Vitamin B12 lack linked to accelerated cognitive decline: Tufts study
Posted on December 5, 2012 by Stone Hearth News

Newswise — BOSTON — Being mildly vitamin B‐12 deficient could be an  indication that some older adults are at a greater risk for accelerated cognitive decline, an observational study from researchers at the Jean Mayer USDA Human Nutrition Research Center on  Aging (USDA HNRCA) at Tufts University suggests.
Martha Savaria Morris, Ph.D., an epidemiologist in the Nutrition Epidemiology Program at the HNRCA at Tufts University, and colleagues examined data from 549 men and women enrolled in a cohort of  the Framingham Heart Study, focusing on scores on the Mini‐Mental State Examination (MMSE), a short list of questions and tasks commonly used to screen for dementia. The subjects were divided  into five groups, based on their vitamin B‐12 blood levels.

B Vitamins: ATP Production and Adequate Intake

B Vitamins: ATP Production and Adequate Intake

Water-soluble B vitamins are collectively referred to as “B-Complex.” They include thiamin (B1), riboflavin (B2), niacin or niacinamide (B3), pyridoxine (B6), folic acid, vitamin B12, biotin and pantothenic acid (B5). Each of the B vitamins has its own functions to serve 
in the body, but in general the B complex plays a collective role in energy metabolism. This generally occurs after the B vitamins are metabolically converted into their active, coenzyme forms. Some are facilitators of the energy-releasing reactions themselves within the mitochondria, while others help build new cells to deliver the oxygen and nutrients that permit the energy pathways to run.
