity in horses and how accumulated toxins can build up over time and lead to serious health issues.

Sources of Toxicity in Horses

Horses get exposed to various sources of toxicity, mainly through chemicals and preservatives in their food and water, medications, vaccinations, and deworming agents. Over time, the toxins build up and can overwhelm the immune system, leading to chronic health issues like inflammation, allergies, and sensitivities. Addressing the diet and removing toxic elements is often the first step toward recovery when horses are unwell.

Corn

Corn has high-calorie content and energy density, making it a common ingredient in horse feed. However, corn lowers digestive pH, leading to leaky gut and immune issues. It is also high in starch, which can overwhelm the small intestine if fed in excess, as the undigested starch can reach the hindgut, where it ferments, potentially causing acidosis, colic, or laminitis. Its low fiber content and imbalance of protein and amino acids make it less suitable as a standalone feed. There is also a risk of mold contamination when corn is improperly stored. While corn can be an energy boost for horses with high caloric needs, it is best to use it sparingly.

Wheat Middlings

Wheat middlings, a byproduct of milling wheat for flour, are often used as a source of fiber and protein in horse feed. They can be high in phosphorus and low in calcium, creating an imbalance that can affect bone health in horses if consumed in excess. Wheat middlings can also ferment in the hindgut, leading to digestive upsets like colic or laminitis. High levels of non-structural carbohydrates in wheat middlings can also be problematic for horses prone to metabolic issues like insulin resistance or equine metabolic syndrome. While middlings can be part of a balanced diet, feed them in moderation and combine them with other sources of fiber and essential nutrients.

Processed Oils

Canola, soybean, corn, or hydrogenated oils are not ideal for horses as they undergo high-temperature processing that generates free radicals, harming the immune system and leading to various diseases. Soybean oil can also create hormonal imbalances due to its phytoestrogen content. It is essential to choose cold-pressed, high-quality oils and only add them to the diet when necessary.

High-Fat Diets

High-fat diets can provide energy for horses doing heavy work or needing to gain weight, as fats are calorie-dense and provide slow-burning energy without the risks associated with high-starch feeds. However, horses lack a gallbladder and are biologically unsuited to process large quantities of oils. So, high-fat diets can cause digestive issues, malnutrition, and liver strain, slowing gut motility and worsening conditions like colic or ulcers.

Balancing Nutrition

While some challenging cases, like underweight or elderly horses, may require short-term use of problematic foods or oils, the goal should always be to provide high-quality, minimally processed nutrition in the long term. Horses thrive on a natural diet that aligns with their biology. For optimum health and resilience in your horse, pay attention to sensitivities and make adjustments where necessary.

Final Thoughts

Avoid ingredients like corn, wheat middlings, and processed oils. Focus on natural, high-quality feeds, and tailor the feeding strategy to fit the specific dietary requirements of your horse and support its long-term health and vitality.

I am excited to welcome Jessica Fobert as my guest today!

Over the past decade, Jessica and I have worked together on many challenging cases, and I have come to value her input as a trusted second opinion for my clients. She is a hoof care practitioner and lifelong horse lover, registered with both the Canadian Equine Hoof Care Association and Progressive Hoof Care Practitioners. She and her business partner, Natalie, run a rehab facility in Toddham, Ontario, where they take on the toughest of cases. 

Join us as Jessica dives into the critical work she does at the rehab, debunking common trimming myths and highlighting the crucial importance of proper hoof care.

Many Cases Go Undiagnosed

Owners and professionals alike should be vigilant and proactive, as subclinical laminitis often goes unnoticed. Many horses can have inflammation without full-blown laminitic episodes, and even minor hoof distortion, recurring abscesses, or poor posture may be early signs. 

Inflammation 

Hoof inflammation starts before any rotation or visible damage occurs. It typically results from systemic stress, poor nutrition, or mechanical imbalance. While X-rays may not reveal early changes, heat, soreness, gait alterations, or behavioral changes can indicate trouble brewing inside the foot.

Movement and Circulation 

Stabling a sore horse may seem protective, but confinement reduces circulation and delays healing. Movement is crucial to restoring hoof health. Gentle, controlled exercise within the comfort zone of the horse, often with the help of boots, can significantly improve blood flow and tissue regeneration.

Boots

Boots help reduce inflammation and promote healing, allowing sore horses to move more comfortably. However, they are not a permanent solution. 

Avoid Over-trimming 

Trimming should preserve the sole and reduce leverage without forcing the foot into an artificial shape. Over-trimming or removing too much sole worsens instability.

Be Cautious with Certain Treatments

Corrosive thrush treatments may kill bacteria but can also damage live tissue, making reinfection more likely. Non-corrosive antimicrobials can restore microbial balance without damaging sensitive tissue, soothing the foot, and helping to reset its microbial environment. Consistency and gentle application are the key.

Gut Health 

Thrush and white line disease can recur when gut health is compromised. High-sugar, high-starch diets fuel inflammation and weaken hoof tissue from the inside. Horses fed low-NSC diets will often show rapid hoof improvement. In some cases, long-standing issues like contracted heels and white line disease will resolve completely within months of a diet change.

Lasting Change

Lasting hoof changes must be supported from the inside, as no trim can undo the effects of a poor diet. Contracted heels, long toes, and weak hoof structures are often diet-driven. Even horses that have been trimmed carefully for years may not improve until their processed feeds get replaced with low-sugar alternatives. 

The Power of Movement

Movement is essential for healing hooves. Even sore horses should be allowed to move freely within their comfort range. Boots can encourage movement, reducing pain and enabling gradual increases in circulation and use. 

Metal Shoes

Metal shoes may provide instant relief for some horses. However, they increase concussion and vibration, which can worsen laminitic damage over time. Whenever possible, barefoot is ideal, but there are situations where temporary shoeing provides a helpful bridge.

Euthanasia Is a Complex Decision

For owners facing the possibility of euthanasia due to chronic laminitis, the most important factors to consider are quality of life, age, and the extent of internal damage. A younger horse with good overall health and minor pathology may fully recover with time, while an older horse with extensive remodeling and no progress after months of care may not. It is not about how long you have been trying. It is about whether or not progress is still possible.

There Is Hope with the Right Support

Horses can recover from severe laminitis. Even cases that seem hopeless can recover with the right support. A strong rehab plan includes proper trimming, pain relief, an appropriate diet, and enough movement. If the damage is not too severe and the blood supply remains intact, healing can be dramatic.

Owner Education Makes a Difference

Owners who understand hoof anatomy, inflammation, and the impact of diet are better prepared to advocate for their horses. A good support team includes trimmers, veterinarians, and professionals who collaborate and communicate openly.
