Summary:
Brain shrinkage is associated with memory loss
100 people age 61-87 were followed for 5 years for a study in Neurology
Those with low levels of vitamin B12 in their blood were 6 times as likely to lose brain volume as those with higher levels, though none were at B12 levels considered deficient
Conclusion: It’s not proven that B12 can protect your brain, but older adults should get at least 2.4 micrograms a day from multivitamins or fortified food
