Diversity Before Numbers
Understanding What Your Horse Is Already Getting Before Adding More
When horse owners think about equine nutrition, the conversation often turns quickly to minerals. Calcium, magnesium, copper, zinc, selenium, ratios, percentages, and daily requirements can easily become the focus.
Those numbers can be useful. But before asking what needs to be added, I believe there is a much more important question: What is the horse already getting?
Your Horse Is Not Starting at Zero
A horse does not begin the day nutritionally empty and wait for us to fill in the numbers with supplements. Hay, pasture, browse, and other forage are food, and they should make up the majority of the horse's diet.
Forage provides far more than fiber. It supplies energy, protein, calcium, phosphorus, magnesium, potassium, iron, manganese, copper, zinc, and many other nutrients. Fresh plants also contribute vitamins, fatty acids, antioxidants, pigments, phytonutrients, and countless other naturally occurring plant compounds. Long before anything is added to the feed pan, nutrition is already entering the horse through food.
Look at the Numbers in Context
For an approximately 1,000-pound mature horse at maintenance, commonly used reference amounts place calcium at roughly 20 grams per day and phosphorus at around 14 grams per day. Now consider an ordinary forage example. Timothy hay containing approximately 0.48% calcium and 0.23% phosphorus could provide roughly the following at around 20 pounds of hay:
CalciumPhosphorus
Approximate daily reference~20 g~14 g
Illustrative 20 lb timothy hay intake~44 g~21 g
That does not mean every bale of timothy hay contains those exact amounts. Hay varies with soil, plant maturity, harvest, climate, storage, and many other factors, but that variability is part of the point. The horse is not beginning at zero.
Forage may already provide a substantial portion, or sometimes more than a commonly referenced amount, of certain nutrients before supplementation is ever considered.
Pasture Is Doing Nutritional Work Too
Pasture is not simply something that keeps a horse's stomach full. Growing grasses naturally contain minerals, protein, vitamins, fatty acids, antioxidants, pigments, and other plant compounds.
Those concentrations change with plant species, soil, rainfall, maturity, season, and growing conditions. A horse grazing pasture, eating hay, and browsing available vegetation therefore lives within a much broader nutritional environment than a requirement chart alone can show.
This is why forage has to remain the starting point. It is the horse's primary food source and should be doing most of the nutritional heavy lifting.
A Reference Number Is Not a Diagnosis
A nutritional reference amount gives us context. It does not automatically tell us that an individual horse is deficient simply because a calculated intake appears somewhat below that number.
True nutrient deficiencies absolutely occur. Severe deficiencies become much more likely when horses are genuinely underfed, receive poor or severely restricted nutrition for prolonged periods, have unusually high physiological demands, or live where a particular nutrient is especially limited.
But there is an important difference between saying, “This horse may be receiving less than a reference amount,” and saying, “This horse has a clinical deficiency.” Those are not the same thing.
Deficiency Is Only Half of the Conversation
We spend a great deal of time talking about what horses might be lacking. We spend far less time asking whether they may already be receiving more than they need.
More is not automatically better simply because something is essential. Nutrients interact with one another, and the balance of the entire diet matters.
Calcium and phosphorus are one familiar example. Their relationship matters just as much as looking at either number alone.
Trace minerals interact too. Continually adding concentrated sources without considering what is already being supplied can alter those relationships rather than improve them.
Toxicity Is Possible Too
Some nutrients have a much narrower margin between enough and too much than others. Selenium is one of the clearest examples.
Horses require selenium, yet excessive selenium can cause serious toxicity. Soil and forage concentrations can also vary considerably from one geographical area to another. That does not mean selenium should never be supplemented. It also does not mean every horse automatically needs supplemental selenium. It means there should be a reason for adding it.
The Horse Gets the Total
This may be one of the most important concepts in this entire conversation. A horse may be receiving good hay and pasture along with several different feeds, foods, and supplements.
Perhaps there is a mineral product, a hoof supplement, a gut supplement, a ration balancer, an omega product, seeds, herbal products, or fortified treats. Every one of those things may look perfectly reasonable when viewed by itself. But the horse's body does not read the labels separately. It receives the total.
Zinc from one source adds to zinc from another. Copper adds to copper, selenium adds to selenium, protein adds to protein, fats add to fats, and vitamins add to vitamins. All of that is then added to what hay, pasture, browse, and other foods were already providing.
This Is Why Stacking Matters
Stacking products does not automatically mean a horse is being harmed. It does, however, make it much harder to understand what the horse is actually receiving.
A hoof supplement may contain zinc, copper, methionine, biotin, and selenium. A mineral product may contain some of those same nutrients, while a ration balancer supplies them again. Another product may add yet another layer. Meanwhile, the forage never stopped contributing. At some point, the question needs to change from “What else can I give this horse?” to “Why does this horse need another thing?”
So Why Are Core Essentials So Important?
