Homocysteine is an amino acid. Vitamins B12, B6 and folate break down homocysteine to create other chemicals your body needs. High homocysteine levels may mean you have a vitamin deficiency. Without treatment, elevated homocysteine increases your risks for dementia, heart disease and stroke.

Homocysteine is an amino acid. Vitamins B12, B6 and folate interact with homocysteine and create other proteins that your body needs. Typically, very little homocysteine stays in your blood. High homocysteine levels could mean you have an underlying condition such as heart disease or homocystinuria. Your healthcare provider may order a homocysteine blood test. Based on the test results, your healthcare provider can recommend the best treatment option.
