Your review
Reviews are personal experiences, not research, and they never change our quality ratings. Every review is read by our team before it appears.
How we evaluated it
Why we chose it What put it on our list
- It is a dual extract of fruiting bodies, hot water then alcohol, which our reishi page recommends for a fuller profile: water pulls out the polysaccharides, alcohol the triterpenes.
- It states two numbers: more than 25% beta-glucan and more than 4% triterpenes.
- Purity-IQ, an outside authentication program, lists Real Mushrooms Reishi as authenticated Ganoderma lingzhi by NMR.
- The maker says beta-glucan is measured on every lot by the Megazyme K-YBGL method, and the SGS reports it posts for its lion’s mane and Cordyceps-M powders use that method.
- About $0.89 a serving in the 45 g pouch, and about $0.80 in the 100 g pouch ($79.95).
Trade-offs What to weigh before you buy
- We found no lab report for this reishi. The two reports Real Mushrooms posts cover other products, so the beta-glucan and triterpene figures here are the maker’s guarantee. The triterpene method is not named. Ask for the report for your lot.
- Reishi may have a blood-thinning (antiplatelet) effect, so ask a clinician first if you take blood thinners. Rare case reports link powdered reishi to liver problems, though the cause is unclear, and safety data run to 16 weeks.
- Human evidence is thin: our reishi page counts one small uncontrolled trial in people, and the sleep findings come from rats. The 1 g serving is at the low end of the 1 to 3 g of extract used in trials.
- 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
Reishi is usually bought for calm, sleep and immune balance, and our reishi page is blunt about the evidence: one small uncontrolled human trial, with the sleep findings coming from rats. If you try it anyway, that page recommends a dual extract, because water pulls out the polysaccharides and alcohol the triterpenes.
This is one. Real Mushrooms hot-water and alcohol extracts reishi fruiting bodies and states a beta-glucan minimum (above 25%) and a triterpene minimum (above 4%). Purity-IQ confirms the species. On paper, that fits our checklist.
It scores a 3, not a 4, because of what we could not find. Real Mushrooms posts lab reports for its lion’s mane and Cordyceps-M powders, but not for this one, so the figures are a guarantee, not a result. Ask the company for the report for your lot. Reishi may thin the blood, so check with a clinician if you take blood thinners.
Quality & testing How it measures up against our checklist
- Third-party tested
- Yes
- Tested by
- Purity-IQ (species identity only)
| What we checked | What we found |
|---|---|
| Fruiting body or mycelium, stated Maker’s claim | Fruiting bodies only. The page says 100% hot-water-extracted mushrooms (fruiting body) and no mycelium fermented grain. |
| Measured beta-glucans Maker’s claim | Guaranteed above 25% beta-glucan. The maker says every lot is measured by the Megazyme K-YBGL method. We found no reishi report; the SGS reports we opened are for other Real Mushrooms products. |
| Starch or alpha-glucan reported Not verified | Not reported. The page says no added starch, fillers or mycelium fermented grain. |
| Tested for contaminants Not verified | The maker says metals (ICP-MS) and microbes are tested on every lot. We found no contaminant report for this product. |
| A named species Verified | Ganoderma lingzhi. Purity-IQ’s public listing for Real Mushrooms shows Reishi 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 page says USDA-certified organic through QAI. No Real Mushrooms listing in the USDA Organic Integrity Database; Nammex Mushrooms Inc. is listed as certified by QAI. 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 | Dual extract, hot water and alcohol, 1,000 mg per serving. The triterpene minimum (above 4%) has no named method, and no extract ratio is given. |
| Comparison tests by others Maker’s claim | ConsumerLab’s reishi review (published 2026-05-21) tested Real Mushrooms Reishi among seven products. Real Mushrooms says ConsumerLab picked its reishi as the best of those tested. The public page calls the Top Pick the only product made from true reishi rather than mycelium, without naming it, so we could not tie it to this product. |
| 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 5 Defenders capsules A five-mushroom blend that includes reishi, approx. $40 for 90 capsules, and the only Real Mushrooms product with reishi that we found in NSF’s Certified for Sport database.
- Real Mushrooms Organic Reishi Extract Capsules The same extract in 90 capsules for approx. $40. Same gap: no report posted that we could find.
- Reishi made from mycelium on grain Often cheaper, but ConsumerLab warns that labels listing “mycelial biomass” first may hold a lot of alpha-glucan, a grain polysaccharide. See what to look for.
