Meet Lion’s Mane.

Lion’s Mane (Hericium erinaceus) is grown on wood, and we use the whole fruiting body. These are the compounds it is known for, and how each one reaches the extract.

The compounds inside
  • OOOOO1,6
    Structure, simplified
    Polysaccharide · dissolves in water

    Beta-glucans 1,3 / 1,6

    Long chains of glucose that build the cell walls of the mushroom: its structural fibre. The 1,3 / 1,6 form is the one found in fungi and yeast.

    In this extractMeasured: 31.8% (ALS, accredited laboratory).

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

  • CHOHOOCH₃O
    Structure, simplified
    Aromatic compound · dissolves in alcohol

    Hericenones

    A family of compounds found in the fruiting body of Lion’s Mane, and named after it: Hericium.

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

    On recordFirst isolated from the fruiting body in 1990 by Hirokazu Kawagishi’s group in Japan. Researchers have been studying them ever since.

  • HOCHOOO
    Structure, simplified
    Aromatic compound · dissolves in alcohol

    Hericenes

    Close relatives of the hericenones: the same aromatic core, with a fatty-acid chain attached.

    In this extractCarried into the extract by the same ethanol step.

    On recordFirst described in 1994 (Arnone and colleagues, Journal of Natural Products).

Beta-glucans are the compound measured in this extract. Hericenones and hericenes are naturally present in the fruiting body. Hericium erinaceus appears in 588 papers indexed on PubMed (October 2026). The drawings are simplified.

★★★★★ Instead of caffeine

“This little mushroom really has something to it. Noticeable from the very first dose — focus, good mood, and drive. On top of that, an easy connection with people around me, more communicative — a real flow. A completely different kind of stimulation than caffeine, which I haven’t touched in over two months.”

VerifiedAllegro buyer· Powder · 2021Customer photo
★★★★★ For the study hours

“I’ve been taking it for a few days and I have to admit — it works. It gives a genuine ‘clarity of mind’ and improves concentration without any physical jitters. Great for studying.”

VerifiedAllegro buyer· Capsules · 2023Customer photo
★★★★★ Four months in

“After four months of daily use, I’m honestly thrilled. As a software developer constantly juggling complex problems, I started feeling a real difference around the third week — unlike the three other brands I tried, which didn’t quite hit the mark.”

VerifiedAmazon.co.uk buyer· Powder · 2024
★★★★★ Bought a rival to compare

“I felt compelled to write this review after buying another brand to compare against. Solve Labs is far superior, in taste and effect. I take a scoop in my coffee twice a day before I sit down to do some focused work. My only criticism: it would be better in glass rather than plastic.”

VerifiedAmazon.co.uk buyer· Powder · 2023
★★★★★ The standout

“It’s truly a standout among other brands, offering premium quality at a great price.”

Verifiedemma· solvelabs.world · 2024Customer photo
★★★★★ Doesn’t change the taste

“Fast delivery, elegant packaging, and the included scoop makes it easy. Great in all kinds of drinks — it changes the taste completely not at all! Too early to judge the rest.”

VerifiedAndrzej· solvelabs.eu · Powder · 2025Customer photo
★★★★★ Stop for two weeks

“It works. And if after a month or two you think it doesn’t, and that there’s no effect — put the supplement away for two weeks and you’ll understand that it does.”

Verifiedsolvelabs.eu customer· Capsules · 2026
★★★★★ Hands down

“I’ve been in search of the magic bullet for a long time. This product is hands down the best I have tried.”

VerifiedMeg· solvelabs.world · 2024
★★★★★ No mushroom taste

“I add three grams to my morning coffee — sometimes just to hot water, since there’s no mushroomy taste at all, only a mild coffee-earthy note. It dissolves well. I feel more focused; not caffeine energy, just a better ability to concentrate.”

VerifiedAllegro buyer· Powder · 2023Customer photo
★★★★★ The repeat customer

“I’d already used this brand’s Lion’s Mane powder — the best on the market (I tried cheaper brands and they were junk). The capsule version doesn’t disappoint either. I’m on just one a day instead of the recommended two and already see it — noticeably less brain fog.”

VerifiedAllegro buyer· Capsules · 2024Customer photo
★★★★★ Tried the others

“So far, of all the ones I’ve tried, the best Lion’s Mane on the market. It genuinely works after a few weeks of daily use in coffee. In my case, better concentration and maybe a lift in mood — subtle, but real.”

VerifiedAllegro buyer· Powder · 2020
★★★★★ Proper packaging

“Finally, a supplement in proper packaging. It works great day to day — I noticed the effect by the second week, which is why I bought the larger size. I’ll take a break as recommended to keep the results.”

