Hyperhomocysteinemia

Hyperhomocysteinemia is a medical condition characterized by an abnormally large level of homocysteine in the blood.

As a consequence of the biochemical reactions in which homocysteine is involved, deficiencies of the vitamins folic acid, pyridoxine (B6), or B12 can lead to high homocysteine levels. Supplementation with pyridoxine, folic acid, B12 or trimethylglycine (betaine) reduces the concentration of homocysteine in the bloodstream.

Normal fasting homocysteine plasma levels are between 5,0 and 15,9 mmol/l.
