Many horse owners notice visible changes within 7–14 days, especially in body condition, appetite, manure quality, weight, and coat shine. Gut X is not a short-term protocol. It is designed to be fed daily as long-term gut and nutritional support.
Gut X supplies targeted gut-support ingredients, including beta glucan and hyaluronic acid, in the functional form and amount used in Gut X. Daily feeding helps support digestive function, gut lining health, nutrient use, body condition, and overall wellness over time.
And if you don’t see the difference, you’re backed by our 90-day money-back guarantee.
Nutrition starts in the gut.
Liquid delivery makes it work.
Digestive ComfortImmune SupportBody Condition Support
Gut X is delivered in a proprietary liquid form with up to 99% availability1, 2. Powders & pellets must first break apart, hydrate, & disperse into usable surface area inside a moving gut, a slow, variable process that leaves availability as low as 2.5%3.
Gut X arrives dispersed, at the correct particle size, suspended and ready on contact, so the gut isn’t left to solve dispersion problems it was never designed to solve.

Every discipline. Every level. Real horses on Dr. Peterson’s Protocol.
Real Horses. Real Change.
The owners who watched it happen, in their own words.
Rev came in ulcer-prone and struggling to hold weight. Thirty days on one pump of Gut X a day, and coat bloom and condition are the visible signs of a gut that’s finally absorbing what it’s fed.
Day 0. Off-track and ulcer-prone, struggling to hold weight.
Day 30. One pump a day. Topline and condition back.
Through the summer she carried visible ribs and a dropped topline. A few months on Gut X and the weight (and the energy) came back, for around $30 a month.
Before. Ribs and hip showing, topline flat.
After. Weight back on, coat bright, more energy.
Shot as a 30-day challenge: same horse, same spot, a month apart. One pump of Gut X a day, and the topline and condition started coming up.
Day 1. Starting point: flat topline, dull bloom.
Day 30. Topline filling, coat coming up.
What your horse can’t absorb,
your horse can’t use.
Most supplements are powders or pellets. They have to dissolve and survive the gut before any of it counts, and most of it never does. Gut X is liquid and pre-dispersed, so it’s ready the moment it reaches the gut wall.
Oral bioavailability of administered actives. Powder/pellet figure per Du et al. (2004)1; cited in full above.
With most supplements, you pay for a full dose and your horse absorbs a fraction of it. You’re not getting what you think you’re paying for. With Gut X, what’s on the label is what reaches your horse.
Works on contact. Coats and soothes the gut lining the moment it arrives, with no breakdown step to lose along the way.
Binds the gut’s immune receptors directly, supporting a healthy immune response from where it lands.
It’s not marketing. Liquid delivery has been the standard in human medicine for decades. Gut X brings it to the barn.
Why form is the whole game.
The active ingredients aren’t the differentiator, delivery is. Here’s how liquid stacks up against the dry supplements in most feed rooms.
What’s in the jug, why it’s there, and what the science says.
Every active ingredient in Gut X is at the upper end of its peer-reviewed efficacy range5, 6, 9, 10. No undisclosed dosing. Every gram is named, sourced, and dosed for clinical effect.
Liquid SystemProprietary liquid carrier
The proprietary carrier stabilizes, suspends, and pre-disperses every active before feeding, supporting uniform dosing and up to 99%2, 7, 8 availability, while powders and pellets can assimilate as low as 2.5%1.
Beta Glucanβ-1,3 / 1,6 glucan
β-1,3 / 1,6 glucan, a soluble fiber that works on contact with the gut’s immune tissue, supporting a healthy stomach lining and immune response.2, 4, 10
Hyaluronic AcidSodium hyaluronate
A high molecular weight form of hyaluronic acid that works on contact, helping form a hydrated, protective coating across the stomach and small intestine.7, 8, 10, 11

Dr. Peterson’s two-phase protocol
Load for the first 14 days with 2 pumps a day, then settle into a once-daily maintenance pump. Two pumps a day is also recommended for stressful situations, like travel, weather changes, pasture mate changes, and show preparation.
112,000 horses. Here are a few of them.

The Veterinary Standard Behind 100X Equine
Dr. Russ Peterson, DVM, MS, DACVSMR, Cert. ISELP brings nearly five decades of equine medicine, sport horse performance, rehabilitation, nutrition, and clinical decision-making to 100X Equine.
As Chief Veterinary Officer, Dr. Peterson helps guide the clinical thinking behind every 100X Equine formula, from ingredient selection to dosing strategy to how those actives are delivered inside the horse.
Gut X reflects that standard: clinically studied beta glucan and hyaluronic acid, transparent dosing, and a proprietary liquid carrier designed to keep the actives stable, dispersed, and ready for biological contact.
How the Colic Care Coverage works.
Colic surgery can run $5,000–$20,000+. Every active subscription backs your horse with up to $20,000 in surgical reimbursement, so the worst day isn’t also a financial one.

Common questions
How do I dose Gut X?
One pump per dose, top-dressed on feed. Start with a 14-day loading phase at two pumps a day, then move to one pump for maintenance. The included calibrated pump makes every dose exact. No scooping, no guesswork.
My horse is a picky eater. Will he take it?
Gut X is a palatable liquid that coats the existing ration, so most horses accept it with no fuss. If yours is especially fussy, our equine nutritionists help you transition, included free with every order.
Can I pause, skip or cancel anytime?
Anytime. Manage everything in your account or by SMS: pause, change delivery dates, or cancel with no fees and no phone tree.
How does the $20,000 Colic Care Coverage work?
Active subscriptions enroll your horse in the $20,000 Colic Care Coverage Program, reimbursing up to $20,000 in colic-surgery costs while coverage stays active. One-time orders are not covered.
Is Gut X legal for competition?
Yes. USEF and FEI compliant. No prohibited substances, so it is cleared for horses showing under both rule sets.
How quickly can I expect to see a difference?
Many horse owners notice visible changes within 7–14 days, especially in body condition, appetite, manure quality, weight and coat shine. Gut X is designed to be fed daily as long-term support, not as a short-term protocol.
And if you do not see the difference, you are backed by our 90-day money-back guarantee.
