Does vitamin C help with bruising?
By Margaret Hale, Reunoa EditorialLast updated
The short answer
Vitamin C helps bruising mainly if you're low in it. It's essential for building collagen in skin and blood vessel walls, and deficiency causes easy bruising, bleeding gums and slow wound healing. Older adults who eat poorly are most at risk. If your levels are normal, extra vitamin C pills are unlikely to stop bruises. Topical vitamin C can improve photoaged skin over months.
Vitamin C often comes up when people ask what to take for easy bruising. It has a real role — but a specific one.
What vitamin C does for skin and vessels
Vitamin C is needed to build collagen, the protein that supports skin and the walls of small blood vessels. MedlinePlus lists easy bruising, bleeding gums, nosebleeds and slow wound healing among signs of deficiency [1]. Severe deficiency is scurvy [2].
Who is low in vitamin C?
- In the 2003–2004 US national survey, about 7% of people were vitamin C deficient; smokers had much lower levels [4].
- In a French study of hospitalized elderly patients, 12% had clinical signs of scurvy, and nearly all of them had low vitamin C levels; needing help with eating was more common in that group [3].
- In a US case series, bruising was among the most common symptoms of scurvy; poor diet, dental problems and alcohol were common contributors [5].
Risk factors: few fruits and vegetables, eating alone, poor teeth or dentures, alcohol, smoking, gut disease.
Does extra vitamin C prevent bruising?
If you're deficient, correcting it can reduce bruising and help wounds heal. If your levels are normal, there's no good evidence that extra vitamin C pills reduce everyday bruising or senile purpura.
A related option has better purpura-specific evidence: a citrus bioflavonoid supplement (plant compounds found alongside vitamin C in citrus) reduced new purpura lesions by 50% in a six-week placebo-controlled trial [7].
Topical vitamin C
Topical vitamin C serums are popular for aging skin. A systematic review found topical vitamin C made photoaged skin smoother and less wrinkled and lightened pigmentation [6]. It hasn't been tested on bruising, but supporting collagen in sun-damaged skin is plausible as part of a routine.
How to get enough
| Food | Approx. vitamin C |
|---|---|
| 1 orange | ~70 mg |
| 1 kiwi | ~65 mg |
| ½ cup red pepper | ~95 mg |
| ½ cup broccoli | ~50 mg |
| ½ cup strawberries | ~45 mg |
Adults need about 75–90 mg a day; smokers need more. A daily serving or two of fruit and vegetables covers it. MedlinePlus notes doses above 2,000 mg/day aren't recommended [1].
Vitamin C and blood thinners
Vitamin C from food or standard supplements doesn't interfere with blood thinners like Eliquis or Xarelto. People on warfarin should mention any new supplement to their anticoagulation clinic, as a general rule. Very high doses aren't recommended for anyone.
Frequently asked questions
Does vitamin C help bruises heal faster?
If you're low in vitamin C, correcting it supports collagen and healing. Extra vitamin C on top of normal levels hasn't been shown to speed bruise healing.
How much vitamin C should I take for bruising?
Most adults need 75–90 mg a day, easily reached with fruit and vegetables. Ask your doctor before high-dose supplements.
Is vitamin C cream good for bruises?
Topical vitamin C improves photoaged skin over months. There's no direct evidence it fades bruises.
What deficiency causes easy bruising in the elderly?
Most often vitamin C, sometimes vitamin K. Both are more likely with a poor diet, gut problems or alcohol.
