Low Vitamin B12 Linked to Cognitive Decline

We’ve seen much information in recent years about the relationship between the B vitamins, especially B12, and cognitive function. But a new study fills in details about the mechanisms connecting low B12 levels and declining cognitive health. And one of the study’s authors has suggested that, while there is already a general recommendation for older adults to supplement with B12, there may be cause to advise middle age adults to do the same.

The mechanisms of cognitive decline associated with low levels of B12 include brain atrophy and cerebral infarcts (=blood flow blockage leading to tissue death). Other recent research has suggested that supplementing with B12 may slow brain atrophy as we age, so the current study linking low B12 levels to greater degrees of brain atrophy is not a big surprise.

The Institute of Medicine, an organization that establishes recommended daily allowances for vitamins, currently advises older adults to supplement with Vitamin B12, since seniors frequently are deficient in the vitamin due to declining ability to absorb nutrients. But according to one of the current study’s authors, it may make sense to screen adults for B12 deficiency even before they reach senior status, and address early signs of deficiency with supplementation.

NYBC stocks Vitamin B12 as in a highly absorbable form:

Methylcobabalmin

Also available is the B-complex:
B-right (Jarrow)
