What is Beta Glucan

Your immune system is built to learn.

Immune intelligence starts at the cellular level, where BWH-85® Beta Glucan works with the innate immune system to build greater adaptability and readiness over time.

Why immune intelligence matters.

Age with resilience

Support immune function and physiological stability as the body changes over time.

Maintain balance

Help maintain healthy, appropriately regulated inflammatory activity.

Respond with resilience

Stay better equipped during periods of physical and physiological stress.

Recover and restore

Support the processes involved in recovery and tissue repair.

Stay adaptable

Support an immune system capable of adjusting to the challenges it encounters.

Your immune system helps you respond to challenges, recover from stress, maintain balance, and stay resilient over time, making immune intelligence essential to both everyday health and healthy aging.

Your immune system is built to recognize, learn, and adapt.

Your innate immune system is constantly scanning for what matters. When it recognizes certain biological patterns, it can adapt in ways that leave immune cells better prepared for future challenges.

That process is known as trained immunity.

BWH-85® Beta Glucan works with this biology at the cellular level, helping the innate immune system become more responsive, coordinated, and prepared over time.

That is immune intelligence.

What is beta glucan?

Beta Glucan is the most studied, natural immune system supplement in the world! It is a naturally occurring polysaccharide found in sources including yeast, fungi, and grains. But not all beta glucans are the same. The source, structure, and purity can differ significantly, which influences how they interact with the immune system.

BWH-85® is an insoluble beta-1,3/1,6-glucan derived from baker’s yeast (Saccharomyces cerevisiae) and standardized to greater than 85% beta glucan.

The beta-1,3/1,6 structure and ≥85% purity of BWH-85® is recognized by key receptors on innate immune cells, supporting reliable recognition and a more consistent biological response.

How BWH-85® works in the body

BWH-85® Beta Glucan is recognized by pattern-recognition receptors on innate immune cells, including Dectin-1 and Complement Receptor 3 (CR3).

From there, a series of coordinated changes takes place that helps explain the biology behind trained immunity.

The immune system recognizes something meaningful.
BWH-85® is identified by receptors on innate immune cells including neutrophils, monocytes, macrophages, and dendritic cells. That recognition begins a cascade of cellular events associated with trained immunity.

Immune cells become more capable of working together.
Receptor engagement influences immune-cell activity and communication, including coordination between innate and adaptive immunity, downstream activity involving natural killer cells, and movement of immune cells to where they are needed.

Cells change how they function.
Research shows that beta-glucan recognition can influence cellular metabolism and intracellular pathways involved in immune coordination and balanced inflammatory activity. These changes help immune cells adapt how they generate energy and respond to future challenges.

The immune system carries the lesson forward.
Repeated exposure to recognizable beta glucan can support functional training of innate immune cells. This is trained immunity—changes in cellular function and gene expression that can leave the immune system better prepared for future challenges, including ones it has not encountered before.

Healthy aging starts with immune intelligence.

Healthy aging depends on how well the body can adapt, recover, regulate inflammation, repair, and maintain balance over time.

BWH-85 is shown to impact biological age across seven systems: inflammation, blood, immune, musculoskeletal, liver, metabolic and brain

In a 12-week TruDiagnostic study, BWH-85® was associated with measurable changes in biological age across seven systems.

What sets BWH-85® apart

Not every beta glucan has the same source, structure, purity, or consistency. BWH-85® is produced around the specific characteristics that matter for reliable recognition by the innate immune system.

Purity matters

Purity directly affects how well beta glucan works. Even a small reduction in purity can cause a much larger drop in biological activity, which is why BWH-85® is standardized to a minimum 85% purity for consistent, reliable results.
