Digestive supplements: what’s on the market?

  • Horse & Hound is supported by its audience. When you purchase through links on our site, we may earn commission on some of the items you choose to buy.
  • Digestive supplements support your horse’s digestive system to help him cope with a number of transitions throughout the year, such as increased turnout in the spring or change of grazing quality in the winter. These changes can leave some horses’ digestive systems struggling, leading to a reduction in efficiency, loose droppings and other digestive upsets.

    Often containing soothing herbs as well as pre- and probiotics, these supplements aim to maintain a healthy digestive system, provide a buffering effect against excess stomach acid and promote a normal population of bacteria to make sure your horse is getting the most out of what he eats while keeping him comfortable.

    Common ingredients of digestive supplements include…

    • probiotics, which are often referred to as “good bacteria”
    • prebiotics, which are the “food” for probiotics, helping them to work effectively

    If you compete with your horse then it is important you make sure any supplements you use do not contain any prohibited substances.

    Digestive supplements for horses: what are your options?

    Here is a selection of the best digestive supplements for horses that are currently available below in our alphabetical list, which includes the manufacturers’ descriptions of their products…

    NB: Cost per day has been calculated using the maintenance measure for a 500kg horse in light work (where there was variation) and the RRP of the smallest available tub. Some products require loading doses and some horses will require a higher dose, which will increase the cost per daily measure, while buying a larger tub will likely decrease it – these costs per day are a guide only.
