Not all mushroom supplements are the same. The difference isn't in the name on the package, but in what happens before that: the extraction method. Double extraction is the technique that determines how many active compounds actually end up in your capsule or powder.
What's inside a mushroom?
A medicinal mushroom contains two groups of active compounds that each require a different approach to be released.
The first group is beta-glucans. These are polysaccharides — complex sugar chains — that modulate the immune system and are responsible for many of the health benefits attributed to mushrooms. They dissolve in water.
The second group is triterpenes. Think of the ganoderic acids in Reishi or the betulinic acid in Chaga. These compounds have adaptogenic and anti-inflammatory properties. They are fat-soluble, and therefore don't dissolve in water.
Here lies the problem with most supplements on the market.
Single extraction: half the work
Most brands choose one extraction step: hot water. That gives you the beta-glucans. Useful, but incomplete.
A water extract of Reishi contains hardly any ganoderic acids. A water extract of Chaga misses the betulinic acid. You pay for a mushroom, but you get only part of what that mushroom has to offer.
Some brands choose only an alcohol extract. Then you flip it: the triterpenes are present, but the beta-glucans are missing.
Single extraction is a choice. Often an economic one.
Double extraction: the complete plant
In double extraction, both steps are combined. First a water extract at high temperature — for the beta-glucans. Then an alcohol extract — for the triterpenes. The two extracts are then merged into one final product.
The result is a supplement that contains the full spectrum of active compounds. That's how it works in nature too: the mushroom delivers both compounds at the same time.
Studies suggest that beta-glucans and triterpenes can work synergistically. They strengthen each other's effects, rather than operating separately.
Why fruiting bodies matter
Double extraction is valuable — but only if applied to the right raw material.
Many cheap supplements use mycelium on grain: the root-like structure of the mushroom, grown on rice or oats. The problem? Much of what you're analyzing is grain starch, not the mushroom itself.
The active compounds — beta-glucans, triterpenes — are concentrated in the fruiting body: the part of the mushroom you recognize. That's the foundation that counts.
Only fruiting bodies, combined with double extraction, deliver a product that does what it promises.
What this means per mushroom
Lion's Mane
Lion's Mane is known for its potential to stimulate NGF (Nerve Growth Factor) and BDNF — proteins that contribute to the growth and maintenance of nerve cells. The hericenones (fat-soluble) and the erinacines (water-soluble) are both needed for this effect. Without double extraction you miss one of the two.
Reishi
Reishi contains beta-glucans for immune modulation and ganoderic acids for its adaptogenic action. Studies suggest that ganoderic acids may support sleep quality through GABA pathways. A water extract alone gives you immune support, but not the relaxation.
Chaga
Chaga has the highest ORAC value of all known food sources — a measure of antioxidant activity. The betulinic acid and inotodiol compounds in Chaga are fat-soluble. A water-based supplement leaves precisely those compounds behind in the extraction tank.
How to recognize a quality extract
A few questions you can ask yourself:
Is the beta-glucan percentage listed on the package? Serious brands disclose this. A good extract typically contains at least 20–30% beta-glucans, depending on the mushroom.
Is it fruiting bodies or mycelium? This is sometimes listed in small print. "Full spectrum" sounds good, but often means: mycelium on grain.
Is it third-party tested? Independent lab analyses confirm what's actually in the product. Without that verification, claims are hard to verify.
Is the extraction method described? Transparency about the production process is a basic requirement, not an extra.
In practice
The difference between a single and a double extract isn't visible on the outside. The powder looks the same. The color is similar. The price can be close.
But in the body it works differently. A complete extract offers the full profile of active compounds. A partial extract doesn't — no matter how convincing the packaging looks.
Double extraction is not a marketing term. It's a choice in the production process that has direct consequences for the efficacy of what you take.
Conclusion
The extraction method is the foundation of every mushroom supplement. All Nooni products are made using double extraction, exclusively from 100% fruiting bodies — and are third-party tested for active compound concentrations. Discover the full range at getnooni.com.
