Glutathione- Summary
- AICAR is a cell-permeable AMP analog that activates AMPK (AMP-activated protein kinase) — the master metabolic switch that triggers fat burning, mitochondrial biogenesis, and adaptations normally only achieved through exercise. It has been called the 'exercise in a pill' compound.
- Glutathione is the body's master endogenous antioxidant tripeptide, composed of glutamate, cysteine, and glycine. It neutralizes reactive oxygen species, supports detoxification in the liver, recycles other antioxidants (vitamins C and E), and plays a central role in immune function, DNA repair, and cellular redox balance.

- Key Benefits
- AMPK activation mimics aerobic exercise adaptations
- Increased fat oxidation and endurance
- Mitochondrial biogenesis (PGC-1alpha)
- Improved insulin sensitivity and glucose metabolism
- Anti-inflammatory effects
- Potential cardiac protection during ischemia
- Synergistic with actual exercise training
- Reduces hepatic glucose production
- Primary endogenous antioxidant and free radical scavenger
- Supports hepatic detoxification of xenobiotics and heavy metals
- Recycles vitamins C and E to maintain antioxidant network
- Modulates immune function and T-cell activity
- Skin brightening via inhibition of tyrosinase (IV/topical routes)
- Neuroprotective in oxidative stress-related conditions
- Mitochondrial protection and energy metabolism support
- Side Effects
- Hypoglycemia risk
- Lactic acidosis at high doses (animal data)
- Injection site irritation
- Oral bioavailability is limited (largely hydrolyzed in gut); liposomal or sublingual forms preferred
- IV administration: rare allergic reactions, vein irritation
- High-dose supplementation may cause zinc depletion over time
- Inhaled glutathione may trigger bronchoconstriction in asthmatics
