RespiraFix | Comprehensive Respiratory Support
Formulated for the airways that work hardest.
RespiraFix was formulated for one job, and it doesn't moonlight: supporting healthy respiratory function in horses whose lives ask a lot of their lungs - the stabled months, older barns, indoor schools, hay-fed winters and dry, dusty summers. Thirteen botanicals - peppermint, maritime pine, aloe vera, chamomile, garlic, liquorice root, coltsfoot, rosemary, thyme, marshmallow, rosehip, Curcuma longa and withania - prepared as concentrated extracts with added vitamin C, in the most comprehensive respiratory formula we make.

What is RespiraFix?
Comprehensive Respiratory Support
Our respiratory range is two products with one philosophy and very different builds. Breathe is the everyday one: five whole herbs, cut like a loose-leaf tea, for the ordinary stabled life. RespiraFix is this one: fourteen ingredients — thirteen botanicals prepared as concentrated extracts, plus vitamin C — the longest botanical list in the Hi Form range, in a powdered formula. Both do the same honest job: supporting healthy respiratory function in horses stabled for long periods or kept in dusty environments. The difference isn't the promise — it's how much formula turns up in the scoop. Most horses start on Breathe and stay there; RespiraFix is the step up for those needing more focused support, and the free nutrition advice team will tell you straight which half of the pair fits yours.
What we formulated it for
Let's say it as plainly as we're allowed: RespiraFix was formulated in Australia for the respiratory system, full stop — for the horse who spends long months stabled, works in an indoor school, eats hay all winter, or lives on a yard where dust is simply part of the weather. Not an all-rounder that mentions airways in passing; a formula with one purpose, built comprehensive because that purpose deserved it. If you're reading this page, chances are we don't need to describe your horse to you. Tell our free nutrition advice team the whole story — the horse, the yard, the vet's involvement if there is one — and they'll tell you honestly, one-to-one, whether RespiraFix belongs in the plan.
Thirteen botanicals, prepared the concentrated way
There's a reason RespiraFix is a powder while Breathe is tea-cut: thirteen botanicals don't fit in a 20g scoop as whole herbs. So every botanical here goes in as a concentrated extract — most at 6:1 or 10:1, and the aloe vera at a remarkable 200:1, two hundred kilos of plant into every finished kilo. Alongside them sits vitamin C, an antioxidant the formula carries two ways — added in its own right, and naturally through rosehip. And as with everything we make, the formula works as a whole: no hero ingredient, no supporting cast. Every ingredient is human grade and listed with Australia's TGA for human use, blended in our HACCP-certified, Feedsafe-accredited facility in Australia — no fillers, no artificial flavours, no preservatives, to the standard we've held since 1990.
What it does
Tap any benefit for the detail.
A horse moves an extraordinary volume of air through its day, at rest and in work. RespiraFix adds a daily layer of botanical nutrition supporting healthy respiratory function — fed with the ordinary ration, alongside the management that does the heavy lifting.
Thirteen botanicals — from peppermint, thyme and rosemary to maritime pine, withania and Curcuma longa — plus vitamin C, selected to complement one another and fed as a whole. No headline act, no supporting cast: the formula is the blend.
Concentrated up to 200:1
Muscles do the moving; joints just allow it. The formula supports muscle condition and topline in horses in work — one reason we've never made a joints-only product.
The one non-botanical in the tub is an antioxidant the formula takes seriously: added vitamin C on top of what the rosehip brings of its own accord. Antioxidant nutrition, done the herbivore-appropriate way.
Hay, straw, bedding and arena surfaces all travel with dust, and some set-ups carry more of it than others. RespiraFix was designed for horses stabled for long periods and those living or working around dust — feed it through the months your horse spends indoors, or year-round where the environment calls for it.
RespiraFix is deliberately the fuller, more concentrated of our two respiratory formulas. If you're weighing it against Breathe — or wondering whether your horse needs either — the free nutrition advice team will tell you honestly, for nothing. Some horses are fed both; that's a conversation, not a guess.
The story behind Respirafix
Antoinette Foster - Owner & Product Formulator of Hi Form Australia
"Just over two years ago my beautiful warmblood gelding Coffee who is by Fidertanz was diagnosed with asthma and required constant medication in the form of Flixotide. We used the Breathe formula however even with high doses we could not manage the asthma without medication. This interfered with his work program, there were days when he was unrideable and many competitions and clinics were cancelled, he was working towards advanced level. Coffee was the motivation for myself and one of my other practitioners Karyn Campbell, who is a Naturopath and Equine Herbalist to formulate a new product specifically for asthma and COPD conditions. And so, the RespiraFix was born, Coffee has now been free from all drug medication for three months, not only has this formula kept the asthma under control but his lungs are stronger, and his work ability has improved dramatically. I have owned him for almost eight years, purchasing him as a very green 6-year-old. My good friend and sponsored rider David Boyle has trained him for a number of years and he is just as excited as I am in fact the whole team at Hi Form. If you have a horse diagnosed with Asthma or other respiratory conditions please check this product out, I have to say the success of this product fills our hearts with pure joy."

