We take an evidence-based approach to equine health, using ingredients that are scientifically backed for their effectiveness.

The horse's digestive tract is very different from other mammals due to the fact that it digests parts of its feed with enzymes first in the foregut and then ferments in the hindgut.

EGUS Equine gastric ulcer syndrome is diagnosed as either
Equine Squamous Gastric Disease (ESGD) or Equine Glandular Gastric Disease (EGGD)

Algae is a rich source of various minerals, including organic calcium which buffers excess stomach acid in horses.

Huge Improvements!
"Maxia Digest was a huge turning point for my hot, sensitive, ulcer prone mare. I have now got a rideable, sensible horse who reacts well to stress and grass flushes."
Dr. Dawne Nairn DVM
Maxia Digest
"I started using Maxia Digest on my 8 year old Dutch Warmblood. As an equine veterinarian, I am always a sceptic. After the first two weeks, I had to admit that something was quite different. My horse was settled. He had a better work ethic and we didn't have so many up and down days. The teamwork began to come through. I have scoped my horse in the past and found ulcers. I have treated him with Omeprazole for ulcers. Since starting Maxia Digest, I have had a happier horse. I will often ask clients what supplements they are using. Maxia Digest is a good complement to standard ulcer treatments. It will always be a staple in my feed room".

Love your product!
Maxia Complete has really helped Boy after he finished his ulcer course. He’s been his amazing calm self since being on it which tells me his ulcers have stayed away. I was recommended to try this to keep Boy’s stomach healthy and after talking to Hadley from Seahorse Supplements about how it works by buffering the acid, I know how much it is helping him. He has it every day and he’s looking fantastic!"
