B12
-
A 2009 study from the University of Toronto's Department of Neurology found that vitamin therapy (2.5 mg of folic acid, 50 mg of B6, and 1 mg of B12) did reduce the risk of nonfatal stroke in approximately 5,000 participants. However, the same study showed that in participants that did have a stroke, the vitamin therapy did not lower the severity of stroke or any stroke-related disability.

Recovery
-
In an article published by the Oxford University Press on behalf of the British Geriatrics Society, a 2006 study concluded that increasing levels of B12 following a stroke would be appropriate, though there was no conclusive evidence that an increase in the vitamin following a stroke would aid in recovery, specifically in lowering homocysteine levels and decreasing the risk of dementia.
