title: Link between higher levels of homocysteine and depression.
abstract: Homocysteine is an amino acid derived from methionine that is found in the diet, especially in animal protein. Homocystcinc is reconstituted into methionine, which is essential to the production of neurotransmitters such as serotonin and dopamine which elevate mood. This reconstitution requires B-group vitamins, especially folic acid and B12. High homocystcinc levels also have a toxic effect on neuronal cells, increasing psychiatric symptoms including depression. Previous studies have shown that nutritional supplements with B-group vitamins led to a reduction in symptoms of depression.
