Glutathione is made up of three amino acids: glutamine, cystine, and glycine. It’s one of the body’s most powerful antioxidants. It works inside your cells to neutralize harmful “free radicals” and reactive oxygen species (ROS) — unstable molecules that can damage cells over time. It does this by donating electrons, which helps calm and stabilize these reactive compounds before they cause harm.
Glutathione also plays a major role in detox. It binds to toxins and chemicals in the body and makes them easier to flush out through urine or bile.
In addition, glutathione supports your immune system by helping activate and regulate immune cells, so your immune response stays balanced instead of over- or under-reacting.
Overall, glutathione helps protect your cells, supports repair processes, reduces inflammation, and keeps your body’s internal environment stable and healthy.
Glutathione may support a range of conditions where Glutathione levels are depleted due to high oxidative stress, systemic inflammation, or immune dysregulation, including: Alzheimer’s Disease, Parkinson’s Disease, Cardiovascular Disease, Chronic Fatigue Syndrome, Depression and anxiety disorders, Diabetes, Inflammatory Bowel Disease, Liver Disease, Multiple Sclerosis, Neuropathy, Rheumatoid Arthritis, Schizophrenia/Bipolar Disorders

What is glutathione?
Glutathione is a naturally occurring tripeptide composed of three amino acids: glutamine, cystine (cysteine), and glycine. It is produced within cells and is found throughout the body.What does glutathione do in the body?
Glutathione functions as a major intracellular antioxidant. It helps protect cells from oxidative stress by neutralizing free radicals and reactive oxygen species. It also plays a role in cellular detoxification processes.Why is glutathione considered important?
Glutathione is essential for maintaining cellular health. It supports normal immune function, helps regulate oxidative balance, and participates in enzymatic reactions involved in metabolism and detoxification.How does glutathione support detoxification?
Glutathione binds to certain toxins, heavy metals, and metabolic waste products in the liver through a process called conjugation. This allows these substances to become more water-soluble so they can be excreted from the body.Is glutathione naturally produced by the body?
Yes. The body makes glutathione from its three amino acid components. Production occurs primarily in the liver but also in other tissues.What can affect glutathione levels?
Levels may be influenced by aging, illness, oxidative stress, environmental exposures, poor nutrition, and certain medications. The body’s ability to make glutathione depends on adequate availability of its amino acid precursors.Is glutathione an antioxidant?
Yes. Glutathione is considered the “master antioxidant.” It’s one of the body’s most important antioxidants because it directly neutralizes free radicals and also helps regenerate other antioxidants, such as vitamins C and E.Are there side effects?
Glutathione is generally well tolerated. Please refer to the medication information linked on this page.Who should NOT use Glutathione?

Do sublingual lozenges and nasal sprays really work?
These delivery methods are well known in medicine.
Sublingual medications are absorbed through the oral mucosa under the tongue, and nasal sprays are absorbed through the nasal mucosa. These areas have rich blood vessel networks, which may allow medication to enter systemic circulation and bypass the gut.
These routes are widely used in healthcare. For example, medications such as sublingual nitroglycerin and intranasal naloxone use these pathways for rapid delivery.
While injectable medications often provide high bioavailability, sublingual tablets and nasal sprays offer a needle-free alternative.
Rely on Birdie for elevated needle-free options. No needles. Just progress.
