Stroke
Supplements studied for stroke.
Overview
Several supplements have been studied for stroke prevention and recovery, with varied results. Vitamin B9 (Folate) carries medium ratings and may slightly lower stroke risk, mainly in countries without folic acid fortification and in people with low folate, high homocysteine, or related risk factors. Ginkgo also carries medium ratings and may aid recovery after ischemic stroke when combined with standard treatment, including improved movement and daily functioning in some trials.
Vitamin B12, vitamin D, and green tea carry low ratings. Supplemental B12 has not clearly prevented stroke in most studies, though one review suggested a small reduction in at-risk groups. Vitamin D supplements do not appear to lower stroke risk despite links between low levels and higher risk. Green tea may modestly reduce stroke or post-stroke mortality at moderate intake, but findings are inconsistent. See the heatmap and evidence reviews below.
