About us


After reviewing overseas research behind Maxia Complete, it seemed too good to ignore. So, we began trialling our premium equine digestive supplements on our own horses and our friend's.

Within a short period of time we had significant improvements in the behaviour of the horses, in particular the ones that are sensitive to the flushes in grass growth and also the horses on high grain diets, so much so that we wanted to share the opportunity for other horse owners to use Maxia Complete and enjoy the benefits we have, hence Seahorse Supplements was launched in February 2015.

Since then our gastric conditioning supplement, Maxia Complete has gone from strength to strength and is now widely used nationwide. We now also offer Maxia Digest, which supports the overall digestive health of your horse.

The feedback we receive every week about our supplements makes our job so worthwhile and it is humbling to be helping so many horses with our treatments.

Please feel free to contact us for further information.

Tracey Moir – Brand Manager & Technical Support

IMG 0712

Tracey grew up in South Westland and left school to work in the racing industry.  In her words “it took me a few years to realise that being 5'7" and unable to resist a good cream bun was not going to give me a lot of time in the saddle as an apprentice jockey” and so she headed overseas to groom in Europe for 5 years. For the last 20 years Tracey has been part of a leading NZ horse feed brand, which gave her the opportunity to work alongside and learn from leading NZ and Australian nutritionists.

With her background she has a practical perspective when it comes to both horse feed and supplements and is passionate about finding solutions to support long term healthy horses. “I can only recommend products that I 100% believe in and Seahorse Supplements belong to that group. I love watching a well conditioned, happy and healthy horse at the top of its game, regardless of discipline and can't wait to show you how our products can help support the long term health of your horses”.
