homocysteine
Cardiovascular risk marker
Homocysteine is an amino acid produced when the body breaks down proteins.
It's a normal intermediate in metabolism, but elevated blood levels are associated with increased risk of cardiovascular disease, blood clots, and stroke.
B vitamins—especially folate, B6, and B12—help convert homocysteine to other compounds, keeping levels in check.
