The Top Medicinal Mushrooms and Their Proven Health Benefits

Jun 19, 2025

( I saw this one in New Zealand! Amanita Muscaria: can cause hallucinations and psychotic reactions).

❗ Do not forage or consume wild mushrooms unless you are properly trained in mycology. Many toxic species closely resemble edible or medicinal mushrooms and can cause serious illness or death.
✅ Only purchase organic mushroom supplements and products from reputable companies that follow organic farming standards and FDA Good Manufacturing Practices (GMP). Look for third-party testing and transparent labeling to ensure purity, potency, and safety.

1. Lion’s Mane (Hericium erinaceus)

Cognitive function in older adults: A 16-week RCT of 3 g/day in adults aged 50–80 showed significant improvements in mild cognitive impairment; benefits declined after stopping supplementation.
Acute effects in healthy young adults: A 2023 trial reported faster processing speed (Stroop task) and reduced stress after a single dose and 28 days of supplementation.
Working memory & mood: Supplementation with MycoThrive™ (1 g single dose) improved attention, reaction time, and subjective happiness.
Mood & cognition review: A 2024 systematic review confirmed modest cognitive and mood benefits in middle-aged/older adults.

2. Reishi (Ganoderma lucidum)

Immune modulation in healthy adults: A 2022 RCT using β‑glucan showed increased CD3+, CD4+, CD8+ T‑cells, a higher CD4/CD8 ratio, and enhanced NK activity—no adverse effects.
Fatigue, mood, and appetite: A 2024 study identified improvements in fatigue, depression, nausea, and appetite among participants.
Cancer treatment adjunct: Ganoderma spores‑derived β‑glucan reduced chemotherapy side-effects and modulated tumor microenvironment.

3. Turkey Tail (Trametes versicolor)

Immune support in oncology: Extracts containing PSK and PSP continue to support immune function and are approved as adjunctive cancer therapies in Asia, showing benefits in NK, T cell, and macrophage activity.

4. Chaga (Inonotus obliquus)

Antioxidant & anti-inflammatory (lab studies): Since 2021, in vitro research confirms potent antioxidant activity and DNA protection via polyphenols and melanin. Animal trials indicate blood sugar and cholesterol modulation. (No major RCTs yet)

5. Shiitake (Lentinula edodes)

Immune and antiviral properties: Polysaccharides including lentinan remain well-supported for boosting immunity and antiviral defense.
Cardiovascular and oral health: Though historically noted for cholesterol reduction, recent clinical trials post-2021 are limited.

6. Maitake (Grifola frondosa)

Metabolic regulation & immune support: D‑fraction beta‑glucans offer potential improvements in insulin sensitivity and immune function, primarily shown in pre-2021 studies—more recent RCTs are awaited.

7. Agaricus blazei

Anti-inflammatory and anti-cancer: Initial clinical studies show proteoglucans can reduce inflammation and support immune response, with ongoing research in adjunct cancer use (no new high-quality RCTs yet).

8. Enoki (Flammulina velutipes)

Antioxidant, antiviral, and neuroprotective: Recent preclinical studies present promising in vitro effects; however, human trials remain lacking.

9. Poria (Poria cocos)

Traditional use with emerging support: Known for diuretic, sedative, and digestive benefits in TCM; recent lab work highlights anti-inflammatory and immunoregulatory properties but lacks clinical validation.
