Vitamin B Slows Brain Shrinkage, May Delay Dementia

Taking vitamin B slowed the rate that the brain shrank in elderly people who had trouble remembering, University of Oxford scientists found in a study that may guide further research into Alzheimer’s disease.

Vitamins B6 and B12, as well as folic acid, lowered the levels of an amino acid called homocysteine that is linked to brain-cell damage similar to that seen in Alzheimer’s. Those with the highest levels of homocysteine in their blood showed the most benefit, according to the study published today in PLoS One, a publication of the Public Library of Science.
