It protects cells against free radicals, peroxides, and heavy metals while eliminating toxins including drugs and pollutants. Injectable glutathione bypasses gastrointestinal breakdown for superior bioavailability compared to oral supplements. Research supports benefits for neurological health, immune function, skin health, and anti-aging. ### Mechanism of Action Glutathione acts as the primary intracellular antioxidant, directly neutralizing reactive oxygen species and regenerating other antioxidants like vitamins C and E. It plays crucial roles in detoxification by conjugating with toxins for elimination, supports immune function through T-cell regulation, protects mitochondria, and maintains cellular redox balance. The thiol group of cysteine provides its antioxidant activity. ### Key Benefits - Master antioxidant - protects against oxidative stress - Detoxification of heavy metals and toxins - Immune system support and T-cell function - Neuroprotective effects - Skin health and potential brightening effects - Liver protection and function - Mitochondrial support - Anti-aging properties ### Quick Stats Typical Dose 100-600 mg injectable (100-200mg wellness, 200-600mg intensive); IV dosing higher (600-1400mg clinical) Frequency 2-3 times weekly for subcutaneous; weekly for IV infusions Cycle Duration 8-12 weeks Storage Lyophilized: 2-8°C refrigerated, protect from light; Reconstituted: 2-8°C refrigerated, protect from light ## Molecular Information Molecular Weight 307.32 Da Length 3 amino acids Type Tripeptide Half-Life ~10-14 minutes (IV) ### Amino Acid Sequence One-letter: `?ECG` γ 1 γ Position 1 Glu 2 Glutamic Acid Position 2 Cys 3 Cysteine Position 3 Gly 4 Glycine Position 4 N-terminus C-terminus Hydrophobic Polar Positive (+) Negative (-) Modified ## Research Indications The following information is derived from published scientific literature and is provided for educational and research reference purposes only. It does not constitute medical advice, diagnosis, or treatment recommendations. These peptides are not approved for human use and are sold exclusively for in-vitro laboratory research. Antioxidant & Detox Neurological Immune & Skin ## Dosing Protocols ### injectable Injectable glutathione is the most effective delivery method, bypassing GI breakdown for direct absorption. Subcutaneous injections are typically administered 2-3 times weekly. IV administration is fastest-acting but requires clinical supervision. Start with lower doses to assess tolerance. | Goal | Dose | Frequency | Route | | --- | --- | --- | --- | | General wellness | 100-200 mg | 2-3x weekly | SubQ | | Intensive therapy | 200-600 mg | 2-3x weekly | SubQ or IV | | Detoxification | 600-1000 mg | Weekly IV | IV (clinical) | | Parkinson's support | 1400 mg | 2-3x weekly | IV (clinical) | #### Key Tips - Bypasses GI degradation - Superior bioavailability - Direct cellular uptake - Faster onset than oral Reconstitution Instructions ### oral Oral glutathione has poor bioavailability due to GI breakdown. Liposomal formulations may offer improved absorption but are still less effective than injection. | Goal | Dose | Frequency | Route | | --- | --- | --- | --- | | Daily supplementation | 250-1000 mg | Daily | Oral | #### Key Tips - Convenient - Non-invasive - Liposomal forms have better absorption ## Peptide Interactions #### NAD+ Synergistic Both support cellular energy and antioxidant systems; commonly combined in longevity protocols. #### Vitamin C Synergistic Glutathione regenerates oxidized vitamin C, creating synergistic antioxidant effects. #### SS-31 Synergistic Both protect mitochondria; different mechanisms complement each other. #### BPC-157 Compatible No known negative interactions. ## What to Expect Immediately Antioxidant activity begins Days-Week 1 Improved energy and well-being may be noticed Week 2-4 Cumulative detoxification benefits Week 4-12 Full benefits for skin, immunity, and cellular health ## Side Effects & Safety #### Common Side Effects - Injection site reactions - Mild nausea (usually with higher doses) - Abdominal cramping #### Monitoring - Consider zinc supplementation with long-term use - IV administration requires clinical supervision #### Stop Signs - Signs of allergic reaction (rash, difficulty breathing) - Severe abdominal pain - Signs of zinc deficiency #### Contraindications - Known allergy to glutathione - Pregnancy or breastfeeding (insufficient safety data) - Asthma (may trigger bronchospasm in some) ## Quality Checklist #### Good Signs - White to off-white lyophilized powder - Clear solution after reconstitution - Reduced (not oxidized) form - Intact vacuum seal #### Warning Signs - Slight yellowing may indicate oxidation #### Bad Signs - Dark yellow or brown coloration - Cloudy solution - Strong sulfur odor (beyond mild) ## Research & References ### Key References 1. 2009 #### IV Glutathione in Parkinson's Disease Movement Disorders IV glutathione 1,400 mg 3x weekly showed possible mild symptomatic effect in small trial. 2. 2019 #### Liposomal Glutathione in HIV Patients European Journal of Clinical Nutrition 13-week supplementation improved Th1 cytokines including IL-12, IFN-γ, and TNF-α. 3. 2025 #### Glutathione Supplementation for Skin Lightening Dermatology Reports Narrative review of efficacy and safety for skin lightening applications. 4. 2018 #### Glutathione Metabolism and Function Annual Review of Nutrition Comprehensive review of glutathione as master antioxidant and its roles in health.
