Best for Someone who specifically wants erinacines, which our lion’s mane page says come from mycelium, and prefers a grain-free source to mycelium on rice or oats.

How we evaluated it
Why we chose it What put it on our list
- It answers the main objection to mycelium. The mycelium is grown in liquid, separated from the liquid and freeze-dried, so the powder holds no grain substrate. The supplier (Nammex) says it has no added starch or filler.
- It measures the compound that mycelium is bought for. The label gives 5 mg of erinacine A per 2 capsules, and the page shows an Omnient Labs certificate (no. 26-182.1, lot 10026, UPLC) at 6.219 mg per serving against a minimum of 5 mg.
- Contaminant results are posted. An SGS Canada report for sample 10026, the same number as the Omnient lot (no. VR26-03674.012, July 2026), shows arsenic below 0.05, cadmium 0.03, mercury below 0.05 and lead below 0.01 ppm, with no E. coli, Salmonella or Staphylococcus aureus in 10 g and yeast and mold under 20 CFU/g.
- Purity-IQ lists Real Mycelium as authenticated Hericium erinaceus (mycelium) by NMR.
- The capsule is plain: hypromellose, silicon dioxide and stearic acid, with nothing else listed.
Trade-offs What to weigh before you buy
- The reports cover one sample, number 10026, which Omnient calls a lot. The Omnient certificate says its method was “performed by an outsourced lab” and that Omnient is not accredited for the tests marked, and it does not name the other lab.
- There is no starch figure and no stated origin. The page says no grain, no starch and no fillers, but posts no starch or alpha-glucan result. It is not organic: the supplier says some of its liquid-culture inputs are not certified organic.
- It is new and costs more. The product page was published in June 2026, so it has little track record. At about $1.67 a serving it costs roughly three times as much as Real Mushrooms’ own lion’s mane powder, which is sold for its beta-glucan instead.
- The label has no beta-glucan figure, since mycelium is not bought for it. The supplier says two published human trials used this ingredient; we did not check them. Our lion’s mane page covers the wider evidence, which is two small trials.
What to know Details worth knowing first
Our lion’s mane page notes that erinacines come mainly from the mycelium, while hericenones come from the fruiting body. Most mycelium products are grown on grain and contain a lot of it. Real Mycelium takes a different route: lion’s mane mycelium grown in liquid, freeze-dried, and labeled at 5 mg of erinacine A a serving.
That is the right thing to measure, and it avoids the grain problem. The product page also shows two lab reports for one lot: an Omnient Labs certificate with erinacine A at 6.2 mg a serving, and an SGS Canada report with low metals and clean microbe tests. What is missing is a starch figure to back the “no grain” claim, and the origin. It is also new, not organic, and about three times the price per serving of Real Mushrooms’ own lion’s mane powder.
We are asking Real Mushrooms for a starch result, for the name of the lab that ran the erinacine A assay, and for where the mycelium is grown. If erinacines are what you want, this product states the amount and shows a lab result for it. If you just want lion’s mane, the fruiting-body powder is cheaper and has beta-glucan results behind it.
Quality & testing How it measures up against our checklist
- Third-party tested
- Yes
- Tested by
- SGS Canada (metals, microbes) and Omnient Labs (erinacine A), one lot
| What we checked | What we found |
|---|---|
| Fruiting body or mycelium, stated Maker’s claim | Mycelium, stated on the label as ErinaPrime Lion’s Mane (mycelium). Grown in submerged liquid culture, separated and freeze-dried, with no grain substrate, per the maker and its supplier. |
| Measured active compound Verified | Label: erinacine A 5 mg per 2 capsules. Omnient Labs certificate of analysis 26-182.1 (lot 10026, sample received 2026-05-28, tested 2026-06-08, reported 2026-06-16): 6.219 mg per serving by UPLC against a specification of at least 5 mg. One lot; the method was outsourced and that lab is not named. |
| Starch or alpha-glucan reported Not verified | No figure. The page says no grain, no starch and no fillers. |
| Tested for contaminants Verified | SGS Canada report VR26-03674.012 for client sample 10026, the same number as the Omnient lot (received 2026-06-18, signed 2026-07-03): arsenic below 0.05, cadmium 0.03, mercury below 0.05 and lead below 0.01 ppm (USP <232>/<233>, ICP-MS); total aerobic count below 100 CFU/g; E. coli, Salmonella and S. aureus absent in 10 g; yeast and mold below 20 CFU/g. One lot. SGS says a third-party lab ran the microbial tests. |
| A named species Verified | Hericium erinaceus, mycelium. Purity-IQ’s public listing for Real Mushrooms shows Real Mycelium as authenticated by NMR. |
| Origin and organic certification Not verified | Where it is grown is not stated. Not organic: the supplier says not all the liquid-medium inputs are certified organic. The supplier, Nammex, was founded by Jeff Chilton, who co-founded Real Mushrooms with his son Skye, per the maker’s story page. |
| Extract or powder, stated Maker’s claim | Whole freeze-dried mycelium powder in capsules, not an extract. |
| Recalls, warning letters and Prop 65 Verified | No FDA warning letter is for Real Mushrooms or Nammex (the one hit for “real mushrooms” is a 2025 letter to other companies about dog treats), and no Prop 65 notice names Real Mushrooms or Nammex in the California Attorney General’s database. |
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 Mushroom Powder Fruiting body, organic by the maker’s claim, with an SGS report on the page for beta-glucan, metals and microbes. Costs about a third as much per serving.
- Mycelium on grain (rice, oats or sorghum) Cheaper, but much of the powder is grain, and Real Mycelium’s supplier says erinacine A in these products is typically below the detection limit. Look for an erinacine A figure and a starch figure before you buy.
