Folic acid may reverse vascular aging and lower dementia risk

Folic acid, a B vitamin, may help maintain vascular and cardiac health by reducing harmful homocysteine levels. This nutrient breaks down homocysteine, an amino acid that can damage blood vessels, promote hardening, and hinder blood flow, potentially reversing vascular aging. Adequate intake, found in liver, soybeans, and green vegetables, may also lower dementia risk, according to research.
