Pharmaceutical Review (www.pharmarev.com). Many people are aware that vitamin B12 status declines during aging, as millions of seniors fall prey to a decline in this critical nutrient. Vitamin B12 circulating in the blood declines in the elderly due to absorption problems in the digestive tract leading to poor uptake by body tissues, especially the brain. Researchers have established a definitive link between poor vitamin B12 levels and brain shrinkage, a hallmark of cognitive decline and Alzheimer’s dementia. Supplementation with the biologically active form of the B vitamin may help prevent shrinkage and preserve learning capabilities and memory functions as we age.
The study involved 121 participants from the Chicago Health and Aging Project who underwent magnetic resonance imaging (MRI) scans for over a period of four and a half years. Additionally, each member of the study had blood drawn to measure levels of vitamin B12 and B12-related markers that can indicate a B12 deficiency. The same subjects took tests measuring their memory and other cognitive skills.
