The Role of Glutathione in Cancer Supportive Therapy
Helping you understand “what glutathione supplementation can actually do”
Glutathione (GSH) is one of the body’s most important endogenous antioxidants and is widely used in cancer supportive care.
It not only helps reduce treatment-related side effects but also improves fatigue, protects vital organs, and in some cases enhances treatment tolerance.
Below are the most commonly observed benefits from current clinical research and practice.
How glutathione commonly supports patients during cancer treatment
- Reduces chemotherapy toxicity: particularly kidney, nerve, and heart damage caused by drugs like cisplatin, doxorubicin, and paclitaxel
- Improves chemotherapy-related fatigue: enhances mitochondrial function for more efficient energy production
- Protects liver and kidney function: lightens the metabolic burden, helping maintain normal organ indices
- Alleviates radiotherapy side effects: decreases the severity of radiation-induced mucositis, skin damage, and oral ulcers
- Supports the immune system: protects immune cells from oxidative damage, helping sustain NK-cell and T-cell activity
Why glutathione is considered helpful in cancer patients
- Chemotherapy and radiotherapy massively increase oxidative stress; glutathione, as the “master antioxidant”, rapidly neutralises free radicals
- Treatment often causes mitochondrial dysfunction; glutathione directly supplies electrons to restore energy metabolism
- Many chemotherapy drugs deplete glutathione, leading to endogenous deficiency; supplementation helps replenish stores
- Clinical studies show glutathione does not promote tumour growth and may indirectly improve treatment sensitivity (e.g., reducing drug resistance)
Common administration methods
(always determined by the physician based on individual condition)
- Intravenous infusion: the most common route, with near-100% absorption
- Typically 1–3 sessions per week; dosage and frequency adjusted by weight, treatment stage, and blood results
- Often combined with vitamin C, alpha-lipoic acid (ALA), or amino acids for enhanced antioxidant and energy support
- Liver/kidney function and tumour markers are monitored before and after to ensure safety
Summary
Glutathione’s role in cancer supportive therapy is to “protect normal tissues” rather than “attack the tumour”.
It allows patients to experience fewer side effects, better energy, and higher quality of life during active treatment.
When the body’s antioxidant system is well supported, the cancer-fighting process becomes smoother and more comfortable.
