Homocysteine is a signal
Elevated homocysteine can point toward methylation strain, B-vitamin demand, oxidative stress, vascular inflammation, neurological risk, and impaired recycling pathways.
PATHWAY 01 · MTHFR + HOMOCYSTEINE
When methylation pathways are stressed, homocysteine can become a visible clue — not the whole answer. This page frames MTHFR as part of a larger inflammatory genetics map involving nutrient demand, cytokines, vascular risk, neurological symptoms, fatigue, and complex chronic illness.
MTHFR is context, not destiny
A variant matters most when symptoms, labs, diet, inflammation, liver function, medication history, and nutrient transport all point in the same direction.
Inflammation changes the demand
Cytokines, oxidative stress, infection history, autoimmune activity, and toxin burden can raise the metabolic cost of keeping methylation and repair pathways stable.
