Simple homocysteine blood test to assess cardiovascular disease, osteoporosis, and Alzheimer's risk.
A homocysteine blood test measures the level of this amino acid in your blood. Homocysteine is a byproduct of protein metabolism that is normally converted into other useful substances with the help of vitamins B6, B12, and folate. When these vitamins are deficient or when genetic variants like MTHFR impair the conversion process, homocysteine can accumulate to harmful levels. Elevated homocysteine (hyperhomocysteinemia) is an independent risk factor for cardiovascular disease, stroke, blood clots, and cognitive decline. It is increasingly recognized in longevity medicine as a modifiable risk factor — levels can often be lowered through B-vitamin supplementation and dietary changes.
Key Details
Who Is This For?
Anyone with a family history of early heart disease or stroke. People with known MTHFR variants who need to monitor their methylation status. Health-conscious individuals incorporating cardiovascular risk markers into their longevity protocol. Those with B12 or folate deficiency being treated and monitored. People with a history of blood clots or recurrent miscarriage.
What's Included
Preparation Required
Fasting for 10–12 hours before the test is recommended for accurate results. Avoid B-vitamin supplements for 24 hours before testing unless you're specifically monitoring your treatment response.
Biomarkers Tested
1An amino acid produced during protein metabolism. Elevated homocysteine is an independent risk factor for cardiovascular disease, stroke, and cognitive decline. Levels are lowered by adequate B12, folate, and B6 intake.
