What supplements have evidence for lowering homocysteine?

Folate (folic acid), vitamin B12, and vitamin B6 effectively lower homocysteine levels, with folate being the most potent. A combination of folate (400–800 mcg), B12 (500 mcg), and B6 (25 mg) can reduce homocysteine by 20–30%. However, whether lowering homocysteine with B vitamins reduces cardiovascular events remains debated.

Can B vitamin supplements alone reduce cardiovascular risk from high homocysteine?

B vitamins effectively lower homocysteine levels, but most large RCTs have not shown that this translates to reduced cardiovascular events in Western populations. The CSPPT trial in China (where food fortification is absent) did show stroke reduction with folic acid. The clinical significance may depend on baseline folate status and population.

When should someone with elevated homocysteine see a doctor?

Consult a doctor if homocysteine is above 15 micromol/L. Elevated homocysteine may indicate B12 or folate deficiency, kidney disease, or genetic conditions like MTHFR mutations. A comprehensive evaluation including B12, folate, kidney function, and cardiovascular risk assessment is important for determining the best management approach.

About

Elevated plasma homocysteine levels (>15 micromol/L) resulting from impaired one-carbon metabolism. Homocysteine directly damages endothelial cells, promotes LDL oxidation, and activates pro-thrombotic pathways. An independent risk factor for cardiovascular disease and stroke.

Common Symptoms

Usually asymptomatic Associated with premature atherosclerosis Thromboembolism

Risk Factors

Folate/B12/B6 deficiency
MTHFR C677T polymorphism
Chronic kidney disease
Hypothyroidism
Certain medications (methotrexate, phenytoin)
Advancing age
