Homocysteine is an amino acid produced by the body.
Elevated homocysteine levels are linked to high concentrations of endothelial asymmetric dimethylarginine (ADMA); a chemical found in blood plasma. ADMA interferes with the synthesization of Nitric Oxide from L-Arginine. Nitric Oxide is important in our bodies because it increases blood flow. (Click here to read more on the role of Arginine and Nitric Oxide in our bodies)
It is important for Osteonecrosis (Avascular Necrosis) sufferers to have their homocysteine levels checked because high homocysteine levels cause narrowing of the arteries and can lead to excessive blood clotting.
Vitamins B6, B12 and Folic acid are commonly taken to lower homocysteine levels.

Hi, Thank you so much for creating this website that helps so many people from all over the world. I have tried to contact Dr Glueck to get some advice however I now know he has retired. I would like to know more about what tests to do for AVN and find someone who can interpret the results. Do you know any other US based Dr that knows about AVN like Dr Glueck? I live in Australia, and I have not found a Dr here. Are you able to possibly contact me?
