Can Omega-3s and Flaxseed Help Sweet Itch in Horses?

By Dr Duncan Houston

A horse with sweet itch can rub out an entire mane, damage the tail, open the skin and become increasingly distressed despite fly sprays, rugs and topical treatments.

Omega-3 supplements are often promoted as a natural solution because of their potential anti-inflammatory effects. Flaxseed is the most commonly recommended option for horses, but the evidence is considerably less definitive than many supplement labels suggest.

Omega-3s may provide useful nutritional support for some affected horses. They do not stop Culicoides midges from biting, and they should not be relied upon as the main treatment for an actively itchy horse.

Quick Answer

Flaxseed and other omega-3 sources may modestly influence skin inflammation in horses, but there is currently insufficient evidence to consider them a proven treatment for sweet itch.

One very small flaxseed study found a reduced skin-test reaction after 42 days, while a larger linseed-oil study found no significant improvement in clinical itching or lesion area. Omega-3 supplementation is best considered an optional addition to strict insect control, veterinary treatment and appropriate wound care. (PMC)

What Is Sweet Itch in Horses?

Sweet itch is a form of insect bite hypersensitivity caused primarily by an allergic response to salivary proteins injected by biting midges from the genus Culicoides.

It is also known as:

• Culicoides hypersensitivity

• Insect bite hypersensitivity

• Queensland itch

• Summer eczema

• Summer dermatitis

• Kasen disease

The reaction involves immunoglobulin E, mast cells, eosinophils and other inflammatory pathways. With repeated seasonal exposure, the inflammation may become chronic and increasingly difficult to control. (Wiley Online Library)

Common signs include:

• Intense itching

• Repeated rubbing against fences, trees and stables

• Hair loss from the mane or tail

• Crusts and broken hairs

• Raw or bleeding skin

• Thickened or folded skin in chronic cases

• Restlessness or irritability

• Reduced concentration during work

• Secondary bacterial infection

• Permanent white hairs or scarring following severe damage

The distribution varies according to which insects are feeding in the area. Some horses develop lesions mainly along the mane, withers, back and tail head, while others are affected along the ventral abdominal midline, chest, face, ears or limbs. (DOI)

Why Might Omega-3s Help?

Omega-3 fatty acids become incorporated into cell membranes and can influence the production of inflammatory mediators.

The principal dietary omega-3 fatty acids are:

• Alpha-linolenic acid, or ALA, found predominantly in flaxseed, linseed oil, camelina and chia

• Eicosapentaenoic acid, or EPA, found in marine and some algae-derived oils

• Docosahexaenoic acid, or DHA, found in marine and algae-derived oils

Flaxseed provides ALA rather than substantial amounts of preformed EPA or DHA.

Horses appear capable of converting at least some ALA into longer-chain fatty acids, but direct dietary EPA and DHA are incorporated into blood and muscle more reliably than ALA from flaxseed. This does not prove that marine oil treats sweet itch more effectively. It simply means that different omega-3 products do not produce identical changes within the body. (PubMed)

The biological theory is reasonable. The clinical question is whether those changes are large enough to reduce real-life itching, self-trauma and skin lesions.

That is where the evidence becomes mixed.

What Does the Research Actually Show?

The 2002 milled-flaxseed study

The University of Guelph-associated study most commonly used to support flaxseed for sweet itch involved only six horses that had positive skin-test reactions to Culicoides extract.

The trial was:

• Double-blinded

• Placebo-controlled

• Crossover in design

• Conducted over 42-day supplementation periods

• Based primarily on reactions to intradermal allergen testing

The horses received approximately 1 pound of milled flaxseed for every 1,000 pounds of body weight each day. This equates to approximately 0.1 percent of body weight, or roughly 500 grams daily for a 500-kilogram horse.

At day 42, the Culicoides skin-test reaction was smaller while horses were receiving flaxseed than while they were receiving the bran placebo. No significant difference was found at day 21. (PMC)

What the study did not prove

The study did not demonstrate that flaxseed:

• Stopped naturally occurring sweet itch

• Prevented midges from biting

• Eliminated clinical itching

• Healed open skin lesions

• Replaced medication

• Worked in a large population of affected horses

It measured the size of an experimentally induced skin-test reaction in a very small number of horses.

