What are the recommendations for B vitamin supplementation in patients with recent stroke or TIA?
Results from VITATOPS (Vitamins to Prevent Stroke) and VISP (Vitamin Intervention for Stroke Prevention) did not show a significant reduction in risk of secondary stroke among patients with recent stroke who were randomized to receive various doses of folic acid and vitamin B supplementation. Thus, randomized trials of B vitamins for secondary stroke prevention are needed in patients with stroke or TIA who do not consume folate-fortified foods.