VerifiedAllegro buyer· Powder · 2025
★★★★☆ The honest one

“An honest take: so far I only drink it in coffee and don’t feel a clear effect yet. It might be me, or the way I’m adding it. No complaints about the product itself, though.”

VerifiedAllegro buyer· Powder · 2024
★★★★★ One a day

“Personally I take one capsule a day and I genuinely feel it improves how my mind works — better concentration, and thoughts seem to arrive on their own. This is already my repeat order and I’ll keep buying it.”

VerifiedAllegro buyer· Capsules · 2023Customer photo
★★★★★ Fits the stack

“I really like this. I take it on an empty stomach — I used to take it with morning coffee, now with water, and it’s great. I take a stack of other supplements too, but this one is genuinely effective and not over-hyped.”

VerifiedAllegro buyer· Capsules · 2025
★★★★★ Dissolves clean

“Great product — easy to use, tasteless and dissolves well, so it mixes into any drink. It works well: lifts energy almost straight away and helps with concentration. I don’t see any downsides.”

VerifiedAllegro buyer· Powder · 2024Customer photo
★★★★★ Steady dosing

“I add one scoop to matcha or coffee. Don’t increase the dose — steady use at the recommended amount gives the better effect. It supports concentration and my day feels smoother.”

VerifiedAllegro buyer· Powder · 2023
★★★★★ Patience paid

“It takes a while, and even if some of it is placebo, I feel the results. After a few weeks I noticed a real difference in how easily I focus and think clearly. That’s exactly what I was after.”

VerifiedAllegro buyer· Powder · 2023
★★★★★ The scoop included

“Convenient box with a scoop included, and it doesn’t change the taste of my coffee. Definitely recommend if you use it regularly — far handier than the pouch format. Already on my next jar.”

VerifiedAllegro buyer· Powder · 2023
★★★★★ Sceptical at first

“Definitely recommend — it really works, though I didn’t believe it at first. What I noticed most was sharper concentration and more alertness. Already buying my second, this time the larger pack.”

VerifiedAllegro buyer· Powder · 2021
★★★★★ Week three

“I started it for mental clarity, focus and energy. It wasn’t immediate, but after about two-and-a-half to three weeks I remembered things better and my mind felt sharper. Excellent quality, easy little capsules — and for the concentration of active compound, genuinely one of the best. I take two a day.”

VerifiedAmazon.es buyer· Capsules · 2025
★★★★★ Without the nerves

“I’ve tried several Lion’s Mane brands and this one works best for me by far. It gives me clarity, keeps me focused and leaves me with plenty of physical and mental energy — without making me nervous. This is the best.”

VerifiedAmazon.es buyer· Powder · 2026
★★★★★ Fifth jar

“From my own experience I’d give it a 10. It lives up to expectations — this is the fifth jar I’ve bought.”

VerifiedAmazon.es buyer· 2026
★★★★★ The 10:1 believer

“Excellent — the 10:1 formula has few equals on the market. I’m very happy and would wholeheartedly recommend it.”

VerifiedAmazon.es buyer· Capsules · 2025
★★★★★ The demanding weeks

“The quality surprised me — really good for more energy, especially during mentally demanding stretches. This particular mushroom is working very well for me.”

VerifiedAmazon.es buyer· Capsules · 2025
★★★★★ A few weeks in

“I’ve been trying Solve Labs’ Lion’s Mane extract for a few weeks and it’s been quite positive. The first thing I noticed was a slight improvement in mental clarity — as if my mind were more awake and sharp.”

VerifiedAmazon.es buyer· Capsules · 2025
★★★★★ Heavy-information days

“After a few weeks of use, it became easier to work through a lot of information — thoughts form faster and more clearly now.”

VerifiedAmazon.es buyer· Capsules · 2025
★★★★★ Early days

“So far so good — it has a nice taste and I’m hopeful. I think you need to take it daily and consistently for two to four weeks before you really feel the effect.”

VerifiedAmazon.es buyer· Powder · 2026
★★★★☆ No fillers, noticed

“This Lion’s Mane extract has been a pleasant surprise. From the very first use I noticed more mental clarity and daytime energy. The purity is obvious — no fillers or additives, which I value enormously.”

VerifiedAmazon.es buyer· Powder · 2024
★★★★☆ Fourth order

“If you want natural energy and focus, this is the best. I’ve already bought it four times.”

