Homocysteine Index

Featured: Homocysteine (Normal and Elevated Levels Blood Test) Main Article

Elevated homocysteine levels (hyperhomocysteinemia) is a sign that the body isn't producing enough of the amino acid homocysteine. The condition may be genetic (inherited) called homocystinuria. Homocystinuria is a somewhat rare genetic (inherited) condition that includes symptoms like developmental delays, osteoporosis, blood clots, heart attack, heart disease, stroke, and visual abnormalities died at an early age. There are other causes of the condition like alcoholism.

Supplementing the diet with folic acid and possibly vitamins B6 and B12 supplements can lower homocysteine levels. Currently there is no direct proof that taking folic acid and B vitamins to lower homocysteine levels prevent heart attacks and strokes. Talk to your doctor if you feel you need to have your homocysteine blood levels checked.