One horse also responded in the opposite direction to the others, which affected some of the statistical comparisons. The result is interesting, but it should be treated as preliminary evidence rather than proof of treatment efficacy. (PMC)

The 1999 linseed-oil study

A separate double-blinded crossover trial studied 17 horses with clinical seasonal Culicoides hypersensitivity.

The horses received either:

• 200 mL of linseed oil daily, or

• 200 mL of corn oil daily

Each treatment period lasted six weeks.

The researchers measured the number of itching behaviours and the total area of skin lesions. Linseed oil did not produce a statistically significant improvement in either clinical itching or lesion area compared with corn oil, although many owners believed their horses looked better during linseed supplementation. (Wiley Online Library)

This difference between owner impression and objective measurements is important. Coat shine or general appearance may improve without the allergic disease itself being adequately controlled.

The topical omega-3 cream study

A 2019 study evaluated a topical cream containing concentrated fish oil, moisturisers and other ingredients in horses with Culicoides hypersensitivity.

The treated side developed significantly greater improvement in visible skin lesions than the untreated side. However, overall itching scores did not improve significantly, and five horses experienced adverse effects. Because the cream contained several ingredients, the result cannot be attributed solely to omega-3 fatty acids. (Wiley Online Library)

More recent skin-fatty-acid research

A more recent study in healthy adult horses found that feeding ALA-rich oils, including flaxseed oil, altered the fatty-acid composition of the skin within approximately eight weeks.

However, the study did not find meaningful differences in the measured immune and inflammatory responses between the oils, and the horses did not have active sweet itch. The results support an effect on skin fatty-acid composition, but they do not demonstrate clinical allergy relief. (OUP Academic)

What Is the Overall Evidence?

Question	Current answer
Can flaxseed alter equine skin or hair fatty-acid composition?	Yes
Can it reduce an experimental Culicoides skin-test reaction?	Possibly, based on one six-horse pilot study
Has linseed oil clearly reduced clinical itching in naturally affected horses?	No significant benefit was demonstrated in one 17-horse trial
Can topical omega-3 preparations help damaged skin?	Possibly, although itch relief appears less reliable
Does omega-3 supplementation stop insect exposure?	No
Can omega-3s replace rugs, repellents or veterinary treatment?	No
Is there a universally proven therapeutic dose for sweet itch?	No

The most accurate conclusion is:

Omega-3 supplementation may support skin health and may help some individual horses, but the evidence is inconsistent and far weaker than the evidence supporting strict insect avoidance.

The World Association for Veterinary Dermatology consensus currently identifies insect avoidance as the most effective long-term management strategy for equine insect bite hypersensitivity. (Wiley Online Library)

Is Ground Flaxseed Better Than Flaxseed Oil?

Neither form has been proven superior for sweet itch.

Ground or milled flaxseed

Ground flaxseed provides:

• ALA

• Fibre

• Protein

• Lignans

• Additional calories

The positive six-horse skin-test study used milled flaxseed, not flaxseed oil. (PMC)

Flaxseed or linseed oil

Oil provides a more concentrated fat source but does not contain the same fibre, protein or lignan components as the whole seed.

The clinical study using 200 mL of linseed oil daily did not demonstrate a significant reduction in itching or lesion area. (Wiley Online Library)

Whole unground seed

Whole seeds may not be broken down as consistently during digestion, so a ground, milled or properly processed product is generally preferred when the aim is to deliver the contained oil.

Stabilised products

Ground flaxseed contains highly unsaturated fats that are vulnerable to oxidation. Use a properly stored product, follow its storage instructions and discard anything that smells rancid, bitter or paint-like.

Adding rancid fat to an itchy horse’s ration is not a particularly glamorous nutritional breakthrough.

Are Marine or Algae Omega-3s Better?

Marine and algae-derived products can provide preformed EPA and DHA.

In equine studies, direct marine sources produced much larger increases in circulating and tissue EPA and DHA than flaxseed-derived ALA. (PubMed)

However, there is not currently strong clinical evidence showing that an oral fish-oil or algae product controls sweet itch more effectively than flaxseed.

Marine products may also create practical concerns involving:

• Palatability

• Product stability

• Cost

• Exact EPA and DHA concentration

• Contamination and quality control

• Additional calories

• Competition supplement regulations

Choose according to the horse’s complete diet and a clearly stated quantity of active fatty acids, not simply a large omega-3 claim printed on the front of the bucket.

