Hooves are the weight-bearing structure of a horse’s limb—they absorb shock, protect the internal tissues of the foot (living tissue, bone, tendons, blood vessels), and enable propulsion during movement. A healthy hoof has a thick, hard wall free of cracks, a flexible yet resilient sole, and a well-developed frog. Hoof quality is determined 70% by genetics and 30% by diet, care, and environment. The hoof wall is composed of tubular keratin—a sulfur-rich fibrous protein whose synthesis depends directly on the intake of biotin (vitamin B8, an enzymatic cofactor for keratin synthesis), sulfur-containing amino acids (methionine, cysteine), and minerals (zinc, copper, silicon).
Biotin (vitamin B8, 15 to 30 mg/day) is the best-documented supplement for improving hoof quality—randomized studies show a measurable improvement in wall hardness and growth after 6 to 9 months of continuous supplementation, since the hoof wall takes 9 to 12 months to completely renew itself. Zinc is an essential cofactor for enzymes involved in the synthesis of keratin and collagen, and a deficiency manifests as soft, brittle hooves with slowed growth. Horsetail (Equisetum arvense, rich in bioavailable organic silica) strengthens the mineral structure of keratin and improves the elasticity of the hoof wall. These active ingredients are available in powder form to be mixed into the feed or as liquid oral supplements.
Topical hoof care products fall into two main categories—nourishing/softening and waterproofing/protective:
Stinging nettle (Urtica dioica, silica + minerals) is used in equine herbal medicine to strengthen the keratin in hooves and manes—its bioavailable minerals complement the action of horsetail.
Laminitis (equine laminitis) is an acute inflammation of the sensitive laminae connecting the hoof wall to the third phalanx—in severe cases, this phalanx may rotate or sink inward, causing irreversible damage. The main causes are dietary (excess fructans in spring grass, carbohydrate overload), metabolic (equine metabolic syndrome, PPID/Cushing’s), or mechanical (intense exercise on hard ground). Preventive oral solutions for laminitis (active ingredients targeting carbohydrate metabolism and circulation in the foot) are recommended for at-risk horses. Collagen (type I, hydrolyzed) supports the integrity of the sensitive laminae and the connective tissue of the foot—a preventive nutritional approach for predisposed horses.
A daily routine is just as important as supplementation. Trimming (removing debris, mud, and manure) should be done morning and evening, checking for any foreign objects lodged in the frog or sole. A visit from the farrier every 6 to 8 weeks (for shod horses) or every 4 to 6 weeks (for barefoot horses) is essential to maintain proper alignment and rebalance the hoof wall. A suitable surface—neither too dry, too wet, nor too hard—is the final factor determining the long-term health of the hooves. Hyaluronic acid is used in intra-articular injections into the joints of the foot to treat arthritis and improve synovial lubrication.
Several situations require immediate intervention by a veterinarian or a qualified farrier. Acute laminitis (severe pain, the horse standing on its heels, warmth in the hoof, palpable digital pulse) is an absolute veterinary emergency—every hour lost worsens the damage to the hoof walls. A hoof abscess (sudden acute lameness, localized warmth, strong digital pulse, sometimes a purulent fistula) requires emergency veterinary trimming for drainage. Advanced frog rot (foul odor, black decomposing tissue in the center of the hoof) requires sustained antiseptic treatment and a re-trimming of the hoof. Hyaluronic acid injected by a veterinarian into the coffin joint relieves chronic joint pain in the foot and improves synovial lubrication—a complementary intervention to topical hoof care. Finally, a comprehensive nutritional assessment (zinc, copper, biotin, silicon) can reveal deficiencies that may be causing chronic poor hoof quality.
