Meeting the minimum requirement for vitamin B12, needed to make DNA, red blood cells and nerve tissue, may not actually be enough – particularly if you are older. It may even put you at risk for cognitive impairment.
The article, written by Suzanne Leigh and published on the website of the University of California - San Francisco, is very interesting. A new study, led by UC San Francisco researchers, found that older, healthy volunteers, with lower concentrations of B12, but still in the normal range, showed signs of neurological and cognitive deficiency. These levels were associated with more damage to the brain’s white matter – the nerve fibers that enable communication between areas of the brain – and test scores associated with slower cognitive and visual processing speeds, compared to those with higher B12.
