How we evaluated it
Why we chose it What put it on our list
- Beta-glucan is measured and the method is named. The maker posts SGS Canada report VR26-02726.002 for its 150 g pouch (completed 27 May 2026): beta-D-glucan by the Megazyme K-YBGL assay reads 40.9%. The label claims 300 mg in each 1 g serving, which is 30%.
- The same report gives metals by ICP-MS (arsenic below 0.05, cadmium below 0.01, mercury below 0.05, lead 0.08 ppm) and microbes (E. coli, Salmonella and S. aureus absent in 10 g; yeast and mold below 20 CFU/g).
- It is fruiting body only. The label says “No grain, no starch, no fillers,” and the maker says it uses 100% hot-water-extracted fruiting bodies, not mycelium on grain.
- Purity-IQ, an outside authentication program, lists Real Mushrooms Lion’s Mane as authenticated Hericium erinaceus by NMR.
- About $0.58 a serving in the 60 g pouch, and about $0.47 in the 150 g pouch ($69.95).
Trade-offs What to weigh before you buy
- The SGS report covers one sample of the 150 g pouch, and Real Mushrooms chose to post it. It says it tests every lot, which we could not check. Ask for the report for your lot.
- The report has no alpha-glucan or starch result, and none for hericenones, which the page mentions. The beta-glucan digits are partly overprinted by a column header on the posted image.
- It is a hot-water extract with no alcohol step, and the label does not give an extract ratio, so 1 g cannot be converted into grams of dried mushroom. Human trials used 1 to 3 g a day of dried fruiting body or an equivalent extract.
- We found no listing for Real Mushrooms in the USDA Organic Integrity Database. Its extract supplier, Nammex, is listed, so “organic” on the finished powder rests on the label.
What to know Details worth knowing first
Mushroom supplements are easy to mislabel. Many are mycelium grown on grain, and the “polysaccharides” on their labels can be mostly starch. Our mushroom guide explains the difference. This powder is the other kind: an extract of lion’s mane fruiting bodies with its beta-glucan measured.
What earns it a place is the paperwork. Real Mushrooms posts an SGS Canada report on its product page. It names the beta-glucan method (Megazyme K-YBGL, the assay ConsumerLab says it uses) and shows metal and microbe results. SGS is an outside lab, but this is one sample the maker chose to show, so ask for the report for your own lot.
Two things we could not confirm. The report has no alpha-glucan or starch result, and we found no listing for Real Mushrooms in the USDA Organic Integrity Database, so “organic” rests on the label. Evidence for lion’s mane itself is two small human trials; read our lion’s mane page before you decide it is worth the money.
Quality & testing How it measures up against our checklist
- Third-party tested
- Yes
- Tested by
- SGS Canada (report posted by the maker); Purity-IQ (species identity)
| What we checked | What we found |
|---|---|
| Fruiting body or mycelium, stated Maker’s claim | Fruiting body only. The label reads “No grain, no starch, no fillers,” and the product page says 100% hot-water-extracted fruiting bodies. |
| Measured beta-glucans Verified | SGS Canada report VR26-02726.002 (RM-LM150 pouch, sample 25825, received 6 May 2026, completed 27 May 2026): beta-D-glucan by Megazyme K-YBGL, 40.9%. One sample, posted by the maker. |
| Starch or alpha-glucan reported Not verified | No alpha-glucan or starch result is posted. Real Mushrooms says it tests every lot for beta-glucan and that the product has no added starch. |
| Tested for contaminants Verified | Same SGS report: arsenic below 0.05, cadmium below 0.01, mercury below 0.05, lead 0.08 ppm (ICP-MS, USP <232>/<233>). Total aerobic count below 100 CFU/g; E. coli, Salmonella and S. aureus absent in 10 g; yeast and mold below 20 CFU/g. No pass or fail limits are printed on it. |
| Comparison tests by others Maker’s claim | ConsumerLab’s lion’s mane and chaga review (updated 2025-09-15) lists Real Mushrooms Lion’s Mane among 12 products it tested. Real Mushrooms says ConsumerLab found its lion’s mane the best of those tested. The verdicts are paywalled, so we could not check. |
| A named species Verified | Hericium erinaceus. Purity-IQ’s public listing for Real Mushrooms shows Lion’s Mane as authenticated by NMR. The listing gives no lot numbers or values. |
| Origin and organic certification Maker’s claim | The maker says its extracts come from certified organic mushrooms grown in China (supplier Nammex). The label says certified organic by QAI. No Real Mushrooms listing in the USDA Organic Integrity Database; Nammex Mushrooms Inc. is listed as certified by QAI (status effective 24 January 2022). Nammex was founded by the father of a Real Mushrooms co-founder, per the maker’s story page. |
| Extract or powder, stated Maker’s claim | Hot-water extract: the label lists 1,000 mg of mushroom extract per 1 g serving. No extract ratio is given. |
| Recalls and warning letters Verified | No FDA warning letter names Real Mushrooms or Nammex in a search of fda.gov’s warning letters on 2026-10-22. |
What the labels mean
- Verified We opened an independent record that confirms it: a certifier’s listing, a regulator’s list or a lab report. It is linked under Sources.
- Maker’s claim The maker says so on its own page or label. We read it but found no independent record.
- Not verified We looked and could not confirm it, or the maker does not say. Treat it as unknown.

Alternatives Other options to compare
- Real Mushrooms Organic Lion’s Mane Extract Capsules The same maker’s capsules, 120 for approx. $35. We found no lab report posted for them.
- Real Mushrooms Real Mycelium Lion’s mane mycelium grown in liquid, with 5 mg of erinacine A a serving, at approx. $50 for 60 capsules. New, and we could not open its test report.
- Mycelium-on-grain lion’s mane powders Often cheaper per gram, but the label may not report starch, so the “polysaccharides” figure can be mostly grain. See what to look for.
