This study looked at whether high-dose vitamin C given through an IV might help people with Epstein-Barr virus (EBV) infection, including those with ME/CFS. Researchers reviewed medical records of 178 patients who received vitamin C infusions and had elevated EBV antibodies. They found that patients who received these treatments showed lower levels of EBV antibodies over time, and that higher vitamin C levels in the blood were associated with lower viral markers.
Since many ME/CFS patients have elevated EBV antibodies and persistent viral reactivation may contribute to symptoms, understanding whether nutrient interventions could modulate viral load is clinically relevant. This study provides preliminary evidence that warrants further controlled investigation into high-dose vitamin C as a potential supportive therapy for EBV-associated fatigue.
This study does not prove that high-dose vitamin C causes EBV antibody reduction, only that an association was observed in treated patients. Without a control group receiving standard care or placebo, it is impossible to determine whether improvements were due to vitamin C, spontaneous recovery, other concurrent treatments, or patient selection bias. The retrospective design and lack of standardized protocols also limit causal inference.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
