Short answer: Real Mushrooms wins for anyone who wants a verifiable lion's mane dose. Its capsules are 100% fruiting-body hot-water extract with a stated beta-glucan content above 25% and batch COAs published on the brand site, and the 120-count bottle was verified in stock at $34.95 on August 23, 2026. Om wins on price and on a trust story no extract brand can match: it grows its own mushrooms in California under USDA Organic certification. Its lion's mane capsules were $29.99 and the powder $18.20 on the same check.
The reason this matchup matters is that the two brands are not selling the same thing. Real Mushrooms sells a concentrated extract and tells you how concentrated it is. Om sells a whole-food powder, made from mushroom material it cultivates itself, and does not state an extract ratio or a beta-glucan percentage. That single difference decides almost everything else: dose per capsule, what you can verify from the label, and what you are paying for.
We compared the two on sourcing disclosure, stated potency, third-party testing, price per serving, and format options, using live Amazon listings and the brands' own published specifications. Our standing rule applies: a stated beta-glucan number on real fruiting body beats a label you cannot check.

The short version
- Real Mushrooms = the verifiable pick: 100% fruiting-body extract, more than 25% beta-glucans stated, batch COAs public. 120 capsules verified in stock at $34.95 on August 23, 2026.
- Om = the value and grower pick: USDA Organic, cultivated in Om's own California facility, whole-food powder. Capsules $29.99, powder $18.20 on the same check, both rated 4.5 stars by thousands of Amazon buyers.
- Om does not state an extract ratio or beta-glucan percentage, so you cannot verify concentration from its label the way you can with Real Mushrooms.
- Per Om's product description its lion's mane is whole-food powder that includes mycelial biomass grown on organic oats, which is a different input from fruiting-body extract; read our fruiting body vs mycelium guide before deciding how much that matters to you.
- If you take lion's mane as a daily smoothie or coffee mix-in and want the lowest cost per scoop, Om's powder is the cheaper habit. If you want a measured extract dose, Real Mushrooms is the benchmark.
- Any effect people chase from lion's mane builds over weeks; the NGF mechanism behind the interest is preclinical research, not proven human outcomes.

01 · Best for Verifiable Potency
Our PickOrganic Lion's Mane Extract Capsules (120 ct)
Fruiting-body extract with a stated beta-glucan number and public COAs; the category benchmark.
Lab report: 100% fruiting-body hot-water extract, more than 25% beta-glucans stated on the label, batch certificates of analysis published on the Real Mushrooms site. Certified organic, third-party tested.
Real Mushrooms was built around a single argument: that a lion's mane supplement should be made from the mushroom itself and should tell you what is in it. Its capsules deliver 100% fruiting-body hot-water extract with more than 25% beta-glucans stated on the label, and batch COAs are published so you can see the number rather than take it on faith. That is still rare in this aisle.
The honest limits: this is a standard-potency extract, not an 8:1 dual extract, so if maximum concentration is the goal our dual-extract ranking covers stronger options. The large powder tub is expensive at $69.95. As a dietary supplement it has not been evaluated by the FDA and is not intended to diagnose, treat, cure, or prevent any disease.

What we like
- Fruiting-body extract, stated and documented
- Beta-glucan content above 25% with public COAs
- 120-count bottle at a fair per-capsule price
- The benchmark product in the category
Worth noting
- Standard potency, not a dual extract
- Powder tub is expensive
- Earthy capsule taste if opened
Who should buy it: Anyone who wants a measured, verifiable lion's mane extract, and first-time buyers who want the safest benchmark product to start with.
What we don't like: Standard potency rather than ultra-concentrated, and the powder format is priced well above Om's.
Bottom line: Real Mushrooms is our pick because every claim on the label can be checked. The capsules are an extract of the actual mushroom, not mycelium on grain, and the brand states its beta-glucan content and publishes the lab work behind it. It is the product we hold every other lion's mane to, and at $34.95 for 120 capsules it is also one of the best transparency-to-price ratios in the category.

Lion's Mane Mushroom Capsules
USDA Organic lion's mane grown in Om's own California facility, milled as whole-food powder.
Lab report: USDA Organic, cultivated by Om in its US facility. Whole-food mushroom powder; per Om's description it includes mycelial biomass, primordia, and fruit bodies grown on organic oats. No extract ratio or beta-glucan percentage stated.
Om Mushroom Superfood is one of the largest functional mushroom growers in North America, and its lion's mane capsules are the clearest expression of that model: grown in Om's own facility, USDA Organic, milled as whole-food powder rather than extracted. At $29.99 on our August 23, 2026 check, with a 4.5-star average across roughly 1,800 Amazon ratings, it is one of the most-bought lion's mane products on the platform.
Where Om genuinely wins is the powder: $18.20 on the same check, 4.5 stars across more than 4,000 ratings, and the cheapest way on this page to keep a daily smoothie or coffee habit going. As a dietary supplement it has not been evaluated by the FDA and is not intended to diagnose, treat, cure, or prevent any disease.

