Can vitamin B-12 improve memory in Alzheimer’s disease?

Vitamin B-12 helps maintain healthy nerve cells and red blood cells and so its deficiency can cause various signs and symptoms, including memory loss. In such cases, vitamin B-12 supplements can help improve memory.

In case there is no vitamin B-12 deficiency, no evidence suggests that vitamin B-12 supplements helps in enhancing memory for people who have Alzheimer’s disease.
