Bio Yeast EQ

Bio Yeast EQ™ – Advanced Yeast Probiotic for Horses

Bio Yeast EQ™ is a high-potency equine yeast probiotic designed to support hindgut balance, immune resilience, and optimal forage utilization — especially during times of digestive stress, dietary change, or antibiotic use.

This targeted formula delivers 100 billion CFUs per serving from two well-researched yeast strains: Saccharomyces cerevisiae and Saccharomyces boulardii. Together, these yeasts help stabilize the hindgut environment, support fiber-digesting microbes, and strengthen the gut’s natural protective barriers.

Unlike many bacterial probiotics, yeast-based probiotics work with the horse’s natural physiology to create the conditions needed for long-term gut health.

How Bio Yeast EQ Supports Digestive Health

The equine hindgut relies on a complex microbial ecosystem to properly digest fiber, extract nutrients, and maintain normal manure consistency. When that ecosystem is disrupted — by stress, antibiotics, illness, or feed changes — digestive efficiency and immune balance often suffer.

Bio Yeast EQ helps by:

• Supporting a balanced hindgut microbiome
• Improving fiber digestion and forage utilization
• Helping maintain normal stool quality
• Supporting a stable hindgut pH
• Promoting efficient nutrient absorption

Because yeast probiotics do not compete directly with beneficial bacteria, they act as supportive regulators, helping beneficial microbes function more effectively rather than trying to replace them.

Ideal During & After Antibiotic Use

One of the most overlooked effects of antibiotics is damage to the gut’s glycocalyx — a protective, mucus-like layer lining the intestinal wall. The glycocalyx plays a critical role in stimulating the production of IgA (Immunoglobulin A), the primary antibody responsible for defending the gut against pathogens, toxins, and opportunistic bacteria.

When glycocalyx integrity and IgA production are compromised:

• The gut becomes vulnerable to pathogenic overgrowth
• Immune signaling in the digestive tract weakens
• Beneficial microbes struggle to colonize
• Even high-quality probiotics may pass through without lasting benefit

Saccharomyces boulardii, a key strain in Bio Yeast EQ, is uniquely suited for this phase of gut repair:

• Naturally resistant to antibiotics, making it safe to use during and after antibiotic therapy
• Supports repair of the gut’s mucosal barrier, including the glycocalyx
• Encourages IgA production, strengthening gut-associated immune defenses
• Helps create an environment where beneficial bacteria can successfully re-establish and thrive

By supporting the gut lining first, Bio Yeast EQ helps prepare the digestive tract so that microbial balance can be restored on a stable foundation — rather than being washed out before it has a chance to take hold.

Why Choose a Yeast-Based Probiotic?

Yeast probiotics offer unique advantages for horses:

• They are non-colonizing but highly supportive
• They help regulate microbial activity without overstimulation
• They are especially helpful during stress, illness, travel, and dietary transitions
• They can be used alongside or prior to bacterial probiotics to improve effectiveness

This makes Bio Yeast EQ an excellent foundational tool for both digestive and immune support.
