    Vitamin C for Bruising Easily

    Severe vitamin C deficiency (scurvy) genuinely causes easy bruising, and repletion fixes it dramatically — but true scurvy is rare, and supplementing when levels are normal does nothing for bruising.

    Overview

    Severe vitamin C deficiency (scurvy) genuinely causes easy bruising, and repletion fixes it dramatically — but true scurvy is rare, and supplementing when levels are normal does nothing for bruising.

    Verdict

    Mixed evidence

    How It Works

    Vitamin C is required for collagen hydroxylation; without it, capillary walls and perivascular connective tissue weaken, producing perifollicular hemorrhage and easy bruising.

    Dosing & Protocol

    Typical dose

    Recommended dose
    500 mg vitamin C daily with food; deficiency is corrected with 100-300 mg/day
    Expected timeframe
    2-4 weeks in deficiency; no effect expected if replete

    Protocol

    form
    Ascorbic acid, or a buffered form such as sodium ascorbate if plain ascorbic acid upsets your stomach
    duration
    4-8 weeks; frank scurvy improves within days to weeks
    co factor
    Take with food. Evidence is mixed and depends entirely on status: vitamin C deficiency causes capillary fragility and perifollicular haemorrhage, and correcting it resolves the bruising quickly and dramatically. In people who are already replete, supplementation does nothing for bruising.
    titration
    No escalation needed - absorption falls sharply above 500 mg per dose, so splitting is better than increasing
    starting dose
    500 mg vitamin C once daily with food

    Evidence

    What the studies say

    The deficiency link is textbook-strong and reversal is rapid with repletion. But scurvy is uncommon outside of very restricted diets, alcohol use disorder, or severe eating disorders. No evidence supports vitamin C for bruising in people with adequate intake. Unexplained bruising with bleeding gums, nosebleeds, or petechiae warrants a CBC and clotting workup — low platelets and leukemia can present this way.

    Safety

    Caveats

    Easy bruising is a symptom that needs a cause. Get a full blood count and clotting screen: thrombocytopenia, leukaemia, liver disease, von Willebrand disease and anticoagulant effects all present this way, as does long-term corticosteroid use and simple ageing skin. Bruising with bleeding gums, nosebleeds, heavy periods or petechiae needs prompt assessment. Unexplained bruising in a child warrants safeguarding consideration. Safety ceiling: the tolerable upper intake level is 2000 mg/day; above that causes diarrhoea and raises oxalate kidney stone risk. Avoid high doses in haemochromatosis and G6PD deficiency (haemolysis risk), and in kidney disease. Vitamin C interferes with some glucose meters. Safe in pregnancy at normal doses.

    Less likely to help if

    People who are already vitamin C replete, and those bruising from platelet, clotting or medication causes.
