Digestive supplements and gut balancers for horses support the digestive system to help them cope with a number of transitions throughout the year, such as increased turnout in the spring, change of grazing quality in the winter or the introduction of a different forage, such as haylage, to the diet. 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 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.
Best digestive supplements and gut balancers for horses: what are your options?
Here is a selection of the best gut balancers for horses that are currently available, including 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.

How to choose the best gut balancer for horses
Most gut balancers are formulated to help maintain a stable environment in the gut, which keeps digestion healthy, regular and efficient, despite changes in diet and environment. Some digestive supplements target other specific areas of the digestive system, such as buffering stomach acid, so we’ve rounded these up in a guide to the best gastric supplements for horses. Knowing why you want to feed your horse a digestive supplement will help you choose the right one for him.
Common ingredients of gut balancers include…
- probiotics, which are often referred to as “good bacteria”
- prebiotics, which are the “food” for probiotics, helping them to work effectively
Consider the form the supplement takes – digestive supplements can come in liquid, powder and pellet forms. Your horse may have a preference to one over another, which could make all the difference as if he won’t eat it, your horse won’t receive the benefit.
Cost is another consideration – we’ve calculated the daily cost of all the supplements featured in this guide to help you compare them easily. To make it as comparable as possible, we’ve used the smallest tubs available, but you’re better off buying a larger volume of supplement if you can as the daily cost can become significantly lower.
If you compete with your horse then it is important you make sure any supplements you use do not contain any prohibited substances.
