Q. I bruise easily. Does this mean I’m deficient in some nutrient?
A. Bruising easily is rarely a sign of nutrient deficiency. Bruises are created when the tissue just under the skin gets injured, resulting in a buildup of blood that causes the skin to turn black and blue. Sometimes easy bruising runs in families. And women are more likely to bruise from a minor injury, especially on the thighs, buttocks, and upper arms. It is also common for older adults to bruise easily as capillaries age and the skin’s protective layers become thinner. Although uncommon, vitamin C deficiency can sometimes result in a heightened susceptibility to bruising.
Increased bruising may be a side effect of certain medications that thin the skin or interfere with the blood’s ability to clot, such as steroids, cortisone drugs, aspirin, or ibuprofen. It is also thought that some dietary supplements, including vitamin E, fish oil, ginger, garlic, and ginkgo—which can have similar effects on the blood and skin—may augment bruising. However, the health benefits of these medications and supplements are probably worth a little extra bruising, so consult with your health care practitioner before discontinuing them.
If you are concerned about how easily you bruise, try increasing your intake of the bioflavonoid compounds found in plant foods, such as citrus fruits and berries, which can potentially reduce bruising by strengthening capillary walls and the surrounding connective tissue. If bruises don’t seem to be healing normally, visit your health care practitioner to evaluate the cause and discuss treatment.
