About this biomarker
Homocysteine is an amino acid made during methionine metabolism. Its level can be influenced by folate, vitamin B12, vitamin B6, genetics, and kidney function.
Why it matters
It can add context to nutrition-related pathways and cardiovascular risk patterns.
What lower levels may suggest
Low homocysteine is usually not a major concern on its own.
What higher levels may suggest
High homocysteine may be seen with low folate or B12, kidney dysfunction, inherited metabolism differences, or other causes.
