Two further meta-analyzes for Vitamin E showed that this increased the risk of haemorrhagic stroke by 22% and decreased the risk of ischemic stroke by 10%. In randomized studies, vitamin C, vitamin B, and folic acid have not been shown to have a protective effect in relation to stroke. However, there is a positive correlation between homocysteine level and stroke. For this reason, the use of folic acid and B vitamins is recommended for patients who have elevated levels of homocysteine. Frequently, vitamin B12 levels are lower in aged population, so the use of this vitamin is justified. Numerous studies have shown that low levels of vitamin D are associated with hypertension, atherosclerosis, and cardiovascular disease. The results suggest that a high intake of vitamin D (≥600 IU / day) is associated with a lower incidence of coronary heart disease and stroke in men, but not in women.
