“The B-vitamins, particularly folate, vitamin B12, and vitamin B6, are widely believed to be protective against Alzheimer’s disease and age-related cognitive decline,” began the study.
“Current interest in vitamin B12 and folate as risk factors for dementia is based on their relations as co-factors in the metabolism of homocysteine.
“Homocysteine has been related to the risk of developing Alzheimer’s disease in some.”
