Max Gut-Health – 4,5 kg


Healthy gut - Healthy horse.

Max Gut-Health is a unique combination of calcareous marine algae and a highly active live yeast, designed as a probiotic to support a healthy gut environment in horses.


Max Gut-Health’s acts on the gut microflora to:

1. Promote the growth of fibre digesting bacteria

Horses do not have the necessary enzymes to break down fibre and rely on the large population of bacteria present in the hind-gut to carry this out through a process of fermentation. This results in the production of volatile fatty acids that provide a significant source of 'slow release' energy for all horses irrespective of age, breed or workload.
When horses undergo a period of stress fibre fermentation is often decreased. Therefore, promoting the growth of fibre digesting bacteria in the gut reduces the extent of this reduction and helps to maintain gut and animal health.

2. Reduce acid accumulation in the hindgut by competing with lactic acid forming bacteria

The inclusion of concentrates in the horse’s diet is often essential to meet energy, vitamin and mineral requirements. However, when undigested starch and sugars from concentrates reach the hindgut, the microbial fermentation process produces a higher level of lactic acid. This creates a more acidic environment in the hindgut (lowering the pH).
The live yeast within Max Gut-Health competes with lactic acid forming bacteria for sugars in the hindgut to reduce the acid load helping to maintain the correct pH balance.


In addition to the gut health benefits Max-gut health provides a source of bioavailable magnesium and calcium

Magnesium plays an important part in nerve and muscle function. Horses deficient in this important element can show signs of nervousness, wariness, excitability, and muscle tremors; magnesium is often provided for its calming influence on equine. Many magnesium sources aren’t fully bioavailable to the horse meaning that this mineral largely bypasses absorption and is excreted via the faeces, which if in excess can result in diarrhoea. The magnesium in Max-gut health is 98% bioavailable meaning that it is readily available for absorption and to be utilised by the horse, with any excess excreted via the urine. Supplementation of Max-gut health will help to ensure that the horse’s daily requirement is met.

Calcium is essential for skeletal strength, blood clotting, muscle contraction and energy metabolism. In a published equine research trial comparing the calcareous marine algae component of Max-gut health to calcium carbonate, the results showed a significant difference in blood markers of bone metabolism (formation and resorption) and bone density. These results suggest that the bone density support offered by supplementation may help after return to work (Nielsen et al., 2010)(2).

"A Healthy Gut Leads To A Healthy Horse"

We have been in the problem horse business for over 25 years, in that time I have researched and learned so much about horse behaviour and why it changes. 

This product for many horses has been a game changer. A healthy gut leads to a healthy horse

Who's using Max Gut-Health?


Denis Lynch Irish showjumper has his whole stable on Max Gut-Health and has seen a significant improvement in quality of coat and muscle.



Im 19 years old I have started my own stable with my girlfriend Lindsey Lebens a couple months ago. I was Belgium champion with the ponies in 2014 , European champion juniors with team Belgium in 2018, won a couple of ranking classes and many more wins in smaller classes


Max Gut-Health promotes the growth of fibre digesting bacteria..

When horses undergo a period of stress, fibre fermentation is often decreased. Therefore, promoting the growth of fibre-degrading bacteria in the gut enhances fibre fermentation and helps to maintain a healthy gut.



Max Gut-Health reduces acid accumulation in the hind-gut?

The live yeast within Max Gut-Health competes with the lactate-producing bacteria for sugars, thereby reducing acid load and helping to maintain pH within the hindgut. Maintaining a healthy gut environment optimises overall health.


How Max Gut-Health can help your horse:

- Improves feed digestibility

- Improves coat and hoof condition

- Provides a bioavailable magnesium and calcium

- Promotes good gut health during periods of stress

- Reduces lactic acid accumulation in the fore and hind gut


Signs Your Horse Has Acidosis

Signs that your horse could potentially have acidosis of the hind gut, (there could also be other physical reasons, always seek a vets advice).

1. Is your horse hot, you can’t put your leg on and you feel as though you are a passenger rather than a rider?

2. Does your horse cramp behind when jumping?

3. Are they funny about having a hind leg picked up?

4. They aren’t muscling up quite as you would expect?

5. General tightness through the body?

6. Loose droppings?

7. Suffer from tying up (Azoturia)?

8. Poor dooer (horses though can still look really well and still have a low level of acidosis of the hind gut.) Horses that are systemically challenged will take longer to come right.

9. Are they generally grumpy or grumpy when you doing their girth or grooming in that general area?

10. You have treated for ulcers with the vet and they return.

Max Gut-Health has the potential to help many of these issues (providing they are gut related and not another physical reason).


The Importance Of Good Gut Health

Horses have evolved to ingest small quantities of fibrous feeds on an almost continual basis, spending approximately 80% of their time foraging or feeding in the wild. As a result, they can efficiently digest large quantities of fibre but are less able to digest starchy concentrates. Understanding the digestive physiology of the horse helps to comprehend the myriad of health issues it is susceptible to in modern management practices.

