Ganoderma lucidum

Meet Reishi.

For more than 2,000 years, in Asian tradition, Reishi (Ganoderma lucidum) has been number one among the mushrooms used at the end of the day. Today it is a simple, fixed part of the evening routine for anyone who runs at full speed.

The compounds inside
  • HOOOCOOH
    Structure, simplified
    Triterpenes · dissolve in alcohol

    Ganoderic acids

    The triterpenes of reishi: compounds characteristic of Ganoderma lucidum, and the source of its bitterness.

    In this extractThey do not dissolve in water. That is why the extract is made twice: hot water, then ethanol.

    On recordGanoderic acids A and B were first isolated from reishi in 1982 (Kubota and colleagues, Helvetica Chimica Acta), and described as “bitter triterpenes”.

  • OOOOO1,6
    Structure, simplified
    Polysaccharides · dissolve in water

    Beta-glucans 1,3 / 1,6

    Long chains of glucose, naturally present in the cell walls of the fruiting bodies. A marker of the quality and purity of an extract.

    In this extractMeasured: 52.0% (ALS, accredited laboratory).

    On recordThe standard yardstick for a mushroom extract: the higher the confirmed level, the more concentrated the extract.

Beta-glucans are the compound measured in the 10:1 extract. Ganoderic acids are naturally present in reishi. Ganoderma lucidum appears in 2,915 papers indexed on PubMed (October 2026). The drawings are simplified.

VerifiedGregor· solvelabs.world · 2024
★★★★★ The best extract I’ve tried

“I have tried many brands and these are definitely the best extract powder there is. I can definitely feel the difference. Highly recommend if you are looking for good quality extracts.”

VerifiedAleksandra· solvelabs.world · 2024
★★★★★ Against the 14:1

“Great product, made in exceptional quality, taste great. Compared to its biggest competition on the UK market, where the ratio is 14:1, it’s much more noticeable in effects since I started taking it. Recommended 100%.”

VerifiedSalomea· solvelabs.world · 2024
★★★★★ Fruiting body, checked

“The fact that the extraction is solely from the fruiting body of the mushroom makes its effectiveness more intense. I investigated this matter and this is the reality. It is not a cheap product…”

VerifiedArtur M. N.· solvelabs.world · 2024
★★★★☆ The label-reader

“It is a 10:1 extract, which means that it was obtained from a larger amount of Reishi mushrooms, which increases the potency.”

VerifiedKarl· solvelabs.world · 2024

FAQ

Questions, answered.

Closing the day. Reishi is the evening tonic — taken after dinner, in capsules or stirred into cacao, to give a long day a full stop. It is the mushroom the East has reached for at the end of the day for two thousand years, and the one our customers keep by the kettle.

People whose days don’t switch off when the laptop does. Founders, nurses, new parents, night shifts — and anyone who looks after body and mind together and plans to still be doing this at eighty.

Ganoderma lucidum is a hard, lacquered, fan-shaped mushroom that grows on hardwood — lingzhi in China, reishi in Japan. It is far too woody to eat, so it has always been taken as an extract. Ours is the fruiting body only, wood-grown, extracted twice in water and ethanol and concentrated 10:1 to 1,000 mg per serving.

Two capsules after your evening meal, or two 500 mg scoops of the powder (1 g) in hot cacao, tea or warm milk. Drops: 2 ml under the tongue. Same time every evening. Follow the dosage on your jar and don’t exceed the stated daily dose.

Reishi is the slowest-burning mushroom in the range and the one people judge too early. Buyers who report noticing something mostly say it took a few weeks of nightly use; regulars talk in months. Give it a full jar before you judge it — the 60-day guarantee exists so you can.

Because it is real. The bitterness is the triterpene fraction, which only comes out in the ethanol pass. A reishi extract that tastes of nothing is usually mostly grain. If you would rather not taste it, the capsules skip it entirely.

Reishi holds two quite different fractions: water-soluble beta-glucans and ethanol-soluble triterpenes. Water alone leaves the second behind, so the extract is drawn in both and recombined at 10:1.

Same extract, three ways. Capsules if you want no taste and no measuring. Powder if you want the ritual — it is made for cacao. Drops if you want it under the tongue in seconds. The daily serving is the same.

Three things, at three laboratories. Species identity by DNA barcoding at InventUR, University of Rzeszów: 100% Ganoderma lucidum, July 2024. Beta-glucans in the 10:1 extract at ALS: 52.0%, December 2022. Heavy metals, microbiology and contaminants at GBA Polska: lot GS241204, March 2025, all within limits. Every report is published in full: open them here.

The 10:1 extract measured 52.0% beta-glucans, 52.8% on a dry-matter basis, in an accredited assay by ALS in December 2022 using the Megazyme mushroom and yeast method. That is a measured figure for beta-glucans, not a “polysaccharide” number, which also counts starch. Open the report.

Yes, it is made for daily use. Regulars run it in cycles: twelve weeks of daily use, then two weeks off before the next. Do not exceed the stated daily dose.

Sixty capsules last 30 days at two a day. A 60 ml bottle of drops lasts 30 days at 2 ml a day. A 100 g jar of powder lasts a little over three months at 1 g a day.

A fresh jar every 30 days at 20% off, with free UK delivery. Pause, skip a delivery or cancel any time from your account — no minimum term, no questions.

Try it at home for up to 60 days. If it isn’t for you, send it back — even opened — and we’ll refund the jar.

If you’re pregnant or breastfeeding, taking prescription medication, or have a mushroom allergy, talk to your doctor before starting any supplement. Food supplement — keep out of reach of young children.

Orders dispatch within 1–2 working days. UK delivery is free on orders over £50 — and always free on subscription.

Rather not stir? The same mushroom comes as capsules and as drops.