Core Essentials have a completely different job. They are not designed to replace forage, and they are not concentrated mineral supplements. They are also not intended to supply 100% of a predetermined list of mineral requirements from a scoop. Their purpose is botanical and nutritional diversity.
In a more natural environment, horses encounter grasses, leaves, flowers, stems, seeds, seasonal vegetation, and browse. Each plant brings a different nutritional and phytochemical profile. That is some of the biological diversity I am trying to restore through the Core Essentials line.
Herbs Are Food
An herb does not stop being nutritious because it also has medicinal properties. The whole plant carries nutritional, medicinal, energetic, and phytochemical characteristics at the same time.
For example; nettle still contains minerals, protein, fiber, chlorophyll, and other plant compounds. Amla still contributes vitamin C, polyphenols, and other phytonutrients, while rose hips bring another nutritional profile entirely.
Calendula, cleavers, peppermint, red clover, olive leaf, lemon balm, fenugreek, and every other botanical contribute their own nutritional chemistry to the finished formulation. The horse consumes the whole plant, so the nutritional contribution comes with it.
The Formula Came Before the Numbers
I did not create Equine Core Essentials by beginning with a nutrient chart and deciding how many milligrams of calcium, magnesium, potassium, or zinc I wanted the formula to contain. I began with the botanicals. I considered their nutritional properties, medicinal actions, energetics, phytochemistry, relationships, and how they belonged together within the complete master formulation.
Only after the formulation was established did I begin calculating its estimated nutritional contribution and that is where something very interesting became visible: the nutrition was already there. The nutritional analysis came after the formulation—not before it and I am beginning to show these numbers because I want horse owners to see what whole plants have been contributing all along. I am not showing them to create another set of numbers to chase.
Core Essentials Do Not Need to Replace Forage
When we compare the estimated nutritional contribution of Equine Core Essentials with conventional mineral reference amounts, Core supplies relatively small percentages of those larger mineral needs. I am completely comfortable with that because that is not its job.
Hay, pasture, browsing, self-selecting, and the rest of the horse's diet are supposed to provide the large nutritional foundation. Core Essentials adds another layer of whole plants carrying naturally occurring minerals, vitamins, protein, fiber, antioxidants, phytonutrients, and other biological compounds.
Other whole foods can broaden that nutritional landscape further. Camelina meal, for example, contributes protein, fiber, healthy fats, omega-3 fatty acids, and additional nutrients and also small amounts of rotating fruits, vegetables, roots, leaves, and other appropriate whole foods add something different again. The goal is not enormous quantities of any single food. The goal is nutritional diversity.
This Is Not Anti-Mineral
Mineral supplementation absolutely has a place. Some horses have increased requirements, some forage is genuinely low in particular nutrients, and geography can create legitimate nutritional gaps. Life stage, workload, health circumstances, or meaningful diagnostic findings may also give us a clear reason to provide additional support.
That is very different from automatically adding concentrated nutrients simply because a chart contains a number. When there is a reason to investigate further, forage analysis, blood work, veterinary diagnostics, or other appropriate targeted testing can have a purpose.
​
Testing Should Answer a Question
Testing can be valuable when there is a meaningful reason to investigate further. But not every test tells us what we think it does. I do not use hair mineral analysis to determine a horse’s nutritional mineral status or to balance a diet. Research in horses has found that mineral concentrations in mane hair do not reliably reflect mineral intake or tissue mineral status, and identical samples can even receive substantially different interpretations from different laboratories.
Blood work has a very different and important place. It can help identify disease, reveal meaningful abnormalities, and measure certain nutrients when the appropriate test is selected. But blood work also has limitations. Many minerals are tightly regulated in circulation, so a normal blood concentration does not necessarily mean dietary intake is ideal, while an abnormal result does not automatically tell us why it is abnormal.
A laboratory result is therefore one piece of the horse’s larger biological picture. History, forage and diet, physical presentation, environment, clinical findings, and the individual horse still matter. Testing should help answer a question—not create numbers for us to chase.
Additional support should have a reason to be there.
Before adding more, I like to know what's already there. I do not believe good nutrition is created by making every number on a spreadsheet line up perfectly. The horse lives in a constantly changing biological environment.
Pasture changes with season and weather. Hay changes from cutting to cutting, while the horse's workload, digestion, age, physiological demand, and overall condition change too.
So I begin with the foundation: forage, pasture and browse whenever available, clean water, salt, whole-plant botanical diversity, healthy whole-food fats, diverse whole foods, movement, environment, nervous system health, and observation of the individual horse, then I ask whether there is a reason to add something else.
Sometimes a horse truly needs more, sometimes something really is missing, and sometimes something is being supplied in excess, and sometimes we have simply become so accustomed to adding products that we never stopped to understand what was already there.
Before adding more, understand what the horse is already receiving. Diversity Before Numbers. Biology Before Supplementation.