Breathe or RespiraFix?
Two products, one philosophy, different builds — here's how to choose. Both columns are good news; it's only a question of which horse you've got.
BreatheThe everyday one
RespiraFixThe comprehensive oneStill unsure? Our free nutrition advice team will tell you straight — it's what they're for.
Small scoop, serious formula
Mix well into slightly damp feed.
If you think your horse needs more than the standard rate — or you're not sure which half of the respiratory pair fits — that's exactly the conversation our free nutrition advice team is for.
When does my horse need RespiraFix in their bucket?
The moments it was made for...
- The environment is as managed as it can get — and you want the nutritional layer on top
- You've been struggling to get your horses breathing comfortable with medications alone
- You've tried other respiratory supplements with little or no effect
- Maintaining your horses respiratory health needs nutritional support
- The advice team has walked your set-up and suggested the step up
What it actually costs
From £1.90 a day for a 300kg pony on the 500g tub; a 500kg horse is £3.80 a day — about the price of the coffee you pick up on the way to the yard — and the biggest horses at 30g are £5.70. The 500g tub lasts a 500kg horse 25 days (a pony, 50), which makes it the natural first tub; the 2kg lasts the same horse 100 days and is the economical way to feed on.
Could we make it cheaper? Easily — we'd just concentrate less. Thirteen botanical extracts, one of them at 200:1, is the whole idea of this product; we'd rather explain the price than dilute the tub. And if the honest answer for your horse is 'Breathe is plenty' — or 'spend the money on dust-extracted bedding first' — the free nutrition advice team will say exactly that.

The comprehensive formula, on autopilot
A fresh pouch of RespiraFix delivered monthly — blended in our just-in-time batches, never warehouse-aged, with £2 delivery per pouch. Swap, pause or cancel whenever you like, and the swap matters here: plenty of horses run RespiraFix through the stabled months and step across to Breathe when the grass comes.
FAQs
We are always available to chat through your queries and questions. Just drop us a message or give us a call!
Breathe is the gentle, everyday product — most horses in ordinary stabled routines start there and stay there. RespiraFix is the stronger, more comprehensive formula for horses needing more focused support. Not sure? Describe your horse and your yard to the free nutrition advice team — it takes two minutes and costs nothing.
Yes — it sits happily alongside a daily foundation like Oxydane, and some horses are fed both halves of the respiratory pair on the advice team's steer. If the bucket is getting busy, send us the full line-up and we'll sense-check it for free.
Arithmetic, mostly. Thirteen botanicals can't fit in a 20g scoop as whole herbs, so each one is prepared as a concentrated extract — up to 200:1 — and the result is a powder. Breathe you can read with your eyes; RespiraFix you read on the label, where every extract and its concentration is printed. Mixed into slightly damp feed, the peppermint and liquorice handle the diplomacy with fussy eaters.
Vet first, always — and in this category especially. RespiraFix is a complementary feed supplement for maintaining health in healthy horses; it isn't a medicine and doesn't replace one. Any concern about your horse's respiratory health is a conversation for your vet, and once they're happy, we'll gladly help RespiraFix fit alongside their plan.
