Can a homocystine level of 55 cause damage to endothelial cells?

This high level of homocysteine has been associated with increased risk of cardiovascular events. Treatment with methylated folic acid (sometimes requiring doses of 5-15mg/day) might reduce homocysteine to normal levels, but there is no study showing a reduced risk if homocysteine is reduced to normal. If one considers treatment with methylated folic acid, they should first consult their Dr.
