Vitamin C may reduce stroke risk

Published on

According to a new study from France increased intakes of vitamin C may reduce the risk of developing hemorrhagic stroke.

The observational study compared blood vitamin C concentrations of 65 patients who had experienced an intracerebral hemorrhagic stroke with blood levels of 65 healthy participants (1). The study results showed that 41% of the participants had sufficient levels of vitamin C, 45% showed insufficient levels and 14% were considered vitamin C deficient. On average, the participants who had suffered a stroke had significantly lower levels of vitamin C, while those who had not had a stroke had normal levels of the vitamin.

The researchers commented that results of the study show that vitamin C deficiency should be considered a risk factor for this severe type of stroke, along with high blood pressure, drinking alcohol and being over- weight. Hemorrhagic stroke, or a blood vessel rupture inside the brain, is less common than ischemic stroke, but can often prove to be more fatal. More research is needed to explore specifically how vitamin C may help to reduce stroke risk. For example, the vitamin may regulate blood pressure. Vitamin C deficiency has also been linked to coronary heart disease (2).