What we like
- Grown in Om's own US facility
- USDA Organic
- Cheaper than Real Mushrooms in both formats
- Powder is one of the best-rated lion's mane products on Amazon
Worth noting
- No stated beta-glucan content or extract ratio
- Whole-food input includes mycelium on oats
- Not an extract, so less concentrated per gram
Who should buy it: Value-first buyers who want USDA Organic lion's mane from a grower they can name, especially as a powder mix-in, and who are comfortable trading a stated potency number for that provenance.
What we don't like: No extract ratio or beta-glucan percentage on the label, and the whole-food input includes mycelium grown on grain, so concentration is not verifiable the way it is with Real Mushrooms.
Bottom line: Om's argument is provenance rather than potency. Very few mushroom brands grow their own species, and Om does, under USDA Organic certification, which is a stronger trust story than most of the Amazon aisle. The trade is disclosure: the label does not state an extract ratio or beta-glucan content, so you cannot verify concentration, and the whole-food input includes mycelium grown on oats.
Key terms
- Fruiting body
- The actual mushroom. Real Mushrooms' extract is made only from fruiting bodies; Om's whole-food powder includes fruit bodies alongside mycelial biomass.
- Mycelial biomass
- The root-like network of the fungus, usually grown on a grain such as oats and dried together with it. Cheaper to produce than fruiting bodies; part of Om's stated input.
- Beta-glucans
- The measurable polysaccharide fraction of a mushroom product and the closest thing the category has to a verifiable potency marker. Real Mushrooms states more than 25%; Om does not state a figure.
- Hot-water extract
- Simmering the mushroom to pull out water-soluble compounds, then concentrating the result. Real Mushrooms' capsules are an extract; Om's powder is milled whole without a stated extraction step.
Questions, answered
Is Real Mushrooms or Om better for lion's mane?
Real Mushrooms, if you want a verifiable extract: 100% fruiting body, more than 25% beta-glucans stated, batch COAs published, $34.95 for 120 capsules on August 23, 2026. Om is the better value and the stronger provenance story, since it grows its own USDA Organic mushrooms in California, with capsules at $29.99 and powder at $18.20 on the same check, but it does not state an extract ratio or beta-glucan content.
Does Om lion's mane use fruiting body or mycelium?
Per Om's own product description, its lion's mane is a whole-food powder that includes mycelial biomass, primordia, and fruit bodies grown on organic oats. That means it is not a pure fruiting-body product the way Real Mushrooms is. Om is transparent about this; the thing to understand is that grain-grown mycelium generally carries less mushroom beta-glucan per gram than fruiting-body extract.
Is Real Mushrooms legit?
Yes. Real Mushrooms is an established specialist brand that publishes batch certificates of analysis, states its beta-glucan content, and makes its products from certified-organic fruiting bodies. It is the brand we use as the benchmark for the whole category, and its 120-count lion's mane capsules are the single most-purchased product by readers of this site.
Which is cheaper, Real Mushrooms or Om?
Om, in both formats. On August 23, 2026, Om's lion's mane capsules were $29.99 against Real Mushrooms at $34.95 for 120 capsules, and Om's powder was $18.20 against Real Mushrooms' large powder tub at $69.95. Per gram of stated beta-glucan, though, Real Mushrooms is the only one of the two you can actually calculate, because Om does not publish the number.
How much lion's mane should I take from either brand?
Follow the label. Human trials have used roughly 1.8 to 3.2 grams per day of fruiting-body powder, or about 1 gram of extract, for 4 to 16 weeks. A concentrated extract like Real Mushrooms needs less by weight than a whole-food powder like Om's. Our lion's mane dosage guide covers the study-backed ranges by format.
Are Real Mushrooms and Om safe to take daily?
Lion's mane is generally well tolerated in the published human studies, with mild digestive upset the most common complaint. Skip it if you are allergic to mushrooms, and check with a clinician first if pregnant, breastfeeding, on medication, or managing a condition. These statements have not been evaluated by the FDA; neither product is intended to diagnose, treat, cure, or prevent any disease.
