Futuro Labs Lion's Mane: label, dose and cost per day

By Tom Francis·Updated 2026-09-03·2 sources·Editorial policy

What is on the label

Futuro Labs Lion's Mane is a 120 capsule tub at 15.49 pounds on Amazon UK. The serving is one capsule, so the tub runs 120 days, which is the longest supply in the range.

Each capsule states 1500mg mushroom equivalent from a 5 to 1 extract. The listing also states 50 percent polyphenols. The capsule is vegan HPMC and the label declares brown rice flour as a bulking agent. It is UK made and GMP certified.

Mushroom equivalent is not extract weight

This is the single most misread figure in the mushroom supplement category. A 5 to 1 extract means five parts raw mushroom were used to produce one part extract. So 1500mg mushroom equivalent implies roughly 300mg of extract actually sitting in the capsule.

Both numbers are legitimate and both appear on labels across the category, which is why two products can look five times apart while delivering the same thing. A product quoting only a large equivalent figure with no ratio has told you nothing, because without the ratio the equivalent cannot be converted.

Zero authorised claims, stated plainly

Lion's mane has no authorised health claim in the UK or the EU. Not for focus. Not for memory. Not for brain fog, concentration, mood, nerve health or anything else it is routinely sold on.

That is not a technicality about paperwork. It means no claim in this area has been assessed and accepted, so any product marketed on a cognitive outcome is making a claim the regulator has not agreed to. Futuro Labs Lion's Mane is described on this site accordingly: a well specified extract at a low cost per day, bought on interest rather than on evidence.

Fruiting body, mycelium and why it matters

Lion's mane products are made either from the fruiting body, which is the mushroom itself, or from mycelium, which is the root structure and is usually grown on a grain substrate and milled with it.

A mycelium on grain product can contain a large proportion of grain by weight while still quoting an impressive milligram figure. That is the main reason the category has a reputation problem, and it is why the part of the mushroom used belongs on any label worth trusting.

The bulking agent, declared

Futuro Labs Lion's Mane declares brown rice flour as a bulking agent. A bulking agent is normal in a capsule product, because roughly 300mg of extract does not fill a capsule on its own and something has to occupy the rest of the volume.

What matters is that it is declared. A product claiming zero fillers while carrying a bulking agent has contradicted itself on its own packaging, and that is a fair signal about the rest of what it says.

What to check on any lion's mane label

• Is the extract ratio stated, or only a mushroom equivalent figure?
• Is it fruiting body or mycelium, and does the label say?
• If it is mycelium, is it grown on grain and is the grain included in the weight?
• Is a polyphenol or beta glucan figure given?
• How many capsules make the stated serving?
• Is the bulking agent declared?
• Pack price divided by servings, not capsules.

Cost per day, worked through

15.49 pounds divided by 120 single capsule servings is 12.9p a day, which rounds to 13p. That makes Futuro Labs Lion's Mane the cheapest daily serving in the range, below the omega 3 at 17p, the magnesium at 22p and the collagen at 28p.

That price matters more here than anywhere else on this site. With no authorised claim behind it, the entire rational case for trying lion's mane rests on the cost of being wrong being small.

What 50 percent polyphenols does and does not tell you

The listing states 50 percent polyphenols, which is more specification than most of the category offers and is still worth reading carefully.

Polyphenols are a broad class of plant compounds rather than the specific compounds the lion's mane research is interested in, which are generally hericenones from the fruiting body and erinacines from the mycelium. A polyphenol percentage is a standardisation marker: it says the extract has been made to a consistent specification rather than varying batch to batch.

That is genuinely useful, because the alternative is a milligram figure with nothing behind it. It is not evidence of an effect, and no authorised claim exists for lion's mane at any specification. Futuro Labs Lion's Mane is 13p a day and that price is the honest basis for trying it.
