high-dose B vitamins are NOT beneficial for patients with heart disease
More evidence suggests that high-dose B vitamins are NOT beneficial for patients with heart disease.
We know that homocysteine levels are often elevated in patients with heart disease. And these levels can be lowered with high doses of folic acid, pyridoxine, and B12.
But we DON'T know if using these vitamins to lower homocysteine actually prevents cardiovascular events. The big question is whether homocysteine is just a MARKER...or an actual CAUSE...of heart disease.
