Overview
What Is Glutathione?
Glutathione is a tripeptide composed of three amino acids: glutamate, cysteine, and glycine. It's one of the body's most abundant intracellular antioxidants.
Glutathione levels decline with age and are depleted by oxidative stress. Restoring it via injection or IV supports cellular antioxidant defense.
What It Does
What Patients Use Glutathione For.
Antioxidant Protection
Neutralizes reactive oxygen species at the cellular level.
Cellular Antioxidant Support
A cofactor for the body's antioxidant enzyme systems.
Immune Function
Glutathione is involved in normal T-cell function.
Mitochondrial Protection
Helps protect cells from oxidative damage.
Recovery Support
Supports clearance of exercise-induced oxidative stress.
Stack-friendly
Often paired with NAD+ in foundational longevity stacks.
Mechanism of Action
A Cellular Antioxidant Cofactor.
Glutathione donates electrons to neutralize reactive oxygen species — helping to limit oxidative damage to lipids, proteins, and DNA.
It's also a cofactor for the glutathione-S-transferase enzyme family, part of the body's normal cellular processing pathways.
Who It's For
Who Glutathione Is For.
Heavy Oxidative-stress Exposure
Patients managing high oxidative load from lifestyle or chronic stress.
Antioxidant Support
Patients seeking cellular antioxidant support.
Recovery Support
Athletes and high-output professionals managing chronic oxidative load.
Longevity Stacks
Often paired with NAD+ in foundational longevity stacks.
Research
The Evidence Base.
Glutathione is one of the most-studied molecules in human biology. Its role in oxidative stress and cellular antioxidant defense is well-characterized.
Therapeutic administration is supported by clinical research and broad practice.
503A-pharmacy compounded under USP-797 standards.
Dosing
Educational Only — Your Physician Sets the Protocol.
Glutathione can be given as a subcutaneous injection or an IV infusion. Oral glutathione has poor bioavailability. Your physician determines your dose, route, and protocol.
Protocol: continuous. Your physician sets the schedule.
Every protocol is reviewed and prescribed by a US-licensed physician. The information here is educational and not a substitute for clinical judgment.
FAQ
Common questions about Glutathione.
Oral glutathione has poor bioavailability — much of it is broken down in the gut before it's absorbed. Injection or IV bypasses that, producing more measurable effects.