How Much Flaxseed Should You Feed for Sweet Itch?

There is no validated therapeutic dose of flaxseed for sweet itch.

The often-cited flaxseed study used approximately:

1 pound per 1,000 pounds of body weight daily

That works out to roughly:

Horse body weight	Approximate study-equivalent amount
250 kg	250 g daily
350 kg	350 g daily
450 kg	450 g daily
500 kg	500 g daily
600 kg	600 g daily

These figures describe the experimental study. They are not a universal feeding recommendation.

That amount adds substantial fat, calories, fibre and protein to the ration. It may be inappropriate for an overweight horse, a horse on a carefully controlled weight-loss plan or one whose current feed already contains significant flaxseed or added oil. (PMC)

A safer way to trial flaxseed

Before adding it:

1. Review the complete ration. Check whether the current concentrate or balancer already contains flaxseed, linseed oil or another omega-3 source.

2. Obtain a current weight and body condition score.

3. Choose a properly processed product. Use a reputable ground, milled or stabilised flaxseed product.

4. Introduce it gradually. Increase the amount over approximately 7 to 14 days rather than suddenly adding a large serving.

5. Account for the calories. Reduce another energy source when necessary rather than simply placing more calories on top of the existing diet.

6. Monitor manure, appetite and weight.

7. Allow enough time. The small positive trial did not identify a benefit until day 42.

Starting supplementation six to eight weeks before the horse’s usual allergy season is a reasonable practical strategy if omega-3s are going to be trialled. This is an inference from the available supplementation studies, not proof that pre-season feeding will prevent sweet itch. (PMC)

Which Horses Need Extra Nutritional Caution?

Have the ration reviewed before adding a large omega-3 supplement when the horse:

• Is overweight

• Has equine metabolic syndrome

• Has a history of laminitis

• Is on a controlled calorie plan

• Has chronic diarrhoea

• Is losing weight unexpectedly

• Has liver disease

• Has a poor appetite

• Is a rapidly growing young horse

• Is already receiving several oils or supplements

• Is competing under supplement-control regulations

Flaxseed may be relatively low in sugar and starch, but it is not free of calories. A low-starch supplement can still make an overweight horse heavier if the ration is not adjusted.

What Actually Works Best for Sweet Itch?

The most effective long-term strategy is reducing the number of bites.

Medication can suppress inflammation after exposure. Omega-3s may support the skin. Neither approach is as useful as preventing the allergen from entering the skin in the first place. (Wiley Online Library)

1. Start Protection Before the Horse Begins Itching

Do not wait until the horse has rubbed out the mane.

Begin the prevention plan shortly before the local Culicoides season or as soon as midges become active.

Once the skin is inflamed and the horse has begun rubbing, the cycle becomes harder to control:

1. The insects bite.

2. The horse develops an allergic reaction.

3. The horse rubs and damages the skin barrier.

4. Damaged skin becomes more inflamed or infected.

5. The itching becomes even more intense.

Early protection is usually considerably easier than trying to rescue the skin halfway through the season.

2. Use a Properly Fitted Sweet-Itch Rug

A full-coverage rug may protect:

• The mane

• Withers

• Back

• Tail head

• Chest

• Ventral abdomen

The fabric needs to prevent small midges from reaching the skin. An ordinary loose fly sheet may not provide adequate coverage.

Check the rug every day for:

• Rubs

• Heat accumulation

• Trapped moisture

• Tears

• Midge access around the neck or abdomen

• Sores hidden underneath

In hot and humid climates, protective rugs may trap moisture and contribute to secondary skin disease, so the horse must still be inspected regularly. (Wiley Online Library)

3. Adjust Turnout During Peak Midge Activity

Culicoides activity varies by species, geography and weather, but many populations feed most actively around sunrise and sunset.

Where this pattern applies, bringing a susceptible horse into a screened stable before peak activity may reduce exposure. (AAEP Publications)

The stable must actually provide protection. A horse standing indoors beside an open, unscreened doorway may remain fully available to the local midge population.

4. Use Fans and Fine Screening

Culicoides midges are weak fliers. Strong air movement from safely positioned fans can reduce their ability to land and feed.

