Before you spend a dollar on mushroom supplements, read this.

The mushroom supplement industry runs on confusion. Most products labeled "Lion's Mane" are mostly starch grown on grain. We built a 5-point checklist that takes 30 seconds on any product page and tells you whether what you're holding is actually worth your money.

Subscribing sends the checklist straight to your inbox — plus one weekly newsletter (one species, one news story, one product, one cultivation tip). No spam, unsubscribe in one click.

What the checklist covers

Five checks. Thirty seconds. Any product page.

Source material

Fruiting body or mycelium grown on grain? The single biggest determinant of whether the product contains the active compounds you're paying for. We show you how to spot it on any label.

Extraction method

Hot water for beta-glucans, alcohol for triterpenes, dual extraction for both. Different methods capture different compounds. We tell you which matches the benefit you want.

Beta-glucan content

The actual measured percentage — not "polysaccharides," a meaningless catch-all that includes the starch you don't want. We tell you the number to look for and how to read it.

Third-party testing

Does an independent lab verify what's in the bottle? Is the certificate of analysis public? We tell you what to look for and which brands publish theirs.

Price per gram of active compound

The per-bottle price is meaningless. The per-gram-of-beta-glucan price is the only number that matters. We show you the math in 30 seconds.