VerifiedAmazon.es buyer· 2024
★★★★☆ Worth the price

“I’ve been using Lion’s Mane for a few weeks and I’m very satisfied. I take off one star for the price, which feels a little high — otherwise very good quality. Recommend.”

VerifiedAmazon.es buyer· Powder · 2025
★★★☆☆ Too short a run

“Didn’t see any difference — maybe if I’d taken it for longer, but it was only the small bag.”

VerifiedAmazon.es buyer· Powder · 2025
★★★☆☆ Still unconvinced

“Supplements are always hard to judge — do you really feel anything? I tried the capsules for a month but didn’t notice a clear difference, and the tub felt only half full.”

VerifiedAmazon.es buyer· Capsules · 2025
★★☆☆☆ Not for everyone

“The capsules are small and easy to swallow. On effectiveness, though, I noticed no improvement — I finished the pack without a clear result.”

VerifiedAmazon.es buyer· Capsules · 2025
★★★★★ The decaf pairing

“A good-quality Lion’s Mane powder. Perfect to add to my morning decaf — it gives me the extra energy I need without having to resort to caffeine, a great substitute without the jitters. Good price too.”

VerifiedAmazon.es buyer· Powder · 2025
★★★★★ Dose control

“I prefer this powder to capsules because I can control the dose. It mixes well into smoothies and into coffee, and I like the taste — slightly earthy, but not overly bitter.”

VerifiedAmazon.es buyer· Powder · 2025
★★★★★ Finely ground

“Lion’s Mane has been very effective for me at reducing brain fog and increasing focus during the day. This powder is very finely ground and has hardly any taste, so it goes into coffee easily.”

VerifiedAmazon.es buyer· Powder · 2024
★★★★★ As recommended

“Very satisfied. I started two capsules a day as recommended and, after a few days, noticed a real improvement in my concentration and mental sharpness. Easy to swallow and well dosed.”

VerifiedAmazon.es buyer· Capsules · 2025
★★★★★ Screen days

“About ten days taking these each morning and I’m already feeling the benefits — especially mental clarity and concentration. I often work long hours on a screen, and it helps.”

VerifiedAmazon.es buyer· Capsules · 2025
★★★★★ Ten out of ten

“Easy to use, and I’ve found it very useful for increasing energy and improving concentration. Top quality — for the price you can’t fault it. 10 out of 10, and I’d buy it again.”

VerifiedAmazon.es buyer· Powder · 2025
★★★★★ Label-checked

“Very good. Full fruiting bodies for this price is great. The powder is very fine, dissolves in my hot drink nicely, doesn’t overpower flavours, and tastes smoother than other Lion’s Mane powders I’ve tried. Comes with a mini scoop.”

VerifiedAmazon.es buyer· Powder · 2024
★★★★★ After long workdays

“I bought this because I often have concentration problems and mental fatigue in stressful phases, especially after long workdays. After about a week of daily use — two capsules in the morning — I started to notice a difference.”

VerifiedAmazon.es buyer· Capsules · 2025
★★★★★ Short and sure

“Good-quality packaging, great-quality product, and it works as intended. As with any supplement you know why you want it, so I’ll keep this short — recommended.”

VerifiedAmazon.es buyer· Powder · 2025
★★★★☆ Easy habit

“One month’s supply, two a day — easy to take. I feel great and would recommend them if you’re looking for more clarity and focus. A little on the expensive side, but the quality is there.”

VerifiedAmazon.es buyer· Capsules · 2024
★★★★☆ No jitters

“For me, Lion’s Mane is a natural ‘brain booster’ — a caffeine alternative without the jitters. Since taking it I’ve noticed a subtle but real difference in my mental sharpness.”

VerifiedAmazon.es buyer· Powder · 2024
★★★★☆ The staple

“I’ve been using this powder for a few weeks and it’s become a staple. The extract is potent, and the focus and mental clarity are noticeable — tasks that felt draining seem smoother now.”

VerifiedAmazon.es buyer· Powder · 2024
★★★★☆ Small but lasting

“Small package, but it contains 60 servings. The extract ratio is good and in line with the competition, so the price is competitive. Tastes a little earthy and works well in coffee.”

VerifiedAmazon.es buyer· Powder · 2024
★★★☆☆ Knows the good stuff

“This very small bag is lasting a surprising amount of time. I’ve taken Lion’s Mane for a long while and this smells like the good stuff — I mix it into my granola with no impact on the flavour.”

VerifiedAmazon.es buyer· Powder · 2025
★☆☆☆☆ The one-star

“It seems to contain some kind of sugar — quite sticky. No effect for me, and I’ve had really high quality before, so I know what to expect.”

