The Australian supplement market has exploded in recent years, and sorting through what your horse actually needs versus what the marketing says they need is genuinely tricky. This list cuts through the noise — every product here is in stock at iRide EQ right now, with real prices in AUD and honest commentary on what each one does (and doesn't do).
Whether you're dealing with a dull coat, brittle hooves, a fussy eater, or a horse that loses condition over winter, the right supplement can make a measurable difference. But here's the honest truth: no supplement replaces good foundational feeding. Quality forage, clean water, and a balanced diet come first. Supplements fill gaps, they don't build the house.
The horse supplements range at iRide EQ covers everything from daily vitamin and mineral balancers to targeted gut, coat, hoof, and calming products. Australian brands like Equidae and Value Plus feature heavily, which means no import delays and consistent supply. Let's walk through the top 10.
Supplements fill nutritional gaps — they don't replace quality forage and a balanced diet.
1. 30 Day Equine Supplement Packs
Price: $115.50 AUD | Brand: Equidae
If you're new to supplementing and feeling overwhelmed, the 30 Day Equine Supplement Packs are where I'd start. You get a curated month's supply covering the essentials — vitamins, minerals, and gut support — all dosed and ready to go. It takes the guesswork out of it, which is exactly what most riders need when they're already juggling work, riding, and stable chores.
The packs are designed by Equidae, an Australian company that formulates specifically for Australian conditions and forage profiles. That matters more than people realise — supplement requirements differ depending on soil deficiencies in your region, and a locally formulated product accounts for that. At $115.50 for a month, it works out to under $4 a day, which is reasonable for comprehensive coverage.
30 Day Equine Supplement Packs — $115.50 AUD at iRide EQ.
2. NUTRIblend — Vitamin & Mineral Supplement
Price: $109.50 AUD | Brand: Equidae
NUTRIblend is the daily vitamin and mineral balancer I'd reach for if your horse is on pasture or hay without a fortified feed. Australian soils are notoriously deficient in selenium, copper, and zinc — and a good balancer covers those gaps without overdoing it. The 1.5kg tub lasts a while too, which softens the price tag.
I like that Equidae doesn't load this with fillers. It's a concentrated powder, so you're feeding a small scoop rather than a big handful. That makes it easy to mix into a feed and means a tub goes the distance. If your horse has a dull coat, low energy, or just looks "off" despite good feed, this is the first thing I'd try.
NUTRIblend — daily vitamin and mineral balancer, $109.50 AUD.
3. GUTonic — Gut & Digestion Support
Price: $109.50 AUD | Brand: Equidae
Gut health is one of those things that gets talked about constantly in the supplement world, and for good reason. A horse with compromised gut function won't absorb nutrients properly, so everything else you feed becomes less effective. GUTonic is designed to support the hindgut and may help horses prone to ulcers or digestive upset.
Here's the honest caveat: probiotic research in horses is still evolving. I'd use "may support" rather than "proven to fix" when talking about gut supplements. What I can say is that horses on GUTonic tend to eat better and maintain condition more easily through stress periods like travel, competition, or feed changes. At $109.50, it's not cheap, but gut issues are expensive to treat once they escalate.
GUTonic — gut and digestion support, $109.50 AUD.
The rider's take: The first time I put my thoroughbred on GUTonic, it was a last resort. He'd been dropping condition despite a good feed regime, and his appetite was rubbish. Three weeks in, he was cleaning up every meal and his coat had a shine I hadn't seen in months. Was it the GUTonic alone or just the season changing? Hard to say definitively, but I keep it in his routine now and the difference is noticeable enough that I'm not willing to stop to find out.
4. Fixine BioBoost — Probiotic Top-Up
Price: $88.00 AUD | Brand: CAN Animal Care
Fixine BioBoost is a concentrated probiotic paste that sits somewhere between a daily supplement and a targeted treatment. It's the kind of product I'd reach for after a course of antibiotics, a colic episode, or any event that disrupts the hindgut microbiome. The 80cc tube is easy to administer directly into the mouth, which means you know the horse actually got the dose.
At $88, it's a mid-range investment for a targeted product. I wouldn't use it as a daily maintenance supplement — that's what GUTonic is for. But as a boost after illness, travel, or dietary changes, it's a useful tool in the kit. Always check with your vet before adding probiotics to a horse with ongoing digestive issues, as they'll have a view on timing and dosage.
Fixine BioBoost — concentrated probiotic paste, $88.00 AUD.
5. DERMAblend — Skin & Coat Supplement
Price: $109.50 AUD | Brand: Equidae
A dull coat is one of the most common reasons riders reach for a supplement, and DERMAblend is specifically formulated for skin and coat health. It contains omega fatty acids and other nutrients that support coat condition from the inside out. The difference shows up in about 4 to 6 weeks — this isn't an overnight fix.
I'd pair this with good grooming brushes and a proper currying routine. Supplements and elbow grease work together; neither does the job alone. For horses with dry, flaky skin or a coat that won't hold a shine regardless of grooming, DERMAblend is worth a try. Check out our coat health range for complementary options.
DERMAblend — skin and coat support, $109.50 AUD.
6. Biotin — Hoof Growth Supplement
Price: $76.50 AUD | Brand: Value Plus
Biotin is the supplement most farriers will recommend for horses with cracked or brittle hooves. The research is fairly clear: 15 to 20mg per day, consistently, for 6 to 12 months. That's the part people miss — biotin is not a quick fix. You need to commit to it long-term to see hoof wall improvement.
