Magnesium Glycinate vs Shilajit

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

Shilajit is a mineral-rich exudate containing fulvic acid (60-80%), dibenzo-alpha-pyrones (DBPs), and over 85 minerals in ionic form. Fulvic acid acts as an electron shuttle in mitochondrial electron transport, enhancing CoQ10 function and ATP production. DBPs protect CoQ10 from oxidation, extending its functional half-life. Shilajit increases total and free testosterone by stimulating steroidogenesis and reducing SHBG. It also enhances mitochondrial membrane potential, acts as a potent antioxidant (fulvic acid neutralizes free radicals), and improves mineral absorption by forming bioavailable fulvic acid-mineral complexes.

Standard Dosing

250-500mg purified shilajit daily (standardized to >50% fulvic acid)

Timing

Morning with warm water or milk (traditional Ayurvedic method). Can be split AM/PM.

Cycle Duration

Cycle 8-12 weeks on, 2-4 weeks off

Side Effects

• GI discomfort
• Dizziness
• Increased heart rate (rare)
• Allergic reaction (rare)
• Metallic taste

Contraindications

• Hemochromatosis (iron content)
• Active gout (may increase uric acid)
• Sickle cell disease
• Thalassemia
