Does Your Gut Supplement Cover the Whole Tract?

Most gut supplements focus on the stomach or the hindgut. Not both. Four Sixes Complete Gut Protection is built to support the entire digestive tract.

A Stressed Gut Starts a Fire

The gut is two systems. A foregut and a hindgut. Both break down under stress.

Training, hauling, feed changes, and hard feed all push the gut past what it was built to handle. Acid splashes where it does not belong. Starch spills into the hindgut. The good microbes die off and the bad ones take over.

Acid erodes the unprotected stomach lining
Bad bacteria drop the pH and crowd out the good
The gut wall weakens and toxins leak into the bloodstream

This is leaky gut, but it does not stay in the gut. Those toxins travel to the muscles, the joints, and the whole body. Four Sixes Complete Gut Protection is the only supplement built to defend both ends of the tract at once.

You Are Protecting Half of the Gut.

Most gut supplements pick a side. A buffer for the stomach. A probiotic for the hindgut. One or the other. But the gut is two systems working as one. A kitchen up front and a brewery in the back. When one suffers, the other is listening. Complete Gut Protection is the only supplement built to defend both ends of the tract at the same time.

Shop Gut Support

Pre. Pro. Post. The Complete Trifecta.

Most gut supplements pick one. Complete Gut Protection runs all three.

01

Prebiotic: The Fertilizer

Prebiotics feed the good microbes and act as decoys for the bad ones. The bad bacteria latch on and get flushed out in the manure. Fuel for the good, a trap for the bad.

02

Probiotic: The Reinforcements

Not a random tincture of strains. Acid-resistant probiotics that survive the gut, suppress the bad microbes, and let the horse's own trillions of good microbes expand back to balance.

03

Postbiotic: The Finished Tools

Postbiotics are the beneficial molecules microbes produce. Fed at research-backed levels, they cross into the bloodstream and calm inflammation far beyond the gut. In studies, adding the postbiotic alone lowered inflammation inside the joint.

04

L-Glutamine: The Fuel for the Lining

The trifecta handles the hindgut. L-Glutamine feeds and protects the stomach and small intestine lining. That is how one supplement covers the whole tract, end to end.

Early Signs of Gut Issues

Poor Recovery

Slow to bounce back after work. Times slip and you cannot figure out why.

Weight Loss

Drops condition even on good feed. The nutrients are passing through, not absorbing.

Dull Coat

Loses the shine and looks rough. When the gut struggles, it shows in the coat.

Behavioral Changes

Pins the ears or flinches when the girth tightens. Often the first sign of a stomach ulcer.
Loose Manure

Chronic loose or watery manure that will not firm up.
Poor Appetite

Leaves grain, eats slower, or walks away from the feed tub. The gut is telling you something.

Gut Testimonials

Tina L.

Had a barrel mare that got cinchy and started leaving feed. Vet found ulcers. We treated her, but they kept coming back every time we hit the road hard. Put her on Complete Gut Protection and kept her on it through haul season. No more cinchy, nice manure, and she is finishing runs strong again.

— Tina L.

Debra Jo M.

I started using the gut supplement because my gilding has water fecal syndrome, and I have tried everything possible to treat it. The gut supplement is the only thing that has helped him. I have taken him off alfalfa and orchard hay as well. I believe this product is the only supplement that has consistently helped balance his gut and given him relief.

— Debra Jo M.

Amber West

Great product that keeps all of our performance horses working at their best

— Amber West

William C.

My gelding was on omeprazole for months and the second we pulled him off, everything came right back. Our vet suggested we add a gut supplement that covers both ends. Switched to this and weaned him off the meds. He has held steady for six months now. Wish I had found it sooner.

— William C.

Tami L.

We start every horse in training on this now. Between the hauling, the hard feed, and the show schedule, they are all in the crosshairs for ulcers. Getting ahead of it has saved us money and vet visits. Feed it before you have a problem.

Frequently Asked Questions

How is Four Sixes Complete Gut Protection different from other gut supplements?

Most gut supplements pick one target. A buffer for the stomach, or a probiotic for the hindgut. One or the other. Complete Gut Protection supports the whole tract in a single formula, the foregut and the hindgut, at research-backed levels. Complete Gut Protection was formulated so you do not have to buy two or three products to cover what one horse needs.

Why does it have prebiotics, probiotics, and postbiotics?

Each one does a different job, and missing one leaves a gap. Prebiotics are the fertilizer that feeds the good microbes and act as decoys for the bad. Probiotics are acid-resistant reinforcements that suppress the bad microbes and let the horse's own good population expand. Postbiotics are the finished tools the microbes produce, and at the right levels they cross into the bloodstream and calm inflammation far beyond the gut. Most products run one. This runs all three.

What is the difference between the foregut and the hindgut?

Think of it as a kitchen and a brewery. The foregut, the stomach and small intestine, is the kitchen. It breaks down fats, proteins, and carbohydrates. The hindgut, the colon and cecum, is the brewery. It ferments forage into energy the horse runs on. The two are delicately connected. When one suffers, the other is listening. That is why a supplement has to support both.

Why does the gut affect the whole horse?

The gut is the headquarters of the immune system. When the gut wall weakens, toxins leak into the bloodstream and travel far from the gut, often landing in the joints and muscles, driving inflammation and aches. A healthy gut is not just about digestion. It shows up in recovery, in the coat, in the attitude, and in performance.

When should I start gut support?

The day your horse goes into training, not the day symptoms show up. Any horse in a real training program is in the crosshairs for ulcers. If you wait until the horse gets cinchy, drops weight, or stops recovering well, you are already behind and now you are fixing a problem instead of preventing one.
