Equine Zyme Plus - for the Digestive Health of Your Horse

Equine-Zyme Plus contains a source of live, naturally occurring micro-organisms in its unique blend - which stimulate and feed beneficial bacteria that live in your horse's intestinal tract – and contains added probiotics along with colostrum.


Equine-Zyme Plus was first formulated in 1998 for Earth Song Ranch by a Cornell educated PhD Microbiologist by the name of Dr. Wu, who owned Cenzone Tech in California. Dr. Wu recognized in the 1950s that horses needed pre/probiotics too - and if you coupled that with colostrum and beta glucan mushrooms it was an incredible health enhancing formulation for our equine friends. Dr. Wu worked for Alltech designing their probiotic and other formulas before starting his own company in California in the 1990s.


Earth Song Ranch was the first company to add colostrum to its horse products way back in 1998, and still offer it today in our Equine Zyme Plus. As someone who totally respects Dr Getty, she became an advocate of adding or providing colostrum to horses. From all her research and notes she wrote a very good article on the subject as well as having been interviewed too. Please go to these links to read more:



Equine Zyme Plus is one of the oldest - and still the best - pre/probiotic blend with added pure bovine colostrum on the market. Earth Song Ranch is the only manufacturer to couple the health enhancing immune boosting benefits of probiotics and colostrum into one product. Our formula not only has colostrum, but horse friendly added probiotics and horse friendly digestive enzymes unlike other formulations by other manufacturers. Equine Zyme Plus has stood the test of time when others have come and gone, ours has always been a top seller.

It does not need to be refrigerated, just keep out of direct sunlight and in a cool, dry, dark place! 

Each 2 ounce serving includes:

  • 20 billion live naturally occurring micro-organisms
  • 50 billion live viable yeast cells      
  • 2.5 grams of digestive enzymes including Amylase, Protease, Hemicellulase, Lipase, & Glucoamylase

Customer Testimonials

"I LOVE Equine Zyme! I have had my horses on EZ for about 2 yrs now. My chestnut was having symptoms of gastric ulcers and since the introduction of this product (along with slow feeding hay nets), she is a happy healthy horse again! I was just telling my farrier last week how amazed I am with the quality of hoof growth on all of my horses. I would highly recommend this product to any one with horses!" - Chantille C.

"I'm an Equine Sports Massage Therapist. I just wanted to take the time to say "Thank You". I have been using Equine-Zyme on my horses for about 5 Months now and they are at their best thanks to it. I'll never let another one of my horses go without it. It has totally changed the lives of my horses and any horse that I recommend it to. As a Therapist I recommend the product to every client. P.S. I even use it on my dogs and cats!" - Kristin S.

"We suspected when ulcers when we brought Remy to his new home (ours) after not a great situation. His original owner barely recognized him. He was cinchy, nervous and a bit grumpy. We tried different pre and probiotics, enzymes, etc. Equinezyme is amazing! We rotate it with Equinzyme Plus depending on the season. Katniss, our other quarter horse, is a West Nile Virus survivor rescue horse. She also has blossomed on Equinezyme and Happy Mare. They are beautiful and so amazing. Soul horses. Thanks for all you do!" - Trish G.
