Product Overview

Supports all stages of the digestion process

Grand Digest is a comprehensive new formula designed to support the entire digestive process from the stomach, through the small intestine, and into the hindgut. Grand Digest contains a powerful combination of Toxynil Plus and Zeolites to dramatically reduce the risk of mycotoxins entering the bloodstream, and glutamine to help protect the sensitive stomach lining from the risk of gastric lesions. Once feed passes into the small intestine, where the majority of nutrient absorption occurs, Grand Digest combines Multizyme, a blend of digestive enzymes, and glutamine which supports the growth of the intestinal villi to optimize the breakdown of nutrients and to enhance their delivery into the bloodstream. Finally, as the more fibrous feed elements enter the large intestine, Grand Digest's blend of shelf stable Diamond V Yeast and Aspergillus oryzae provide an effective formula for maximising bacterial digestion, maintaining proper gut pH, and improving immune response.
  • Multizyme, a blend of digestive enzymes & glutamine, supports the breakdown of nutrients
  • Shelf-stable Diamond V Yeast & Aspergillus oryzae help maximize bacterial digestion

Rated 5 out of 5 by from I first bought this in February. My horse had colic EVERY week. I was actually considering putting him down. My vet and I had tried everything. When I started Grand Digest I was skeptical. I am thrilled to report It's been It's now been six months and NO colic!!!

Rated 5 out of 5 by from Best product yet! I came across Grand Digest while researching products that would help with a mycotoxin issue I was having with my older Belgian that caused his liver enzymes to escalate. After noticing an immediate positive result in how my Belgian seemed to be feeling, I put all three of my horses on it, one who had been having watery stools. As soon as I put this particular horse on it, his stools corrected and were completely normal. When I tested the Belgian's liver values after one month they were just slightly above normal which was a HUGE improvement. I am forever grateful for this product and will continue to feed it for as long as I have horses. It has improved the coats, feet, energy level and general well being of all three horses. The only downside is my younger and smarter horse does not like the taste and will nibble around it, but I may have found a solution to that...a little bit of molasses in water squirted on the bottom of the feed bowl. I highly recommend this product. I could not be happier with it, unless maybe if it were pelleted.

Rated 4 out of 5 by from Good price, not yet sure on effectiveness I bought this along with GUT to see if I could get the same results for my ulcer rpone rescue as I did with SmartGut Ultra with some savings as the SmartGut is so $$$. 2 months in, I cannot yet tell, and it is winter in New England, so my guy is old & uncomfortable anyway. Will update as we move into spring as to how he feels and what I think about the product. I like the ingredients and think the price is right.

Rated 5 out of 5 by from Great Product, My horse has been on this for 2 weeks now. His gut sounds have decreased and his manure has firmed up. He has been having bouts of diareaha for over 2 months and this is helping. I hope to see more results the longer he's on it. Also he loves the taste!

Rated 5 out of 5 by from One of the best I tried everything for an older thoroughbred with loose stools. This works! You may need to adjust the dose as needed, but it is the only digestive supplement I have found that truly works.