It has been widely documented that maintaining the horse’s digestive health is an essential contributor to sustaining overall horse health, with good digestive health being linked to increased performance, behaviour and immunity. It is therefore essential to understand the fundamentals of the equine digestive tract to make more appropriate feeding and management choices.

Digestive Physiology Of The Horse

The digestive physiology of the horse differs from many other species in such a way that its gastrointestinal tract can be split into two sections. 
  1. The foregut (pre-cecal) being remarkably similar to the monogastric species’ simple stomach, like a pig or a dog. 
  1. The hind gut being comparable to that of a cows rumen relying on the symbiotic relationship with microorganisms to digest the fibre portion of the ration.

Figure 1: The difference in digestion type, size, capacity and % of gastrointestinal tract between the foregut and the hindgut in the horse. (Atlas of Topographical anatomy of the domestic animals, P. Popesko, 2008) The stomach and the hindgut have a large role in maintaining horse health: 


The Stomach

The importance of the equine stomach is often overlooked due to its small size (figure 1) and low fermentation capacity in comparison to the hindgut. However, the stomach’s upper and lower regions have an important role in equine digestion. The upper region of the stomach also known as the ‘non-glandular region’ contains a small quantity of microorganisms, initiating the fibre fermentation process when the pH is at the desired level of 5.0 – 7.0 (towards neutral).

The lower region known as the ‘glandular region’ secretes both hydrochloric acid for feed material breakdown and pepsin enzymes to start protein digestion. As the glandular region secretes acid in varying quantities throughout the day, the pH remains acidic at 2.0 – 3.0. It also has a protective mucosal layer to prevent the acidic environment from causing damage to the stomach lining. 

The pH of the two stomach regions can be maintained when the horse is able to display its natural feeding behaviour. This is due to the almost continual forage consumption both stimulating saliva production which has low levels of acid buffering activity and aiding the maintenance of a stable feed passage rate. 

Stomach Issues In Modern Feeding Practices

Issues arise in the stomach when the acidity in the upper non-glandular region drops below pH 5.0, as it is susceptible to damage due to the absence of the acid protecting mucosal lining found in the lower glandular region.

The non-glandular region can become more acidic for numerous reasons: 

  • - Low fibre diet
  • - Large concentrate meals 
  • - Insufficient fibre:concentrate ratio 
  • - Long periods of time without consuming feed
  • - Transportation/exercise/stabling stress
  • - Poor appetite/changed eating behaviour
  • - Weight loss and difficulties in maintaining normal body condition
  • - Poor coat condition
  • - Reduced performance
  • - Behaviour changes
  • - Abdominal discomfort
  • - Crib biting 

Figure 2: Possible clinical signs in horses with EGUS. A horse can have EGUS and display none of the above so should be assessed on an individual basis. (Luthersson and Nadeau, 2013). 

Maintaining a healthy stomach environment is therefore essential to help maintain horse health and reduce the occurrence of other common issues (figure 2). 

The Hindgut

As highlighted in Figure 1, digestion in the hindgut is largely microbial rather than enzymatic. This means that digestion in the hindgut is performed by billions of symbiotic bacteria which efficiently breakdown plant fibres into simpler compounds called ‘volatile fatty acids’ (VFAs) and undigested starches into lactic acid, which can then be absorbed through the gut wall as a source of energy for the horse. 

The pH of 6.5-7 in the hindgut is at the optimal level for the microorganisms to work effectively. In addition, to allow the microorganisms time to act on the fibre the passage rate of feedstuffs is much slower in the hindgut when compared to the foregut (5hrs verses 35hrs on average). 


3 Top Tips To Maintain Gastrointestinal Health

- Minimum of 1.0 – 1.5 kg of forage/100kg body weight and provide forage ad-libitum. 
- Provision of a gut health supplement to help maintain optimal pH. 
- Split concentrate meals into small meals across the day.

Hindgut Issues In Modern Feeding Practices

The provision of starch via concentrate feed is common, yet the horse’s gastrointestinal tract regularly can’t cope with the quantity provided. 

Starch is digested via the enzymatic action in the foregut, however, fast passage rate and limited digestive action means that the digestive capacity of the foregut is easily exceeded. As a result, some undigested starch can pass into the hindgut where its subsequent fermentation increases the amount of lactic acid produced (figure 3), which in turn decreases the pH and changes the type of microbes present in the hindgut. The reduction in pH from 6.5-7 to 4.0-6.0 (more acidic) in the hindgut causes some of the desirable fibre-fermenting bacteria to die and stimulates the reproduction of lactate-producing bacteria in the hindgut. This extenuates the issue as lactic acid producing bacteria proliferate in an acidic environment making it more difficult for the horse to overcome the challenge. Hindgut acidosis is linked to a variety of equine health and behaviour issues (figure 3) further highlighting the need to maintain gastrointestinal health.
