A study published in the September issue of the journal Neurology proposed that higher vitamin B12 levels might protect the elderly against brain shrinkage. Researchers from Oxford University found that people in the upper third of vitamin B12 levels were 6 times less likely to experience brain shrinkage than those in the lowest third. These results suggest that older adults with B12 levels in the high normal range may be protected from the cognitive degeneration associated with senior dementia or Alzheimer’s disease.
The study involved 107 healthy people ages 61 to 87 who underwent scans to measure brain volume and gave blood samples to assess vitamin B12 levels once a year for up to 5 years.
While the study’s authors insist that it is too early to advise people to take extra B12 to prevent brain shrinkage, they do recommend that patients keep their levels within the normal range. Maintaining normal B12 levels can be achieved by eating foods rich in the vitamin, like dairy products, fish, meat and fortified grains as well as by taking a daily supplement. Vitamin B12 deficiency, which can lead to anemia and neurological damage, is uncommon in developed countries except among the elderly, who have problems with vitamin absorption, and among vegetarians, whose dietary intake may be low.
The initial studies with Poly-MVA (of which vitamin B12 is one of the key components) and its protective effects has researches excited how this supplement could play a significant role in many neurological conditions. Not only does it have cellular protective effects but it also supports the basic energy production of every cell which could lead to tremendous advances in degenerative disease and neurological conditions.
