Vitamin C (ascorbic acid) is an essential water-soluble antioxidant and enzyme cofactor. Humans cannot synthesise it; daily intake is required. At high doses (≥500 mg) it transitions from an antioxidant to a pro-oxidant in tumour tissues — an area of active oncology research. Its roles span collagen synthesis, iron absorption, immune function, and neutralising free radicals.
