Intravenous Vitamin C and Quality of Life in Breast Cancer Patients
Intravenous Vitamin C and Quality of Life in Breast Cancer Patients
Supportive therapies that reduce treatment-related side effects and improve quality of life are an important focus in breast cancer care. Vollbracht and colleagues evaluated the impact of intravenous vitamin C on symptom burden and overall well-being in patients undergoing chemotherapy, radiotherapy, and follow-up care.
This retrospective, multicentre cohort study in Germany included several hundred breast cancer patients who received standard oncologic therapy, with a subset also receiving adjunctive intravenous vitamin C. The vitamin C group received repeated infusions (commonly 7.5 g per infusion) administered one to three times per week during active treatment and, in some cases, continued into the aftercare phase. Outcomes were assessed using physician-documented and patient-reported measures of common therapy-related symptoms, including fatigue, nausea, depression, sleep disturbances, and functional impairment.
The investigators reported that patients receiving intravenous vitamin C experienced statistically significant reductions in several key symptoms compared with the control group. Improvements were particularly notable in fatigue, nausea, appetite loss, sleep disorders, and overall performance status. These benefits were observed both during chemotherapy and radiotherapy and persisted into the post-treatment period. The treatment was well tolerated, with no serious adverse effects attributed to vitamin C administration reported in the cohort.
Although the retrospective design limits causal interpretation and introduces the possibility of selection bias, the consistency of symptom improvement across multiple domains supports the use of adjunctive intravenous vitamin C in breast cancer care. These findings support further investigation through prospective randomized trials to better define efficacy, optimal dosing, and patient selection.
