Protocol

The Synaxis Core 90-Day Protocol

Most horses in the UK are getting some omega-3. The question is whether they're getting the forms the body actually uses — EPA and DHA — at a level that's sufficient to make a difference.

Synaxis Core provides the omega-3 molecules, DHA and EPA, directly and at a dose aligned with published veterinary clinical research.

If you’ve come here from the Omega-3 Check, the gap identified in your result has one resolution. This page sets out what it is and why it’s structured this way.

Who this is for

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

Typically:

  • You’ve adjusted feed, oils or supplements — but the outcome isn’t clear
  • Things look “not quite right” rather than obviously wrong
  • You’re not looking to add more — you want to understand what’s working and give your horse the best possible support

When Omega-3 intake isn't effective

Coat condition

Recovery

Joints

Respiratory sensitivity

Persists despite careful management

If your horse relies heavily on hay or has restricted turnout through winter, their 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.

What Omega-3 (DHA and EPA) do

DHA and EPA are incorporated into cell membranes throughout the body. Once incorporated, they influence how tissues respond to stress — particularly in inflammatory signalling.

Their effects show up where membrane function matters most — recovery, joints, respiratory function, and skin.

This is why changes don’t appear instantly — they reflect structural incorporation over time.

What the Protocol is and isn’t

This gives you an answer in 90 days.

The Synaxis Core 90 Day Protocol is a defined intervention:

  1. a biologically relevant dose of DHA and EPA,
  2. delivered consistently,
  3. over a period long enough for incorporation into tissue.

It is the minimum meaningful window in which the biology can work.

The structure reflects how fatty acids are incorporated into tissue, not how supplements are typically sold.

To understand why that structure matters, you need to start with the constraint. Read the article here.

A note on research

The formulation and dose are informed by published veterinary research.

In a randomised controlled trial, algae-derived DHA supplementation increased plasma DHA levels and was associated with measurable changes in airway inflammatory markers in horses.

It demonstrates biological effect, not a guarantee of outcome in every horse.

Synaxis Core is a nutritional supplement, not a veterinary medicine. Read the research.

What to expect over 90 days

Changes are not immediate, and not all are visible.

Synaxis Core 90 Day Protocol

At six weeks and again at the end of the protocol, we'll ask you a few short questions about what you've observed. If we haven't heard from you by week eight, we'll follow up. This isn't a review request.

It's how we build an honest picture of how the protocol performs across different horses — and how we refine how it's described.

If you complete the 90 days and see no change, we want to know that too.

What happens after 90 days

The protocol has a defined end point. So does the decision that follows.

If you've seen no change, stop. Don't continue. We'll be in touch at the end of the protocol — tell us honestly what you observed.

If you've seen benefit, the biology tells you what to do next. DHA and EPA are not stored in large reserves. If supplementation stops, the gains made over 90 days will gradually reverse. A monthly subscription maintains what the protocol established at the lowest per-bottle cost.

If you've seen benefit but want to manage cost, pausing over summer and supplementing through winter is a reasonable approach. Horses on good-quality summer grass are getting some omega-3 from forage — enough to shift the baseline, though not a direct replacement for EPA and DHA. When hay becomes the primary roughage source, the case for supplementing returns.

If you pause and restart the following autumn, treat it as a new protocol. Don't assume residual benefit carries over.

Winter supplementation: approximately October to April, depending on turnout and forage quality.

If you pause entirely and restart the following autumn, treat it as a new protocol. Don't assume residual benefit carries over.

Start the 90 Day Protocol

Supplying EPA and DHA directly, at a sufficient level, with consistent delivery over time. That is what the Synaxis Core 90 Day Protocol is designed to do.
