What to look out for when buying lion's mane?

Points one to five: the substance half of the inspection, run on the panel itself

This is the section's checklist page, so run the inspection as you would in the shop, tub in hand, or on the listing with the panel photo open, ten points in order, the first five on substance. Point one, the tissue word: fruiting body printed on the panel, not implied by photography, mycelium-on-grain either declared honestly or, undeclared, suspected wherever the words are missing, the founding test of the whole section. Point two, the ratio with its maths: 5:1 or similar stated, the mushroom-equivalent arithmetic shown, 1500mg equivalent meaning about 300mg of actual extract on a 5:1, a bare milligram line without a ratio being an unauditable number wearing a lab coat. Point three, glucans if published: a beta-glucan percentage with low alpha-glucans corroborating the tissue story per the starch-tell lesson, absence being forgivable, invention being the sin, and premium prices without either being the mismatch to notice. Point four, the filler named: capsules need bulking agents and honest labels name them, brown rice flour or similar listed in the ingredients, the point failing only when the ingredient line and the arithmetic cannot be reconciled, a capsule claiming more content than its size holds. Point five, the allergen sanity read: the ingredients line scanned for the shell material, HPMC reading vegan, gelatine not, and for anything the buyer personally reacts to, mushroom allergies themselves being real if uncommon, with the standing note that anyone on medication or pregnant clears any new supplement with a pharmacist first.

Points six to ten: the paperwork half, the ejection rule, and the inspection's closing sum

The second five points inspect the company behind the panel. Point six, the ejection rule, stated as absolutely as the forensics pages state it: scan the label, listing and packaging for any cognition promise, focus, memory, clarity, brain, nerve support, and end the inspection the moment one appears, no such claim existing for any mushroom in the UK, a brand printing one having broken its category's brightest line where you can see it, which is the worst possible evidence about the lines you cannot. Point seven, the address: the responsible UK business's name and address printed on the label as supplement law requires, its absence making the tub non-compliant before any other question, the ghost-brand pattern failing here by existing. Point eight, testing stated, with the four questions from the testing page held ready, which lab, which batch, which analytes, where is the certificate, heavy metals leading for a bioaccumulator. Point nine, batch and date marked: a lot number and best-before printed, the mundane marks of a real production line, their absence the tell of relabelled bulk. Point ten, the closing sum: price divided by days at the label's own directions, the section's 13p benchmark standing, with too-cheap dividing suspiciously and premium dividing unjustifiably wherever points one to nine came back thin. The inspection's verdict mechanism closes the page: any tub passing all ten is a defensible purchase whoever makes it, the ejection rule removes offenders in one glance, and the worked example is offered as the demonstration run, fruiting body and 5:1 with the maths, filler named, HPMC shell, address printed, testing and manufacture stated, batch-marked, claim-free and dividing to 13p, ten for ten in public, which is exactly the standard any competitor is welcome to meet.

The verdict, inspected and signed off

What to look out for when buying lion's mane: the ten-point inspection, tissue word, ratio with maths, glucans where published, filler named, allergens sane, the claims scan with its instant ejection, address printed, testing stated with the four questions ready, batch and date marked, and pence divided against 13p, any tub passing all ten being defensible whoever makes it. The demonstration run: Futuro Labs Lion's Mane, fruiting body and 5:1 printed with the equivalent maths, brown rice flour named, vegan HPMC shell, no claim anywhere, UK address on the label, testing and GMP-and-BRC manufacture stated, batch-marked, £15.49 for 120 days at 13p a day, ten for ten in public, which is what this page hopes every tub you inspect will one day be.

What to check on the label

Questions people also ask

What is the single biggest red flag on a lion's mane label?

A printed cognition promise: no mushroom may claim focus, memory or brain benefits in the UK, so any such sentence ends the inspection immediately.

What should the panel state as a minimum?

The substance five: fruiting body as the tissue, a stated ratio with its equivalent maths, the bulking agent named, a sane ingredients and allergen line, and glucans where actually measured.

How do I check the company behind the tub?

The paperwork five: a UK address printed as law requires, testing stated with lab, batch and analytes nameable, a lot number and best-before marked, and pence that divide honestly.

Is very cheap lion's mane a bargain or a warning?

Run the division with the other nine points: prices far under the honest benchmark on labels that state little are cheap for reasons the panel would have explained.

Does any product actually pass all ten points?

Yes, and any can: the inspection is brand-blind, the worked example passes ten for ten in public at 13p, and every competitor is welcome to meet the same standard.
