Recent research shows that large doses of B-vitamins could slow cognitive decline in older people. Such a mental decline can be the precursor to dementias such as Alzheimer's disease.
The research found that large quantities of vitamins B6, B12 and folic acid reduced overall brain shrinkage by 30% over the course of the two-year study.
According to The Guardian:
“Taking B vitamins and folic acid is known to control the levels of an amino acid called homocysteine in the blood. High levels of this chemical can damage blood vessels and are associated with increased risk of dementia.”
