Easy Bruising

Vitamin C helps in the production of collagen, a protein that helps maintain your blood vessels healthy. You may find that you bruise easily if you don't receive enough vitamin C in your diet. While low vitamin C levels are uncommon, it is more likely if you smoke.

When blood vessels under the skin rupture, blood leaks into the surrounding areas, causing bruising. Because poor collagen production causes weak blood vessels, easy bruising is a typical indication of vitamin C deficiency. Bruises caused by deficiency might cover large areas of the body or appear as small purple patches beneath the skin. As a result, one of the first obvious symptoms of a deficiency is easy bruising.
