Supplements are exactly that — a supplement to good management, correct work and veterinary care. Nothing on this page is a medicine and nothing here treats or cures a condition. If your horse is lame, sore, stiff after work or has a history of muscle problems, your vet comes first. Once you know what you're supporting, this guide will help you pick the right product, size and format.

What's in the Equine America joint and muscle range?
Single-ingredient basics
- Equine America Turmeric — from £12.50 (1.5kg), also 3kg £22.99. The lowest-cost way into the range and an easy one to add to a bucket feed.
- Equine America Glucosamine HCl 12000 — from £16.99 (1kg), 5kg £82.50. A straight glucosamine powder, useful if you want to control exactly what your horse is getting.
- Equine America MSM Powder — £29.99 (500gm). A single-ingredient MSM powder, often fed alongside glucosamine.
Combined joint and skeletal formulas
- Equine America Kentucky — £36.99 (1 litre). A liquid, so it mixes straight through a damp feed.
- Equine America Kentucky Advanced Joint Powder — from £57.99 (700g), 1.155kg £84.99.
- Equine America Formula 1 — from £139.50 (3.6kg), 10kg £349.50. The highest-priced option in the range; check the feeding rate before comparing cost per day.
- Equine America Better Bones — £67.50 (3.5kg). Aimed at horses where bone and skeletal support is the priority.
The Buteless range
- Buteless Paste — £21.50 (30ml). The smallest, simplest way to try it.
- Buteless Super Strength Powder — from £22.99 for the 10 Day Loading Pouch, then 1.5kg £60.50 and 5.5kg £164.99.
- Buteless Original Powder — from £37.99 (1kg), 3kg £88.50.
- Buteless Solution with Aqualox — from £42.50 (1 litre), 5 litre £150.99. The liquid version, for fussy feeders who spot a powder.
Muscle support
- Equine America More Muscle Pellets — from £47.50 (3kg), 10kg £126.50. Pelleted, so no powder at the bottom of the bucket.
- Equine America Tye Gard — from £58.50 (1 litre), 5 litre £252.99. If your horse has any history of muscle problems, talk to your vet before feeding.
- Equine America Vitamin E and Selenium — £31.50 (1kg). Selenium is one to be careful with — don't stack it with another selenium-containing feed or balancer without checking total intake.
Powder, liquid, pellets or paste — does the format matter?
It matters more than most people expect, because the best supplement is the one your horse actually eats.
| Format | Best for | Watch out for |
|---|---|---|
| Powder | Value per kg, easy to scale up or down | Can be left at the bottom of the bucket by fussy feeders; damp the feed |
| Liquid | Mixing invisibly through a damp feed | Needs a measure; heavier to post and store |
| Pellets | Clean feeding, no dust, good palatability | Fewer size options than powders |
| Paste | Short-term or one-off use, or trying a product before buying a tub | Highest cost per dose over a long period |
How do I work out the real cost of a supplement?
Never compare tub prices alone — compare cost per day. Take the pack price, divide by the number of days it lasts at the feeding rate on the label for your horse's weight, and you'll often find a larger tub of a mid-priced product works out cheaper than a small tub of a budget one. Loading rates matter too: some products are fed at a higher rate for the first week or two, which uses up a tub faster than the maintenance rate suggests.
Frequently asked questions
Which Equine America joint supplement should I start with?
If you're new to supplementing, a single-ingredient product makes it easier to see what you're paying for — Equine America Turmeric from £12.50 or Glucosamine HCl 12000 from £16.99 are the usual starting points. If you'd rather have several ingredients in one scoop, look at Kentucky at £36.99 or Kentucky Advanced Joint Powder from £57.99. Ask your vet first if your horse is showing any lameness or stiffness, so you're supporting the right thing.
How long does a joint supplement take to make a difference?
Feed supplements aren't fast-acting and results vary from horse to horse. Most owners feed a full tub before judging, and many products have a higher loading rate for the first week or two followed by a lower maintenance rate — check the label for the exact schedule. Keep a note of your horse's work and how they feel, and review it with your vet rather than judging on one good or bad week.
Are these supplements suitable for competition horses?
Competition rules on feed ingredients differ between governing bodies and change over time, so always check the current prohibited-substances guidance for your discipline and confirm the specific product and batch with the manufacturer before you compete. If in doubt, leave enough of a gap or choose a product the organisers have confirmed is acceptable — the responsibility for what's in your horse sits with you.
Can I feed two supplements at the same time?
You can, but check the labels for overlap first. Feeding a joint formula alongside a balancer or a second supplement can easily double up on the same ingredients — selenium in particular has a safe upper limit, so Vitamin E and Selenium shouldn't be stacked with another selenium source without adding up the total. If you're combining products, run the plan past your vet or an equine nutritionist.
What's the difference between the Buteless products?
Mainly format and strength. Buteless Paste (£21.50, 30ml) is the small, short-term option; Buteless Original Powder starts at £37.99 for 1kg; Buteless Super Strength Powder starts at £22.99 for the 10 Day Loading Pouch and goes up to 5.5kg; and Buteless Solution with Aqualox from £42.50 is the liquid, which suits horses that pick around powders. Compare the feeding rates on each label before deciding which is best value for your horse.
How much do Equine America joint and muscle supplements cost?
In this collection of 14 products, prices start at £12.50 for Equine America Turmeric (1.5kg) and run up to £349.50 for the 10kg size of Formula 1. Many of the joint powders and liquids sit between £30 and £70 for a standard tub or bottle. Larger sizes usually cost less per day, so once you've settled on a product it's worth buying the bigger pack.
