Certain dietary supplements have been studied for stroke recovery and prevention. Multivitamins and nutrients like vitamin D, calcium, and vitamin C do not seem to prevent stroke. However, folic acid and B vitamin complex do seem to reduce the risk of stroke, especially in geographic locations that lack folic acid food fortification.[1] Fewer supplements, such as ginkgo and astragalus, have been studied for stroke recovery and evidence is inconclusive at best.[2][3]
Have any supplements been studied for stroke recovery and prevention?

Certain dietary supplements have been studied for stroke recovery and prevention, and folic acid and B vitamin complex have shown potential in reducing stroke risk, particularly in regions that lack folic acid fortification. In contrast, multivitamins and nutrients like vitamin D, calcium, and vitamin C do not appear to prevent stroke, and the evidence for supplements like ginkgo and astragalus for recovery is inconclusive.
