Magnesium Glycinate vs Reishi Mushroom (Ganoderma lucidum)

Mechanism

Magnesium is a cofactor for >600 enzymatic reactions including all ATP-dependent reactions (Mg-ATP is the true substrate), DNA/RNA polymerases, and ion channel regulation. Magnesium glycinate chelate provides highly bioavailable elemental magnesium bound to glycine. The glycine moiety itself is an inhibitory neurotransmitter (glycine receptors) and NMDA receptor co-agonist at the glycine binding site. The chelated form minimizes the osmotic laxative effect of ionic magnesium salts. Magnesium regulates NMDA receptor gating (voltage-dependent Mg2+ block), GABA-A receptor potentiation, HPA axis modulation, and parathyroid hormone secretion.

Standard Dosing

200-400mg elemental magnesium daily

Timing

Evening/bedtime (promotes relaxation and sleep quality). Can split AM/PM.

Cycle Duration

ongoing

Side Effects

• Drowsiness
• Mild GI discomfort
• Loose stools (less than other Mg forms)
• Hypotension at very high doses

Contraindications

• Severe renal insufficiency (impaired Mg excretion — risk of hypermagnesemia)
• Myasthenia gravis (Mg can worsen neuromuscular junction blockade)
• Heart block (Mg slows AV conduction)

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
