Peppermint
A botanical in its own right — and the reason fussy eaters tend not to notice they're being supplemented.
Turmeric
A 100:1 extract standardised to 85% curcuminoids — one hundred kilos of root into every kilo we use.
Mineral Tissue Salts
The body's twelve essential minerals in finely prepared micro-doses, chosen for easy uptake. A Hi Form signature since 1990.
Rosehip
Nature's vitamin C larder, concentrated 10:1. A Hi Form favourite — you'll find it in Oxydane and ProflamAid Plus.
Siberian ginseng
A classic botanical with centuries of traditional use, supporting horses living busy, working lives. In Oxydane every day.

HI FORM OXYDANE
Anna Pichler’s 6 year old, The Fireball or Flummi at home (it means rubber ball in German) out of Franziskus (Ingrid Klimke’s famous stallion) needed some “transformation”. The before photo is the day before Oxydane and the after photo is one week later

Since 1990 · Thirty-five years, one rule
From one nutritionist in Australia to feed rooms across Britain — and the same rule the whole way: if it isn't good enough for people, it isn't good enough for horses.
One nutritionist, one conviction
Our journey starts with a simple idea
In Australia, equine nutritionist Antoinette Foster starts Hi Form with a rule that still governs every tub: if it isn't good enough for people, it isn't good enough for horses. Human-grade ingredients, no fillers — formed from more, from day one.
The formulas prove themselves
Patents, not promises
The early formulas earn their stripes on Australian yards and racetracks — ProflamAid Plus is patented, and veterans of that circuit still call it P+. The range grows the slow way: one well-made formula at a time.
A meeting at Spoga
The aisle that changed everything
At the Spoga horse fair in Cologne, Alice meets Hi Form — and can't understand why nobody in Britain can buy it. The labels do the convincing; the horses confirm it.
Hi Form comes to Britain
Hi Form UK is born
The first shipments land and British horses meet Oxydane. What starts as a few boxes becomes a business built the Hi Form way: advice first, sales second.
Never run out
The subscription begins
The monthly pouch service starts — fresh, just-in-time batches through the letterbox, so the daily essentials simply never run out. Many of those first subscribers are still with us.
Ask us first, buy second
Advice becomes the front door
The free nutrition advice form goes live on the website, turning what Alice was already doing by phone into the heart of the business: a practitioner-led look at your horse, your forage and your routine — even when the honest answer is "you don't need anything new". Thousands of conversations later, it's still free, and still the best place to start.
Out from behind the desk
A new chapter
Ownership stays in the family: Martin Matthews takes on ownership and oversight of the business, while Alice does what she's always loved most — front of house, looking after customers, answering the advice line, and turning up at the shows. Same formulas, same standards, same faces where it counts.
Have a question ? We are here to help.
The things most people want to know first. Anything else — call, message, or use the free advice form; a real person answers, usually one covered in horse hair.
What makes Hi Form different from other supplement brands?
Every ingredient is human grade and listed with Australia's TGA — our rule since 1990 is that if we wouldn't consume it, our horses don't either. No fillers, no binders, no by-products making up the weight, and every level printed on the label. Turn our tubs around and compare; we'd genuinely rather you did.
I don't know which product my horse needs. Where do I start?
With us, ideally — our free nutrition advice service is run by a practitioner-led team who'll look at your horse, forage and routine and tell you what's actually needed, even when the answer is "nothing new". Otherwise, most horses start with a daily foundation: Oxydane for horses in work, LeisureVit for the lighter life.
Is the nutrition advice really free?
Really. No obligation, no script, no commission-hungry follow-up calls. It's how we'd want to be treated, and it's the best route to the right product rather than just a product.
Can I feed more than one Hi Form product together?
Yes — the range is designed as a family, with a daily foundation underneath and targeted formulas alongside. If you're combining more than two, run it past the advice team so nothing overlaps.
Are your supplements safe for competing horses?
The range is formulated with clean sport in mind, made in a HACCP-certified, Feedsafe-accredited facility with batch traceability. See our Clean Sport page for the full picture.
How do subscriptions work?
A fresh pouch through the letterbox every month, made in just-in-time batches that never sit in a warehouse. £2 delivery per pouch, and you can swap, pause or cancel whenever you like — no small print worth squinting at.
How long does delivery take?
Orders are picked and sent quickly - order before 1pm and it will ship the same day via next day delivery. With free UK shipping over £100. Full details on our shipping page.
