IV Glutathione – the Master Antioxidant




Have you ever received Intravenous Nutrient Therapy (IVNT) in a Naturopathic Doctor’s office? The most common IVNT offered is a Myers’ cocktail (please refer to the clinic’s Instagram page and Dr. McKinnon’s previous blog to learn more about these). Another common treatment option is Intravenous Glutathione, which is one of the best antioxidants for our health.


Glutathione is a tripeptide made from three amino acids: glycine, glutamine, and cysteine. These can be found in our diet or as supplements, which help produce glutathione in our bodies. This is one of the most important antioxidants! It has multiple health-supportive roles and is found in every cell in our body.


Glutathione decreases as we age, therefore, it may be helpful to supplement. It has been shown to be one of the strongest anti-cancer agents produced by the body.


Main functions of Glutathione:

  1. Reduces cellular damage (great for slowing the aging process!)

  2. Improves detoxification pathways

  3. Protects mitochondria (energy-producing factories in every cell in our body!)

  4. Can help manage toxins and some heavy metals

  5. Improves cognition (great for the brain!)

  6. Improves skin complexion and acne

  7. Can decrease free radicals (which can lead to disease)


Glutathione supports the following organs and systems:

  1. Liver

  2. Lungs

  3. Skin

  4. Metabolic system

  5. Brain and neurological system

  6. Immune system

  7. Digestive system


Supplemental Forms of Glutathione:

  1. It is an unstable molecule and can be challenging to absorb orally as a supplement.

  2. The ideal oral supplement is found in a form called “liposomal”, which is a more stable form than other oral glutathione supplements.

  3. The ideal form is intravenous (IV) glutathione as it is found in its whole form.

  • IV Glutathione therapy bypasses the digestive tract entirely, which is great for its delivery to cells.

  • Glutathione is administered alone and cannot be mixed with other nutrients.

  • To get the maximum benefits of IV glutathione, it is best to be taken with supportive nutrients such as vitamin C and selenium.


Glutathione Testing Options:

  • Intracellular levels via micronutrient blood panel offered at the clinic.

  • Breakdown product of pyroglutamate measured on dried urine hormone test offered at the clinic.


Glutathione is a wonderful antioxidant! I often talk about this key nutrient with my patients as it plays such a vital role in our health.
