How does a fruiting body extract differ from mycelium-based products? — Hericium erinaceus (Lion's Mane) Extract, 500mg, 60 Capsules – Herbin

On the mushroom supplement market, there are two fundamentally different types of raw material: fruiting body extract and products based on mycelium grown on a grain substrate.

The fruiting body is the visible "cap" part of the mushroom, traditionally used as food and in folk medicine in Asian countries. This is where the polysaccharides and other compounds of main interest in terms of composition are concentrated. HERBIN Lion's Mane contains fruiting body extract — this is stated in the product description.

Mycelium, by contrast, is the network of fungal threads — the root-like structure of the mushroom. It is often grown on rice or oats, and in the finished product a significant share of the mass may be starch from the grain substrate rather than the mushroom material itself. This affects the final composition of the capsule.

When choosing a supplement, it is worth paying attention to exactly what is stated on the pack: "fruiting body extract" or "mycelium" / "myceliated grain". This lets you compare products with each other in an informed way, without relying only on marketing wording.
