Aliquot #134: Why Homocysteine Accelerates Brain Aging
Elevated homocysteine levels often slip under the radar during routine checkups, yet they quietly raise our risk for heart disease, stroke, high blood pressure, Alzheimer's, and even shorten our lifespan. About one in ten adults carries a common genetic variant that makes it harder to clear homocysteine from the body. In this Aliquot, I explain exactly what homocysteine is, how it impacts both cardiovascular and brain health, and how simple nutritional strategies—like supplementing with vitamins B6, B12, and methylfolate—can help bring levels down, supporting healthy aging and sharper cognitive function.
