Horse First Supplements
Horse First is an Irish-made range of single-purpose horse supplements, each formulated to target one job — calming, hooves, joints, coat, digestion or electrolytes — so you can feed exactly what your horse needs and nothing it doesn't.
Horse First is built around focused daily feed supplements with high levels of active ingredients. At Just Horse Riders we stock around 19 Horse First supplement lines spanning calming (Relax Me), hoof (Hoof First), coat and condition (Cuppra, Exselent E), joints and mobility (Keep Me Sound, My Joints Plus), digestive and gastric support (Acid Aid, Garlic & More) and electrolytes (Heavy Sweat), with prices from £6.74.

What does Horse First make?
Horse First produces focused feed supplements, each built around a single goal rather than a one-size-fits-all scoop. The range we stock covers calming, hoof, coat and condition, joints and mobility, digestive and gastric comfort, electrolytes and general vitality. Supplements support a horse's diet alongside good management — they are not medicines. If your horse has a specific health concern, speak to your vet before starting or changing any supplement.
Which Horse First range is right for me?
Pick by the job you want the supplement to do. The table below is a quick starting point — every yard and every horse is different, so use it as a guide rather than a rule.

| Calming | Fizzy, anxious or spooky horses; travel and competition days | Relax Me (£19.65); Relax Me Now single scoop (£9.12) |
| Hoof | Weak, cracked or slow-growing hooves | Hoof First (£19.65) |

How do I choose the right size and dose?
Most Horse First supplements come in more than one tub size, plus small single-serve packs (such as Relax Me Now and Heavy Sweat Now) that let you trial a product before committing to a full tub. Always follow the feeding rate on the pack and introduce any new supplement gradually. Avoid doubling up on the same active ingredient across several products, and check with your vet if your horse is competing under rules, is pregnant, or is on medication.
Which Horse First products do we recommend?
- Relax Me — from £19.65 — a popular daily calmer with a double-action gut and nervous-system formula.
- Hoof First — from £19.65 — high-strength biotin and minerals for horses working on hoof quality.
- Cuppra — from £12.91 — a straightforward copper top-up to support coat colour and shine.
- Garlic & More — from £17.87 — a herbal blend for everyday immune and digestive support.
- Keep Me Sound — from £24.51 — an all-in-one daily supplement covering several bases at once.
- Acid Aid — from £33.07 — aimed at horses prone to gastric discomfort; pair with vet advice.
Care, feeding and related kit

Horse First supplements FAQ
How much do Horse First supplements cost?
In-stock Horse First supplements currently range from £6.74 for a single-serve electrolyte sachet up to £156.55 for the largest joint tub. Most everyday daily tubs sit between roughly £12 and £50, and many lines offer more than one size.
Are Horse First supplements safe to feed every day?
Yes — they are daily feed supplements designed to be fed at the rate printed on the pack. Introduce any new supplement gradually and avoid feeding two products with the same active ingredient at once. If your horse has a health condition or is on medication, check with your vet first.
Which Horse First supplement should I use for a fizzy horse?
Many riders start with Relax Me (from £19.65), a daily calmer that works on both the gut and the nervous system. For occasional situations such as travel or a competition, the single-scoop Relax Me Now (from £9.12) lets you feed a top-up on the day. Always check current competition rules on calming ingredients.
How long until I see results?
It varies by product and by horse. Hoof supplements such as Hoof First work as the hoof grows, so give them several months. Coat, condition and calming products are usually fed over a number of weeks. Consistency and correct dosing matter more than short bursts.
Can Horse First supplements treat or cure a health problem?
No. These are feed supplements that support a balanced diet and normal function — they are not medicines and are not intended to diagnose, treat or cure any condition. If your horse is unwell, lame or off its feed, contact your vet.
Do you deliver Horse First supplements for free?
Yes — UK delivery is free on orders over £50, with next-day dispatch available on eligible items ordered before 4pm. Smaller orders ship at a standard rate shown at checkout.
