Mushroom Capsules
Capsule brands vary more on testing transparency than on dose. Only 2 of the 8 brands checked here publish a specific beta-glucan percentage, and only 2 name an accredited or independent lab by name; the rest either claim third-party testing without saying who did it, test in-house, or disclose no testing at all.
What's in the capsule, brand by brand
Five of the 8 brands checked here, FreshCap, Gaia Herbs, Mushroom Revival, Nootropics Depot, and NOW Foods, state fruiting body only. Double Wood and Om Mushroom use a whole-mushroom blend that includes mycelium, and The Genius Brand's product is a 3-species mycelium-and-fruiting-body blend rather than a Lion's Mane-only capsule. Stated dose per serving ranges from 450 mg (Gaia Herbs, extract) to 1,000 mg (Double Wood, FreshCap, NOW Foods), with 2 brands, Mushroom Revival and Om Mushroom, not stating a milligram figure on their own product page at all.