The Value Plus Biotin is a 5kg tub, which at $76.50 is excellent value for an Australian-made product. Value Plus is a genuinely local brand (you can find them at valueplus.net.au), which means no supply chain delays. If your horse has shelly hooves, pair this with regular farriery and a good horse health routine. For more on hoof care, check our guide to Top 10 Hoof Care Essentials for 2026-2027.
Value Plus Biotin — 5kg tub for hoof support, $76.50 AUD.
7. AMINOpaste — Recovery & Topline
Price: $28.00 AUD | Brand: Equidae
AMINOpaste is an amino acid paste designed to support muscle recovery and topline development. I'd use this post-competition, after a hard schooling session, or for horses struggling to maintain topline condition. At $28, it's one of the most affordable targeted supplements in the range.
The paste format means you can dose it precisely when your horse needs it, rather than committing to a daily powder. That makes it practical for competition riders who only supplement around intense work periods. It's also easy to keep in a gear bag for shows.
AMINOpaste — recovery and topline support paste, $28.00 AUD.
8. HYDROpaste — Electrolyte Paste
Price: $28.00 AUD | Brand: Equidae
Electrolytes are essential for horses in work, particularly in Australian summer heat. HYDROpaste delivers electrolytes in a convenient oral paste format, which is ideal for competition days, long transport, or any time your horse is sweating heavily. The key with electrolytes is that they're for horses actually in work or competing — a horse standing in a paddock doesn't need them.
At $28, it's a budget-friendly option that lives in your show kit. I'd use it alongside access to fresh water, never as a replacement. For horses that won't drink at competitions, electrolyte paste can actually encourage drinking by stimulating thirst response.
HYDROpaste — electrolyte paste for hot weather and competition, $28.00 AUD.
9. ZENpaste — Stress Support Paste
Price: $28.00 AUD | Brand: Equidae
ZENpaste is Equidae's calming support paste, designed for horses that get anxious about travel, competition, farrier visits, or other stressful events. The format is a pre-measured paste, so you dose it about 30 to 60 minutes before the stressful situation.
Here's the honest truth on calming supplements: the evidence is mixed. Tryptophan, a common ingredient in calming products, has no proven calming effect in horses and may actually increase excitability in some animals. Magnesium-based products may help if your horse is genuinely magnesium-deficient, but won't do much otherwise. I'd treat ZENpaste as a tool in the kit, not a miracle cure. If your horse has genuine anxiety issues, talk to your vet or an equine behaviourist.
ZENpaste — stress support paste, $28.00 AUD.
10. Calming Paste 30ML — Budget Calming Option
Price: $16.75 AUD | Brand: Value Plus
At $16.75, this is the most affordable calming option in the range. The Value Plus Calming Paste comes in a 30ml tube and is designed for single-use situations — float loading, vet visits, first outings. It's the kind of thing you keep in the truck "just in case."
The same caveat applies here as with all calming supplements: manage your expectations. For a genuinely anxious horse, no paste will replace proper training, desensitisation, and sometimes veterinary intervention. But for a mild case of pre-show nerves, a $16.75 tube is a low-risk thing to try. Don't rely on it as your only strategy though — rider training aids and consistent groundwork do more for a horse's confidence than any supplement.
Value Plus Calming Paste 30ML — budget calming option, $16.75 AUD.

Frequently Asked Questions
What supplements do horses need?
Most horses on good quality pasture or hay with a balanced feed don't need much beyond a vitamin and mineral balancer to cover Australian soil deficiencies (selenium, copper, zinc). Horses in harder work may benefit from electrolytes and recovery supplements. Always start with a vet assessment before adding supplements.
Do horse calming supplements actually work?
The evidence is mixed. Tryptophan-based products have no proven calming effect in horses and may increase excitability. Magnesium may help if your horse is genuinely deficient. For real anxiety issues, consult your vet or an equine behaviourist rather than relying on supplements alone.
Are horse supplements for arthritis worth it?
Joint supplements containing glucosamine, chondroitin, or hyaluronic acid may support joint comfort in older horses or those in heavy work. The research isn't definitive, but many riders report improvements. Talk to your vet about whether joint supplementation is appropriate for your horse's specific situation.
Can supplements help with horse gut health?
Probiotic and prebiotic supplements may support hindgut function, particularly after illness, antibiotics, or dietary changes. They're not a cure for ulcers or serious digestive conditions. If your horse has ongoing gut issues, get a veterinary diagnosis first.
What's the best supplement for horse weight gain?
Weight gain comes primarily from increased calorie intake (more forage, added oil, or a conditioning feed). Supplements like AMINOpaste can support muscle recovery and topline, but they won't cause weight gain on their own. Address the diet first, then supplement to fill gaps.
Do horses need biotin for hoof growth?
Research supports biotin at 15 to 20mg per day for 6 to 12 months to improve hoof wall quality in horses with brittle or shelly hooves. It's not a quick fix — consistency over months is key. Pair with regular farriery for best results.
Should I consult a vet before giving my horse supplements?
Yes. Supplements can interact with medications, and some ingredients are contraindicated for certain conditions. A vet can also help you identify actual deficiencies through blood work rather than guessing. Supplements complement a good diet — they don't replace veterinary care.
