Real Mushrooms Organic Reishi Mushroom Extract Powder

1. What is in it 25% of the rating 5 of 5

   One ingredient, a dual extract of organic reishi, with beta-glucan (250 mg) and triterpenoids (40 mg) stated and nothing else added. SGS measured 30.5% beta-glucan; the triterpenoids are unmeasured.

2. Independent testing 35% of the rating 3 of 5

   A maker-ordered SGS Canada report for this pouch (beta-glucan 30.5%, metals, microbes) and a second for the same extract in capsules. One sample each, no triterpene or starch result, and ConsumerLab’s independent test of it is members-only.

3. Evidence 15% of the rating 2 of 5

   Our reishi page has one small uncontrolled human trial and sleep findings from rats. The dual-extract form is the one it recommends, at the low end of the doses used.

4. Trust 10% of the rating 4 of 5

   No recall, FDA warning letter or Prop 65 notice. It pays affiliates 15% and its supplier was founded by a co-founder’s father.

5. Value 15% of the rating 2 of 5

   About $0.89 a gram of extract ($0.80 in the 100 g pouch), among the dearest extracts here.

• Independent ConsumerLab (subscription-funded) May 2026

  Real Mushrooms Reishi was one of seven reishi products ConsumerLab selected and tested for beta-glucan, triterpenes and metals (review published 21 May 2026). ConsumerLab’s brand page for Real Mushrooms confirms it selected two of the maker’s products for testing but hides how many were approved. The public summary says two of the seven were not approved for too little beta-glucan, three of the five approved were low in triterpenes, and none of the products tested for heavy metals failed. It does not say which products. Real Mushrooms’ blog says ConsumerLab picked its reishi as the best, with 264.5 mg of beta-glucan a serving; we could not check that. Open ↗ (opens in a new tab)

Is there a lab report for this exact powder?

Yes, though it is easy to miss. The product page’s “3rd Party Testing” button opens an SGS Canada report for the 45 g pouch (VR26-03674.003, completed 3 July 2026), and the maker’s reishi capsule page posts one for the capsules. Both were ordered and paid for by Real Mushrooms and cover one sample each. A July 2024 Reddit thread (opens in a new tab) records a buyer being refused third-party reports; the maker now posts SGS reports on its product pages, for its lion’s mane, Cordyceps-M and 5 Defenders as well.

Real Mushrooms says ConsumerLab picked its reishi as the best. Is that true?

ConsumerLab’s public summary (opens in a new tab) names a Top Pick without saying which: the one approved product with reishi mushroom rather than mycelium, a large amount of beta-glucan and the most triterpenes. Real Mushrooms’ blog (opens in a new tab) says that is its reishi and quotes 264.5 mg of beta-glucan a serving as ConsumerLab’s measurement. ConsumerLab’s brand page (opens in a new tab) confirms it tested two Real Mushrooms products but hides how many were approved or are Top Picks. The review covers six other brands, and the Top Pick could be one of theirs. A ConsumerLab member can check; we could not.

Does reishi work, and is it safe?

Our reishi page is blunt: one small uncontrolled human trial, with the sleep findings from rats. It may thin the blood, and rare case reports link powdered reishi to liver problems. See a clinician first if you take blood thinners.

Is the triterpene figure real? ConsumerLab found many reishi extracts low in them.

ConsumerLab’s summary says three of the five reishi products it approved were low in triterpenes. This label states 40 mg a gram, and the SGS report for the pouch does not measure triterpenes (the maker’s quality page names HPTLC and HPLC for such compounds in general). Dual extraction is meant to keep them, but nothing posted shows it did.

Is it NSF certified? Amazon’s listing says so.

Amazon’s bullets say “NSF Certified for Dietary Supplements.” NSF’s Certified for Sport directory lists only two Real Mushrooms products, 5 Defenders and Cordyceps-M capsules, not this powder, and the maker’s own page says only that it is made in an NSF-certified facility. NSF also certifies supplements under a general program that we could not search, so we cannot rule out a listing there.

Who is paid to promote it?

Real Mushrooms runs an affiliate program (opens in a new tab) that pays 15% of referred sales with no cap, so many “best reishi” lists are paid links. Its supplier, Nammex, was founded by the father of a Real Mushrooms co-founder, per its story page (opens in a new tab).

• One ingredient and nothing else: organic reishi extract, 1,000 mg a gram, with 250 mg of beta-(1,3)(1,6)-glucans (25%) and 40 mg of triterpenoids (4%) stated on the label.
• 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.
• Purity-IQ, an outside authentication program, lists Real Mushrooms Reishi as authenticated Ganoderma lingzhi by NMR.
• The page carries an SGS Canada report for this 45 g pouch (VR26-03674.003, completed 3 July 2026): beta-glucan 30.5% by the Megazyme method against 25% on the label, arsenic 0.35, cadmium 0.17, lead 0.13 and mercury below 0.05 ppm, and no E. coli, Salmonella or S. aureus in 10 g. The maker’s reishi capsule page posts a second report, for the same extract in capsules (35.1% beta-glucan).
• ConsumerLab chose it among seven reishi products to test in 2026. Its public summary says two of the seven were not approved for too little beta-glucan, three of the five approved were low in triterpenes, and none of the products tested for heavy metals failed. It does not say which product did what.
• About $0.89 a gram of extract in the 45 g pouch, and about $0.80 in the 100 g pouch ($79.95).

• The SGS report is one sample, ordered and paid for by Real Mushrooms, and it has no triterpene or starch result, so the 4% triterpenoid figure is the maker’s guarantee. Its arsenic (0.35 ppm, or 0.35 µg in a 1 g serving) is the highest in the Real Mushrooms reports we read. 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.

• 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.
