Horse Supplements

Great gut health is an essential factor in your horse feeling and performing their best. Our equine supplements Digestive EQ & Digestive RP are designed with prebiotics and post-biotics to support your horse's complete gut health, assisting more effective digestion and nutrient absorption, better overall health, and optimum performance. Digestive VM was created to provide a great mineral and vitamin balance for New Zealand horses. Stress Paste offers extra gut support and recovery for big days, and we are very proud to also offer Equibind and MetaboLize®. All shipping of our equine supplements is free across New Zealand.

Horse owners reviews

The consistency at the top level week in and week out have shown in my horses results since using the Poseidon products. Their recovery is so much faster and they are always fresh and ready for the next show! They have never felt better and I am eternally grateful to have their support.

Maleah Lang-McMahon, International Show jumper

Digestive EQ has been a game-changer in the way my dressage horses are performing and their overall wellbeing. I now have clients who are enjoying the same results and we are all reaping the rewards! Happy horses and happy riders!

Ashleigh Kendall, Dressage

My horses are shinier, with great topline and healthier hooves. They have energy but are less explosive - I'm absolutely rapt with their condition and calm on Digestive EQ & VM. Last winter I fed less and saw them hold great condition, and these supplements are more affordable than what I used previously, so I'm also saving on my feed bill.


Since having our horses on Digestive VM and Digestive EQ our competition and race horses have improved condition by 100% and are no longer stressed when travelling.
