Folic Acid Supplements Reduce Risk of Alzheimer's by 55%

In a 10-year study, researchers evaluated the benefit of taking folic acid against the risk of developing Alzheimer's Disease.  The study was based on dietary information collected from 579 people ages 60 and older that showed no sign of Alzheimer's disease at initiation of the study.

Subjects kept a diary of food consumed during a typical week and indicated whether or not they were taking supplements that contained folic acid.  Researchers recorded this data over a period of 10 years.

During the 10-year period, 57 people were diagnosed with Alzheimer's.  Researchers said those subjects who were getting at or above 400 micrograms of folate per day had 55% lower risk of developing Alzheimer's than those who were consuming less than that amount.  The team of researchers also noted that most subjects were able to achieve 400 micrograms or more only by taking a supplement.
