Medicinal mushrooms have been used for thousands of years in traditional Chinese and Japanese medicine. Scientific research has been growing since 2000: Lion's Mane for the brain, Reishi for stress and sleep, Chaga for antioxidant protection, Cordyceps for energy, Maitake for immune modulation. Quality depends on two things: (1) extract of fruiting body vs mycelium, and (2) standardized beta-glucan content.

Our mushroom categories

• Lion's Mane — Hericium erinaceus — for brain, focus, and nerve health
• Reishi — Ganoderma lucidum — adaptogen for stress and sleep
• Chaga — Inonotus obliquus — antioxidant-rich, for immune balance
• Cordyceps — for energy, endurance, and VO2max
• Maitake — Grifola frondosa — beta-glucan-rich immune modulator
• Oyster Mushroom — Pleurotus ostreatus — nutrient-rich and cholesterol-modulating
• AHCC — patented shiitake extract for immune support
• Four Sigmatic — Finnish brand with mushroom coffee and cacao

Fruiting body or mycelium — which should I choose?

The fruiting body (the visible mushroom) generally contains a higher concentration of beta-glucans and triterpenes than mycelium-on-grain (a cheaper production method). For most classic varieties (Lion's Mane, Reishi, Chaga), fruiting body extract is preferred.

An exception is Cordyceps militaris — mycelium is commonly used because the wild fruiting body is very scarce and expensive.

What are beta-glucans?

Beta-glucans are polysaccharides found in the cell walls of mushrooms (and grains). For mushroom extracts, bioactive quality is often measured as a beta-glucan percentage — typically 20-40% for a good extract. General polysaccharides without specification say little.

Frequently asked questions

Which mushroom should I try first?

For focus: Lion's Mane (morning, 500-1000 mg). For stress/sleep: Reishi (evening, 500-1500 mg). For energy and sports: Cordyceps (morning, 1000-3000 mg). For immune maintenance: Chaga or Maitake.

Can I use multiple mushrooms at once?

Yes. A popular combination: Lion's Mane (morning, focus) + Reishi (evening, relaxation). Or a multi-mushroom blend for broad effect. Start with one variety to learn your response before stacking.

How long before I notice an effect?

Acute effects (especially from Cordyceps and strong doses of Lion's Mane) often within days. Adaptogenic effects of Reishi and Chaga: 2-6 weeks. Give a mushroom at least 6-8 weeks to work.

Are mushroom supplements scientifically backed?

For Lion's Mane, Reishi, and Cordyceps, dozens of human studies exist, mostly small-scale but consistently positive. For other species, the evidence is still more limited. EFSA has not approved official health claims for mushrooms — claims on labels therefore remain general or refer to traditional use.

Are mushroom supplements vegan?

Mushroom extract itself is vegan. Just pay attention to the capsule (gelatin vs hypromellose).

Combine with other categories

Mushrooms combine well with other thematic categories:

• Brain & Focus — Lion's Mane + omega 3 + B-complex
• Sleep & Relaxation — Reishi + magnesium
• Immune & Resistance — Chaga + Maitake + vitamin D
• Stress & Adrenal — Reishi + ashwagandha + B-complex
• Sports & Nutrition — Cordyceps + creatine + magnesium
