Many horses are missing a nutrient that influences coat, recovery, joints and respiratory health simultaneously.

That nutrient is omega-3 — specifically EPA and DHA, the forms the body actually uses. Many horses in the UK are fed linseed, which contains omega-3 but in a form that has to be converted before it can be used. That conversion is limited. Which means the gap exists even in well-managed horses on carefully considered diets.

Why feeding linseed often doesn’t change anything

Linseed, flaxseed, and also chia seeds provide ALA, a form of omega-3. Before ALA can be used, it must be converted by the body into EPA and DHA. That conversion is limited and does not reliably produce these fatty acids in horses, regardless of how much ALA is fed.

If EPA and DHA are not increasing, the downstream effects associated with omega-3 — in joints, respiratory tissue, skin, recovery — are unlikely to change either.

The Omega-3 Check establishes whether this applies to your horse in around 90 seconds.

The Omega-3 Check — is what you're feeding actually making a difference?

A short assessment that identifies whether your horse’s current diet is likely to be supplying enough omega-3, a nutrient that influences coat, recovery, joints and respiratory health, and if not, where the gap sits.

7–8 questions. Around 90 seconds. A personalised result based on your horse’s diet and the areas you want to improve.

Omega-3 Check

What Omega-3 (DHA and EPA) do in the body

DHA and EPA are incorporated into cell membranes throughout the body. Once incorporated, they are used in processes that regulate how cells respond to stress — particularly in inflammatory signalling.

The tissues in which this is most readily observed in horses are:

  • Respiratory tissue — the subject of the clinical research on which the Synaxis Core dose is based
  • Skin and coat — which turns over relatively quickly and tends to reflect changes in fatty acid status earlier than other tissues
  • Joint fluid and surrounding tissue — where signalling processes are associated with loading and movement
  • The physiological response to repeated work — where membrane composition influences how the body manages ongoing inflammatory load

These are not separate effects. They are the same change expressed across different tissues, at different rates.

Who this is for

Most owners who come to Synaxis Core have been feeding their horse carefully — linseed, a supplement, or a combination — and want to know it’s actually making a difference.

It is particularly relevant for:

  • Horses on hay-based diets or with limited seasonal grazing — where baseline omega-3 intake from forage is already low
  • Horses in consistent work where recovery and inflammatory balance matter
  • Horses where respiratory comfort or skin condition could benefit from additional nutritional support
  • Any horse whose diet is unlikely to be meeting long-chain omega-3 requirements — which describes most horses in the UK for at least part of the year

If your horse relies heavily on hay or has restricted turnout through winter, its omega-3 status is likely lower than you think. And as conditions change through spring — more turnout, more work, more environmental load — the case for ensuring adequate EPA and DHA becomes stronger, not weaker.