Fine insect screening may also help, although the mesh must be small enough to exclude midges and still permit adequate ventilation. (AAEP Publications)

Secure electrical cables and position fans so horses cannot reach them, knock them over or become entangled.

5. Apply Repellents Correctly

Use a product labelled for horses and appropriate for the insects in your region.

Repellents often fail because:

• Too little is applied

• Important body areas are missed

• The product is washed off by rain

• Sweating reduces the duration

• Reapplication occurs less often than needed

• The horse’s rug prevents correct application

• The product is used after the horse is already severely inflamed

The allergy consensus notes that repellents commonly need more frequent reapplication than owners expect, particularly in wet or humid conditions. (Wiley Online Library)

Do not apply concentrated insecticides, essential oils or dog products to raw equine skin without veterinary guidance.

6. Manage the Environment

Practical environmental measures include:

• Removing manure regularly

• Managing persistently wet areas

• Improving drainage where possible

• Keeping stable areas clean and dry

• Avoiding turnout beside known high-midge habitats where practical

• Moving the horse to a less affected paddock or property in severe cases

A change of location can make an enormous difference when local insect exposure is the dominant trigger. Unfortunately, the horse does not care that the alternative paddock is less aesthetically pleasing on Instagram.

7. Treat Damaged Skin

Once the horse has rubbed the skin open, insect prevention alone may not be enough.

Veterinary treatment may include:

• Gentle cleansing

• Topical anti-inflammatory medication

• Moisturising or barrier preparations

• Wound treatment

• Management of bacterial infection

• Short-term systemic anti-inflammatory treatment

• Pain relief when appropriate

Antibiotics should only be used when secondary bacterial infection is suspected or confirmed. They do not treat the underlying allergy.

When Are Corticosteroids Appropriate?

Systemic glucocorticoids such as prednisolone or dexamethasone may provide substantial relief in horses with severe itching and self-trauma.

They are often clinically effective, but they should be used as part of a broader plan rather than as the only seasonal control method. The allergy consensus does not recommend long-term glucocorticoids as the sole treatment for insect bite hypersensitivity. (Wiley Online Library)

Potential concerns include:

• Increased infection risk

• Delayed wound healing

• Metabolic effects

• Increased insulin concentrations or reduced insulin sensitivity

• Competition restrictions

• Possible laminitis risk in predisposed horses

The relationship between glucocorticoids and laminitis is more nuanced than saying steroids routinely cause founder. A large retrospective study did not find an overall increase in laminitis among horses receiving oral prednisolone, but age and equine metabolic syndrome increased risk. Horses with insulin dysregulation, obesity, PPID or previous laminitis therefore require individual assessment and monitoring. (PubMed)

Do Antihistamines Work?

Antihistamines are sometimes included in equine allergy treatment, but responses are inconsistent.

Current consensus evidence does not support antihistamines as reliable sole treatment for any clinical stage of insect bite hypersensitivity. They may occasionally be used as an adjunct under veterinary direction, but they should not replace insect avoidance or stronger anti-inflammatory treatment in a severely affected horse. (Wiley Online Library)

What About Allergy Testing?

Sweet itch is usually diagnosed using:

• The history

• Seasonal recurrence

• Lesion distribution

• Local insect exposure

• Exclusion of other itchy skin conditions

• Response to strict insect control

Currently available allergy blood tests and intradermal tests do not have sufficient accuracy to diagnose insect bite hypersensitivity by themselves. Unaffected horses may react to Culicoides allergens, while an affected horse may not react to every test preparation. (Wiley Online Library)

Testing may be useful in selected specialist investigations. It should not overrule a convincing clinical pattern.

What Else Can Look Like Sweet Itch?

Several conditions can cause rubbing, crusting and hair loss.

Mites and lice

External parasites may cause intense itching, particularly during colder months or in horses with heavy feathering.

Pinworms

Pinworms typically cause itching around the anus and tail head. The horse may rub the tail without having the mane and ventral abdominal lesions expected with many Culicoides reactions.

Dermatophytosis

Ringworm can cause circular or irregular areas of scaling and hair loss, although itching is often milder.

Bacterial or fungal skin disease

Secondary infection can become the main driver of itching even after the original insect exposure has been reduced.

