If a vet, trainer or barn friend has brought up your horse’s gut lining, here’s how we support it. G-Tract was built for the job, and the same colostrum and probiotics run through nearly every ImmuBiome formula. If you want the background on what the term actually means, our article on leaky gut in horses covers it.
Key points
- G-Tract supports a healthy gut lining every day, alongside good forage and your vet.
- It pairs 1,500 mg of first-day colostrum with probiotics, live yeast and 5,500 mg of prebiotics.
- Give G-Tract a couple of months before you judge it, not a week.
- Forage, water and a consistent routine still matter more, and your vet comes first.
What G-Tract can and can’t do
The gut lining is a single layer of cells that renews every few days, so it leans on consistent nutrition. G-Tract gives it daily support for normal structure and function. It can’t undo a bad hay supply, a rough haul or a medical problem, and no supplement can seal the gut or make a problem disappear. If your horse is losing weight, has ongoing loose manure or just isn’t doing well, start with your vet.
What’s in G-Tract for the gut lining
- 1,500 mg of first-day bovine colostrum. Its proteins and growth factors help maintain a healthy gut lining. Ours is human-grade, collected within the first 16 hours after calving and gently processed. More on our colostrum page.
- 3 billion CFU of probiotics. Eight named strains, the same blend found in most of our formulas.
- 25 billion CFU of live Saccharomyces yeast. One of the most studied probiotics in horses, and it works along the whole tract.
- 5,500 mg of prebiotics. These feed the good microbes. Ours come from organic Turkey Tail and Lion’s Mane mushrooms.
- At least 25% beta-glucans. These support normal immune function right where so much immune tissue sits.

Answer a few quick questions in the Formula Finder and we’ll suggest a starting point.
When owners reach for G-Tract
Most horses get by fine on good forage alone. Owners tend to add G-Tract when the load stacks up week after week:
- Hard work, especially in heat
- A busy show season with lots of hauling
- Long gaps without feed, or a feed or hay change
- A course of medication from your vet (never stop one without asking first)
How to feed it
- Mix it into damp feed. Damp feed keeps the powder from sifting to the bottom of the bucket.
- Keep it consistent. Probiotics mostly pass through, so consistent feeding beats a week here and there.
- Start ahead of busy stretches. A week or two before a big trip or show season is a good habit.
- Keep the basics in place. Hay in front of him, clean water and gradual changes do a lot of the work.
G-Tract, Immune and the rest of the line
ImmuBiome G-Tract is the one we reach for when the gut lining is the priority. It brings together colostrum, probiotics, live Saccharomyces yeast (boulardii among them) and a Turkey Tail and Lion’s Mane prebiotic blend to support a healthy stomach and hindgut lining. For a horse who’s also on the road a lot, ImmuBiome Immune uses the same colostrum, mushroom and probiotic base and leans toward normal immune function. And if he’s already on Breathe, Joint & Recovery or another of our formulas, the same probiotics and colostrum are in that tub too.

Leaky gut supplement questions
What is the best supplement for leaky gut in horses?
G-Tract is where we’d start. It brings first-day colostrum, probiotics, live yeast and Turkey Tail and Lion’s Mane prebiotics together to support a healthy gut lining. Immune is the pick when travel and seasonal change are also on your list.
Can a supplement fix leaky gut in horses?
No supplement can, and we don’t claim to. G-Tract supports the normal structure and function of the gut lining, alongside good forage, clean water and your vet’s advice.
How long should I feed a gut lining supplement before judging it?
Give it a good month or two. Keep an eye on manure, weight, coat and appetite over that time, and talk to your vet if things aren’t moving the right way.
Can I feed it with my horse’s other supplements?
Usually, yes, including our other formulas. Most of them share the same probiotic and colostrum base, so call us at 1-888-31-HORSE if you’re combining several, and run the list past your vet if your horse is on medication.
Should I stop my horse’s pain medication because of his gut?
No, not without talking to your vet. Some medications are important for your horse’s comfort, and your vet can weigh the benefits against any effect on the gut.
