If you're looking to improve your animal’s digestion, immunity, and overall health, Brewer’s Yeast is one of the most underrated but powerful natural supplements out there. At Trisana Nutrition, we include 100% pure Brewer’s Yeast in our lineup because of its proven ability to boost gut health, a foundation for long-term wellness in both dogs and horses.

What is Brewer’s Yeast?

Brewer’s Yeast is a nutrient-dense byproduct of beer brewing that’s rich in B vitamins, amino acids, and trace minerals. But don’t worry — it doesn’t contain any alcohol or hops, making it completely safe (and beneficial) for animal use.

Why Gut Health Matters

The gut is often referred to as the “second brain” for a reason. A healthy gut supports not just digestion, but also immunity, mood, energy levels, coat health, and weight stability. Whether you're dealing with a dog that has chronic gas, bloating, soft stools, or a horse that struggles with stress-induced digestive upset, supporting the microbiome can make all the difference.

Key Benefits of Brewer’s Yeast for Dogs

✔️ Supports Digestive Health:

Brewer’s Yeast acts as a natural probiotic for dogs. It boosts the gut microbiome, increasing the absorption of nutrients and improving digestion.

✔️ Reduces Gas, Bloating & Loose Stool:

Perfect for dogs with sensitive stomachs, chronic farting, or irregular bowel movements. It helps regulate gut function and ease digestive distress.

✔️ Boosts Immunity & Skin Health:

Brewer’s Yeast is rich in antioxidants and B vitamins that support a strong immune system and promote healthier skin and shinier coats.

✔️ Supports Blood Sugar & Insulin Sensitivity:

Naturally rich in glucose tolerance factors (GTF), Brewer’s Yeast may help regulate blood sugar and support dogs with insulin resistance or early-stage canine diabetes.

Key Benefits of Brewer’s Yeast for Horses

✔️ Improves Feed Efficiency:

Brewer’s Yeast helps increase nutrient absorption, allowing horses to get more out of every meal. This is particularly useful for hard keepers or horses recovering from illness.

✔️ Supports Digestive Balance During Stress:

Whether it’s travel, competition, or changing hay, horses often experience stress-related digestive issues. Brewer’s Yeast can help stabilize the gut flora, easing loose stool, colic risk, and appetite loss.

✔️ Prebiotic Power:

Often used alongside Trisana’s other equine supplements, Brewer’s Yeast is an ideal addition to support your horse’s overall digestive performance and energy levels.
