OVERVIEW:
Glutathione is a tripeptide composed of three amino acids: glutamine, cysteine, and glycine
Known as the body's "master antioxidant" and most important intracellular antioxidant
Naturally produced in cells but declines with age, stress, and toxin exposure
WHAT DOES GLUTATHIONE DO?
Provides powerful antioxidant protection against free radicals
Supports detoxification of heavy metals and environmental toxins
Enhances immune system function and cellular health
Promotes skin brightening and anti-aging effects
Supports liver health and metabolic function
Reduces oxidative stress and inflammation
USES:
Anti-aging and longevity optimization
Detoxification and liver support • Immune system enhancement
Skin brightening and hyperpigmentation reduction
Athletic recovery and performance
Neurological protection and brain health
Support during illness or toxic exposure
Mitochondrial health and energy production
GLUTATHIONE RESEARCH
Master Antioxidant Function: Glutathione is the most abundant antioxidant in the body and plays a crucial role in neutralizing free radicals, reducing oxidative stress, and protecting cells from damage. It recycles other antioxidants like vitamins C and E, amplifying their effectiveness.
Detoxification Support: Glutathione is essential for Phase II liver detoxification, binding to toxins, heavy metals, and metabolic waste products to facilitate their elimination from the body. It's particularly important for neutralizing environmental pollutants and xenobiotics.
Immune System Enhancement: Glutathione supports optimal immune function by protecting immune cells from oxidative damage and supporting lymphocyte proliferation. Low glutathione levels are associated with compromised immune response and increased infection susceptibility.
Age-Related Decline: Glutathione levels naturally decline with age, contributing to increased oxidative stress, reduced detoxification capacity, and accelerated aging. Supplementation may help restore youthful glutathione levels and cellular function.
Skin Brightening Effects: Glutathione inhibits tyrosinase, the enzyme responsible for melanin production, leading to skin brightening effects. It's widely used in Asia and gaining popularity worldwide for addressing hyperpigmentation and achieving more even skin tone.
Neurological Protection: Glutathione protects brain cells from oxidative damage and supports neurological health. Deficiency is associated with neurodegenerative diseases including Parkinson's, Alzheimer's, and multiple sclerosis.
Potential Mechanism of Action: Glutathione works through multiple pathways:
Neutralizes reactive oxygen species (ROS) and free radicals
Conjugates with toxins in liver for elimination
Recycles and regenerates other antioxidants (vitamins C, E)
Supports mitochondrial function and energy production
Modulates immune cell function and cytokine production
Inhibits melanin synthesis for skin brightening
Protects cellular DNA, proteins, and lipids from oxidative damage
GLUTATHIONE LIFESTYLE SUPPORT
LIFESTYLE SUPPORT:
Sulfur-rich foods: garlic, onions, cruciferous vegetables
Whey protein to provide cysteine for glutathione synthesis
Selenium and zinc for glutathione enzyme function
Limit alcohol consumption (depletes glutathione)
Regular exercise (increases glutathione production)
Quality sleep (7-9 hours) for cellular repair
Reduce toxin exposure (smoking, pollution, chemicals)
WHAT TO EXPECT:
IMPORTANT: Effects vary based on administration method and baseline status!
Enhanced energy and reduced fatigue within days to weeks
Improved skin brightness and tone (2-4 weeks)
Better recovery from exercise and illness
Enhanced mental clarity and focus
Reduced oxidative stress markers
Long-term cellular protection and anti-aging benefits
Individual responses vary based on glutathione deficiency level
GLUTATHIONE DOSING + CYCLING
Injectable Glutathione Protocol (Most Effective):
Glutathione | BAC water added | Strength mg/mL | Dose | Frequency | Supply |
1000 mg Vial | 10 mL | 100mg/mL | 200-400mg | 2-3x weekly | 2.5-5 injections |
Cycling: Continuous use typical for maintenance, or 8-12 weeks intensive, 2-4 weeks off
• Intramuscular or subcutaneous injection • 2-3x weekly for general health and anti-aging • Can increase frequency for intensive protocols • Rotate injection sites to prevent irritation
GLUTATHIONE DOSING + CYCLING
IV Infusion Protocol (Clinical Setting - Most Bioavailable):
Glutathione | Saline/Fluid | Dose Range | Frequency | Duration |
Glutathione | 50-250mL | 600-2000mg | 1-3x weekly | 15-30 minutes |
Cycling: Weekly or bi-weekly infusions for maintenance or intensive detox protocols
• Must be administered in clinical setting • Rapid infusion over 15-30 minutes (unlike NAD+) • Higher doses for intensive detoxification • Most effective delivery method for immediate effects • Popular "push" method: 1200-2000mg rapid IV
ALTERNATIVE DELIVERY METHODS:
Oral Liposomal Glutathione: • 500-1000mg daily • Best absorbed oral form (liposomal encapsulation) • Take on empty stomach for optimal absorption • Less effective than injectable but convenient Apex Energetics Trizomal Glutathione
Oral Reduced Glutathione: • 500-1000mg daily • Poor bioavailability (significant breakdown in GI tract) • Requires consistent high doses • Most economical but least effective
Sublingual Glutathione: • 100-500mg daily • Better absorption than standard oral • Dissolve under tongue for 60-90 seconds • Moderate effectiveness
Topical/Nebulized Glutathione: • Specialized applications for specific conditions • Nebulized for respiratory conditions • Topical for localized skin benefits • Limited systemic absorption
GLUTATHIONE: SCREENING
Glutathione is generally very safe with minimal contraindications.
Screening Questions:
Are you pregnant or breastfeeding?
Do you have asthma or respiratory conditions?
Are you allergic to sulfur compounds?
Are you taking chemotherapy or immunosuppressive drugs?
Reasons: • Safety during pregnancy/breastfeeding not extensively studied • Nebulized glutathione may trigger asthma symptoms in sensitive individuals • Sulfur sensitivity may cause reactions • May interfere with certain cancer treatments (consult oncologist)
Note: Glutathione is extremely well-tolerated with very few side effects. Some individuals may experience mild nausea with IV administration or temporary lightheadedness. Injectable glutathione may cause slight discomfort at injection site. The master antioxidant effect makes it one of the safest and most beneficial supplements for overall health and longevity.
