  • Title: Effect of short-term vitamin (folic acid, vitamins B6 and B12) administration on endothelial dysfunction induced by post-methionine load hyperhomocysteinemia.
    Author: Chao CL, Chien KL, Lee YT.
    Journal: Am J Cardiol; 1999 Dec 01; 84(11):1359-61, A8. PubMed ID: 10614808.
    Abstract:
    This study showed that short-term vitamin administration effectively reduced post-methionine load homocysteine levels and thereby ameliorated endothelium-dependent flow-mediated vasodilation in 16 healthy adults. Post-methionine load homocysteine levels decreased from 22.7+/-3.8 to 17.0+/-2.1 micromol/L (p <0.001), and flow-mediated vasodilation after methionine load increased from 8.6+/-3.6% to 13.8+/-2.9% (p <0.001) after vitamin administration.
