Buying Guide
Fruiting Bodies vs. Mycelium: What Matters Most
The source of your Lion’s Mane supplement makes a huge difference. Fruiting bodies, the part you see in nature, contain higher levels of beneficial beta-glucans. Many cheaper products use mycelium grown on grain, which dilutes the potency. Both NOW and Real Mushrooms use fruiting bodies, while Double Wood also relies on fruiting bodies for its extract. This focus on quality ensures you get the active compounds your brain needs.
Dosage and Potency Per Capsule
Each brand offers a different dose per capsule. NOW provides 500 mg per serving, which is a standard starting point. Real Mushrooms delivers a concentrated extract with over 30 percent beta-glucans, making each capsule more potent. Double Wood gives you 1,000 mg per serving, ideal if you want a higher dose without taking multiple pills.

Third-Party Certification and Quality Assurance
Trustworthy brands back their products with independent verification. NOW carries GMP certification and Non-GMO Project verification, so you know the manufacturing process is solid. Real Mushrooms uses third-party labs to confirm beta-glucan levels, and Double Wood evaluates its supplements in the USA for purity. These certifications give you confidence that what is on the label matches what is in the bottle.
Organic Ingredients and Allergen Considerations
If you prefer organic products, Real Mushrooms and Double Wood both offer organic Lion’s Mane. NOW uses organic Lion’s Mane as well, but it is not certified organic across all ingredients.
