Bruises are usually caused by bumping into something which ruptures the tiny capillaries under the skin leaving the area darkened. Some people bruise more easily than others, and this is indicative of fragile capillaries, poor health or an inability to create collagen. For people who bruise easily, bruises seem to appear for no apparent reason. Research has shown us that the leading cause of frequent bruising is a deficiency in one or more nutrients. The elderly, due to their generally poor diet, are quite susceptible to having bruises. The remedy is very simple: add supplements to your diet. Dieters who have lost a substantial amount of weight are also at risk of developing bruises. This is due to the fact that they have many capillaries that were needed to supply blood to their body, but that body is no longer there, leaving the capillaries exposed.
One of the main causes of bruising seems to be a deficiency in certain nutrients, primarily vitamin C, vitamin E, vitamin K, bioflavonoids, and zinc. A vitamin C deficiency may be caused by several factors:
Eating too few fruits and vegetables (remember the problem sailors used to have centuries ago with scurvy outbreaks on long voyages? It was caused by a lack of vitamin C)
Taking drugs which destroys this vitamin
Llong-time stress from illness, frustration or depression
Smoking (one cigarette can deplete the body of 25 mg of vitamin C)
Frequent emotional outbursts such as anger
Exposure to pollutants, allergens or heavy metals
A deficiency in hesperidin, one of the bioflavonoids (sometimes called vitamin P), naturally occurring nutrients usually found in association with vitamin C, has been linked with abnormal capillary weakness. These bioflavonoids, including hesperidin, Citrin, Rutin, Flavones, Flavonals, Calechin and Quercetin, were found to be essential in correcting the tendency toward bruising.
