Tufts Study Links B Vitamins to Brain Health and Dementia Risk

Emerging research from Tufts University highlights the critical role of B vitamins, especially B12 and folate, in maintaining brain health and preventing cognitive decline. Vitamin B12 supports nerve health in the brain and spinal cord, with deficiencies linked to memory loss and dementia. Folate aids DNA production and cellular metabolism, with low levels increasing dementia risk. By age 75, about 40% of people have reduced ability to absorb vitamin B12 from food, raising the risk of silent deficiencies affecting cognition. Dr. Irwin H. Rosenberg notes that many dementia cases attributed to Alzheimer’s may actually stem from nutritional deficiencies, particularly B12 deficiency. B vitamins also protect the brain from damage caused by strokes and cardiovascular disease, with some evidence suggesting folate supplementation can lower stroke risk. Vitamin B6 may reduce chronic inflammation, a factor in heart disease and brain degeneration. Unlike costly genetic tests or drugs, B vitamin supplementation is inexpensive and accessible, making it a simple strategy to support brain health. Tufts researchers emphasize that age-related memory loss involves not only Alzheimer’s but also vascular issues and vitamin deficiencies, especially of B vitamins.
