What a high Vitamin C (ascorbic acid) can mean

  • Supplementation — the usual reason; vitamin C is water-soluble and excess is largely excreted.
  • Very high intakes — occasionally linked to kidney stones in susceptible people, and can affect some lab tests.

When to discuss with a doctor

Vitamin C is not a routine test, but it is worth considering when there are suggestive features — bleeding or swollen gums, easy bruising, poor wound healing and tiredness — especially in someone at risk from a very poor diet, alcohol excess, smoking or an eating disorder. Recognising scurvy is rewarding because it corrects quickly with vitamin C replacement and a better diet. In practice, treatment is often started on the clinical picture. Because vitamin C also aids iron absorption, it is sometimes relevant in iron-deficiency situations. Mediora.AI shows vitamin C with related nutritional markers so the picture is read together; the interpretation and any treatment belong with your doctor.
