Your Magic Million yearling prep is perfectly planned - but does it account for the impacts that a change in diet, work leading up to sale, transport, countless inspections and an unfamiliar environment may have?

Research shows the problems created by stress can be significant. This is where our Stress Paste feed supplement plays a role.

Stress Paste is not designed to be a calming paste. Stress Paste is designed to support your horse with nutrients and compounds that help them deal directly with the effects of stress. However, often horses will be calmer on Stress Paste because their gut is comfortable and functioning normally which helps to encourage calm yet responsive behaviour.

A lot of ‘calming pastes’ on the market contain the amino acid Tryptophan, claiming that it calms horses. Stress paste does not include tryptophan because there is no scientific evidence to support this claim.

Here’s how Stress Paste supports the horse's body:

The stomach problem

A horse’s stomach releases stomach acid 24/7. Any situation, like travel, competition or fasting prior to medical procedures such as gastroscopy, that leave a horse without access to forage for longer than 4 hours allow the stomach to empty and the gastric acid builds up! pH can drop as low as 1 and this all leaves a horse at risk of gastric ulceration. The pain of a highly acidic stomach will also often lead to behavioural changes.

Strong Buffering

Magnesium hydroxide acts as a strong buffer to assist in maintaining normal stomach pH. With a normal stomach pH your horse is able to remain comfortable and calm.


The specially selected pectin used in Stress Paste combines with the magnesium hydroxide to form an ‘alkaline slime’. This slime coats the stomach wall lining and helps to maintain normal (healthy) gut wall physiology.

Supportive Amino Acid Profile

Stress Paste contains glutamine, threonine, proline and serine. These amino acids help the stomach to produce its protective mucin and reduce a stomach's susceptibility to ‘injury’. Plus they feed the gut and accelerate gut wall recovery.

The Small Intestine problem

When heat or cold stress occurs, blood flow is redistributed in an attempt to either offload or retain heat. With this occurs a compensatory reduction of blood flow to the gut, which can damage the gut lining (also called the epithelial barrier).

This epithelial barrier damage can then lead to a leaky gut (increased intestinal permeability) and a leaky gut allows antigens, endotoxins and disease causing bacteria to leak from the gut into the body!

Psychological stresses like feed restriction and social isolation can lead to leaky gut syndrome. Research shows that when animals become psychologically stressed, the tight junctions in their gut loosen. When this happens, pathogens, toxins and bacteria can leak from the gut to the body and can cause disease and inflammation.

How Stress Paste supports the small intestine


Glutamine is a significant fuel for the intestinal epithelial cells and is crucial for correct epithelial barrier function, meaning it helps to stop the gut from leaking ‘bad stuff’ into the body when the body is under stress.

Natural Betaine

Natural betaine is an osmolyte that is used to help animals cope with heat stress and to reduce the negative impact of heat stress on intestinal permeability (less leaky gut).

The Hindgut problem

Research has shown that even events we consider ‘normal’ in a modern horse’s life, like transport, have the ability to upset a horse’s hindgut microbiome. Large stress events can cause large disturbances to the microbiome which can then result in large disturbances to their overall health.

Pre & Postbiotic

The Saccharomyces cerevisiae yeast fermentation prebiotic and postbiotic supports the hindgut microbiome under stressful conditions to help them maintain normal function.

B-Group Vitamins

Sometimes heightened stress or lengthy times without eating will result in reduced B-vitamin production in the hindgut. The B-vitamins in Stress Paste will help to maintain appetite and normal muscle energy generation and support normal nervous system function under these circumstances.

The problem: Muscles & Immune System

Exercise, travel and illness all increase a horse’s need for antioxidants like vitamin E and vitamin C to provide protection from oxidative stress. Research shows that the production of vitamin C by a horse’s liver is reduced during stressful events like transport. Meaning a horse loses full use of one of its most powerful antioxidants.

Stresses, including psychological stress, can also cause the gut to leak, putting pressure on a horse’s immune system to deal with the pathogens, toxins and bacteria leaking from the gut to the body. Antioxidants like vitamins E and C are important for proper immune function to help horses overcome these immune challenges.

Powerful Antioxidants

The combination of high doses of vitamin C and natural vitamin E provides a horse with a rapid boost to their antioxidant capacity to protect muscles and organs from increased oxidative stress and to properly support normal immune function. 

Using Stress Paste non-swabbable feed supplement

This product has a unique protective effect for the fore and hindgut and provides magnesium for normal nerve function, amino acids for gut wall health, a powerful prebiotic for gut microbiome support, betaine for hydration, B vitamins for muscle and appetite, magnesium hydroxide and pectin to help protect the stomach and Vitamins C & E for antioxidant protection.
