If you've searched for this trend and landed on our earlier piece about the "horse gelatin" recipe, you're not in the wrong place by much — but you're looking at a different trick. This one doesn't involve gelatin at all. It's a mineral salt, usually described as a rare "blue" salt, dissolved with a pinch of baking soda in warm water. Video titles routinely bolt the word "horse" onto this recipe too, alongside "blue salt trick" and "baking soda trick," which is exactly why the two trends are so easy to confuse. We treated them as separate claims and checked this one on its own terms.
The Short Version
The salt at the center of this recipe is a real thing — a naturally blue-tinted rock salt mined mostly in Iran, colored by a mineral called sylvinite rather than any dye. Combined with baking soda, another real and ordinary kitchen ingredient, it makes a mineral-and-electrolyte drink that isn't dangerous in a single normal serving for most healthy adults. What isn't supported is the much bigger promise attached to it in most of the videos using the word "horse" or "blue salt trick" — a fast, dramatic fix for a private, often-marketed concern that has nothing to do with hydration or minerals. We found no clinical evidence behind that part of the claim, and several independent scam-tracking sites have already flagged the marketing pattern around it directly.
What the recipe actually calls for
Set aside the branding and the recipe is simple: a small amount of Persian blue salt, sometimes labeled "blue rock salt" or "Persian blue salt," dissolved in warm water along with a pinch of ordinary baking soda (sodium bicarbonate). Some versions add lemon juice. There's no cooking step, no rare botanical, and nothing that requires special sourcing beyond the salt itself, which is sold as a gourmet finishing salt independent of any of these videos.
The salt's blue color is real and has a mineralogical explanation: it comes from sylvinite, a potassium-bearing mineral naturally present in certain rock-salt deposits, most commonly cited to Iran's Semnan region. Alongside sodium chloride, this salt does genuinely contain measurable potassium, magnesium, and calcium — the same class of minerals found in any electrolyte supplement. That much is not the fictional part of the story.
Where the "horse" name actually comes from
We looked for a specific product, company, or ingredient that would explain why "horse" gets attached to this recipe, the same way we checked for an actual horse-derived ingredient in the gelatin trend. We found the same pattern here: no retail product, no ingredient, and no company using "horse" as anything other than a recycled hook. A large number of videos simply stack all three labels — "horse trick," "blue salt trick," and "baking soda trick" — into the same title and description, which is almost certainly why searches for one now surface the others. The overlap looks like shared marketing shorthand between at least two originally separate recipes, not evidence that either one involves an actual horse or a horse-derived ingredient.
The claims that go further than minerals
An electrolyte drink is a modest, plausible thing. That is not where most of this recipe's marketing stops. A large share of the videos and near-identical articles built around "the salt trick" and "the horse trick" frame the recipe as a fast fix for a specific, sensitive concern many men search for a shortcut on — described in the marketing as something a warm glass of salted water can resolve in as little as fifteen seconds. We could not find a single published clinical trial testing this recipe, this salt, or this specific combination for that claim, or for the broader mechanism some sellers point to as the explanation. Real research on how minerals and hydration affect the body exists in general, but nothing we found connects it to the specific, dramatic promise attached to this recipe.
This is also where the recipe has visibly turned into a product category rather than staying a free kitchen trick. Multiple pre-dosed capsule and gummy products have launched using nearly identical "salt trick" and "blue salt" branding and near-identical sales pages, under a rotating set of different brand names rather than one identifiable company. Independent scam-tracking coverage has already reviewed several of these by name and concluded the marketing relies on dramatic before/after storytelling rather than disclosed clinical testing.[1] We are not linking to or naming any specific one of these products here — the pattern is the finding, not any single brand.
What the real evidence says about the ingredients themselves
Baking soda is a genuine, FDA-recognized over-the-counter antacid ingredient with a real, narrow, well-documented use: temporarily neutralizing stomach acid.[2] Outside that specific use, medical sources are consistent that regular or excessive intake carries real risk — gastrointestinal discomfort at moderate doses, and at higher or repeated doses, a genuine risk of metabolic alkalosis and electrolyte disturbance. Sources reviewing this specifically flag extra caution for anyone with high blood pressure, kidney disease, or heart failure, since the added sodium load can worsen fluid retention and cardiovascular strain, and note it is not recommended as a regular antacid for children under 12 or for use beyond about two weeks without medical guidance.[3] None of that is unique to this trend — it's the same caution that applies to baking soda generally — but it's worth knowing before treating a "trick" recipe as something to repeat daily.
The blue salt itself is lower-risk in the small quantities the recipe calls for; it's still salt, and it does not have any FDA-recognized health claim attached to it beyond what any dietary mineral source would carry. Its real electrolyte content is genuine. What it does not have is any evidence tying it to the specific, dramatic promise most of the "horse"/"blue salt" marketing is actually selling.
The bottom line
"Horse soda" isn't a distinct ingredient or a single product — it's a label that's been stacked onto a mineral-salt-and-baking-soda recipe that's really a separate trend from the gelatin trick that already carries the same "horse" branding on this site. The salt is a real, naturally colored mineral product; the baking soda is a real, narrowly useful antacid ingredient; and mixing a small amount of either in water isn't dangerous on its own. The much bigger promise attached to the recipe in most of the videos using this name is not something we could verify through any credible source, and it's the same promise several independent scam-tracking outlets have already flagged in the wave of copycat capsule products the trend has spawned. If you're curious about the recipe, it's worth trying — if at all — for what it actually is: a mineral drink, not the dramatic fix the marketing around it is selling.
