Big Brain Benefit

Maintaining adequate levels of vitamin B12 and doing 30 to 45 minutes of aerobic exercise at least three times a week may help prevent brain shrinkage associated with aging.

For those over 50 who have trouble absorbing dietary B12, sublingual B12 or doctor administered (monthly) B12 injections from a doctor may be an option.
