Research
What the research actually says.
Ten mushrooms, ten different evidence bases — one of them genuinely good, several thin, a couple close to non-existent. Here is all of it, including the parts that don't flatter us.
How to read this page
Most mushroom brands quote the strongest study they can find and leave out the dose. We publish the dose. For every ingredient below you get the same three things: what it is traditionally used for, what the human research actually measured, and how far our serving sits from the amount used in that research.
In most cases the honest answer is we are well below the studied dose. That is deliberate. Mushroom Complex 10X is a broad daily foundation across ten species, taken every morning for a quarter — not a clinical dose of one extract. If you want a study dose of a single mushroom, buy a single-ingredient extract instead. We will say that in a sales conversation and we are saying it here.
Nothing on this page is a claim that this product treats, prevents or cures anything. Where a study exists we give the reference so you can read it yourself.
Serving size is two vegetable capsules — 1,330 mg of mushroom material in total.
Lion's Mane
266 mg
Hericium erinaceus · fruiting body
Traditionally used to support mental clarity and focus. One of the most-studied functional mushrooms for cognitive support.
The honest read. The human trials that found something used 2,000–3,200 mg a day for four to sixteen weeks, in adults over forty. The most recent, better-controlled trials in healthy young adults were largely null. And the compound behind the single strongest cognition study exists only in mycelium — ours is fruiting body, so that study does not transfer to us.

Reishi
266 mg
Ganoderma lucidum · fruiting body
Traditionally used across East Asia for calm and resilience. Its beta-glucans support normal immune function.
The honest read. The one good fatigue trial used 5,400 mg a day in a clinical population — twenty times our serving. A 2025 meta-analysis of 17 randomised trials rated the certainty of the evidence very low across every outcome it examined. No reishi trial has ever used sleep as a primary endpoint, so we don't call it 'the sleep mushroom,' and we don't make cardiovascular claims for it either.

Cordyceps
266 mg
Cordyceps sinensis · mycelium powder
Traditionally used to support stamina and everyday energy.
The honest read. Mixed at best. Two small trials found changes in exercise measures at 999–3,000 mg a day; a well-run trial in trained cyclists at 3,000 mg a day found nothing at all. This is the ingredient people assume carries the energy story, and it is the one we lean on least.

Shiitake
266 mg
Lentinula edodes · fruiting body
Beta-glucans from shiitake support normal immune function.
The honest read. Quietly the best-supported ingredient in the formula. 52 adults eating 5–10 g of dried shiitake daily for four weeks showed clear changes in immune cell markers. Markers, though — the study did not measure whether anyone got fewer colds. And our panel states no extract ratio, so we can't claim our 266 mg is equivalent to those grams.
Dai 2015, J Am Coll Nutr (PMID 25866155)
Maitake
~44 mg
Grifola frondosa · fruiting body
Part of the ten-mushroom blend.
The honest read. The main human study used a purified fraction at far higher doses, and found that its immune effects ran in both directions depending on the dose — up at some, down at others. That single finding is why you will never see the words 'immune booster' on this site.
Deng 2009 (PMID 19253021)
Turkey Tail
~44 mg
Trametes versicolor · fruiting body
A traditional immune-supporting mushroom.
The honest read. Almost every impressive turkey tail statistic you will read online comes from a prescription medicine used in hospitals at 3,000–9,000 mg a day. That is 70 to 200 times what is in a serving here, in a completely different setting, and it has nothing to say about a daily capsule. We won't borrow it.
Pilkington 2022, Cochrane review — very low certainty
Chaga
~44 mg
Inonotus obliquus · fruiting body
Part of the ten-mushroom blend.
The honest read. There is no human efficacy trial for chaga at any dose. Everything you have read about it is test-tube or rodent work. It is here because a ten-mushroom blend that omits chaga isn't a ten-mushroom blend. It is also very high in oxalate, which is why our kidney caution exists — the documented cases involved 10–15 g a day, hundreds of times our amount.
Kidney case reports: PMID 35451393 · J Korean Med Sci 2020;35:e122
Royal Sun Agaricus
~44 mg
Agaricus blazei · fruiting body
Part of the ten-mushroom blend.
The honest read. The best-studied of the three obscure members: small placebo-controlled trials exist, at 1,800–5,400 mg a day. At around 44 mg, treat this as a blend member rather than an active dose. Rare liver case reports at gram-level doses are part of why we carry a liver caution and never write the words detox or cleanse.
Ohno 2011 phase I · Mukai 2006 (PMID 17105737)
White Button
~44 mg
Agaricus bisporus · fruiting body
Part of the ten-mushroom blend.
The honest read. The one solid finding about white button mushrooms concerns vitamin D — and only in mushrooms deliberately exposed to UV light. Nothing on our panel says UV-treated, so assume none. It is the most familiar mushroom on earth and we list it as exactly that: one of the ten, not a functional claim.
UV vitamin D RCT (PMID 21540874)
Black Fungus
~44 mg
Auricularia auricula · fruiting body
Part of the ten-mushroom blend. A staple of Chinese cooking for centuries.
The honest read. Its most documented pharmacological property is an effect on platelets — in a test-tube comparison of eight edible mushrooms it was the most potent, outperforming aspirin. At 44 mg the real-world risk is very low, but it is precisely why our warnings mention blood thinners and a two-week stop before surgery. That is a caution, not a selling point.
Antiplatelet screen (PMID 31842490)
The left column is what one serving contains. The middle column is what the best human trial for that ingredient actually used. We publish the gap because you would find it anyway.
The six mushrooms in the proprietary blend share 266 mg between them. The label declares the total, not the split, so the ~44 mg figures are an even-split assumption — not a stated fact. We would rather show you the assumption than hide it.
Built from the actual measurement points in the trials — not from what would sell best.
** Daily Value (DV) not established. Other ingredients: hypromellose (vegetable capsule), microcrystalline cellulose, magnesium stearate. Total mushroom material: 1,330 mg per serving.
Warnings. Consult your healthcare professional before use if you are pregnant, nursing, taking any medication, or have a medical condition. Speak with your doctor before use if you take blood-thinning medication (including warfarin, clopidogrel, aspirin or a DOAC), medication for diabetes or blood pressure, or immunosuppressant medication, or if you have a bleeding disorder, liver disease, kidney disease or a history of kidney stones. Discontinue use at least two weeks before any scheduled surgery. Not for use by persons under 18. Do not use if you have a known allergy to mushrooms or moulds. Keep out of reach of children. Discontinue use and consult a doctor if adverse reactions occur.
Why those specific cautions: the surgical hold and the blood-thinner line come from the platelet activity documented for black fungus, cordyceps and reishi. The liver line comes from rare case reports associated with reishi and royal sun agaricus at much higher doses. The kidney line comes from chaga's oxalate content, documented at gram-level intakes — several hundred times what one serving contains. The diabetes line comes from maitake. At our serving size the risk is very low; we list them because you deserve to make the call yourself.
