FAQ's

What makes Four Sixes Complete Gut Protection different as an equine gut health supplement?

It supports the stomach and the hindgut in one formula. The stomach is where acid breaks down feed. The hindgut is where microbes ferment forage into energy. Stress hits both, and most gut supplements only support one.

Complete Gut Protection was developed with the Four Sixes Ranch, leading equine veterinarians, and PhD equine nutritionists. It combines research-backed prebiotics, probiotics, a postbiotic, L-glutamine, and oat beta glucan to support the entire tract, from the stomach lining to the hindgut. That makes it a fit for stressful stretches like hauling, feed changes, and courses of antibiotics or NSAIDs.

What is the difference between a prebiotic, probiotic, and postbiotic?

Prebiotics feed the good microbes. Probiotics add more of them. Postbiotics are the beneficial compounds those microbes produce.

Prebiotics are fibers that feed the beneficial microbes in the horse’s gut. In this formula, they come from oat beta glucan and yeast extract.

Probiotics are live, beneficial microorganisms, listed on the label in CFUs. This formula provides Lactobacillus rhamnosus, Bifidobacterium longum, and Saccharomyces cerevisiae boulardii CNCM I-1079 to support digestion and a normal gut immune response.

Postbiotics are the end products of microbial fermentation. Listed on the label as Saccharomyces cerevisiae Fermentation Product, this ingredient from Diamond V has extensive research supporting digestion, joint health, and muscle health.

How do I know if my horse needs gut health support?

Nearly every working horse can benefit, because training, hauling, and routine changes all put stress on the gut. Common times to feed it include:

✓ Training, hauling, and horse shows
✓ Feed changes, weaning, or a move to a new barn
✓ Layup or stall rest
✓ Senior horses
✓ Courses of antibiotics or NSAIDs

Is this a replacement for omeprazole?

No. Omeprazole is a treatment that shuts down stomach acid while your horse is on it. We recommend feeding Complete Gut Protection during treatment and after, because many horses struggle with acid rebound once omeprazole stops, which can lead to recurring ulcers. Complete Gut Protection supports the gut through that shift, with L-glutamine and oat beta glucan for the stomach lining and prebiotics, probiotics, and a postbiotic to keep the hindgut balanced.

How many probiotics are in each scoop, and do they survive?

Each 30 g scoop provides 30 billion CFU. That is 10 billion each of S. boulardii CNCM I-1079, Lactobacillus reuteri, and Bifidobacterium longum, all listed on the label. S. boulardii is a yeast, so it holds up to stomach acid and antibiotics.

What do oat beta glucan and L-glutamine do?

Oat beta glucan is a prebiotic fiber that supports a healthy stomach lining. L-glutamine is an amino acid that fuels the cells lining the stomach and small intestine. Together they support the gut lining through training, hauling, and routine changes.

How soon will I see a difference?

The gut takes about seven days to adjust to any new feed or supplement. Give it about a month of daily feeding. Many owners notice changes sooner.

Customer photo review of Equine Complete Gut Protection

My mare didn’t show the “classic” Ulcer symptoms, but had some mild things I kept under surveillance. Based on the way she plays, rides and can now urinate without the constant stretching, I’d say she’s feeling a lot better.

This is my 3year old reining prospect. He is in Training with Poplin Performance Horses . I put him on this after going to run for a million and talking to the 6666 team . Tebow has taken on a shine and is looking and performing top notch !

Equine Complete Gut Protection

MY HORSES SEEM TO BE DOING VERY WELL ON̈ THIS . WITH TWO SENIOR HORSES ON MEDICATION THEY BOTH HAVE NOT HAD ANY BACK UPS YET?

Equine Complete Gut Protection

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 give him relief.

Equine Complete Gut Protection

The product has been very helpful for my horses. My gilding has WFS and the gut health has been extremely helpful. My mare has a tendency to colic. So far, since starting the product, she has not culicid. My only disappointment is the 10% discount on my first order was not applied and I even signed up for automatic shipments.

Equine Complete Gut Protection

Store owner replied: Hi Diane! Thank you so much for your review. If you signed up for automatic shipments a 15% discounted is included in the product price. Sorry for any confusion.

I love all 6666’s supplements! Horses love it and I love that their supplements are loaded with so much in such a small dose. Makes it easy to give at anytime!

Have old gelding that had trouble with the black , tarry stool from malabsorption issues of the elderly. Started him on 6666 Gut Protection and it cleared up within 2 weeks. Very happy with results.