VerifiedAmazon.es buyer· Powder · 2024
★★★★☆ The resealable pouch

“Conveniently packaged in a small resealable pouch of fine powder, with a measuring spoon included for precise dosing. As someone who’s used Lion’s Mane for several years, I appreciate it.”

VerifiedAmazon.co.uk buyer· Powder · 2024Customer photo
★★★★★ Fruiting bodies, checked

“I’ve tried a few mushroom supplements, but this one stands out with its potency and purity. It’s made from 100% fruiting bodies, and at a 10:1 extract it’s super concentrated. I’ve been adding a small scoop to my morning coffee.”

VerifiedAmazon.co.uk buyer· Powder · 2024
★★★★★ The fair-minded one

“I find it hard to rate any product which claims health benefits, because so many factors may influence the perceived benefits. Subject to that qualification: I’m aware Lion’s Mane is widely thought well of, and I’m happy to accept that view.”

VerifiedAmazon.co.uk buyer· Powder · 2024
★★★★★ Into the smoothie

“The powder is easy to mix into drinks, and I’ve been adding it to smoothies without any issues. The taste is quite mild, which makes it easy to incorporate into daily routines.”

VerifiedAmazon.co.uk buyer· Powder · 2024
★★★★☆ Honest about the mess

“The advice on the packet is to mix with coffee — that works for me: it doesn’t change the flavour, and it’s an easy way to get my dose. On the downside, it’s messy to use a powder; if you store the scoop in the bag it’s impossible to get out without powder over your fingers.”

VerifiedAmazon.co.uk buyer· Powder · 2025
★★★★★ Blended with cocoa

“I usually mix a dose with Chaga and another mushroom extract, add a teaspoon of pure cocoa powder, and blend it in cold water. This supplement is pure, with no additives, which is exactly what I look for.”

VerifiedAmazon.co.uk buyer· Powder · 2024
★★★★★ A plume of powder

“Great tasting, and dissolves easily in warm water. Yogurts also benefit. Downside: when you open the packet a plume of the powder erupts and you can be covered with the stuff. But this is a great product — I can recommend 100%.”

VerifiedAmazon.co.uk buyer· Powder · 2024Customer photo
★★★★★ No hype, just trying it

“I’ve only just started and can’t say I’ve noticed any effects — worth mentioning I’m in quite good health already, so I didn’t expect much. My brother has been taking it longer and swears by it. Price seems right for a good quality product.”

VerifiedAmazon.co.uk buyer· Powder · 2025
★★★★★ Undetectable in an omelette

“I didn’t quite like the taste on its own, but it’s undetectable if you mix it with food, like an omelette or a smoothie. It feels like good quality and came properly sealed and well-packaged.”

VerifiedAmazon.co.uk buyer· Powder · 2024
★★★★☆ Not my thing — honestly

“A really good premium product for a good price, but it’s just not my thing. I like one-a-day supplements and I find more-than-once-a-day harder to remember. I can’t find much other fault — hence the 4 out of 5.”

VerifiedAmazon.co.uk buyer· Powder · 2024
★★★★★ Week one, with tea

“After more than a week taking the powder every morning with my tea, I’m feeling awake, alert and enthusiastic in my daily tasks.”

★★★★★ Not the first time

“This is not the first time that I’ve bought it, and it is definitely worth buying.”

FAQ

Questions, answered.

Hericium erinaceus is a shaggy white mushroom that grows on hardwood, eaten and brewed in China and Japan for centuries. Ours is the fruiting body only — wood-grown, never mycelium on grain — dual extracted 10:1 in water and ethanol to 1,000 mg of extract per serving.

Two capsules with breakfast, or a 1 g scoop of the powder stirred into coffee, tea or a smoothie. There’s no loading phase and nothing to time. Follow the dosage on your jar and don’t exceed the stated daily dose.

Buyers who report noticing something mostly say it took 3–4 weeks of daily use, and many describe the third month as the point it settled in. Give it a full jar before you judge it — the 60-day guarantee exists so you can.

Read the reviews and judge for yourself.

The powder is mild and faintly earthy — in coffee, most people can’t taste it at all. The capsules are tasteless.

Three things, by three independent accredited labs: beta-D-glucan content (ALS), species identity by DNA barcoding (InventUR, University of Rzeszów) and a safety panel — heavy metals, microbiology and contaminants (GBA Polska). Testing is periodic and results relate to the tested sample.

The signed reports are published and free to download — view the latest results.

Yes — it’s caffeine-free, so it sits alongside the coffee rather than instead of it. Stirring the powder into your morning cup is the most common way buyers take it.

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.
