How Effective Is Biotin for Horses?

Several research studies on the use of biotin for horses showed B vitamin supplements created stronger hooves as they grew out. Biotin supplements also increased the growth rate of hooves, which take between eight and 15 months to regenerate. Researchers are not certain why biotin for horses addresses hoof problems, but recommend lifelong treatment to prevent the re-occurrence of cracked, dry hooves that might begin crumbling and become tender.

Biotin exists in most cells and converts food to energy. This B vitamin also plays a vital role in metabolizing fats, carbohydrates, and protein. Adrenal and thyroid glands use biotin to stabilize nerves, promote growth, and build a healthy reproductive system.

The vitamin is found naturally in some animal feed, such as alfalfa, oats, soy meal, and molasses, but only small amounts might be absorbed in a horse’s intestinal tract. The large intestine, or hind gut, absorbs biotin and other nutrients via bacteria produced when feed ferments. Some studies show the hind gut only absorbs water, which might lead to a biotin deficiency.

When biotin for horses is given as a supplement, it might allow absorption of the vitamin in the upper digestive tract, where most nutrients are used. Most commercial horse feed contains biotin and other vitamins in small amounts. Supplements of biotin should include at least 15 milligrams per day to address hoof problems, researchers found.

These supplements do not treat old growth, but create stronger hooves as they grow out. The rate of growth varies by breed and environmental factors. Hooves grow slower in cold climates and faster when a horse’s body temperature rises. Hooves of working horses also grow faster.

Hoof growth starts at the coronary band, an area on the top of the hoof where hair exists. The condition of the hoof is measured by hardness, form, and strength to withstand the horse’s weight, which is borne by the wall of the hoof. A hoof that spreads out might not be receiving adequate vitamins and minerals from the blood supply, especially biotin, which is a water-soluble vitamin excreted in the urine.

In addition to biotin for horses, most hoof supplements contain iodine, zinc, methionine, and calcium. Horses receiving these supplements showed improvement in hoof health within six months. When biotin levels were decreased or discontinued, hooves began deteriorating in most horses studied. Equine veterinarians advise continued use of biotin for horses to correct hoof problems and prevent relapse to prior conditions.

Biotin, a B-vitamin, is known to support healthy hoof growth and improve the quality of horses' hooves. It aids in the metabolism of fats, proteins, and carbohydrates, contributing to overall health. Studies have shown that biotin supplementation can lead to improved hoof hardness and integrity, which is crucial for equine athletes and working horses.

Results from biotin supplementation can take several months to become apparent. Hoof growth in horses is slow, and it may take 6 to 12 months of consistent biotin intake before significant improvements are seen. This is because the supplement aids in the growth of new, healthier hoof tissue, which takes time to develop and replace the old.

The recommended dosage of biotin for horses varies, but it generally ranges from 15 to 30 milligrams per day. According to research, a daily dose of 20 milligrams of biotin is often effective for improving hoof quality. However, the specific needs may vary based on the horse's size, diet, and hoof condition, so it's best to consult with a veterinarian.

Biotin is considered safe for horses and has a low risk of toxicity. However, excessive supplementation is not beneficial and can be wasteful. While there are no well-documented cases of biotin overdose in horses, it's always prudent to adhere to recommended dosages and consult with a veterinarian before making significant changes to a horse's dietary regimen.

Side effects from biotin supplementation in horses are rare, as biotin is a water-soluble vitamin and excess amounts are typically excreted in urine. However, introducing any new supplement should be done gradually to monitor for any adverse reactions, and it's important to ensure that the supplement does not unbalance the overall diet.

Biotin supplementation is not necessary for all horses. Many horses receive adequate biotin through their diet, particularly if they have access to good-quality forage and a balanced feed. Supplementation is generally recommended for horses with poor hoof quality, those recovering from hoof injuries, or those with increased hoof growth demands due to their work or environment.
