Don’t Be Hoodwinked: The Cheapest Supplement In Your Feed Room Might Be Outperforming Your Expensive One
Cold weather changes how horses drink, how their gut moves, and how their bodies hold onto water, and electrolytes are the switchboard that keeps all of those systems running.
In winter, many horses simply don’t drink enough. Cold water dulls thirst, slows gut motility, and reduces the natural urge to rehydrate. Even when a horse isn’t sweating, he’s still losing electrolytes through urine and normal metabolism, and those losses quietly add up. Without enough sodium, the thirst mechanism can’t fire properly, the gut can’t stay hydrated, and the risk of impaction rises long before you see dry manure or a dull coat. (Don't forget - colic is the leading cause of death for horses under 20).
Winter dehydration is subtle, silent, and far more common than owners realise, which is why a small, consistent supply of electrolytes, or even just salt, is one of the simplest ways to protect gut health in cold weather.
Electrolytes are simply charged minerals that keep a horse’s cells, nerves, muscles, and hydration systems working. The main ones are sodium, potassium, chloride, magnesium, and calcium. They control everything from thirst to gut motility to muscle contraction. But of all the electrolytes, sodium is the boss. It’s the one the body uses to regulate fluid balance, blood volume, and the movement of water in and out of cells.
When a horse doesn’t get enough sodium, the body has to keep electrical balance somehow. So it does something owners never hear about:
It robs potassium from the tissues to compensate.
This is the body’s emergency workaround to keep cells firing, but it comes at a cost. Potassium is supposed to stay inside cells, especially muscle cells. When the body starts pulling it out to make up for low sodium, you see muscle fatigue, poor recovery, weakness, and changes in hydration long before you realise the diet is unbalanced.
When you draw bloods, the horse looks low in potassium, but that’s not actually the problem.
That’s why the solution isn’t fancy electrolyte mixes, it’s salt. Sodium chloride fixes the imbalance at the source. When sodium intake is adequate, the body stops stealing potassium, the thirst mechanism switches back on, and hydration stabilises naturally.
Electrolyte mixes can be useful in emergencies, in extreme hot weather or unusually heavy work, but they don’t replace the foundational, daily need for sodium. Without salt, nothing else works properly.
Why Himalayan salt is a good option in winter
Free choice Himalayan salt blocks work well because horses actually want to use it. Its natural mineral profile gives it a mild flavour horses prefer over plain table salt, so they lick more consistently and maintain better sodium intake without you having to force the issue. It’s also naturally low‑moisture and slow to dissolve, which means it holds up in wet paddocks and frosty weather far better than loose salt.
Loose Himalayan salt is a better option to include in the feed bin because you can monitor the amount they are receiving to make sure minimums are met.
While Himalayan Salt does include trace minerals, they aren’t present in high enough amounts to act as a complete supplement, and that’s fine. We offer Trace Minerals in other forms. (See below).
What About Other Salt Blocks?
A Himalayan salt lick is simply a clean, hard source of salt, and that’s what makes it better than licks that are bound with molasses or cattle blocks that contain added sulfur.
When you bind a lick with molasses, you turn it into a sweetened feed block, not a true salt source. Horses then consume it for the flavour rather than for physiological need, which leads to unpredictable and often excessive intake. The added sugar also makes these blocks unsuitable for horses with insulin resistance or PPID, and the softer texture means horses can bite off chunks rather than regulate their salt intake through licking.
Sulfur‑containing blocks have a different problem: they’re generally formulated for cattle (ruminants - a completely different digestive system), not horses. They’re softer, they crumble, and they often contain additives horses don’t need or shouldn’t have.
A Himalayan block avoids all of this. It is extremely hard, weather‑stable, and unflavoured, so horses lick it only when they need sodium. It doesn’t melt, ferment, or attract insects, and it doesn’t encourage chewing. Because it contains salt and trace minerals only, intake is more predictable and nutritionally suitable for horses.
Price Comparison
Excluding "premium" formulas that will often include amino acids, and vitamins, the market average for salt/potassium electrolyte supplements for horses is around $25 - $30/kg.
Horses get almost all of their potassium from forage - grass, hay, and chaff. It is the most abundant mineral in plants, and horses eating normal roughage easily exceed their daily potassium requirement without needing supplementation.
That leaves salt. The most cost-effective approach to purchase our Himalayan Salt is a 5kg pouch which is $5.40/kg. We also offer it for $11 for 1kg, and $6.30/kg for a 3kg pouch.
We recommend a minimum of 30g of loose Himalayan salt in the feed every day, plus a free‑choice Himalayan block available in the paddock or stable. The loose salt ensures the horse actually consumes the sodium his body needs to regulate hydration, nerve function, and mineral balance. The block supports natural self‑regulation - horses lick more on days when their sodium requirement rises and less when it doesn’t. This combination keeps the thirst mechanism switched on, stabilises electrolyte balance, and prevents the subtle winter dehydration that causes so many avoidable problems.
Other Trace Minerals
Alongside salt, we offer supplements that cover the minerals horses genuinely struggle to obtain in correct ratios from forage alone: magnesium, calcium, copper, zinc, iodine, and selenium. These aren’t random additions - they’re the core minerals that determine hoof quality, coat health, immune resilience, metabolic stability, and overall comfort.
Each product is formulated to deliver these nutrients in biologically appropriate amounts, without the guesswork or imbalance that comes from mixing and matching generic feeds.
When salt provides the foundation and these minerals fill the gaps, the whole system works the way the horse’s biology intended.
