Homocysteine

What it tests for:
Homocysteine is an amino acid in the blood that, when elevated, can increase your risk of cardiovascular disease, stroke, and cognitive decline. This test helps assess your methylation function and B-vitamin status, particularly B6, B12, and folate.

Why it matters:

• High levels are associated with inflammation, blood vessel damage, and heart disease risk

• May play a role in brain health, mood regulation, and detoxification pathways

• Useful for identifying nutritional deficiencies that can be corrected through targeted supplementation

Who it’s for:
Recommended for individuals with a family history of heart disease, unexplained fatigue, mood disorders, or those optimizing for longevity, brain function, or methylation support.
