Folic acid and reduction of plasma homocysteine concentrations in older adults: a dose-response study.
BACKGROUND: Elevated homocysteine concentrations, a likely risk factor for cardiovascular disease, can be lowered effectively with folic acid. The minimum dose of folic acid required for maximal reduction of homocysteine concentrations is not yet known reliably. OBJECTIVE: We aimed to determine the lowest folic acid dose that decreases plasma homocysteine concentrations adequately in healthy older adults. DESIGN: A dose-response trial with a randomized, double-blind, parallel-group, placebo-...Expand abstract