Atopic dermatitis

Horses may react to environmental allergens such as pollens, moulds or storage mites. Atopic dermatitis can occur alongside insect bite hypersensitivity. (Wiley Online Library)

Contact irritation

Fly sprays, shampoos, detergents, rugs, topical medication and plants may cause local skin inflammation.

Onchocerciasis

Onchocerca larvae can contribute to inflammatory skin lesions and may overlap in distribution with insect bite hypersensitivity.

Photosensitisation

Sun-associated skin injury usually affects non-pigmented or lightly haired areas and may indicate plant exposure or liver disease.

Pemphigus or other immune-mediated skin disease

Widespread crusting, pain, fever or disease outside the usual seasonal distribution requires a broader investigation.

The mistake is assuming every itchy horse in summer has sweet itch. The season provides a clue, not a diagnosis.

How Worried Should You Be?

Low Risk

The horse has:

• Mild seasonal itching

• Occasional rubbing

• Small areas of broken hair

• Intact skin

• Normal appetite and behaviour

• No heat, swelling or discharge

What to do: Begin strict insect control immediately. Photograph the affected areas and reassess within several days.

Moderate Risk

The horse has:

• Repeated rubbing

• Expanding hair loss

• Crusts

• Mild open sores

• Reduced concentration or rest

• Signs returning every season

• Incomplete response to rugs or repellents

What to do: Arrange a veterinary examination within several days. Review rug coverage, repellent use, secondary infection and whether additional anti-inflammatory treatment is needed.

High Risk

The horse has:

• Raw or bleeding skin

• Severe persistent itching

• Thick discharge or foul odour

• Hot, painful or swollen skin

• Reduced appetite

• Weight loss

• Marked behavioural distress

• Eye or ear involvement

• Failure of previous treatment

What to do: Contact your veterinarian the same day. The horse may need treatment for severe allergy, pain or secondary infection.

Critical

The horse develops:

• Facial or throat swelling

• Breathing difficulty

• Collapse

• Rapidly spreading painful swelling

• High fever with depression

• Severe cellulitis

• A painful or damaged eye

• Sudden severe foot pain or signs of laminitis

• Uncontrollable self-trauma

What to do: Treat this as an emergency and seek immediate veterinary assistance.

When Is Sweet Itch an Emergency?

Sweet itch is usually a chronic seasonal condition rather than an immediate life-threatening emergency.

Urgent veterinary care is needed if the horse has:

• Difficulty breathing

• Severe facial swelling

• Collapse or profound weakness

• Fever

• Rapidly spreading hot swelling

• Deep wounds

• Uncontrolled bleeding

• Pus or foul-smelling discharge

• Severe eye swelling or a closed painful eye

• Inability to stop rubbing or striking the body

• Refusal to eat or drink

• Signs of acute laminitis

• A severe reaction following medication or insecticide application

Do not repeatedly apply stronger chemicals to severely damaged skin. A horse that looks worse after each new product may have developed contact irritation or a medication reaction on top of the original allergy.

What Should You Do Right Now?

1. Reduce exposure immediately

Move the horse into the most protected environment available. Use a correctly fitted rug, fine screening and fans where safe.

2. Examine the whole horse

Check:

• Mane

• Tail head

• Withers

• Back

• Ventral abdomen

• Chest

• Face

• Ears

• Limbs

• Beneath rugs and masks

One obvious rubbed patch may distract you from more advanced lesions hidden elsewhere.

3. Photograph and record the pattern

Take weekly photographs from the same angle and record:

• Number of rubbing episodes

• Areas affected

• Weather

• Turnout times

• Repellent applications

• Rug use

• Medication

• Diet changes

• New wounds

• Appetite and behaviour

This makes it much easier to decide whether a supplement or management change is genuinely helping.

4. Clean wounds gently

Use the wound-cleaning plan recommended by your veterinarian. Avoid harsh scrubbing, concentrated disinfectants and repeated removal of firmly attached crusts.

5. Arrange veterinary assessment when signs are more than mild

The veterinarian may need to perform:

• Skin scrapings

• Hair examination

• Cytology

• Bacterial or fungal culture

• Skin biopsy

• Parasite testing

• Evaluation for environmental or contact allergy

6. Consider omega-3s only as an adjunct

A flaxseed trial may be reasonable after the complete ration has been reviewed.

Set a realistic assessment period of approximately six to eight weeks and continue insect control throughout. Do not judge success by coat shine alone. Record itching, lesion size and self-trauma.

