Dietary Supplement Intake Folate and Vitamin B12 Status and Cognitive Impairment Among Older Adults National Health and Nutrition Examination Survey 2011–2014

摘要

Cognitive decline is a major public health issue among older adults. Dietary supplement use is common among older adults, and a concern has been raised about high folic acid intake among those with vitamin B12 (vB12) deficiency and exacerbation of cognitive decline. We evaluated supplement intake and folate and vB12 concentrations among older adults with measured cognitive function.
