Testing and Treatments to Raise Glutathione Blood Levels in Clinical Practice

Tuesday, December 5, 2023 | (Recorded)
Free Sponsored On-demand Webinar

Until now, you couldn’t depend on oral glutathione supplements to boost blood and tissue levels because they were easily broken down and not always well-absorbed.1-4 We will discuss a revolutionary delivery system that increases glutathione absorption 2.5 times more than the leading oral glutathione supplement. From neurodegenerative disorders, to lung disease, aging, detoxification, and more, glutathione is vital for the health of every cell. You will learn the types of patients in your clinic that may benefit most from glutathione support. After this webinar, you will know the urine and blood tests to determine a patient’s glutathione status, genetic susceptibility, and oxidation-reduction balance. With this information, you can customize a glutathione treatment protocol and monitor patient progress. Practitioners have been wanting an effective oral glutathione product for their most complicated patients and now it’s here.
