The Deep Work System

One focused block, every day.

The gap between deep and shallow work is measured.

One focused block a day is a habit you can build. The system is that habit, with the three products that go with it.

How it works

Three jobs. One deeper block.

Focus is wiring, signal and a proper wind-down. Pick a product to see which one it works on.

Builds the wiring.

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.

    “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. Everything is as described…”

    Trustpilot Krzysztof Baranowski · January 2025
  • ★★★★★

    “Of course the product is great. But here I value the service. From the quick handling of the order, through the very nice packaging, to the after-sales service, which matters most. You can ask, you can talk. Thank you, and I recommend it!”

    Trustpilot Bartek Nowak · January 2025
  • ★★★★★

    “Fast shipping. The products are packed perfectly, so they do not arrive battered, which often happens with supplements. With Solve Labs there are no such problems. Fairly priced. A wide choice of payment and delivery options. I will certainly be back.”

Lion’s Mane

4.8 ★★★★★3,950 ratings, all channels

  • ★★★★★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.”

    Verified Amazon.co.uk buyer · Powder · 2023
  • ★★★★★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.”

    Verified Allegro buyer · Powder · 2024

Brain Tech

4.8 ★★★★★257 verified ratings

  • ★★★★★A couple of hours

    “I like to take a tablet with breakfast. My friends and I agree that for a couple of hours it strengthens concentration and clarity of mind. I can recommend it to anyone who sometimes needs that kind of boost in their work.”

    Verified Allegro buyer · August 2022
  • ★★★★★The honest one

    “Nothing spectacular. My inner calm and concentration improved a little. The effect lasted about a week and then dropped off noticeably.”

    Verified Allegro buyer · December 2019

Reishi

4.9 ★★★★★312 verified ratings

  • ★★★★★Dissolves in coffee

    “I can feel it working. The powder form suits me and it dissolves nicely in coffee. It changes the taste of the coffee slightly, it gets a touch ‘spicy’. Great product!”

    Verified Allegro buyer · Powder · May 2023
  • ★★★★★Quality, with one gripe

    “Top-quality mushrooms, but they do not dissolve well.”
