“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.”
Every scroll is a rep. Thousands a day, for years. Your attention has been trained, just in the wrong direction.
The average time before interrupted work was picked up again.
Mark, González & Harris, 2005 · one field study of office workersAttention is a skill. It trains back, a little more each week, when you give it the same hour, the same routine and the same three things every day.
Deep work
One task, one hour, the phone in another room. That hour is what the system is built around.
Focus is not one thing. It is wiring, signal and recovery. One product cannot do all three, so the system uses three, each at its own point in the day.
Your brain grows and maintains its nerve cells with a protein called nerve growth factor. Lion’s Mane is the most studied food source of the compounds that raise it.
Attention runs on chemical messengers and steady brain waves. Brain Tech supplies the raw material for one and supports the other, with no caffeine.
Tomorrow’s focus is built tonight. In deep, non-REM sleep the brain files what you learned and clears the day’s waste. Reishi in the evening supports the wind-down that gets you there.

Mechanisms from laboratory and early human research. Food supplements, not medicines.
Five human studies, one at a time: who was tested, the dose, how long, and what changed.
| Week | Lion’s Mane | Placebo |
|---|---|---|
| 0 | 23.9 | 23.3 |
| 8 | 25.4 | 23.4 |
| 12 | 26.4 | 23.7 |
| 16 | 27.4 | 24.0 |
| 4 weeks after stopping | 25.8 | 24.4 |
Mori et al. 2009, Phytotherapy Research: 30 adults aged 50 to 80 with mild cognitive impairment, 3 g of fruiting-body powder a day for 16 weeks, then 4 weeks without. Values read from the paper’s Figure 1. Small trial (15 per group), and the authors worked for a mushroom producer. Read the paper
The clearest results came from daily use of the fruiting body over weeks, not a one-off dose. That is how the system uses it: two scoops or two capsules every morning, for at least four weeks.
Food supplements, not medicines. Studies on Lion’s Mane are small and early; these are summaries, the papers are linked.
Each Lion’s Mane report is a PDF you can open before you buy.

Read all 253 on Trustpilot →“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…”
“I ordered again because they sharpen my focus nicely and I remember things more easily.”
“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…”
“It is the only Polish brand on the mushroom supplement market that deserves trust. I have been buying month after month, I know all their products and have tried them all…”
“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.”
“I can feel it working. The powder form suits me and it dissolves nicely in coffee… Great product!”
Reviews are the opinions of individual buyers. Trustpilot reviews are written by customers of our EU store, solvelabs.eu, about the same company and the same products; they and the Allegro reviews are translated from Polish. Figures as shown on Trustpilot, October 2026.
Jacob is the founder of Solve Labs. In 87 seconds he says what is in the Lion’s Mane extract, and why.
Translated and dubbed from Polish with AI.
None of the three is a stimulant, so nothing kicks in an hour later. What changes is the shape of your working day, one step a week: the number of focused blocks, or their length.
Two scoops of Lion’s Mane in your first coffee, or two capsules with breakfast if you would rather not taste it.
Small enough to finish on a bad day. That is the point. Most of the work this week is simply turning up.
Same length, one more block. Keep taking it every day: the human studies on Lion’s Mane gave it daily for four weeks or more, and buyers who notice it tend to say so after a few weeks, not a few hours.
Now the blocks get longer.
Month one runs out. Carry on with Lion’s Mane at £25 a month, or £20£30 a month, or £24 on Subscribe & Save, or stop. Nothing renews unless you choose it.
Most of a working morning, undisturbed.
About four hours a day is where the people who do the most deep work stop.
The ladder is Solve Labs’ own method, built from 24 published sources; no study has tested this exact sequence. Four hours: Ericsson, Krampe & Tesch-Römer, 1993.
Everyone is different. This is what the routine looks like, not a promised result.
A 42-page training plan and a one-page tracker to print and keep on your desk: the six weeks above, set out week by week, with everything around the blocks.
It comes with every order, and you can start today: download the plan · the tracker
£5£10 starts the first job: the wiring. The whole system works on all three, four weeks of each, for less than Lion’s Mane and Brain Tech cost on their own.
If it is not for you, send it back within 60 days of your first order for a full refund.
One 30 g pouch of Lion’s Mane powder, which lasts four weeks at two scoops a day, and the six-week training plan, which you can download now. Not keen on the taste of powder? Sixty capsules of the same Lion’s Mane, also four weeks, are £10. UK delivery is £4.95.
UK orders are packed within one to two working days and usually arrive three to five working days after you order. You get a tracking link by email.
Nothing, unless you choose. Lion’s Mane is £25 a month (capsules £30), or 20% less on Subscribe & Save, which you can pause or cancel any time. Or you stop there.
It is a first order for new customers, one per customer. Lion’s Mane is normally £25. We would rather you try it for a month than read about it.
Because focus is three things: the wiring of the brain, the signal that runs through it, and the sleep that files the day. Lion’s Mane, Brain Tech and Reishi each work on one of them, at a different point in the day.
One 30 g pouch of Lion’s Mane powder, one jar of Brain Tech (60 capsules) and one 30 g pouch of Reishi powder. Each lasts four weeks. Today it is £32.50 instead of £80. The capsule version (Lion’s Mane and Reishi as capsules, with Brain Tech) is £47.50 instead of £95, half price.
No. It is one order. Nothing renews and there is nothing to cancel.
Lion’s Mane: two scoops in your first coffee, or two capsules with breakfast. Brain Tech: two capsules after breakfast, with water. Reishi: two scoops in cacao, plant milk or herbal tea in the evening, or two capsules after dinner.
No. None of the three contains caffeine.
