A horse's gut is the engine room of its health. When the stomach lining is irritated or the hindgut falls out of balance, the signs show up everywhere else: a hard keeper that won't bloom, a sour attitude at feeding time, edginess at shows, and performance that fades when it matters most. GastroPlex™ by MVP was built to address that whole picture at once, giving horse owners one supplement that supports the stomach and the hindgut together.

Most gut products pick a lane. GastroPlex™ combines three families of ingredients so it can work from front to back of the digestive tract. A proprietary herbal blend of papaya, fenugreek, marshmallow root, aloe, slippery elm, and deglycyrrhized licorice helps stimulate protective mucus, coat and soothe irritated tissue, and support a normal inflammatory response in the gastric system. Hydrolyzed gelatin and L-glutamine supply the building blocks the stomach lining uses to defend itself against the constant wash of gastric acid. And Levucell® SC, a clinically researched live yeast, works alongside prebiotics and probiotics to stabilize the hindgut, where fermentation and most of a horse's fiber digestion take place.
The result is a single scoop that supports healthy stomach tissue, normal digestion, and a balanced hindgut, the three jobs that usually take three different buckets.

GastroPlex™ earns its place with the horses that ask the most of their digestion. Performance and show horses face hauling, new stalls, changing feed, and the pressure of competition, all of which can upset the stomach and hindgut. Hard keepers that struggle to hold weight on a low-starch program often turn a corner once their gut is working with them instead of against them. Horses recovering from or being managed for gastric discomfort, and those on stall rest or high-starch rations, are prime candidates too. By steadying the gut, GastroPlex also helps with the quieter symptoms many owners chalk up to temperament: irritability, nervousness, and a horse that simply isn't himself.
GastroPlex™ comes in two formats so it can fit how you actually manage your horse. The pellets are the everyday foundation: for an adult horse, MVP recommends one scoop, roughly 42.5 grams, fed daily in the feed. Bucket sizes run from a 3-pound starter up to a 50-pound barn supply, so it scales from one horse to a full string. The GastroPlex paste is the travel companion, formulated for the high-stress windows that hit a horse hardest, such as hauling, show day, and competition, when you want fast, targeted support without changing the whole feeding routine. MVP rounds out the program with common-sense management: free-choice hay around the clock, plenty of fresh water, minimal high-starch feed, and reduced stress wherever possible.
The supplement has earned a loyal following among owners who manage gut-sensitive horses. "Gastroplex is my first and go-to choice for horses with gut issues," says Cindy Gobler. Carol Clark, who has fed the pellets to her horses for years, points to calmer behavior under pressure, noting they are "less nervous at shows." And for owners fighting to keep weight on, Brittanie Pinneo credits the routine for real results: "This product along with a low-starch grain has really helped our hard keeper horses bloom."

GastroPlex™ is a veterinarian-recommended equine digestive supplement from MVP (Med-Vet Pharmaceuticals). It blends herbals, amino acids, and live yeast to support healthy stomach tissue and a balanced hindgut, giving owners complete digestive support in a single product.
Yes. Gelatin, L-glutamine, and a soothing herbal blend support the stomach lining against gastric acid, while Levucell® SC yeast plus prebiotics and probiotics support the hindgut, where fiber fermentation takes place. Covering both regions is what MVP means by complete digestive support.
GastroPlex™ combines a proprietary herbal blend (papaya, fenugreek, marshmallow root, aloe, slippery elm, and deglycyrrhized licorice), hydrolyzed gelatin, L-glutamine, calcium ascorbate (vitamin C), and the clinically researched live yeast Levucell® SC, along with prebiotics and probiotics for digestive balance.
Levucell® SC is a clinically researched live yeast included in GastroPlex™ to help support the health of the hindgut. A stable, well-fed hindgut helps reduce the risk of digestive disorders and supports the fiber fermentation that powers a horse.
For an adult horse, MVP recommends one scoop (approximately 42.5 grams) of GastroPlex™ pellets daily, mixed into the feed. The pellets come in bucket sizes from 3 pounds up to 50 pounds, so the program scales from a single horse to an entire barn.
The GastroPlex™ paste is formulated for high-stress periods such as hauling, horse shows, and competition. Many owners keep the pellets as the daily foundation and reach for the paste to deliver targeted support on travel and show days.
Digestive discomfort often shows up as irritability, nervousness, or trouble holding weight. By supporting a calmer, better-functioning gut, GastroPlex™ can help horses settle and thrive. Owners have reported horses that are less nervous at shows and hard keepers that finally begin to bloom on a low-starch program paired with GastroPlex.
GastroPlex™ is made by MVP (Med-Vet Pharmaceuticals), the same company behind Eclipse PM and Exceed 6-Way. MVP focuses on horse health and nutrition supplements formulated to support performance and everyday wellness.