Common Mistakes Horse Owners Make

Waiting until the mane has already been rubbed out

Protection works best before severe inflammation and self-trauma develop.

Treating omega-3s as a cure

A supplement cannot prevent allergen exposure while midges continue biting the horse.

Copying the experimental flaxseed dose blindly

The study dose may add approximately half a kilogram of feed daily to an average horse’s ration. That requires nutritional planning.

Assuming every omega-3 product is equivalent

Flaxseed provides mainly ALA. Marine and algae products provide varying amounts of EPA and DHA. The front label may say “omega-3” while revealing very little about the actual dose.

Applying more and more fly spray to open skin

Repeated chemical exposure may cause further irritation.

Ignoring secondary infection

Once damaged skin becomes infected, itch control alone may not heal it.

Using corticosteroids without assessing metabolic risk

Steroids can be very useful, but obesity, insulin dysregulation, PPID and previous laminitis change the risk assessment.

Changing several treatments simultaneously

If the rug, repellent, supplement, topical cream and turnout routine all change on the same day, you will have no idea which intervention helped.

How Can Sweet Itch Be Prevented?

A strong seasonal prevention plan should include:

• Start protection before the usual first flare

• Use full-coverage midge-proof rugs

• Inspect the skin beneath rugs every day

• Stable or shelter the horse during peak local midge activity

• Use fans and appropriately fine screening

• Apply equine-labelled repellents consistently

• Reapply according to weather and sweating

• Maintain clean, dry stable areas

• Manage manure and wet organic material

• Treat small wounds early

• Keep a seasonal itch and treatment record

• Review the ration before the insect season

• Discuss preventive medication before severe signs begin

The horse that required substantial medication last season should not begin the next season with nothing but optimism and a half-empty fly-spray bottle.

Will a Horse With Sweet Itch Be Okay?

Most horses can be kept comfortable when exposure is reduced early and consistently.

The long-term outlook depends on:

• Severity of the allergy

• Local midge burden

• Quality of environmental control

• Speed of treatment

• Presence of infection

• Ability to use protective rugs

• Other allergic disease

• Metabolic limitations affecting medication choices

• Whether management begins before the season

Sweet itch frequently returns each year. Successful management means reducing exposure and controlling inflammation before the horse causes extensive skin damage.

Omega-3 supplementation may contribute to that plan, but it is unlikely to be the part doing the heavy lifting.

Frequently Asked Questions

How long does flaxseed take to help an itchy horse?

The small positive flaxseed study identified a difference after 42 days, not after 21 days. Allow approximately six to eight weeks before assessing a nutritional trial, while continuing proper insect control. (PMC)

Can omega-3s replace corticosteroids?

No. Omega-3s do not provide rapid or predictable control of severe allergic inflammation. A horse rubbing the skin raw may require veterinary medication while insect exposure is brought under control.

Is flaxseed oil better than ground flaxseed?

Neither has been proven superior for sweet itch. The small positive pilot used milled flaxseed, while a larger clinical trial using linseed oil found no significant improvement in itching or lesion area. (PMC)

How much flaxseed should I give my horse?

There is no established therapeutic dose for sweet itch. The published pilot used approximately 1 pound per 1,000 pounds of body weight daily, but this should not be copied without reviewing the complete ration and calorie intake.

Why is my horse still itching while wearing a fly rug?

The rug may not cover the horse adequately, midges may be entering around the neck or abdomen, the horse may be exposed when the rug is removed, or infection may now be sustaining the itch. The diagnosis may also be something other than sweet itch.

The Real Takeaway

Omega-3s are biologically plausible and may support equine skin health, but the evidence for treating sweet itch remains limited and inconsistent.

One tiny flaxseed study found a reduction in an experimentally induced skin reaction after six weeks. A larger linseed-oil study found no significant improvement in natural clinical itching or lesion area. That is not enough evidence to promise owners that flaxseed will control Culicoides hypersensitivity.

The strongest treatment remains preventing bites.

Use physical barriers, appropriate turnout management, fans, screening and repellents. Treat damaged or infected skin early. Use veterinary anti-inflammatory medication when the horse’s comfort and welfare require it.

Flaxseed can be considered as one supportive part of that plan. It should never be the plan itself.
