Five things on a label decide whether you are buying a supplement or expensive flour. Everything else is packaging.
1. Which part of the mushroom
Look for 'fruiting body' stated explicitly. If a label says 'mycelial biomass' the weight includes the grain it grew on. If it names no part at all, assume the least favourable reading — brands with a good answer print it.
2. Beta-glucans, as a percentage
This is the number that matters. 25% or higher indicates a genuine extract; the best reach 30%+. If the label states 'polysaccharides' instead, that figure includes starch and is not comparable.
3. Extraction
Hot water extraction at minimum, dual extraction preferably. Unextracted powder is food, not a supplement — the chitin in mushroom cell walls is largely indigestible to humans.
4. Third-party testing
A beta-glucan percentage nobody verified is a marketing claim. Look for a named lab and an accessible certificate of analysis. Mushrooms also concentrate heavy metals from their growing medium, so a contaminant screen is worth as much as the potency test.
5. A dose you can actually reach
Work out the cost of getting to 1,000–3,000 mg of actual extract per day. Products with a low per-serving dose can look cheap per bottle and be expensive per effective dose.
Fruiting body, dual extracted, beta-glucans stated at 25% or higher, third-party tested, at a dose you can afford daily. Five checks, and most of the shelf fails at least two.
Questions about this
Frequently asked
What is the best lion's mane supplement?
Rather than name one, use the five checks: fruiting body stated, dual extracted, beta-glucans at 25% or above, third-party tested with an accessible certificate, and a cost per effective dose you can sustain. Most products fail at least two, and the ones that pass all five are comparable to each other.
How much should lion's mane cost?
Judge it per effective dose, not per bottle. A cheap product at 200 mg per serving of unextracted mycelium is more expensive per gram of actual beta-glucan than a pricier concentrated extract.
Does organic matter?
More than usual, because mushrooms concentrate whatever is in their growing medium, including heavy metals. Organic certification helps; a third-party contaminant screen helps more.
