Flaxseed Oil for Horses and Ponies: More Than Just a Shiny Coat

Flaxseed Oil for Horses. Flaxseed oil is a natural, plant-based source of energy and one of the richest dietary sources of omega-3 ALA, containing around 50–55% omega-3 fatty acids. Adding flaxseed oil to your horse or pony’s feed is a simple way to boost omega-3 intake while providing valuable dietary fat to support healthy skin, a glossy coat and overall nutritional wellbeing. Whether you’re maintaining everyday condition or supporting a horse in work, flaxseed oil is a valuable addition to their daily feed.

Whether you have a pony enjoying life in the paddock, a hard-working sport horse or a horse that needs extra condition, the right dietary oil can offer more than just additional calories. Flaxseed oil is particularly interesting because it combines a concentrated source of energy with alpha-linolenic acid (ALA), a plant-based omega-3 fatty acid that plays a role in normal cell function and the body’s inflammatory responses.

But what makes flaxseed oil worth considering, and how does it compare with more commonly used oils such as canola?

Let’s explore the potential benefits.

KEY TAKEAWAYS

 

A natural source of plant-based omega-3

Omega-3 fatty acids are important components of a balanced diet. They contribute to cell membranes and help regulate a range of normal processes throughout the body.

Horses obtain Omega-3 ALA naturally from pasture and forage, but the amount they consume varies with the type and quality of their feed. Flaxseed oil provides a concentrated way to increase dietary ALA without relying solely on forage. Flaxseed oil is especially rich in this fatty acid, typically containing around 50–55% ALA. By comparison, canola oil generally contains around 8–12%.

That means flaxseed oil can deliver substantially more plant-based omega-3 in the same quantity of oil.

Horses can convert some ALA into longer-chain omega-3 fatty acids, including EPA and DHA, although this conversion is limited. ALA also has nutritional value in its own right, so the benefits of flaxseed oil are not dependent on complete conversion to EPA or DHA.

Why it matters: For horse owners wanting to increase their horse’s intake of plant-based omega-3, flaxseed oil offers a particularly concentrated source.

 

Skin Health and a Healthy, Glossy Coat

A smooth, glossy coat is one of the most visible signs of a well-cared-for horse. While coat condition depends on many factors, including overall nutrition, grooming, health and parasite control, dietary fats contribute essential fatty acids needed for normal skin function. Flaxseed oil can help supply these fatty acids while increasing the amount of ALA in the diet.

Research in horses has shown that the type of oil fed can influence the fatty-acid composition of the skin. In a study comparing flaxseed, canola and camelina oils, horses receiving flaxseed oil had greater EPA incorporation into their skin after 16 weeks. EPA (Eicosapentanoic acid) is an Omega-3 fatty acid involved in regulating inflammatory responses and having more of it in the skin tissue could help to influence how the skin responds to irritation and inflammation. This is especially relevant to horses whose diets are being carefully managed around exercise and recovery.

This demonstrates that flaxseed oil can influence the fatty acids present in the skin, offering an important nutritional benefit beyond simply supplying extra energy

Why it matters: Flaxseed oil provides a concentrated source of plant-based omega-3 that may support skin nutrition while contributing to the body’s normal inflammatory regulation.

 

An interesting finding for young horses in training

One of the more interesting areas of equine flaxseed oil research involves young horses beginning a training programme.

In a 2022 study published in Animals, researchers investigated the effects of oil supplementation in young horses undergoing an exercise programme. The horses received either no additional oil, crude rice bran oil or a flaxseed oil blend. The oils replaced 25% of the calories supplied by their concentrate feed, and the study ran for 60 days.

The researchers measured several indicators, including creatine kinase (CK), a blood marker that can rise following exercise and is used when assessing muscle stress or damage, and interleukin-1 beta (IL-1β), a signalling molecule involved in inflammatory responses.

The results were promising:

• A lower exercise-related CK response: In the flaxseed oil group, the rise in CK measured shortly after exercise was lower after 30 days of supplementation than at the beginning of the study.
• Changes in inflammatory markers: The study found that the increase in IL-1β associated with the training programme was more pronounced in the unsupplemented control group than in the oil-supplemented groups at the end of the trial.
• Increased circulating fatty acids: Horses receiving the flaxseed oil blend had higher blood levels of ALA and linoleic acid after 30 days.

The researchers concluded that replacing some concentrate calories with oil may have benefits for young horses in training, with the flaxseed oil blend showing potential to reduce exercise-related increases in CK.

