What is in the capsule?
Both give 1 g in two capsules, but not the same thing. Real Mushrooms soaks the mushroom itself, the fruiting body, in hot water and dries the extract. Its label states 30% beta-glucan, about 300 mg a serving. Beta-glucan is the compound mushroom brands measure, so a stated amount lets you compare.
Host Defense grows mycelium, the root-like part of the fungus, on organic brown rice. It dries the two together without extracting them, so part of each capsule is rice. The label does not say how much, and it states no beta-glucan.
| Per serving | Real Mushrooms | Host Defense |
|---|---|---|
| A serving | 1,000 mg in 2 capsules | 1,000 mg in 2 capsules |
| What is in it | Extract of the mushroom itself (fruiting body) | Mycelium and the brown rice it grew on, dried together |
| Extracted? | Yes, in hot water | No |
| Beta-glucan on the label | 30% (about 300 mg a serving) | Not stated |
| Lab report | One, from SGS, on its product page | None found; no testing claim |
| Testing list | None found | None found |
| Bottle we price | 120 capsules, $34.95 | 120 capsules, $62.95 |
| Cost a day, list price | $0.58 | $1.05 |
| Our score | 6.5/10 | 4.5/10 |
Host Defense costs about 80% more a day, and you cannot tell how much beta-glucan you get for it. No study compares these two products.
Is either one third-party tested?
Neither is on NSF/ANSI 173, NSF Certified for Sport, Informed Choice or Informed Sport (read October 6, 2026), or on our September 22, 2026 copy of USP’s list. Real Mushrooms posts one lab report on its capsule page, from SGS (April 7, 2025): 30.5% beta-glucan, plus tests for metals and microbes. We found no lab report or testing claim from Host Defense.
Who should buy which?
| If you want | Buy |

Questions
Is Host Defense lion’s mane good?
It is a well-known brand, but it is not our pick. Its capsules hold lion’s mane mycelium grown on brown rice, with the rice left in, and the label states no beta-glucan, so you cannot tell how much beta-glucan you get. It costs $1.05 a day at list price, about 80% more than Real Mushrooms, which states its beta-glucan.
Is Host Defense lion’s mane mycelium or fruiting body?
Mycelium, the root-like part of the fungus. Host Defense grows it on organic brown rice and sells the two together; its page says the product contains “both the mushroom mycelium and the fermented rice substrate.” Real Mushrooms uses the fruiting body, the mushroom you can see.
Does Host Defense lion’s mane contain rice?
Yes. The label on file with NIH lists the 1 g serving as lion’s mane with fermented brown rice. The label does not say how much of the gram is rice.
Is Real Mushrooms lion’s mane third-party tested?
It posts one lab report on its product page, from SGS (April 7, 2025): 30.5% beta-glucan, plus tests for metals and microbes. It is not on a public testing list (NSF, Informed or USP; read October 6, 2026). Neither is Host Defense.
Which is cheaper?
Real Mushrooms. At each brand’s list price, a day (2 capsules, 1 g) is $0.58 for Real Mushrooms and $1.05 for Host Defense.
