Lion’s Mane, honestly.

The shaggy white mushroom inside every LxCortex ritual — what it is, why we use the fruiting body, and how to read the science without the hype.

01 — The mushroom

What is Lion’s Mane?

Lion’s Mane (Hericium erinaceus) is an edible mushroom that grows in cascading white spines rather than a cap and stem — it really does look like a small, shaggy mane. It has been eaten and brewed across East Asia for centuries, prized as much for its delicate, seafood-like flavour as for its place in the kitchen and the apothecary.

In the wild it grows on old hardwoods — oak, beech, walnut — appearing in late summer and autumn. What you see hanging from the bark is the fruiting body: the mature, harvestable mushroom. That distinction matters more than it sounds, and it’s the next thing worth understanding.

02 — Fruiting body vs. mycelium

Why we use the real mushroom.

A mushroom has two parts. The mycelium is the root-like network that grows through the substrate; the fruiting body is the mushroom itself — the part you’d recognise on a plate. Many supplements are grown on grain and sold as “mycelium on grain” — cheaper to produce, but largely starch from the grain it grew on.

We use fruiting bodies only. They cost more and yield less, but they keep the ingredient simple: the actual mushroom, extracted, measured, and made easy to add to your day.

03 — Extraction

What “dual-extract” means.

Some of the mushroom’s compounds are water-soluble; others only release in alcohol. A dual extraction uses both hot water and alcohol, then recombines them — so the final extract represents more of the mushroom than water alone can pull out.

We standardise every batch to at least 30% beta-glucans — the structural polysaccharides used industry-wide as a marker of a genuine, well-made fruiting-body extract. It’s a compositional fact we can measure and print on the jar, not a promise about how you’ll feel.

“We trust numbers more than promises. So we tell you what’s in the jar — not what you’re supposed to feel.”
04 — The craft

Made in Lisbon, in small batches.

Everything is blended and packed by hand in Lisbon, in small runs — the kind where the batch number on the tin still means something. The coffee for First Light is single-origin arabica; the cacao for Last Light is dark drinking chocolate. The Lion’s Mane is the same dual-extract across the whole range — the only thing that changes is the ritual you fold it into.

That’s the whole idea: caring for a clear head should feel like a pleasure you reach for, not a supplement you endure.

The science

Read the research.

We link the papers because you should be able to check the source. This isn’t a verdict — just a useful place to start, with human trials and reviews on Hericium erinaceus.
