The mushroom people take to wind down in the evening.
Evening routineFor the end of the day, every day.
After dinner, or in the last cup.
No caffeineAnd not a sedative.
Nothing to wire you, and nothing that knocks you out.
What our customers take Reishi for, in their own words in the reviews below. Individual experience varies.
How to use it
Two droppers. Done.
A simple evening habit.
01
Measure 2 droppers
Two millilitres is the daily serving.
02
Add it to a warm drink, or under the tongue
A caffeine-free one: a herbal infusion, plant milk or the evening cacao. Or hold it under the tongue for several seconds, then drink some water.
03
Repeat daily
Time and consistency are the key.
When
In the evening, as a fixed part of the end of your day.
Alcohol
None. It is evaporated after the extraction.
Do not exceed the recommended daily serving.
In a warm drink
A herbal infusion, plant milk or the evening cacao.
Under the tongue
Hold it for several seconds, then drink some water.
At the end of the day
A simple, fixed part of the evening routine.
TriterpenesBeta-glucans 1,3 / 1,6
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
Structure, simplifiedTriterpenes · dissolve in alcohol
Ganoderic acids
The triterpenes of reishi: compounds characteristic of Ganoderma lucidum, and the source of its bitterness.
Why it mattersThe bitter triterpenes of reishi, and the compounds it is best known for. The bitterness is how you can tell a real extract.
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”.
Structure, simplifiedPolysaccharides · 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.
Why it mattersThe best-known compound in functional mushrooms, and the one a good extract is judged by.
In this extractNaturally present in reishi.
On recordThe standard yardstick for a mushroom extract: the higher the confirmed level, the more concentrated the extract.
These compounds are naturally present in reishi. The beta-glucan figure in the lab panel was measured on the 10:1 extract powder, not on the drops. The drawings are simplified. “Why it matters” says what a compound is or is known for, not a promised effect.
Use it regularly
The 12‑week cycle.
As with regular training or a considered diet, the key is time and consistency.
Daily serving

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
★★★★★Three months in
“I am very surprised by Solve Labs. I have tried it several times and I feel different since I started using it… you normally last 3 months.”

FAQ
Questions, answered.
Mostly to wind down at the end of the day, as part of an evening routine. It is a food supplement, not a medicine, and individual experience varies: the reviews on this page are our customers’ own accounts.
In the evening: after dinner, or in the last cup of the day. Take it at the same time every day. It contains no caffeine.
No. Ethanol is used in the extraction and is evaporated afterwards.
The capsules and the powder are the same 10:1 extract: 1,000 mg a day, as two capsules or two scoops. The drops are a 20:1 liquid extract, 2 ml a day. Choose the one you will actually take every day.
Yes, it is made for daily use. Regulars take it in cycles: twelve weeks of daily use, then two weeks off. Do not exceed the stated daily dose.
A fresh bottle at the interval you choose, at 20% off. Pause, skip a delivery or cancel at any time from your account. There is no minimum term.
It is not for children, or for use during pregnancy or breastfeeding. If you take medication or are under medical care, talk to your doctor first.
Orders are dispatched within 1–2 working days. UK standard delivery takes 3–5 working days and is free on orders over £50. Your first order has a 60-day guarantee, even opened. Delivery, returns and subscriptions are explained in full on the Help page.
Rather swallow, or stir? The same mushroom comes as capsules and as a powder.

How we did it
Where a marketplace listing hid the ingredient statement, we recovered
it from the brand’s own website — bringing 264 of 273
listings to a readable standard.
Every lab document was opened and read. Photos, badges,
spec sheets and marketing graphics did not count; broken links were graded down.
A figure was recorded only where the number sat directly against the
term it describes.
A clean ingredient statement is the seller’s own claim, recorded
as published — not independently verified here. Listings and lab documents change;
these findings describe them as of 15–16 August 2026. Prepared from a master
database of 273 listings, one row per product. Not medical advice; no statement evaluated
by the FDA or MHRA.
