Glutathione

Glutathione is a tripeptide (glutamate-cysteine-glycine) produced in every cell. It functions as the body's primary endogenous antioxidant — neutralizing reactive oxygen species, regenerating vitamins C and E, and serving as the main substrate for Phase II liver detoxification. Levels decline with age, illness, and environmental toxin exposure.

Oral glutathione has poor bioavailability — it is largely broken down in the GI tract before reaching systemic circulation. Injectable and IV forms bypass this problem entirely, delivering glutathione directly into the bloodstream. Buccal (sublingual) strips offer a middle ground with better absorption than oral capsules. IV infusion protocols in clinical settings typically use 600–1200 mg per session.

Common research protocols use 200–600 mg administered subcutaneously or intramuscularly 2–3 times per week. IV infusion clinics typically administer 600–1200 mg per session, often as part of a "Myers cocktail" or standalone push. Protocols generally run 8 weeks on, 4 weeks off, though some clinical applications use continuous dosing.

Injectable glutathione is generally well-tolerated. Reported side effects are uncommon and typically mild — injection site discomfort, occasional bloating, or rare allergic reactions. IV glutathione at high doses may cause transient cramping. Long-term safety data for injectable glutathione supplementation remains limited compared to its extensive IV clinical use.

Improved energy and recovery are commonly reported within 2–4 weeks of consistent injectable use. Skin brightening and more even tone typically emerge at 4–8 weeks. Immune resilience improvements may take 6–8 weeks to become apparent. IV infusion users often report immediate energy and clarity benefits within hours of a session.

Yes, glutathione and NAD+ are frequently combined in longevity and anti-aging protocols. The rationale is complementary — NAD+ restores cellular energy and sirtuin-mediated DNA repair, while glutathione handles oxidative stress reduction and detoxification. Some IV clinics administer both in the same session. No negative interactions have been reported in research literature.

Once mixed with bacteriostatic water, peptides remain stable for up to 4 weeks when refrigerated at 2-8°C (36-46°F). Unopened powder can last 1+ year in the freezer. Get our complete Storage & Travel Guide.

Peptides sold "for research purposes only" are legal to purchase in the US, but are not FDA-approved for human use outside of specific medical applications. Always consult a healthcare provider before use.
