Glutathione: Your Body's Master Antioxidant Explained

Glutathione is called the master antioxidant — not as a marketing term, but because it is literally the central molecule in your body's antioxidant and detoxification network. And most of us don't have nearly enough.

What Glutathione Actually Does

Glutathione (GSH) is a tripeptide made from three amino acids: glycine, cysteine, and glutamine. It's produced in virtually every cell of the human body, with the highest concentrations in the liver.

Its primary roles are: neutralizing reactive oxygen species (free radicals), regenerating other antioxidants like vitamins C and E, supporting Phase II liver detoxification, maintaining immune cell function, supporting mitochondrial energy production, and protecting DNA from oxidative damage.

Without adequate glutathione, oxidative stress accumulates. Cells age faster, detoxification pathways slow, immune function declines, and chronic inflammation sets in.

Why Glutathione Levels Drop

Glutathione depletion is extremely common. The main drivers include: UL:Chronic stress — cortisol depletes GSH|Poor diet — processed foods, low protein, low vegetables|Environmental toxins — pesticides, heavy metals, alcohol, medications|Chronic illness and infection|Aging — production naturally declines after age 20|MTHFR gene variants — affect methylation pathways required for GSH synthesis|Gut dysfunction — poor amino acid absorption limits precursor supply

Why Oral Glutathione Doesn't Work (Well)

Glutathione is a large, fragile molecule. When taken orally, it is largely broken down in the gut before it can be absorbed intact. Even the most expensive liposomal oral glutathione products achieve modest plasma increases compared to IV delivery.

IV glutathione bypasses the gut entirely, delivering the molecule directly to the bloodstream where it is immediately available to cells, tissues, and the liver.

Who Benefits Most from IV Glutathione

How It's Administered

At Full Circle Function, glutathione is available as an IV push (a rapid injection directly into the IV line at the end of an infusion) or as a standalone treatment. Most sessions take 5–15 minutes for the push. Results are often felt the same day — many patients report immediate clarity, better energy, and reduced inflammation.

Frequently Asked Questions

Glutathione is a tripeptide antioxidant produced in every cell of the body. It neutralizes free radicals, supports liver detoxification, protects DNA, regenerates other antioxidants, and supports immune function.

Oral glutathione is largely broken down in the gut before absorption. IV glutathione bypasses digestion and delivers the molecule directly to the bloodstream for immediate cellular availability.

Many people report feeling clearer, more energized, and less inflamed after IV glutathione. Some notice improved skin tone over several sessions. Effects vary by individual health status.

Yes. IV glutathione is well-tolerated and has been used clinically for decades. It is administered by trained medical professionals at Full Circle Function under the supervision of Laura Burton, NP.
