The Claim
Vitamin C increases the labile iron pool in human fibroblasts by promoting the reduction of ferric iron to ferrous iron, facilitating Fenton chemistry under oxidative conditions.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Vitamin C increases the amount of reactive iron inside human fibroblast cells by converting ferric iron to ferrous iron, which enhances Fenton chemistry under oxidative conditions.
See the scientific wording
Vitamin C increases the labile iron pool in human fibroblasts by promoting the reduction of ferric iron to ferrous iron, facilitating Fenton chemistry under oxidative conditions.
Vitamin C converts stored iron into a more reactive form that reacts with hydrogen peroxide to produce highly damaging molecules, which break DNA and kill cells when oxygen stress is present.
What the research says
1 studyStudy: Vitamin C modulation of H2O2-induced damage and iron homeostasis in human cells.
Vitamin C doesn’t just protect cells — in the presence of hydrogen peroxide, it helps turn stored iron into a more reactive form that makes damaging chemicals, hurting cells more. The study showed this happens in human skin cells.
