Our Story

Premium equine supplements, proudly New Zealand made and owned

At Seahorse Supplements, we're dedicated to equine wellbeing and recognise the crucial role that health plays in a horse's overall happiness and longevity. The Maxia range was created to provide premium supplements supporting the overall health of New Zealand horses.

Read on to learn more about who we are and how we started.

Established in 2015

After reviewing overseas research behind the benefits of red marine algae for horses which seemed too good to ignore, we began trialing Maxia Complete on both our own horses and our friend's horses.


Within a short period of time we saw significant change in the horses, resulting in Maxia Complete becoming established as a leader in
gastric health support.

Continuing to evolve

Following the success of Maxia Complete we’ve continued to look for ways to support horse owners, this led to developing Maxia Digest, which supports the overall digestive health of your horse and Maxia Balance to deliver premium quality micronutrients.


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 supplements.
