@shelli3300 I don't believe you will find a CLL specialist at Mayo that would recommend this approach, but I'm glad she is well. There is no data which shows Vitamin C supplementation treats CLL and there is some evidence glutathione may actually support CLL cell survival.

From Grok AI.
Question: Can Glutathione treat CLL?

No. Glutathione does not treat CLL, and raising it is not a therapeutic strategy.
CLL cells are under high oxidative stress and rely on glutathione (GSH) to survive, resist apoptosis, and maintain drug resistance. In the body they depend on bone marrow stromal cells to supply the cysteine they need for GSH synthesis (they have limited ability to take up cystine themselves). Higher GSH levels protect the leukemia cells; depleting GSH (for example with PEITC in lab studies) kills them and overcomes stromal protection.

CLL patients should seek the care and consultation of a CLL specialist. Even general oncologists often struggle to fully understand this disease and keep up with the latest research and I would certainly not rely on a Naturopath.