These findings are interesting because they go beyond coat appearance and demonstrate that the choice of dietary oil may influence measurable physiological responses.

Why it matters: For young horses being introduced to work, flaxseed oil is worth considering as a source of concentrated energy and ALA within a carefully balanced feeding programme.

 

Energy for condition without adding more starch

Oil is a concentrated source of dietary energy. This can be useful for horses that need additional calories to maintain or gain condition, including hard keepers and horses in work.

The advantage of adding oil is that it supplies energy without adding the starch associated with extra grain or cereal feed. Depending on the horse’s existing ration, replacing some concentrate calories with oil can help reduce the amount of starch being fed while maintaining energy intake.

This may be useful when developing feeding programmes for horses that need a higher-fat, lower-starch approach. It is particularly relevant for some performance horses and horses whose diets need careful management because of metabolic or muscle-related concerns.

Its point of difference with other oils, is the higher amount of ALA omega-3 and health benefits supplied alongside that energy.

Why it matters: Flaxseed oil can contribute useful calories while helping increase dietary omega-3, making it an option for horses needing both energy and a more omega-3-rich fat source.

 

Skin sensitivity and seasonal itching: an area of emerging interest

Horses prone to seasonal itching and skin sensitivity can be challenging to manage. These problems often involve complex interactions between the immune system, environmental triggers, insect bites and the skin barrier.

Researchers have investigated whether increasing omega-3 intake could influence some of the responses involved.

A 2002 study involving six horses with sensitivity to Culicoides insects found that feeding extruded flaxseed was associated with a reduction in the average skin-test reaction to the insect allergen. The researchers also observed changes in fatty acids in the horses’ hair.

Why it matters: Flaxseed oil can contribute ALA to the diet of horses where skin health is a priority, but persistent itching or skin lesions should be assessed and managed with appropriate veterinary advice.

 

A useful addition to a carefully balanced diet

Horses have evolved to consume forage, and good-quality pasture or hay should remain the foundation of most feeding programmes. Additional oil is not automatically necessary for every horse but for horses that need more dietary energy, are in regular work or have a feeding programme designed around a higher fat intake, flaxseed oil can offer a useful combination of calories and plant-based omega-3.

Flaxseed Oil may also be used to replace part of a grain-based ration, rather than simply being added on top. This distinction matters because the overall diet must still provide the right balance of energy, protein, fibre, vitamins and minerals.

For horses with particular health or metabolic needs, feeding changes should be planned with a veterinarian or qualified equine nutritionist.

 

How should flaxseed oil be fed to horses and ponies?

The appropriate amount depends on the horse’s size, workload, current diet, body condition and reason for supplementation. There is no single dose that suits every horse or pony but general guidelines are:

DOSAGE:

• Minature Horses: 20-30ml/day
• Pony, Yearling: 40ml/day
• Adult Horses: 50-70ml/day
• Race Horses: 140-200ml/day

When introducing flaxseed oil:

• Start with a small amount and increase gradually to allow the horse to adjust.
• Account for the extra calories in the overall ration, especially for ponies or horses prone to weight gain.
• Keep good-quality forage and a balanced diet at the centre of the feeding programme.
• Store the oil according to the product instructions and protect it from heat, light and air.
• Seek professional advice when feeding horses with metabolic conditions, muscle disorders or other specific dietary requirements.
• Always use a feed-grade oil intended for the animal and follow the manufacturer’s feeding guidance.

 

Is flaxseed oil worth considering for your horse?

Flaxseed oil offers more than an additional source of calories. Its particularly high ALA content makes it a useful option for horse owners who want to increase omega-3 intake while supplying dietary fat.

Research into young horses in training is especially interesting, with early findings suggesting that a flaxseed oil blend may influence certain exercise-related muscle and inflammatory markers. Other research has explored skin fatty-acid changes and possible effects on allergic skin responses, although the evidence is still developing.

The strongest practical reason to choose flaxseed oil over a less expensive oil such as canola is its substantially higher concentration of plant-based omega-3 to help mediate inflammatory pathways supporting joints, coat and skin. It provides a way to make the nutritional profile of a horse’s diet more omega-3-rich without relying solely on additional grain or calories.

For horses and ponies whose feeding programme would benefit from extra dietary fat and a concentrated source of ALA, flaxseed oil is an option worth considering as part of a balanced diet.
