Cordyceps Militaris vs Reishi Mushroom (Ganoderma lucidum)

Mechanism

Cordyceps contains cordycepin (3'-deoxyadenosine) and adenosine, which modulate purinergic signaling. Cordycepin activates AMPK, inhibits mTOR, and modulates adenosine receptors (A1, A2A, A3). It enhances cellular ATP production by upregulating mitochondrial biogenesis genes and improving oxygen utilization efficiency. Cordyceps increases EPO production (erythropoietin) via HIF-1alpha stabilization, enhancing oxygen-carrying capacity. Beta-glucans (1,3/1,6) activate innate immune cells via Dectin-1 and complement receptor 3 (CR3). It also relaxes bronchial smooth muscle and enhances adrenal hormone production.

Standard Dosing

1000-3000mg daily (fruiting body extract) or 500-1000mg (concentrated 10:1 extract)

Timing

Morning or pre-workout (energizing). Avoid evening dosing.

Cycle Duration

Cycle 8-12 weeks on, 2 weeks off, or continuous

Side Effects

• Mild GI upset
• Dry mouth
• Insomnia if taken late
• Rare: nausea
• Rare: allergic reaction in mold-sensitive individuals

Contraindications

• Autoimmune conditions (immunostimulatory)
• Bleeding disorders
• Pre-surgery (discontinue 2 weeks prior)

Mechanism

Reishi contains triterpenoids (ganoderic acids, >130 identified) and polysaccharides (beta-glucans). Ganoderic acids inhibit histamine release, 5-alpha-reductase (DHT reduction), and ACE (angiotensin-converting enzyme). Beta-glucans (1,3/1,6-D-glucan) activate innate immunity via Dectin-1, CR3, and TLR-2 receptors on macrophages, dendritic cells, and NK cells. Reishi modulates the adaptive immune system by promoting Th1/Th2 balance and enhancing regulatory T-cell function. It also supports GABAergic signaling (calming effect), inhibits NF-kB, and modulates gut microbiome composition. Triterpenes support liver function via Phase I/II enzyme modulation.

Standard Dosing

1000-3000mg daily (dual extract: hot water + alcohol for both polysaccharides and triterpenes)

Timing

Evening preferred (calming, supports sleep). With meals.

Cycle Duration

ongoing or cycle 12 weeks on, 4 weeks off

Side Effects

• GI upset
• Dry mouth/throat
• Dizziness
• Nosebleeds (antiplatelet effect)
• Rare: hepatotoxicity (powdered whole mushroom products)
• Skin rash

Contraindications

• Autoimmune conditions (active flare — immunomodulatory)
• Bleeding disorders
• Pre-surgery (discontinue 2 weeks prior)
• Organ transplant recipients on immunosuppressants
