Homocysteine-lowering trials for prevention of heart disease and stroke.
Dietary supplementation with B-vitamins that lower plasma total homocysteine concentrations are expected to lower the risk of cardiovascular disease. Folic acid and vitamin B (12) lower blood homocysteine concentrations by about 25-30% in populations without folic acid fortification, but by only 10-15% in populations with fortification. In observational studies, 25% lower homocysteine is associated with about 10% less coronary heart disease (CHD) and about 20% less stroke. This review examine...Expand abstract
