This week, we are continuing with the theme of toxicity because it lies at the root of most health issues horses experience.

Looking back at past cases, the pattern is unmistakable. Once you remove those dietary toxins, things start to turn around. The tricky part is knowing what is helpful and what is harmful, so that is what we are focusing on today.

Over-Supplemented

Over-supplementation becomes a major contributor to malabsorption, inflammation, and chronic health problems. Many ingredients, especially synthetic, inflammatory, or poorly absorbed ones, cause toxicity, overwhelm digestion, and suppress the immune system.

Interpreting Ingredient Lists

Horse owners must learn to interpret ingredient lists to distinguish food ingredients from vitamins, minerals, preservatives, flavorings, and fillers. Many supplements contain a few beneficial components surrounded by ingredients that negate their benefits. So it is essential to know which are organic, which are inorganic, and which are highly processed.

Detoxifying Means Removing, Not Adding

Detoxification comes from removing substances rather than adding more. Every ingredient requires a digestive resource, and when the system is congested, even beneficial nutrients turn toxic. Removing non-essential supplements frees the liver, gut, and cells to function normally, improves absorption, and reduces inflammation. A temporary reset with hay, water, and salt will allow the digestive system to heal.

The Fear of Stopping Supplements

Many owners fear that their horses will regress if they remove their supplements, yet many horses decline because they cannot properly absorb the supplements they get. Most commercial ingredients are so processed and inorganic that the body barely recognizes them. Simplifying is not deprivation. It restores capacity. Nutrition from forage and whole foods becomes far more effective with reduced digestive stress.

Why Simplifying Works

Turnarounds can happen when owners strip everything back to only a few essential nutrients plus detoxifying herbs. Even horses on high-quality programs with good ingredients can improve dramatically by reducing their overall load. Fewer ingredients reduce competition for receptors, lowering inflammation and improving the absorption of fat-soluble nutrients and minerals.

Ingredient Competition

Inflammatory ingredients block the absorption of critical minerals, fat-soluble vitamins, and proteins. Even high-quality formulas can fail if too many ingredients compete for absorption. Less is often more because simplified diets reduce receptor blockage, increase bioavailability, and allow the body to use what it gets.

Choosing Supplements

Labels market conditions like ulcers, metabolic syndrome, and digestion, without guaranteeing ingredient suitability. Horses with ulcers, for example, cannot absorb synthetic nutrients well, especially while on proton pump inhibitors. So owners must evaluate what each ingredient actually does rather than trusting marketing claims.

A Three-Step Supplement Audit

1. Count every ingredient your horse consumes daily across all supplements.
2. Categorize each item (food, vitamin, mineral, preservative, flavoring, or colorant)
3. Assess processing level and quality

Auditing provides clarity and helps you decide what to remove, what to keep, and what genuinely benefits the horse.

Do you know what exactly is in your horse's supplements, and what they're actually doing for their health?

Keeping your horse's diet and supplement program clean is one of the most beneficial things you can do for them. There is nothing that turns a horse's health around faster than cleaning up their diet and supporting their health from the inside out.

Much of what we read online about horse health is misleading. So, for those of you following a more natural and holistic path by focusing on the diet, lifestyle, and environment of your horses before turning to drugs or surgery, having the correct understanding is essential. I hope that each episode helps you view conditions like insulin resistance, equine metabolic syndrome, and laminitis with clearer eyes and more confidence.

Today, we are exploring insulin, what happens when it stays high for too long, why it becomes toxic in the body, and how this links to metabolic dysfunction, chronic inflammation, and the early stages of laminitis.

Insulin Can Become Toxic

When insulin remains elevated for too long, it starts to act like a toxin. It constricts blood vessels, increases inflammation, damages cells, and impairs nutrient delivery, especially to their highly sensitive hooves.

Inflammation and Insulin Feed Each Other

High insulin drives inflammation. Inflammation drives insulin levels even higher, damaging tissues, reducing circulation, and increasing the likelihood of laminitis. Breaking this cycle requires addressing both inflammation and insulin simultaneously.

