Homocysteine

Measured in umol/L

An amino acid that damages blood vessel linings when it accumulates. Usually a vitamin problem, and usually fixable.

What the numbers mean

These are the ranges BioForge works to. They are not the same as a lab's reference range, which is built from the general population rather than from people who feel well.

Low
<5
Optimal
6–9
High
>12

What moves Homocysteine

Driven up by low B12, folate or B6, MTHFR gene variants, kidney disease, smoking, and heavy coffee or alcohol. Usually responds well to methylated B vitamins.
