What is Glutathione?

The body's master antioxidant tripeptide, used in research for redox support and detoxification pathways.

How it works

Directly scavenges reactive oxygen species and serves as cofactor for glutathione peroxidase and transferase detoxification enzymes; injectable forms bypass poor oral absorption.

What it has been studied for

Powerful antioxidant defense
Supports liver detoxification
May enhance immune function
Supports skin clarity and brightness

These are effects reported or investigated in research, much of it preclinical. They are not proven outcomes or health claims.

Published research

Extensive biochemistry literature; clinical injectable data mostly small and uncontrolled

Half-life

~2 minutes IV (very rapid; minutes)

Cautions

Generally well tolerated; inhaled forms can trigger bronchospasm in asthmatics.

Side effects & fixes

Common side effects

—Human side-effect data is limited or absent for this compound
—Injection-site redness, itching or soreness is the most commonly reported effect for injected research peptides

Histamine reactions

Possible at the injection site, as with most injected peptides.

Common fixes

Rotate injection sites (abdomen, thighs, upper arms) and stay at least an inch from the last spot.
Let the alcohol swab dry fully, let the solution reach room temperature, and inject slowly with a fresh needle.
A cold compress for 5–10 minutes eases a red or itchy welt; it should fade within a day.
For mild itching, redness or flushing, a non-drowsy over-the-counter antihistamine (such as cetirizine or loratadine) is commonly used — check with a pharmacist first, especially if you take other medicines.
Start low, change one thing at a time, and keep a log of how you feel.

Stop and get help

Any unexpected or severe symptom — stop and contact a doctor.
Stop and get emergency help for swelling of the face, lips, tongue or throat, trouble breathing, widespread hives, chest pain or fainting.

Basis: Limited data; general experience with injected peptides. Educational only, not medical advice.

Medication concerns

Theoretical: no human interaction studies

Chemotherapy and radiation
As an antioxidant, glutathione may interfere with some cancer treatments that work through oxidative stress. Ask the oncology team.
Inhaled glutathione with asthma
Can trigger airway narrowing in some people with asthma.
Everything else you take, including supplements
Bring a full list of medicines and supplements to your pharmacist or clinician before starting.

Basis: Limited human data; concerns from its antioxidant role and reported reactions. Educational only, not medical advice. Never stop or change a prescribed medicine without your prescriber.
