A horse’s health needs span multiple systems — from daily digestive vitality and coat condition, to joint mobility under work, nervous energy and focus in training, and the structural integrity of the hooves that carry them. The right supplement targets the right system, and choosing between them comes down to understanding your horse’s primary need. Our Horse Vitamins & Supplements collection covers every key area of equine health. We’ve compared four standout picks — from a foundational daily tonic to a high-strength joint formula, an award-winning calming supplement, and a comprehensive hoof builder — so you can find the right support for your horse.
1. Hilton Herbs Apple Cider Vinegar with Mother – 5L – £28.30
The Hilton Herbs Apple Cider Vinegar with Mother is the most foundational and broadly applicable supplement in this comparison — a daily tonic that supports overall vitality rather than targeting a single system. Human-grade, un-pasteurised, and crafted from whole apples, it retains the “mother” — the naturally occurring colony of beneficial bacteria and enzymes that makes raw apple cider vinegar nutritionally potent. Rich in natural minerals including potassium, phosphorus, and calcium, it supports digestion, coat condition, and general wellbeing when added to feed or water daily. With a minimum 5% acidity level and a 5L container for long-lasting use, it’s the most economical and versatile supplement in this comparison. Suitable for horses, ponies, and domestic pets alike.
Best for: Owners who want a simple, natural daily tonic to support overall vitality, digestion, and coat condition across horses and ponies of all ages.
Key nutrients: Potassium, phosphorus, calcium, natural enzymes | Size: 5L | Formula: Human-grade, unrefined, unpasteurised, with mother
Standout feature: Unrefined with the “mother” intact — the most foundational and broadly applicable daily supplement in this comparison, supporting digestion, coat, and vitality from a single bottle.
2. NAF Glucosamine 12,000 Plus with MSM – 900g – £32.52
The NAF Glucosamine 12,000 Plus with MSM is the joint health specialist in this comparison. NAF (Natural Animal Feeds) is one of the UK’s most respected equine supplement brands, and this high-strength formula delivers 12,000mg of Glucosamine Sulphate — the most clinically recognised building block for cartilage maintenance — alongside MSM (methylsulfonylmethane), a sulphur-rich compound that works synergistically with glucosamine to support connective tissue integrity and flexibility. The combination addresses both the structural and functional aspects of joint health, making it the most targeted and scientifically grounded joint supplement in this comparison. The 900g tub provides a consistent daily supply for horses in regular work or those showing early signs of joint stiffness.
Best for: Horses in regular work, competition horses, or those showing signs of joint stiffness who need high-strength glucosamine and MSM support.

Its bio-available magnesium base addresses one of the most common nutritional deficiencies linked to nervous behaviour in horses, combined with a unique blend of calming herbal extracts that support relaxation and focus without sedation. Scientifically trialled and proven to support a calm, attentive demeanour, it’s audited under the BETA NOPS scheme — making it fully compliant for FEI competition use, a critical distinction for competitive riders. Safe for daily use across all horses and ponies. The 1.5kg tub provides a generous supply for consistent long-term use. The most rigorously validated and competition-appropriate calming supplement in this comparison.

The NAF Biotin Plus Hoof Supplement is the most comprehensive and longest-lasting specialist supplement in this comparison — and the only one focused entirely on hoof health. Delivering 15mg of biotin per daily serving — the high-strength dose recommended for meaningful hoof improvement — it’s enriched with MSM and Methionine (sulphur-containing nutrients essential for strong hoof keratin formation), plus Zinc and Calcium for structural mineral support. The result is faster, more resilient hoof growth with a tougher wall that resists cracking and chipping. The 8kg tub provides 160 days of supply — the most generous quantity in this comparison by far — making it the most economical choice per day for owners committed to long-term hoof improvement. The most specialised and structurally targeted supplement in this comparison.