The Role of Nutrition and Detox

Supporting your horse with proper nutrition and removing toxins is essential. Antioxidants, clean feed, and reducing chemical exposures will help the body repair damaged cells, restore balance, and bring insulin levels back into a healthy range.

Hoof Health Depends on Circulation

Hoof care and internal health must go hand in hand. Restricted blood flow in the hooves worsens laminitis and founder. Proper trimming, padding, booting, and movement are all critical, along with dietary and metabolic support.

The Whole Body Matters

If symptoms are visible in the feet, the rest of the body will be affected as well. Supporting liver function, reducing stressors, and regenerating cells throughout the body improves overall health and helps prevent further complications.

Masterclass

Last week, we explored the early signs of toxicity in horses. Today, we revisit a previous episode to clarify what toxicity is and how it affects your horse.

Toxicity is one of the leading causes of equine disease. When the toxic load of horses exceeds what they can process, it becomes hard for their tissues to remain healthy, their organs to function as they should, and their body systems to work together to sustain good health.

Today, I scratch the surface of the vast and complex topic of toxicity, giving you a little food for thought. Since this is a massive subject, I will likely revisit it and dive deeper into some of the points we cover today in future episodes.

Understanding Toxicity in Horses

Toxicity refers to the degree to which a substance can harm cells, tissues, organs, or entire systems. For horses, toxicity often accumulates gradually, influencing their health over time. Genetic makeup, nutrition, and environmental exposure are all factors that determine how well a horse can handle toxins. Well-nourished horses with good constitutions and minimal exposure to harmful substances are generally more resilient. Yet they can also struggle as they age, particularly between 14 and 16 years, when signs of imbalance often emerge.

Early Signs of Toxicity

The initial effects of toxicity can be subtle and easy to overlook. A horse may develop a dull coat, cracked hooves, or irregular shedding patterns. Some subtler changes, such as stiffness, swelling, joint discomfort, a weakened immune system, or slow recovery from illness, could also indicate that the body struggles to handle its toxic load.

Key Sources of Toxicity

• Environmental chemicals in feed, hay, and water
• Fertilizers, preservatives, and additives
• Pathogens, like bacteria, viruses, and parasites

Dietary imbalances

Dietary imbalances are another major factor contributing to poor equine health. Excess sugar or protein can stress the body and lead to inflammation, metabolic issues, and poor gut health, and a diet heavy in oils can disrupt the gut microbiome.

Acidity

Acidity in the body often results from an imbalanced diet, leading to conditions like leaky gut, systemic inflammation, and joint issues. Hormonal imbalances, such as prolonged high cortisol or insulin levels, also cause significant damage over time, contributing to tissue breakdown, laminitis, and immune dysfunction.

Antioxidants

Antioxidants are crucial for combating free radicals, the unstable molecules that damage cells and DNA. Free radicals naturally occur during metabolic processes, but increase with high toxic loads. Without sufficient antioxidants to neutralize them, free radicals can accelerate aging, weaken the immune system, and cause long-term damage.

The Cumulative Effect of Toxicity

Even though toxins seldom cause immediate harm, they accumulate over time. A horse that has consumed feed with additives, dealt with multiple infections, or been on long-term medications may eventually show signs of toxicity. The cumulative effect often leads to nutritional deficiencies, compromised immunity, and declining health.

Strategies for Reducing Toxicity

• Eliminate unnecessary supplements and observe how the horse responds to a more natural diet.
• Prioritize high-quality feeds and hay with minimal additives, and avoid excessive sugar, protein, or oils, as they can disrupt metabolic health and the gut microbiome in horses.
• Address pathogens and infections promptly.
• Support detoxification with bioavailable nutrients to restore reserves and help the body manage its toxic load effectively.

Final Thoughts

Toxicity develops slowly. Understanding
