Commentary: Vitamin C: Antioxidant or Pro-Oxidant In Vivo?

Halliwell, Barry·1996·Free Radical Research

Abstract

Ascorbic acid has a multiplicity of antioxidant properties, but it can exert pro-oxidant effects in vitro, usually by interaction with transition metal ions. It is as yet uncertain that these pro-oxidant effects have any biological relevance: some of the available data are summarized.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Prooxidant properties of vitamin C in the presence of redox-active metal ions and oxygen have been confirmed predominantly under in vitro conditions; occurrence under in vivo conditions has not been convincingly documented.

    “Prooxidant properties of vitamin C in the presence of redox-active metal ions and oxygen have been confirmed predominantly under in vitro conditions, occurrence under in vivo conditions has not been convincingly documented (Halliwell 1996).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
