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.[1] Supplementation with pyridoxine, folic acid, B12 or trimethylglycine (betaine) reduces the concentration of homocysteine in the bloodstream.[2]

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