Understanding Beta-Glucans

Beta-glucans are the one compound every Flow State product has in common, and they're a big part of why mushroom extracts build gradually rather than doing much on day one. Here's what they actually are, why they take time to work, and what makes each mushroom distinct beyond them.

What Are Beta-Glucans?

Beta-glucans are naturally occurring polysaccharides, a type of complex carbohydrate, found in the cell walls of fungi, yeast, algae, oats and a handful of other plants. Fungal beta-glucans are particularly well known for how they interact with the immune system, which is why they're widely regarded as one of the key active compounds in medicinal mushrooms.

When consumed, mushroom beta-glucans interact with immune receptors in the digestive system, supporting communication between immune cells and normal immune function. They're also increasingly researched for a broader role in gut health, healthy inflammation responses, antioxidant activity, and general wellbeing.

Why This Builds Over Time, Not Overnight

Beta-glucans don't work the way a stimulant does. There's no single dose that produces an immediate, noticeable effect. Instead, they interact with the body cumulatively, through sustained daily use, which is exactly why consistency matters more than any single serving. This is the actual mechanism behind the "give it time" advice you'll see throughout our content: it isn't a vague disclaimer, it's a direct consequence of how these compounds actually work.

Not Just Beta-Glucans

All mushrooms contain beta-glucans, but different species also carry their own distinct compounds, which is why taking more than one mushroom isn't redundant. Lion's Mane is notable for hericenones, associated with focus and mental clarity. Reishi is rich in triterpenes, associated with its traditional use for calm and stress resilience. Cordyceps is known for cordycepin, tied to its association with steady energy and stamina. Beta-glucans are the shared foundation; these are what make each mushroom worth taking for its own specific reason.

Polysaccharides vs Beta-Glucans

One of the most important things to understand when comparing mushroom supplements is the difference between "polysaccharides" and "beta-glucans." Some products advertise a high polysaccharide percentage, which can be misleading, since "polysaccharides" is a broad term that includes starches and fillers that don't come from the mushroom itself. Beta-glucans are a much more specific measurement, and one of the better indicators of actual extract potency and quality. That's why we test for beta-glucans specifically, rather than reporting a generic polysaccharide figure.

Dual Extraction and Testing

Our mushroom extracts are dual-extracted, using both hot water and alcohol, to capture as broad a range of compounds as possible. We aim for a minimum of 30% beta-glucans across our encapsulated range, and many batches test significantly higher, our most recent Lion's Mane and MyComplete batches both independently tested above 50%. Beta-glucan testing is carried out through Massey University using the Megazyme method, alongside our usual screening for heavy metals, pesticides and microbial contamination.

Transparency Matters

Rather than simply making a claim about potency, we publish our third-party test reports so you can check the actual numbers behind whichever product you're taking. Beta-glucan percentage is the specific marker that gets verified on every batch, which is what turns "trust us" into something you can actually go and look at.
