Study Finds Vitamin B May Protect Against Alzheimers & Dementia

Study Finds Vitamin B May Protect Against Alzheimers & Dementia

May 20, 2017

Alzheimer's disease is currently at epidemic proportions, with 5.4 million Americans — including one in eight people aged 65 and over — living with Alzheimer's disease.1 By 2050, this is expected to jump to 16 million, and in the next 20 years, it is projected that Alzheimer's will affect one in four Americans.

While the cause of this condition is believed to be a mystery, it's becoming increasingly clear that what you eat, or don't eat, can influence your risk as well as the rate at which the disease progresses. B group vitamins, in particular, especially folic acid and vitamins B6 and B12, are again making headlines for their powerful role in preventing Alzheimer's disease.


Findings at a glance:
  • B vitamins may slow brain shrinkage by as much as seven-fold in brain regions specifically known to be most impacted by Alzheimer’s disease
  • High levels of the amino acid homocysteine are linked to brain shrinkage and an increased risk of Alzheimer’s; B vitamins are known to suppress homocysteine
  • Among participants taking high doses of folic acid and vitamins B6 and B12, blood levels of homocysteine were lowered as was the associated brain shrinkage – by up to 90 percent
  • Folic acid is a synthetic type of B vitamin used in supplements and fortified foods, while folate is the natural form found in foods; if you take a B-vitamin supplement, make sure it contains natural folate rather than synthetic folic acid
