Poseidon Animal Health

Daily Support, Complete Care Horse Supplements.

Poseidon Animal Health was Founded in 2017 by Linda Goldspink-Lord. Inspired by her personal health journey she created a range of science-backed supplements to support greater wellness in animals through improved gut health. Our family-owned business has already helped thousands of horses both here and overseas, delivering on our mission of making good gut health accessible to more animals.

World-leading gut health supplements

Why are Poseidon Animal Health’s products a staple in the diets of horses in elite eventing, high-level showing and jumping, grand prix dressage, western disciplines, racing - and even lucky geriatrics living their well earned retirement? It comes down to science.

Developed with experts, using scientific evidence

Our evidence-based horse supplements are specifically designed to support horses health, and to remove the confusion and expense of trying countless supplements. Our formulations provide a low fuss, cost effective solution, that works. They are backed by science, and trusted by equine experts internationally.

Every one of our highly respected products has been formulated in collaboration with a dedicated team of equine vets, nutritionists and microbiologists who are just as passionate as us about science-based supplements that deliver proven benefits. As new scientific research on gut health reveals new knowledge, we change with it, evolving our products to ensure they continue to lead the field.

We are 100% committed to product integrity and evidence-based, world class equine supplements that change horses lives for the better. Plus, it’s all made right here in New Zealand, with the highest quality ingredients.

The evidence is in - good gut health can change your animals' overall health dramatically. See reviews and before and afters from horse lovers.

Everything we do is driven by our passion for excellence – because we love horses too.

What does good gut health look like?

It looks like your horse enjoying the best possible health, and can lead to:

- Better weight management
- Better appetite
- Less anxiety and stress
- Healthy skin and shiny coats
- Reduction in painful digestive issues
- Pain-free movement
- Good energy levels
- A stronger immune system

The list goes on, and on, because when an animal’s gut health is at its best, the rest of the animal's systems are supported to also function properly.

Gut health has a flow-on effect to a horse's overall health, which is why it’s such a powerful thing to get right.

How we began

Wellness from within

When our Founder Linda improved her own gut health to combat a long-term health issue, she quickly saw improvements in her mood, resilience and overall wellbeing. Her journey of discovery led her to look at the benefits of good gut health in animals, and the seed of the idea for Poseidon Animal Health was planted.  

“I dream of helping every animal live a life of true health, and empowering the people who love them to help. Thanks for being part of our story, I can’t wait to see what the next chapter brings.” - Linda Goldspink-Lord.
