  • Promote healthy skin and hair
  • 3.3lb (1.5kg) tub gives approximately 1-month supply
Product Description: 


The number one ingredient in any hoof supplement must be Biotin, as by far the most scientific evidence for an effect on hoof growth and quality exists for this nutrient, so 4Feet Plus contains a very high level of bioavailable D-Biotin (75mg/day for an 1100lb horse). As Biotin is absorbed from the hindgut, 4Feet Plus also contains a high dose of a protected live yeast to help ensure a healthy hindgut environment. Further, 4Feet Plus contains the needed minerals for proper hoof development (both internal and external tissues), at the ratios that meet scientific recommendations. With methionine and MSM, we provide the sulfur building blocks needed for proper keratin and collagen creation, and the MSM provides anti-inflammatory support to help maintain blood flow to the hooves. See below for the science behind each ingredient.


Poor hoof condition is common in all types of horses and ponies and can lead to practical problems such as splitting of the hoof and losing shoes, as well as foot pain and lameness.


Changes in hoof growth and or quality can take 3-6 months to be visible and between 9-12months for the entire hoof to be replaced with new growth, so the time to supplement is ideally before hoof problems develop. When new hoof begins to grow in, the new hoof growth below the coronet band should be smooth and the growth lines should be vertical and horizontal. It’s not uncommon when the new hoof has grown in and a small band of old hoof remains at the ground, the older, weaker, and less structural hoof portion may break off more readily (often after 8-10 months of supplementing and new hoof growth). This is normal, as the stronger more stable hoof grows in.

The Science Behind Each Active Ingredient 

Biotin is an essential B vitamin (B-7) that has been shown to be the most important factor in healthy hoof development. Horses must obtain biotin either from their diet, from supplements, or (with a healthy hindgut) as a product of specific bacteria living in thier hindgut.  

Saccharomyces cerevisiae is the species of yeast shown to have positive impacts on hindgut health by aiding digestion and helping stablize the hindgut microbiome.  By supporting hindgut health, the horse is better adapt at both digesting and absorbing the nutients, vitamins, and minerals needed for healthy hoof growth.

Organic Zinc is included as horn is mainly composed of a protein called keratin (a structural protein composed of fibers that makes up horn, skin, hair, wool, feathers and nails), and Zinc is vital for protein metabolism.

Copper deficiency can have an adverse effect on horn and hair quality. The correct ratio between Zinc and Copper is important, as these two trace elements interact.

Manganese is integral to formation of the internal structures of the hoof. Manganese is low in grains, and the amount provided by forage can vary dramatically. In addition, manganese is poorly absorbed, so deficiency is not uncommon.

Methionine is a key amino acid for hooves, as the production of horn involves the interaction between Methionine and keratin to produce a strong structure.

MSM is a bioavailable source of sulfur, and sulfur in turn is present in high amounts in keratin.

QUESTION: Does Feeding a D-Biotin and Calcium Supplement Improve Hoof Quality?


  • Poor hoof condition is common in all types of horses and ponies and can lead to practical problems such as splitting of the hoof and losing shoes as well as foot pain and lameness.
  • Long-term feeding of biotin for 5-10 months has previously been shown to improve hoof horn quality and strength1-4.

Aim of Study

To determine if oral supplementation of D-Biotin and calcium for three months improves hoof quality

Study Design

  • Prospective clinical case series = a group of horses selected for a particular reason (poor feet in this study) was followed over several months.
  • Blinded = the clinician grading foot photographs was unaware of the date taken and any client or horse details.

Study Outline

Twelve horses with poor hoof condition were fed 4Feet (Science Supplements) at the recommended dose, for 3 months, delivering 25mg high quality, highly bio-available Biotin daily. Horse owners submitted photographs of all 4 feet of their horse to document hoof quality at the start of the trial and once a month throughout the trial. At the end of the three months, the photographs were blinded for horse, owner and month and scored by an equine orthopedic veterinary specialist, Dr Rachel Murray (Rossdales Equine Hospital). This scoring system grades eleven separate features of the hoof and has been previously validated5 (Table 1, Figure 1). The median score of all four feet was used for each hoof feature at each month time-point for data analysis as any effect of the hoof supplement would be on all feet.

 Study Results

  • All horses ate the supplement without palatability issues.
  • Median hoof score decreased (i.e. hoof quality improved) for the features dorsal hoof wall, hoof wall surface, wall solar margin and shoeing from the start of the trial to 3 months (Figure 2).

Take Home Message

  • Feeding a Biotin and calcium oral supplement daily for 3 months improved the score of certain hoof quality features. Feeding for a longer period than three months may be required for some hoof parameters to improve.
